Title: Project RM175F
Post by: monaro308 on February 08, 2010, 01:12:29 am
Made a start on my next project during the week...PE175 engine out of my "on the back burner" 83' PE175D....i think it is actually an "E" engine going by the numbers i have and the 85' RM125F bitsa with a destroyed engine. 80% of the bike is there.....so i thought why not!
Now that i'm on arvoshift,a man needs a project to keep himself occupied  ;D
Rear shock was blown on both bikes,so that was a bad start :'( and it is an RM250 shock after sorting out parts for it.

The RM engine being w/cooled (no fins)and centre exhaust port against the PE,big finned air cooled and angled port....the frame is gonna be getting a good workover.
First thing was the engine wouldn't fit in the frame because of the big finned head and barrel (good start)  ::) so off with the top end and sit the engine in with the PE rear engine mount bracket.
(http://i199.photobucket.com/albums/aa250/hjcoupe/rearmount.jpg)

All good and even the bottom case mount lines up with RM frame mount.

(http://i199.photobucket.com/albums/aa250/hjcoupe/rhside.jpg)
Front case mounts to frame will need to be made up.
Fitted the swingarm into the frame and that bolted straight in with the PE bracket! Too easy  ;D
Wrong!! Then i noticed the engine sprocket being further outboard.
I measured up the PE cases against the RM cases...hmm PE engine is wider by about 10mm.
Fitted the rear wheel and "lasered" up the rear sprocket to the front sprocket...yep she's out alright!

(http://i199.photobucket.com/albums/aa250/hjcoupe/laserline.jpg)
So out came the PE bracket and i've been making another bracket to move the engine over to the right side and rebuilding the rear shocker over the weekend.

More to come......

Hi monaro 308, I have had "three" pe175's during my life! they were mainly used for work hacks, at the time. Their trail ability really suprized me when I had the odd chance I to venture off road. I rebuilt the trunion suspension set up on one of the single shock set up's once!!!!!!! nearly had to sell the first born!!!!!!!!!$$$$$

Hi Mick...yeah the PE served me well in the 80's (PE175X)for 9 years and a workmate had the D model floater he was going to offload so i said yes knowing the floater linkages are a VERY costly exercise.
The whole bike has been abused BADLY and i mean bad!
It will get done oneday in dribs and drabs....no hurry.

The RM bitsa cost me $200 even with a brand new Dunlop756 on the rear.....and then the mind had visions...hmm PE175 engine and lighting capability,bitsa RM125 bike with yummy 43mm forks and front disc and i need another project on arvoshift  ;D
The front downtube side of things it going to be the tricky part clearing the barrel and head and angled ex-port,although being semi-cradled the right downtube may remain if i can make the left side look nice with maybe a loop for the pipe to enter the ex-port....we'll see..early days yet!
More to come!

This is the tight squeeze of the PE engine into the 125 frame.
The diagonal frame tube is going to come out,but i will work out how much and if i can save the airbox bracket part of the tube i will.

Rear mount brackets made up

(http://i199.photobucket.com/albums/aa250/hjcoupe/lheng.jpg)
(http://i199.photobucket.com/albums/aa250/hjcoupe/rheng.jpg)
I had to double plate the bracket and step it in to move the engine to the right to line up the front sprocket to the rear.
(http://i199.photobucket.com/albums/aa250/hjcoupe/stepbracket.jpg)
I will weld the support in the centre once everything is correct.

this is all food for thought Mario, keep it coming 8) Ironically it would seem I'm about to become the owner of an '84 RM125E for much the same coin as yours. The top end is missing but apparently the rest is all there. Depending on what the engine and the rest of the bike is like it could end up a project also if it's all too far gone ;)

Bahnsy is that a PE engine or a modded PE top end on a RM bottom....if that can be done cause i think the stud spacing is wider on the PE's....not sure on that one.
Hows it go and are you happy with it?

Thats great Doc....i think they are pretty much the same bike.
85 had the disc front and 84 has the twin leading shoes.
I'll keep posting pics....as i'm a stubborn prick and once i get something in my head i'll keep at it.
If it turns out well,the added bonus of getting a lighting kit on it to get rec reg may make it a keeper and possibly say goodbye to the 06 WR450F....its a great bike but its a $6000 bike that doesn't get used alot.
Post your pics in here when you get it.
Cheers....i better get to bed!

Nice job so far, you are almost there, remember it only has to miss everything by a couple of mm or two.

Keeping the airbox downtube is well worth it, you end up with a mini RN500.

Post by: TT on February 10, 2010, 10:05:28 am
Yeah, well done. I love this sort of stuff.
The only special I ever built was an XT200 engine in a PE chassis.  ::)
Don't ask why, as I'm still asking myself the same question.
I guess because it was another bike to ride that cost virtually nothing.   ;D
Title: Re: Project RM175F
Post by: monaro308 on February 10, 2010, 01:05:52 pm
Tony....that is the key "I guess because it was another bike to ride that cost virtually nothing" well i hope it turns out that way....lol

Marc i want to try and keep the airbox tube there even to the point of cutting about an inch at the top and bottom and slightly turn the tube and reweld to clear the head as its even bigger with the finning.
I'll make up the front mount plates next and spacers for the bottom mounts between the case and frame tabs.
I'm debating on using alloy plates or steel plates....i suppose alloy because of vibration,but as usual,when i need my TIG (just a cheapy china brand but works well for what i need)i run out of Argon!
I started to tig the rear mounts and just run out of gas,so out came the 30y/old WIA arc...lol
Nothing a can of black and silastic beading to give it that "A" grade tig look  ;D can fix.
cheers
Title: Re: Project RM175F
Post by: Marc.com on February 10, 2010, 02:56:46 pm
can you cut and knock the frame tube a bit at the top and still get the airbox in.

Don't worry about your welding you can't do any worse than Suzuki, drunk with the cheapest Chinese welder.

What are you using for a gas tank ?? ;D

Post by: BAHNZY on February 10, 2010, 03:27:45 pm
The bike is/was a 1983 PE175.
Whilst I considered the route of using the 84 Chassis (I’ve got a few of them) i didn’t see that the work to get the engine into the frame and the associated work was worth my time. So what was built is;
- A stock 83 PE175 frame and swing arm with the loop removed from behind the seat.
- Fitted a 84 RM125 shock (less the remote reservoir)
- The frame was then modified to accept the complete plastic kit from a RM465
- A RM125N fuel tank was fitted.
- Top-Line Motorcycle Upholstery then made a foam to suit the seat tank junction and covered the seat.
- The engine is a ported RM175 engine with Boysen Reeds and a 1.0mm o/s Wiseco.
- Expansion chamber was sectioned and the baffles, etc removed. Pro Circuit supplied the rear muffler.
- Gearbox is from a RM125C
- Front suspension is standard 83 PE but will be swapped out for a 43mm RM125 unit when I get a chance.

Bike is set up for my daughter at 70kg and does the job real well. When i get on it the poor thing struggles, i'll stick to my PE250T.

marc i think you better give me that tank for my bike ;D
it will look better on my bike :D
you dont need it ;)


it will fit if i can fit a 500 engine in same frame it will fit ;)
Title: Re: Project RM175F
Post by: monaro308 on February 11, 2010, 02:14:45 am
Bahnsy i have what you made  :)
This is the PE thats on the backburner until a later date.
Every single part needs doing.
(http://i199.photobucket.com/albums/aa250/hjcoupe/PE.jpg)

Ty4 thanks for the offer as i have B,T,X and the F front mount plates and they all don't match the engine to frame and i'm sure i will have to make new plates for it.......but i'll keep you in mind for sure.

Marc i can pretty much remove most of that tube.The bottom mount is at the front sprocket in the picture and the other 2 are top and the back.The airbox is a side mount access type.
I will try and mount the airbox tomorrow to see how far the boot and the angle of the boot is to where the carby will be....but that tube needs to go before i can sit the cylinder on the cases.
I may be able to notch out the back of that front downtube right where the top of the cylinder is in the pic and then the battle with the head begins.
Tanks i have to try are PE175D,the RM125F with the scoops because it was w/cooled,a RM125N,T tank,RM125C tank.
They all seem to fit pretty well if i make new mounts for them,then because of the RM safety seat it looks a little odd.
I thought about using the original F tank and then making 2 fake looking radiators as extra fuel tanks...just a thought at the moment.
Thats it for another day/night...thanks everyone  ;)

Gotta say that whilst the conversion of the PE to a "RM Looking" machine looks/sounds easy enough, the mods to get the RM rear guard and side covers fitted was a nightmare, but worth the effort.

Mario, i have the tank from that bike, (i replaced it with a slighty better condition tank with decals) if you want to check out the fit and form. Let me know if you are interested.

Rod
Title: Re: Project RM175F
Post by: monaro308 on February 14, 2010, 02:23:00 am
Hi Rod...late reply....just back from the Southern 80 (well 1/2 of it)and off to a 4 y/olds birthday party for Sunday  ::)
Once I'm ready for the tank/seat part i'll try what i have again,but i'll let you know.
In your earlier post you said you have a few 84 frames...was that RM or PE frames?
Just curious as i was keeping an eye on a 84 RM125 frame on ebay which is pretty much the same as the 85 i have here.
I just checked to see if i won as i put a bid in 2 days ago when i left for Echuca.....no other bids and i did win it for ....99cents  ;D
I am going to cut into the 84 frame now and use that instead,i also bid on the front forks (43mm)and triples just for the hell of it and won them for $20.50 even though they are drum front on the 84......good for spares and may go on the PE in the future  ;)

Anyway.....just before i left i finished the shock rebuild (RM250)and took it into work to recharge it with nitrogen.
(http://i199.photobucket.com/albums/aa250/hjcoupe/rearshock.jpg)

I pulled the spacer tube out of the rear cushion lever and noticed a few of the needle rollers were missing
and had to replace them and the 2 seals inside.
Suzuki wanted $30.00+ for each bearing (20x27x25) i got them for $33.00 inc gst for the 2 at my local bearing shop. NTN bearing # HMK2025
The genuine Suzuki seals were cheaper than aftermarket @ $7.00 each.
(http://i199.photobucket.com/albums/aa250/hjcoupe/rearcushion.jpg)

I also checked the swingarm bearings....same deal,but they take 20x27x20 bearings @$29.00 each genuine,and 4 seals.
Once again Suzuki seals were cheaper @$7.00 each,and i noticed there is a 10mm empty space between the outer seal,bearing and inner seal,so i was able to fit the another 2 of the above needle rollers 25mm wide against the 20mm and still have 5mm left....so $33.00 for the 2 again.
The strut bearings look and feel ok.....i'll check later on.
Thats it for now and i better get my arse into bed ready for a big day at a 4 year olds  :P
later.....

Mario,
I have bought 4 RM125's of various 84/85 vintages all in different states of diss-repair and avalaible parts. Essentially all i wanted was to make a honest reproduction of the bike that was used in the 84 world championship. The bike is now finished and i have a couple of spare frames, swingarms wheels etc left over and in two minds what to do with them.

I also bid on the parts from Bittern (i got the air box and the front wheel assembly) and was going to have a crack at the forks and fell asleep and missed them. If you are looking for anything specific let me know and i'll chase through the boxes of parts.

PS: If anyone is thinking about building a 84 RM125 and is looking towards sourcing 1985 parts as your mate told you they are the same bike, that Suzuki just changed a sticker kit, then be aware there is a significant amount of changes in the bike where parts won't interchange, particulary the engine and suspension. I learnt the hard way on this one.

Rod
Title: Re: Project RM175F
Post by: monaro308 on February 14, 2010, 08:09:45 pm
Ahh bugger Rod,sorry about the forks,i had no idea that i was going to win it,especially that i was away for 2 days.
I assume the frames were similar?
Looking at my rear shock....it has confused the hell out of me,is it an RM250  ???
Going by Alpha's pics,it looks like an 84 but with the wrong hose and resi.
The bottom alloy bit of the shock just above the banjo bolt looks different to whats on other RM's
Got me wondering what i now have.
homework to do.......................
Title: Re: Project RM175F
Post by: BAHNZY on February 14, 2010, 08:20:53 pm
Went down to Bittern to pick up the wheel and air-box and low and behold the seller (Paul) is a VIPER rider. \
Small World it is after all.
Title: Re: Project RM175F
Post by: monaro308 on February 15, 2010, 01:54:40 pm
Hey Rod it is a small world...picked up the forks and frame from Paul this morning and got talking.His mate that looks after his rally RX7 works with me!
Sounds like he is chasing another swingarm for his PE175D...has cracks around the s/arm pivot area...so if anyone out there has one,i will forward it on to him.

OK....straight into it,got the frame home and disassembled the 85 frame and hooked into the 84 frame.
Looks exactly the same but the shock resi bottom mount is narrower.I will modify that later.
I cut out the frame tube at the airbox to clear the barrel and head,but i left the bottom part of the airbox mount.
(http://i199.photobucket.com/albums/aa250/hjcoupe/airboxtube.jpg)

Sat the engine in the frame and only had to notch out the inner webbing of the front down tube.
(http://i199.photobucket.com/albums/aa250/hjcoupe/engfit.jpg)

Machined up 2 spacers for the bottom engine mount and pushed the PE bolt through (i will need the RM bolt as its shorter,anyone have one?? I'll get the lengths later)

(http://i199.photobucket.com/albums/aa250/hjcoupe/engspacers.jpg)

I sat the airbox in and the bottom back section hits the engine mount bracket....so this will need work.
(http://i199.photobucket.com/albums/aa250/hjcoupe/airboxtight.jpg)

Hits here...
Hey Rod if that airbox you got is average around that bottom area,let me know as mine is fine and i'd rather butcher an average one and give you mine.
(http://i199.photobucket.com/albums/aa250/hjcoupe/airboxcut.jpg)

Now this will need time spent here...
(http://i199.photobucket.com/albums/aa250/hjcoupe/downtubeeng.jpg)

Fitted up the dummy radiators to see for clearance around the head...all ok so i can think about making twin tanks for fuel...(if i really want to)
(http://i199.photobucket.com/albums/aa250/hjcoupe/radfit.jpg)
Thats all for today...off to work ::)

PS DOC...brackets got mailed out this morning to you

Post by: BAHNZY on February 15, 2010, 04:40:16 pm
Rather than replacing the bolt with a correct bolt, go for a length of all stainless all-thread and use some nylocks and washers on each side. Cheapest and easiest way around replacing those long specialist length Suzuki bolts.
Title: Re: Project RM175F
Post by: monaro308 on February 16, 2010, 01:39:36 pm
I thought about using all-thread but i'm not sure of the damage that the thread can do to the engine casing holes internally.....vibration does magic things when the two don't gell.
I'll put my wanted list up soon in the wanted section,because the fun now starts..........

I cut the drain section off the back of the airbox to clear the back mount.
It now fits nice and i will blank it off later with a small drain tube.
(http://i199.photobucket.com/albums/aa250/hjcoupe/airbox.jpg)

Now with the boot on,it actually lines up to the inlet almost spot-on,but i have less room for the carby to fit.
(http://i199.photobucket.com/albums/aa250/hjcoupe/airboxtocyl.jpg)

This is with the original PE carby
(http://i199.photobucket.com/albums/aa250/hjcoupe/roundslide.jpg)

This is with the flatslide that came with all the parts....
A VM34SS I need the top cover and slide and needle...all missing
(http://i199.photobucket.com/albums/aa250/hjcoupe/flatslide.jpg)

With the flatslide i have about 10mm more room and will most likely go this way if i can find the slide,needle and cover bits.
The PE inlet rubber is a straight shot and the RM rubber is angled.The RM one helps the carby clear the side of the airbox but puts the angle out.The PE one is good and the side of the carby just rubs on the airbox.5mm spacers on the airbox-frame will clear it.
(http://i199.photobucket.com/albums/aa250/hjcoupe/perubber.jpg)
(http://i199.photobucket.com/albums/aa250/hjcoupe/rmrubber.jpg)

Thats as far as i got today and all these little things are going to be the time consumers.
I have to work out what to do to shorten the airbox rubber to connect to the carby.
Once that is done the next issue is expansion chamber....that is gonna be a beauty to sort out.
The rest is pretty much bolt on stuff and the lighting side of it will be last.

Thats it for another day and its slow going from here on in.
Cheers....Mario
Title: Re: Project RM175F

Back again  ;D
I cut the airbox boot to where i needed it.
(http://i199.photobucket.com/albums/aa250/hjcoupe/bootready.jpg)

I taped up the two pieces to hold it together and applied Sikaflex/urethane to the outside,and then let it set for a day. (No matter how hard you try to avoid getting that sh1t on you with gloves and all....it ain't gonna happen!)
(http://i199.photobucket.com/albums/aa250/hjcoupe/boottape.jpg)

Trial fitting and i ended up using the RM angled inlet rubber as it sat better after curing.
Airbox bolted up fine and the boot fitted on the carb ok without much pressure.
I'll keep it on for a few days and keep an eye on the boot to see if it holds up,I might do another layer of urethane if i'm not happy.
(http://i199.photobucket.com/albums/aa250/hjcoupe/bootfitted.jpg)

I started to do a rough assembly of the bike to get and idea of what it might look like....
Check out  "Make Me A Super Model" topic.

Later...Mario

Thats the problem Doc,i seem to ignore other crap going on around the house and jump into my projects.
Always been like that and don't know when to stop and i'm not the type to just sit around and watch TV (unless Collingwood is playing  ;D)then i go watch it in the shed  ::) i enjoy working on bikes instead of cars everyday.

Were the brackets correct Doc? Hope so and better you using them than sitting around.

Hi Tony,alpha-sports show it as a 150x8mm bolt...and i didn't even think about jap cars,good point  ;)
I'll measure up the rear mounts too because i used slightly thicker steel than what the PE had,the nuts bottom out to soon.
I might tackle the front mount plates this weekend.....maybe the pipe too
Thanks.....mario
Title: Re: Project RM175F
Post by: monaro308 on February 28, 2010, 11:08:36 pm
The time consuming stuff has begun.....
I cut the cradle section out so i can make a start on the pipe.
(http://i199.photobucket.com/albums/aa250/hjcoupe/framecut.jpg)

I have 4 pipes to try out.....the RM125F pipe.Being a watercooled pipe there aint no way that expansion chamber will fit where the head is...so out it goes.
(http://i199.photobucket.com/albums/aa250/hjcoupe/fpipe.jpg)
Next the PE pipe,logical choice but i don't want to cut it as i will rebuild the PE "oneday" ::)
(http://i199.photobucket.com/albums/aa250/hjcoupe/pepipe.jpg)
The dunger RM125A/B pipe that i got a few weeks ago.Skinny expansion chamber and snakes through the frame.....not convinced.
(http://i199.photobucket.com/albums/aa250/hjcoupe/bpipe.jpg)
Finally an RM125T/100X pipe that i got with the RM125T ages ago.The expansion chamber is about the same size as the PE pipe but the header section is a smaller diameter.Someones had a go at the stinger section with an arc welder or a seagul with the runs.
This is good enough for the project as i have to cut it all up in sections.
(http://i199.photobucket.com/albums/aa250/hjcoupe/tpipe.jpg)
(http://i199.photobucket.com/albums/aa250/hjcoupe/tpipecut.jpg)
The RM pipes snake through the frame which is no good as the airbox takes up all the left side.
The end of the expansion chamber begins to taper off to the left which will make my stinger hit the frame rail.So i had to cut the centre section and flip it around so the taper now goes to the right.
(http://i199.photobucket.com/albums/aa250/hjcoupe/expflipover.jpg)

Title: Re: Project RM175F
Post by: monaro308 on February 28, 2010, 11:26:11 pm
Continued......
Expansion to header section tacked and welded up.
(http://i199.photobucket.com/albums/aa250/hjcoupe/exptacked-1.jpg)
(http://i199.photobucket.com/albums/aa250/hjcoupe/exptoheaderwelded.jpg)
Pipe dummy fitted the frame and engine.The first section of the header is still tacked and i need to weld a bigger ring that enters the ex/port due to the PE's larger ex/port size.
(http://i199.photobucket.com/albums/aa250/hjcoupe/expdummyfit.jpg)
Next up the stinger....i knew that Hills swing set gal pipe from my nephews would come in handy oneday  ;)
(http://i199.photobucket.com/albums/aa250/hjcoupe/stingerfit.jpg)
With sidecover fitted...
(http://i199.photobucket.com/albums/aa250/hjcoupe/stingerandnplate.jpg)
Now after much thinking over the seat tank combo,i thought to myself if i keep the original w/cooled seat-tank combo,with the radiators gone,i can fit the battery on one side and maybe still do a dummy fuel tank on the otherside and use the shrouds to cover it all up....will see later on,although i haven't tried the other tanks on the made up pipe.

Thats it for another week...more to come !
Title: Re: Project RM175F
Post by: LWC82PE on March 01, 2010, 01:52:17 am
A battery? Im guessing you want that for lights etc for road use? In that case on the otherside you could make an alloy tank for either extra fuel in addition to the small RM tank or a tank oil for pre-mixing so you dont have to carry a bottle in your back back or what ever on a trail ride.……..interesting.

Correct Leith  ;) if it all goes well and the bike goes well,i'm thinking about getting rec rego for it so i have no hassles in the bush from the men in blue.
My original idea was to run the twin fuel tanks in the shape of the original radiators for extra fuel because of the MX's tank capicity.
I'll try out the other tanks today with the pipe now 95% done and see how they fit...the PE tank would be the pick (10 odd lts).
If i had a longer remote resi hose i could move that to the left side like the PE US bikes have on the right side(as you told me),i could possibly fit the battery lower (which i prefer).
I think i still have all the lighting gear/loom i made up in the early 90's for my 88 KX250 as you could buy a lighting coil from the KDX from memory and make that work,but i never went ahead with the coil,but i did take the KX for a spin on the road once  ;)....that 88 KX 250 engine was a pearler,hard to keep that front end down...lol
Stay tuned!

Continued.......
I thought i'd take a break from the mechanical side of things and get stuck into the wiring.
The loom that came with the PE is a shambles so i went through my old junk and found the set up that i made for my old 88' KX250.
Luckily 95% of it was still there.....all after market stuff and all usable.
I pulled it all apart and decided to make another loom and copied the diagram off the PE175 courtesy of LukeB's info (thanks Luke ;) ) It was all fairly straight forward except my switch gear wiring colours are different to the PE switch gear asm....so a bit of tracing and matching did the trick.
I'm not 100% sure on rec rego rules (vic)regarding the bike just needs to have working lighting,i decided to make the whole loom with indicators,horn,speedo light...etc

Next up the battery!!
About 4 years ago i started a honda CT90 trail rebuild to use at Bathurst...since the V8's now bore me,it's been sitting since then,but i bought a new battery about 2 years ago (still dry) and a CT110 plastic battery box to see if it would fit into the CT90 frame....nope....but it does fit into an RM125F frame  ;D
I made up a plate to mount on the frame and i was able to use the original rubber mounting points of the radiator to help vibration on the battery.
I mounted the box onto the plate making sure it would (a)fit in the frame (b) clear the forks on full lock (c)let me use the radiator shrouds to cover it all up.

(http://i199.photobucket.com/albums/aa250/hjcoupe/batteryinbox.jpg)
(http://i199.photobucket.com/albums/aa250/hjcoupe/batteryshroud.jpg)

It all fits in and i'm able to lift the lid on the battery box.
I'll weld a bracket and nut on the exp/chamber to mount the shroud on the bottom and that side of it is done.
I'll suss out the aluminium factory for scraps and off cut sheets to think about an extra tank on the other side.
Thats it for another week....cheers Mario

Lol...yeah marc it will get done. I was thinking in the way of the BMWs and old CB hondas with the roll hoops in front of the engine  ;D
As Doc said the front engine plates and that downtube will get finished...sometimes you need a break from the mechanicals that drag on and on.
Lukeb....regarding your pm,yes the loom is fused,you can see it just to the right of the coil  ;D

Hey Doc what project have you got going on????? Did you end up getting that RM125?

My sisters house copped 2 broken windows and now has a golfball looking Hilux in the driveway(they are O/S at the moment) in Rowville after the hailstorm and all the other torrential stuff that went on in Melbourne,but i'm about 25kms from them and only got medium to heavy rain and not much else!
It was perfect wiring loom making weather ;D ;D ;D
Title: Re: Project RM175F
Post by: DR on March 08, 2010, 12:03:38 pm
Mario, lack of funds so the 125 was passed up. The 400 is a 2nd '78 RM400 project.  I rescued the motor out of a Honda Odyssey about 20 years ago as it had consecutive numbers to mine and I thought that too much of a coincidence to leave it alone. It's taken till now to actually do anything with it :P  doesn't have the alloy swingarm as they are in high demand so I've fitted a nice '76 370A tubular steel job. The front end is 38mm with 400N triples spinning on tapered rollers. The rest is pretty much stock 400C but in need of the full monty (excepting the engine ;)) Still hunting a few bits like a rooted or useable  370 or 400 pipe, cdi and stator unit, rear sprocket and a front plate and it's the complete deal. Sure beats watching TV :D

Of course I always check whatever is on don't let me stop you bidding on something I prefer to buy them privately though I haven't bought a PE of ebay but have tried several times it is good to sell on but makes buying a bit painful.

I secretly probably not that secretly want to get one of each PE which is 16 PE's of which I have 5 different kinds so 11 to go this 400 I am doing up is going to be the main rider if I see good ideas on yours I might pinch them for mine. ;)

But we need a bigger shed my PE's are on the back burner until I finish the gt80 which is starting to come together. :)

Back again....
Battey box all done
(http://i199.photobucket.com/albums/aa250/hjcoupe/battcomprear.jpg)
(http://i199.photobucket.com/albums/aa250/hjcoupe/battright.jpg)
Oneday i might change to the proper PE sized battery which is slimmer to the CT90/110 battery and box i'm using.
If it doesn't get smashed it can stay....we will see.
Next up i made the front engine plates.I had an aluminium plate just for the job.It is even the tougher T4??? grade x 6mm.
Since my laser cutting machine isn't working ::) ::) (joking) the hacksaw,drill,and file is my mode of tools.
(http://i199.photobucket.com/albums/aa250/hjcoupe/platesfront.jpg)
(http://i199.photobucket.com/albums/aa250/hjcoupe/leftplate.jpg)
The bolts may be temporary as the RM frame has given me the the luxury of maybe making up a bash guard as the bolt holes go straight through and also at the brake pedal guard bolt holes.
(http://i199.photobucket.com/albums/aa250/hjcoupe/plateright.jpg)

I thought i may be up for new sprockets as the PE comes with 12:48 @4:00 ratio
My engine has a 13 front and the RM rear is a 52T...which equals 4:00 ratio  ;D so all i'm up for is chain.

Thats it for another day...cheers Mario

Post by: monaro308 on March 17, 2010, 02:04:06 am
Frame time......
I was debating which way to go with the front section of the frame where the header section enters the barrel.
I wanted to use a ring/pipe type section to fill the gap.It got a little tight with the way the pipe snakes out and the ring would have been a little weak (maybe) and since i didn't have any pipe that size i decided to go with an outer loop/semi PE looking bash guard.
The pipe is the left over old frame section from the air box-backbone.
I put hacksaw cuts along it and bent it around to suit and welded it up again.
I had some stainless plate laying around (3 or 4mm)and cut sections out to brace it up.
Its not the prettiest design but a lick of paint always makes things look better  :P

(http://i199.photobucket.com/albums/aa250/hjcoupe/frameweld4.jpg)
(http://i199.photobucket.com/albums/aa250/hjcoupe/frameweld3.jpg)
Most of the hard stuff is nearly done and a re-assemble in the next day or two to make sure everything fits in. A general clean up of the plastics,new fork seals to buy,engine clean up etc etc.
I managed to find a TM34 carb from tassie and then located another in the US for $50 delivered.

Still sorting out the rear shock as i reckon the one i have is off something else(bike sits lower than it should) and Bahnsy kindly donated some left over '84 shock bits to see what i can come up with...although i have a spotted an '85 shock(needs rebuild) in the US which will fix my problem.
Thats all i have for ya's....cheers mario

Not pretty but will  get the job done, I guess the only pretty solution would have been to use the PE front frame section and covert it to single down tube, in fact you should go out and do that right now  ;D Anyway like you say once it is all the same color it will disappear.

I won't be hacking into the PE frame Marc,people will shoot me around here  ;D
Mind you,i do have an RM100X frame sitting in the shed doing nothing (YET ;))
Once it's painted and the exhaust is there it will all look normal...kinda like a person with a big mole on their face...you try not to look,but you just have to  ;D ;D ;D or like a mother still loves their really ugly child....it is the FRANKENBIKE!
If i score a knackered RM frame down the track,it can still easily be changed.

Left side radiator area will be taken up with an extra tank,water holder,stubby holder,melways,make up,
spare honda bits when my mates bikes break down....or....a water cooled head onto the aircooled barrel???? hmm and refit the LH radiator!
PE tank can fit on if i put the battery somewhere else.

Sorry for being blunt, but that frame mod is just plain fugly.

You would have been better off to extend the downtube down & then join the lower rails into it.
It wouldn't have been much extra work and you woundn't necessarily have had to butcher another frame for the tubing, just measure the size of the down tube, find some the same and find a sleeve to fit inside both.
You could cut & rotate the lower rails to join in.

It currently looks like a "backyard job" (sorry) but to have done it the other way would always have people guessing what it was.

Sorry Mario mate but I am with Geoff on this one, using old PE frame front rails would sort your front engine mounts, but Geoff is right man of your undeniable talents could do it all from scratch and make it look factory..

Mario,block out the 'constructive feedback' and continue with your project,and keep sharing your progress.

I think some people forget that we all have finite budgets, and not all of us can do a 'cheque book' restoration.There will always be a better way of modifying anything,but not all of us have unlimited funds to finance it.
Also everyones taste is different,i.e. some people think that Thor swingarms are butt ugly,but the only person who really counts at the end of the day,is the bike owner.

ALRIGHT ALRIGHT you bastards.... :P :P :P
GMC the reason it looks like a backyard job is because it's done in my backyard!

Marc that "handle" is the LH frame rail that was cut out and modified.

"IF" i go with the straight down tube,i know its fairly easy to do which i could have done....would anyone have noticed??
I bet once the engine goes back in and the pipe is there,it will probably look like a barrel/head protector loop for the big fat PE topend...i'll wait and see.
Mind you i do now have the luxury of fitting a centre port or offset port engine of my choice  ;)
I'll dummy fit it all today and take a piccy for you and see what you think.
I dont have the luxury of jigs,cut off saws,pipe benders and a rack full of chromemoly tubing to replace sections.
Remember this is a play/woods bike.
Its an easy change to the frame if i have to....keep em coming....i can take it! ;D

Well, I wasn’t bagging the project, just the frame mods and yes it was meant as constructive criticism.

“I think some people forget that we all have finite budgets, and not all of us can do a 'cheque book' restoration.There will always be a better way of modifying anything,but not all of us have unlimited funds to finance it.”
That doesn’t really come into it as Mario’s labour and costs are much the same to do it either way.

“I dont have the luxury of jigs,cut off saws,pipe benders and a rack full of chromemoly tubing to replace sections”
Yes, but I wouldn’t be using jigs or cut off saws to do this modification.
(Not using the Brobo at all at the moment since a tube grabbed and spun and I broke the effin blade. :-[ :()
The tube bender and Cro-mo on the shelf are handy but it's easy to work around that, just as you already have.

“but the only person who really counts at the end of the day, is the bike owner.”
I agree entirely.
But  ;D I think I have an old 78 RM 125 frame your welcome to as well if you want.

Whoa fella's......no ones bagging anyone here including you GMC....i'd love to have what you have because you've worked for it and thats your field of work.
So everyone....chill out its just a 4 inch section of frame.

Anyhow,I've gone out and done a refitting of the engine,pipe etc.....and i have to say with all the stuff back on,it doesn't stick out like a sore thumb and i'm gonna keep going with what i have.
The other thing i have just noticed/convinced me was because the engine is offset to the right nearly 10mm the much talked about down tube "looks" to be inline with part of the exhaust port...not a major issue but more work on either the down tube/header pipe or both.

Thanks for the offers TEX and GMC for the frames...i'll keep them in mind.
Huski you are right....bush bike..i've been hanging around "Thumpertalk" too much (in the 2 stroke/vintage) section of course  ;D

I'll upload some more pics later and see what ya's reckon...and thanks for ALL the comments

I am liking the project I may even steal a few of your ideas when I get my project started. ;)

I think whatever you do out of the ordinary people will talk about it is good to see the amount of work you are doing on it I am doing a few minor mods not major ones a disc front end which is off a ts250 or there abouts and that will fit using some 82-84 pe175 t/trees because they are 38 over the earlier 36mm. Also I am going to have the lighting made to 12V if I can might even make a new loom so that it feeds every thing as I think that a few items are feed only by the coil and not the battery.

Keep up the good work I think once your pipe is on and frame painted you won't even notice the modified frame keep posting your build and good ideas thanks Michael. :)

Of course that radiator won't be there,but something in the shape of that will be.

Michael i also thought about a 12V set-up but seeing that i don't even ride my WR450 in the dark,i can't
see the extra work i need at the moment (12v would be nice) ;) and it would be good to see your  project on here.
Are you selling that PE '84 frame? My PE '83 frame needs repairs around the kickstand area so i may/will be interested.
Doc i thought about a matching loop..but i think the pipe kills that idea.
Also i haven't forgotten your question about my RM100X frame. ;)
Thats all i have for now,so its back to re-assembling to get it mobile and do more work and i might be able to fire it up in the next week.Then it gets torn down again for a clean-up etc etc.
I haven't even checked if the kickstart fits in there yet ::)

Hi Mario, no I don't have the frame I bought the t/trees off it for my project but I do have a good PE 175z-e muffler if you need one I haven't been able to find one a floater to put it on.

I will post my project when I get it out the roof probably this weekend you know you could put a disc front end no probs on yours with my 400 I couldn't use many other trees becuase of them hitting the tank but a mate told me that pe 175z-e had 38mm insted of 36mm so I could use 38mm ts forks. ;)

Title: Re: Project RM175F
Post by: monaro308 on March 19, 2010, 09:06:33 am
Michael that muffler may come in handy.The one that came with my PE had a cut and shut done to it and no doubt the one i have on the RM175 is gonna be loud and i may keep the one you have for the PE.
I have the front end off an '84 RM...triples and 43mm forks which fit the PE front wheel.I know the steering stem shaft is different but i haven't checked the tank clearance now that you mention it!

you could always turbo it and put a intercooler
where the radiator is

i would try a rm 100/125 air cooled fuel tank it should go straight on
i fitted a rm500 tank on mine without much mods
then you can piss of radiatior shrouds and safety seat can be
easily modded to fit air cooled tank ;)

I will post my project when I get it out the roof probably this weekend you know you could put a disc front end no probs on yours with my 400 I couldn't use many other trees becuase of them hitting the tank but a mate told me that pe 175z-e had 38mm insted of 36mm so I could use 38mm ts forks. ;)



Is this the easiest way to put a disc front on a PE175Z? The whole front end off a TS?

Which year model TS250 will fit?

Post by: monaro308 on March 19, 2010, 12:16:58 pm
Holeshot i have all that stuff,check out the pics in my "make me a super model" thread a page or 2 back.
All easily changed if i move the battery.
I'll stay with what i have for now and if the shrouds survive in the scrub then it's all good.
I was thinking of a Nitrous bottle in there...could double as the extra fuel tank :P

Floberts i wouldn't mind knowing that answer too.

When i get a chance i'll dummy up the RM125E-F front end on the PE to see if the triples hit the tank(which i reckon they will) which will give another option (the 85 RM125 has disc and the 84 has twin leading shoes)but i've heard the 84 had a great front brake(some say too strong) and the 85 was so so with the single piston caliper.
I'll get back to you on that.
cheers...mario

The TS front end suited my 400 length wise it was just right but with some longer fork caps on them it will give me a bit of play either way but I am not sure of the seat hight of the pe175z-e I am tipping the 38mm TS forks would go but might have to come through the triples a bit more any one got a length of the stock shocks and I will tell you if the ts will work straight up on the 175.

The muffler I haven't been able to use looks a good one to it is in my shed somewhere if you have anything 400 let me know I think that it may be the only 175 stuff I have but I am not sure. ;)

I dropped a 84-RM125 43mm drum front end into my 1980 PE250, real simple swap. Pressed out the steerer tube from the RM lower clamp and same on the PE lower. Machined about 5 mmm of the bottom of the PE steerer then re-machined the groove for the circlip back in and pressed the newly modified steerer tube into the RM lower clamp then re-used all the old bearings and hardware.
This was done because;
- The 84 RM steering tube is way to long to use in the PE.
- The PE tube had to be machined down because there is about a 5mm variation in the lower tripple clamp thickness.
I then used the original PE wheel and brake plate, and machined up a couple of spacers for the front wheel. The trap here is that the brake cable comes out at a crazy angle as the spigot to locate the backing plate for the brake is in a different location than the PE. The fix for this was to use a 1982 RM250 front brake cable.

The end result is a front end that looks like it is meant to be there. In fact most people dont even pic the mod. The plus side is that i have a 80 PE250 with a 43mm front end, Old School Ohlins piggy backs and it rides as good, if not better then anything from that era.

The fork leg length of the 175Z is 1030 mm (not including the fork cap)

From the centre of the axle to the top is 912 mm.

Spacing between the triple clamp centres is 180 mm.

Does this all line up Frosty?

Post by: LWC82PE on March 19, 2010, 01:56:49 pm
TS forks  are shorter/have less travel than the PE forks. You need to change the TS inner fork tubes and/or damper rods to 1979/1980 RM  or 82-84 PE 175 parts to give correct travel for PE. TS200 or 85 RM front end is a lot easier conversion.

Continued.......
Had a bit of a bludge this weekend.
The correct ('85) shocker arrived from the US.....damn hard to find them being the only year for that shock.
After firing an email to the owner asking in what condition was the shocker and shaft...his reply...it is in usable condition  ::)
I pulled it apart.....worn shaft bush,blown seal,bugger all oil,bladder leaking past the cap. >:(
I was gonna reply back to ask "which part of the shock is usable?"
Anyway at least the body,resi and shaft are good and i aint sending it back knowing how hard it is to find one.
I had all the parts here when i ordered parts for the PE and the other mystery RM shock.
Cleaned it all up,re-bushed,re-sealed and put i all together yesterday and it now sits at the right height that it should be.
I re-assembled the bike again to continue with all the little odds and ends.
It is such an easy bike to work on.
I also picked up an TM34SS carby for $20.00 and changed the main jet to a 250,pilot to 25 as per PE175.
I will have to cross reference the jet needle and needle jet specs as the VM parts differ to the flatslide.
I'll keep the RM ones in until its time to sort it out.
I did a general clean up of the plastics and laid some black contact on the side covers.
I also had a play with home printer and made up these stickers on "windows paint",reversed the emblems and then printed on the back of the black contact and hand cut them.
It's only just to see what i can come up with and then maybe just buy the original decals when its all done.

After all the hoo ha about the downtube likes and dislikes,with everything just about on the bike now, i can honestly say....I LIKE IT ;D the bonus is that i can fit a centre port or an angled port if i want ;) ;)

Thats it for another weekend...enjoy

Assembled up it all looks a lot better, even the frame loop isn't that noticable now that the shrouds etc are in place. Are you going to do something about flattening out the seat to smooth the lines or are you rather short in the legs?

Title: Re: Project RM175F
Post by: monaro308 on March 23, 2010, 01:39:27 am
Thanks everyone  ;)
Tony27...yeah thats how they were back in them days.The RMs seemed to have that high look in the rear and 320mm rear wheel travel and 940mm seat height.
As i'm just shy off 5'7 and 72kg the plushness of the rear end gives me a nice one sided flat foot position compared to my 06 WR450 ...almost a semi tippy toed affair,included in that the signature top heaviness and a brick for a seat.
Although the RM feels too soft in the seat,but i'll wait and see how it feels on the trails.
I have a bad habit of riding sitting down alot....i find it uncomfortable riding standing on the pegs and my buggered left wrist from a hit and run on the road 25+ years ago on my PE175 left me with a fractured scaphoid.
Any load on my wrist really holds me up and it gets me down riding with mates as i know i'm holding them up,struggling to pull the clutch in or hanging on the bars up and down hills.
One of those Rekluse clutches may be the ticket for me oneday ....but i'll still go out.
After seeing how schmick Bahnsy's bike looked,i am tempted to spend money on it,but i'll restrain myself for now  ;D
Cheers....mario

All the fiddly little stuff is happening at the moment.
Welded up the header pipe and made all the little brackets and spring hooks on the pipe/muffler.
(http://i199.photobucket.com/albums/aa250/hjcoupe/exbrackets.jpg)

The shroud now bolts up to the battery case and ex/chamber.
(http://i199.photobucket.com/albums/aa250/hjcoupe/shrouddone.jpg)

Back together again for a pose.I made the 175 sticker a little larger and added  "Suzuki" to the shroud.
(http://i199.photobucket.com/albums/aa250/hjcoupe/outdoorpose.jpg)

Sat back and thought...nothing is stopping me firing it up.
Mixed a litre of fuel,made sure i had fuel flow,choke on....3 kicks and ping ping ping!!!!
(http://i199.photobucket.com/albums/aa250/hjcoupe/ITSALIVE.jpg)

Ahhh the smell and noise of a 2 stroke given a new lease of life ;D

A PE muffler is gonna be on the books as i hate loud bikes and jetting tweaks.
I'll have to make an small access hole in the air box to tune the mixture screw and then fit a plug.
I'll have to work out how many links i'll need for a chain and chase up a front chain buffer (there was a new one on ebay for $9 buy now but no email reply and was sold  >:() 

Left side shroud needs to be sorted out,fork seals and boots and little odds and ends,front tube and then pull apart for a clean up and put it all together again (lost count of how many times i've done that!)

Thats it for today....enjoy.

as for quiet, get a PE400 muffler, or make something of similar dimensions.
Excellent at keeping the racket down with no performance headaches.

e.g. here is my PE175N with a thumping great muffler that works very well indeed.

Thanks Luke.
I'll have to work with the sidecover thats on the RM.
I have an WR250F muffler that i can modify with a perforated centre or maybe the later oval WR450F type would fit better.
There are endless ways i can go.
Frosty may have a PE muffler that i can keep for my PE and then i can use the modded one that came with my PE.
Your PE looks great too.

Also a lot of guys use NOS or good used Pro circuit/FMF/Answer mufflers off ebay for later 80's bikes like KDX200 or enduro mufflers made for RM 250's etc and modify a mount or 2 and that way they have a cool looking functional and rebuildable alloy muffler at a a cheap price.

yep i know a few guys who have fitted later model aftermarket alloy mufflers to the full floater PE's. I dont know what models exactly but something for a late 80's/early 90's that just requires a bit of a bracket change.

Mario the later RGV250 mufflers are worth a thought also to retain the an OEM status..I hunt these down whenever possible. Along the way I've picked up a couple of nice lighter than air carbon fibre jobs also which were a bonus. Regular supermarket price is about $50 the pair ;)

Doc i occasionally look at RGV stuff just for the hell of it...well more because i used have a '91 M model and love the look of the banana swingarm...lol
There still seems to be a lot of interest in RGV stuff and gets the dollars for spare parts and i'll keep an eye out like you said.

Alls quiet on the bike build at the moment as i have been waiting on parts to arrive.
Luckily the carby problem has been sorted out which was a head ache and turned out to be the wrong jet needle (5+mm too short) and fuel was getting sucked straight out of the main jet.

Forks have been apart and cleaned up and ready to re-assemble.
Parts arrived today....fork seals,fork boots,uni filter,o ring chain,gear lever,pilot jets and needle/seat.

Trying to work out what fork oil weight would suit me....80kg with riding gear...any tips out there?
Next on the list is the extra tank/container to fill in the left side radiator shroud.
Also been sorting out the clutch and brake levers and the little petty things on the bike.
Barkbusters are also on the list.
I thieved the front tyre and tube from the PE and thats done.
So i'll get back into it tomorrow with more pics on the weekend.
cheers

Thanks Luke.I ended up getting 10w this morning and put them together.
Gotta hate it when you have to buy 2x1lt bottles @$42.00 because the forks take 550ml in each leg leaving me with a 900ml bottle  ::)
Oh well thats bikes for ya.

Post by: monaro308 on April 19, 2010, 12:05:04 pm
Back again!
After a busy week of work,vet visits,b/day parties...it was time to get back into the bike.
New fork seals were fitted and 10w oil put in and the forks re-assembled.
The new fork boots were also fitted to bling it up a little.Tyre and tube from the trusty PE175 (poor thing must feel like a prisoner that keeps dropping his soap in the shower)....not that i know what its like ;D
(http://i199.photobucket.com/albums/aa250/hjcoupe/Picture139s.jpg)

A set of Barkbusters arrived and were also fitted,i had to extend the right side bracket a little to clear the master cylinder fitting.I was worried if the bike was dropped,the clamp would snap the end of the m/cylinder fitting.
(http://i199.photobucket.com/albums/aa250/hjcoupe/Picture140s.jpg)

Next on the list was the left side shroud and what to put in the empty space  ??? ???
I had this stainless steel flexi cat/converter holder sitting around that fitted in the space available.
I also had my trusty Anaconda aluminium 1lt drink bottle that sat in the holder nicely  ;D
(http://i199.photobucket.com/albums/aa250/hjcoupe/Picture146s.jpg)
(http://i199.photobucket.com/albums/aa250/hjcoupe/Picture150s.jpg)
Welded up a couple of brackets to the rubber dampened fittings on the RM frame and brackets to the holder for the shroud to bolt up to.
(http://i199.photobucket.com/albums/aa250/hjcoupe/Picture151s.jpg)
All fitted up,the shroud sits in place nicely.If i use a long screwdriver to unclip the locks,the whole shroud swings open.
(http://i199.photobucket.com/albums/aa250/hjcoupe/Picture145s.jpg)
(http://i199.photobucket.com/albums/aa250/hjcoupe/Picture144s.jpg)

(http://i199.photobucket.com/albums/aa250/hjcoupe/Picture137s.jpg)

The real test will be out in the bush to find out how sturdy everthing is.If it all falls apart and is a pain in the butt,I'll end up fitting the PE tank and seat combo to give the extra fuel and less hassles.
Still have the little odds and ends to finish it off,but its almost there!
till next time  ;)

The cheque is in the mail 43 ;D.
Strangely enough this bike feels sooooo at home to sit in.
with nearly 13in of rear wheel travel that feels full floater "plush" a soft seat (maybe too soft) the whole seat,peg,bars fit feels great.
Even with the MX bars,i can stand on the pegs without looking like a monkey.
I have always like the feel of sitting in the bike and not on the bike.
I have never been comfortable on my 06 WR450F with the sit on top feel and a brick for a seat....i have even put it up for sale. I'd rather a $700 ish bike instead of a $6000.00 bike just sitting in the shed as i haven't had the time to ride it at all this year.

Time will tell how good this thing will be,but the fun is in building it.

A simple air cooled 175/200cc enduro engine in a proper mx chassis.

Still have the brake pedal and cable to fit....thinking about a different pedal as the standard RM pedal is a POS...and bends just looking at it!
I also kept the bash plate i made for my WR450F i just sold....it took bugger all mods to make it fit the RM frame.
The pipe has a couple of pin holes i need to weld up before it goes back on.

Yeah its a Maier headlight. They use aftermarket copy early Honda XR/early DR light inserts made by Xanadu in Taiwan.  Not to sure Maier are still making them, I tryed to get one 3 years ago and they were almost extinct then. Cemoto In Italy still make a similar light In yellow that can be ordered in via  Andre's KTM Klassiker in Austria.

Well its time to say....i think its finished (are they ever?)
Apart from sorting out the jetting,a nicer rear brake lever,kickstart lever and getting Rec rego on it...its a runner.
Proper decals will be done.(I like Bahnsy's one) Maybe a name change to RE175,a seat cover,etc,etc..maybe it isn't finished?  :-\

Thanks Michael,yeah a stand will be needed for sure in the bush.
I'll have to make something up as i don't have the bracket that bolts to the frame,unless anyone out there has one laying around they want to sell.

As far as i know NO, the Australian importer (CASSONS) Is not bringing the UFO vintage line into Australia. You can buy them from www.motoduro.co.uk or http://ktmklassiker.at or http://www.mdracingproducts.co.uk/ and all 3 will be a lot cheaper than what the light would be if it was available in Australia anyway.

YES they are available in White.

Since it was an RDO today I thought it was time to devirginise the RM175EF
I gave my mate a call this morning to see if i can tear up his 5 acre property in keysborough and do some sorting out.
The property is just a cow/sheep paddock so its pretty flat with just a few ruts and crap thrown in.
First thing i noticed about the bike is that nearly 30 years ago my PE175X "felt" fast.
Roll on 30 years to today,my recently departed 06 WR450F felt and was fast.

Getting on this RM175 and taking it on its first ride made me realise...this thing ain't no 450!!
Felt like someone put kryptonite under the seat....i was waiting for the power to hit....waiting,waiting.
It never hit,the power was so smooth and once i re-learnt how to ride a 2 stroke (as in scream the mother trucker!) it all came back to me...2 strokes are an absolute blast to ride!
I had a ball,i could tip the bike into corners and it would stay there,hold its line into and around the corner a slight feather of the clutch and fist full of revs and bang out,all in one motion.

My WR you would have to think about the corner,you chop the throttle,the front would dive from the engine braking and totally f@#k up my cornering to the point of having no idea what the front was going to do next...then as you "try" to lean the bike in,the top heaviness and engine braking to the point of slowing you down too much would make the bike want to fall down into the corner.
I have NEVER felt confortable on the WR since the day i've owned it and its been the cornering of that bike that i've hated all along.

Next thing....FULL FLOATER.....never ridden one until today.
2 words HOLY F@#K!
Now i know why the magazines raved on about them in the 80's.
Deep down i was a late 70's early 80's Yamaha YZ fan and Monocross diehard.
In the first 5 minutes of riding the bike and getting used to how well this thing corners and holds its line,i noticed the rear end stayed put under power out of the corner,then across a few deep tractor ruts with the throttle pegged.....a small kick in the butt,but it held its line beautifully and i could hit those ruts faster and faster at 60-80 KPH showing on my GPS strapped to the bars.

Nothing broke or fell off the bike.I still have to sort out the jetting,mainly a bottom-end fluffiness.
Started out with a 35 pilot then tried a 30 but thought the 35 felt better.I'll give a 40 a try next time and see what thats like,i'm not sure if its because of the 34mm flatslide.
Another thing that has to go is the throttle...my elbow nearly touches the front wheel with the amount of throttle turn! What were they thinking??
Might have to raid the Magura on my RM125T...short and sweet.
The only thing that stopped the bike today was FUEL ::) i ran out! Another flashback to riding 2 strokes,thirsty buggers!

Sorry for the long post but i thought i'd give you a run down on its first outing.
I had a ball and that was just in a paddock and it answered my own thoughts....i cannot ride 4 strokes properly/comfortably mainly because of their weight and height.
2 stroke enduro engines in a MX chassis or more to the point,light air cooled 2 strokes in a good chassis that don't tire you out are a blast! ;D ;D

Hey 308,
Don't appologise for the length of the post. Great info and good to hear the bike lived up to your expectations.

I have been following your progress and have just realised I have a spare '84  frame and a PE engine on the shelf…  Hmmmmm inspiration!

Those 175 motors like to rev very much like the cousin the RM 125  ;D  I can relate to what you are saying about comparing 4 bangers a 2 smokers two completely different style of cornering are required.

Thanks fellas glad you enjoyed it,i've had fun building it.
A few more tweaks here and there and the real test will be out in the bush,although signs of carpal tunnel in the last couple of years and a busted scaphoid wrist from 20+years keeps numbing my wrist and arm within 10 mins of riding in the bush,at least i can have the occasional play at Frankston MCC.
Enough of the violins playing in the background  ;D ;D

VMX42 if you have most of the parts...i say go ahead and do it.
I'm not sure of the differences in the rear of the PE175 cases of the floater PE's to the twin shock PE.
Leith and Luke would know.
Geez i'd love the 250-400 PE engine in this bike...it would rip but the 175 is great fun.
I still have my '85 frame if it all turned to shite.
One thing i really need is the bracket and side stand for the bike.The PE ones are too short plus i need the bracket...i'm sure other Suzuki bracket may fit,so i'll have to do a bit of searching.

As for the office chair...lol yeah i've run out of stands and milk crates.
Don't laugh but that stand has been a beauty in the shed as i can roll it everywhere and spin it around  ;D

Can't ride 4 strokes eh.... well there might be a reason the KTM300 and other 2 stroke enduros are still about. man this will turn into another f&^k 4 strokes session

Glad your project turned out great, back in the day there were a few 175/200 motors dropped into blown 125 frames being used as enduro bikes and now you can probably see why.

Post by: LWC82PE on May 25, 2010, 08:07:44 pm
The PE250 motor goes into a 82-84 PE175 frame. not too much cutting/welding is required and its fairly straight forward. In Theory a 400 motor could fit in the same frame as the bottom ends the same dimensionally at the mounts as the 250, but the overal extra bulk of the barrel/head would be too much i reckon as the 250 in the 175 already makes the carby a very tight squeeze plus i reckon there would be too much power for what is essentially a 1981 RM125 chassis. There was a dealer back in 83/84 that was actuallly putting PE250 motors into 83/84 175 frames and then selling them as 'their version' of what the 83/84 full floater PE250 could have been, so it can definitely be done.

Lol...Marc i never felt comfortable on the WR plus i'm an average rider and the tall top heaviness feel of the WR irritated me.Even a simple U turn on a tight single track caused problems because i'm about 5'7 with boots on,just leaning the bike over at the right point with no momentum the whole weight of the bike would feel like it just wants to fall over,and trying to pick up a 120kg+ bike on the side of a steep hill
was no fun anymore.
Weighing 80kgs with riding gear trying to pull 120kg + out of deep ruts and power that was only used/useful on firetrails made my mind up to sell it,plus i hardly used it this year because of shift work.
I'll miss the grunt of the 450 but no way will i miss the weight,i also think it made me a lazy rider.
I think last years KTM's sales of 2 strokes was 48% from memory.I've been tempted to try out the 300 but i think i'm over the holed radiators,water pump seal leaks wizbang stuff....first time out on the WR nearly cost me a radiator.The 9 years that i owned my old PE175X not a single thing broke out in the bush.
All my work mates swear by their 4 strokes because thats all they've owned,i grew up on 2 strokes and bought a 4 stroke because thats the "thing" to have these days.....well i'm not convinced anymore.

Leith thanks for that info...good to know.
Now how much bigger is the barrel and head finning of the 250 against the 175?
It already is a tight fit with the 175 head/barrel at the front downtube,so anything bigger
is going to need fin surgery,anyway i'm happy with the 175.

Luke...what are you upto ;) converting your 175 to a 250???

Michael no go for 3 bridges,damn work gets in the way all the time....who invented bloody money?

I took the bike out for another test today at my mates farm.
I swapped the magura throttle off the 125T and it was much better on the wrist.
I left the same pilot jet in but raised the needle 1 notch and took it for a spin and it sounded and ran too fat in the midrange.
Off with the airbox again and i lowered the needle 2 notches (1 above the middle) and took it out.
WOW....much much better and loving the power now with a greater hit from just above  1/4 all the way to nearly full throttle.
The off idle stumble is still there but i'll work on that again next time.I have an access hole in the airbox to get to the mixture screw but i forgot my allen key to get the airbox cover off.
Today was damp and slippery with alot of sheep crap flinging everywhere including in my eyes (goggles off)
I am finding it hard to fault this chassis so far,just waiting for it to step out and surprise me or spit me off.
This bike is making me look good even though i can't ride for shit and attacking some man made berms (excess dirt next to a dam) with more confidence than i thought i had  :D

The PE engine fitted with the modified RM100X? or 125T? pipe (in my stash of pipes)and the whatever it is muffler is working a treat with the 175 engine and the TM34 flatslide(once the off idle is sorted)
Almost an MXish powerband hit,not as violent but a great spread of power all the way to the top.
3 more lts of fuel today and I am loving this bike the more and more i ride it  ;D

Enquired about getting it rec rego'd for it this morning and i have everything they asked for.
Only need to connect the brake pedal switch(wiring already there) and fit a rh mirror...don't even need a stand :)
I'll have to book it in with Vic Roads and get the OK...then pay the dollars(as usual)
Thats it for today....love the bike more than i thought i would with more to get out of it.

You just need to put on a few kilos and a few inches mate and you can sling the 450 round. My own limited experience of both bikes is the WR feels a lot heavier to ride than the Suzook.

Update....
Haven't been doing much on the bike lately....picked up another monaro coupe from a work mate and thats kept me busy in the last couple or weeks but i have been doing dribs and drabs on the bike.
I took Doc's tip on chasing an RGV muffler for the bike as i hate loud bikes.
I scored 2 x RGV mufflers for $30.00 delivered so i was happy about that  ;D
These are off the early RGV's (muffler each side)so i had the choice of running either and put the RH one on,it just needed a mild tweek of the mount and i welded a bracket to the bottom for the side cover to mount to. For some reason i always thought they were aluminium...not so,just good ol' metal!
A little bit of weight in them(could also be clogged packing).
I haven't fired it up yet but i should hope it will quieter going by my old RGV's sound.
(http://i199.photobucket.com/albums/aa250/hjcoupe/RM175rgvpipe2JPG.jpg)

Sorted out the kick start fitment using the bottom knuckle off another k/start i had and modifying it to suit my lever,fits in nice under the pipe now and locks in too.
(http://i199.photobucket.com/albums/aa250/hjcoupe/RM175rgvpipe.jpg)

Another thing i have been doing is getting all the little bits ready for Rec rego...ie brake light switch,mirror and my CT90 horn...all good now.
Not sure if i have to run a rear chain guard. Anyone know????

Back and forth on the bike and Monaro..don't know if i'm coming or going these days.
After Doc kindly sending the TS fuel tap with the right angle and reserve to try out....it was no go as the tap was too long and hit the head fins.  :-\
After just about giving up and staying with the original tap being very close to the head,i took a punt
on buying a pit bike tap off ebay @ $7.00 ahh what the heck $13.00 all up.
(http://i199.photobucket.com/albums/aa250/hjcoupe/tap1.jpg)

Surprise surprise..same bolt pattern as the RM! :)
With the extra tube for reserve i just had to elongate the original single hole,the RM tank has a nice flat surface to modify it.
(http://i199.photobucket.com/albums/aa250/hjcoupe/tank1.jpg)

The pit bike tap outlet ID is even a tiny smidgen larger than the RM pea shooter taps.
Mounted to the tank...

Strange how all the major component interchanges happen so fast but all the fiddly stuff seems to take forever :P..or in some extreme cases (me)..never! ::) not referring to you Mario, your bike is looking great. So long as the part doesn't have 'MADE IN CHINA' in a blatantly obvious position then it's all good if it does the job. And those RGV mufflers, beaut aren't they! Whilst a little heavy they are stupendously thrifty shopping at around $15 a serve 8) matter of fact I've just fitted one to project 118..it fits so well whether or not it functions correctly doesn't really matter a zac ::) even pre-scuffed in the right spot to give the illusion it's been fitted for ages so obviously it must work :D

Back on the RM175 as i'm still waiting on the rod kit for the RM125T.
After riding this bike for a little while,i noticed that the front brake wasn't that powerful with the single piston caliper.
So i found a twin piston front caliper off an 93 RM250 for $30.00US delivered to see if i could adapt this to my 85 forks.
Top caliper bolt lined up but the bottom bolt was about 15mm higher than my bottom caliper mount hole.
It also sat 5mm further inboard (which was good)as i could make up a 5mm thick bracket for the new caliper to mount on and then bolt up to my forks.
All centred up on the disc and I had to turn the banjo fitting around to clear the bleeder.
An hour of my time and a spare bit of 6061 T6 ali plate for extra strength and all done and fitted...and pulls up better!

Still haven't got off my arse to get it rec rego'd  :P truth be told is that i have 2 car rego's and 1 bike rego in successive months over xmas and Vic Roads get enuff love out of me ;D
I took the bike out to my mates farm again and i absolutely love this bike.
I didn't even bother trying to sort out the very slight bottom to midrange jetting hitch and just kept on riding it to death.
This is what the PE's should have been Mr Suzuki  >:(
I finally got around to fitting the 3 month old seat cover after my PE cover arrived last week and wanted to spruce it up a bit,although the 125 bit eats me inside  :D
(http://i199.photobucket.com/albums/aa250/hjcoupe/blaster12.jpg)

Update.....after getting sick of looking at the wanky bottle i had on the left side of the bike,i decided to make a small tank to fit in the same spot where the radiator was.
It was a bit of a pain with the angles but i got there and just have to tap in the fitting on the bottom and a breather at the top.
I'll put a tee piece into the line and all should be good to go.
I haven't measured how much extra fuel it holds yet but anythings better than the 6 odd litre tank.

OK 2.2 extra litres to play with now and fittings are in...job done!

Out of shear boredome i've never been happy with the light blue frame so i gave it a rattle can job over the week end and loctited all the nuts and bolts that i needed to while it was apart.
I finished the alloy tank with a tap but haven't decided if i'll tee off into the other hose or tap into the  front side off the fuel tank tap.The pitbike tap has a blanked hole on the frontside and all i have to make is a barb and press that in.
I also put heat wrapping around the expansion chamber and covered it with insulation tape (i might paint it black)the reason i did that was the bike was actually louder at the chamber than the back of the muffler,and being an modded RM125T pipe it sounded very tinny.
Still haven't rec-rego'd it....but its getting close ;D
cheers....Mario
