RMX

[wmc83]

My new project for the next few months hopefully ready for next years riding season a pre90 RMX250 or is that a RMX RMX250 anyway not touching that subject with a 60 foot pole! Anyway this is going to replace my WR450 as a trailrider with a view to racing pre90    I'm more into early 80s bikes but I'm not to keen on going bush with drum brakes etc and these things are alot easyer to get parts for so anyway here it is.


Looks better than it is (as is often the case) cases both damaged, crank stuffed, top end rooted and past the sleaves last oversize and generally rebuilt by someone who shouldn't.



Off to the powdercoater tommrow hopfully I can get a close match for Suzuki blue



This blew the budget a bit but I'm not interested in pushing it home from a bush ride!

[wmc83]

I don't know why anyone would bother making there own footpegs but hats off to this guy! I just stared in disbelief when I picked up this parts bike unable to form the word WHY?



And aparently bat shit did this      Bats with acid for blood!



Sorry for the shit photo quality I'll use the camera next time.

[frostype400]

cool I am putting a disc ts250x front end on my pe400 project bike that I will use as a bush bike so I can stop.

bugger the forks being a bit ratty and foot pegs why bother if you are downgrading on stock.

Do yourself a massive favour and get a PWK 36/38 carby. The PJ's are shit compared to it. Watch for the woodruff key shearing off and get a VForce for it. Up the compression and you will wonder why you ever bothered with a 450F. If you want to be really smart find some post 03 RM 250 suspension.

Often wondered just how good one would be if you threw away the shitter 250F engine from a RMZ and chucked a tuned RMX in the frame. Like this

Hey Lozza will a later model shock work in my bike without revalving etc I was just going to service the old one any get a spring rate to suit my weight and yes I got a PWK 38 off a 99 cr250 so I'll be looking for jeting advice later!

[dalesween]

Bat shit is more acidy than you would ever believe.

cheers dale.

[frostype400]

How do you know Dale have you tasted some.

[Lozza]

Bat shit is more acidy than you would ever believe.

cheers dale.

Hey don't start me on those  c**ts, in the space of a hour or so their shit ate through the duco on my car on a hot day. Flying rats they are.


Realy any 250 shock is going to be close, apparently after 03 japper OEM stuff got pretty good. Just measure your eye to eye lenght/eye to yoke , spring diameter and if you need a remote reservior or can handle an attached one. You will be pretty close.

[wmc83]

I'm going to move this on to the new classic dirtbike forum and see how it goes

[oldfart]

If you have installed after market flange nuts, make sure they have flat faces .......otherwise they will work there way loose        Cylinder and head

thats a cr500 motor in that rmz lozza

[firko]

hats a cr500 motor in that rmz lozza

I was thinking that myself but was too scared to say something in case I was wrong. Whatever engine's in the bloody thing, it looks like a badly decorated Christmas tree.

I know that's why the put all the aftermarket ignition and clutch covers on it.

[wmc83]

Been able to give things a serious nudge over crissy holidays and it's all coming together nicely IMHO you wouldn't think it was 22 years old to look at it.






These disk brake wheels are piss easy to build compared to drums no redrilling rims and spokes all the same length Too easy total cost under $400

[wmc83]

I had to have a bit of a guess at jetting as I swapped the carb from a 38mm TMX to a 38mm PWK it starts first or second kick when warm and idles fine but it seems a bit smokey and fells rich on the pilot also the idle screw is almost screwed in all the way which seems strange but this is my first go at 2t jetting so any input is welcome my carb specs are as follows
48 pilot
175 main
55 slide
1370 neadle 3rd clip
as far as I can tell a 70 slide is the way to go but I'll see how goes when I can ride it.

Very nice WMC

I was getting into to a similar thing with my TSX250 keeping it with the pre'85 regs but I need (still hunting) another frame to modify so I can fit a smaller RM125E tank instead of the fairly large steel stocker. I wish to keep the stock frame intact just incase it goes back to original one day



not sure if you have any literature on the RMX but here's the Aug '89 Trail and Track test where it was highly regarded.

WMC do a search on thumpertalk.com in the offroad-suzuki-2stroke-section.
There are a few blokes that have done the PK conversion that may be able to steer you in the right direction and love their RMX's.
I have come so close a few times in wanting to get an RMX250 and still do have a look,but i struggle to ride 1 bike let alone 3 or so on the go.
Its never off my "want" list though
Keep the pics coming.
cheers..Mario

[wmc83]

Thanks Doc
That TS is coming along nicely a mate had one years ago and loved it. Pre85 and road legal too I should have considered one of those as well what are they like for parts?  and ta Mario i've been all over the net looking for jetting specs for PWKs and they vary big time so i've sort of split the difference! there good bikes but watch out for dogey power valves and frame rot if you get one the good thing about them is that it's tamed rm250 so you can set them up to be as mild or wild as you want

[DR]

83, you can pickup the TSX's dirt cheap, $100 for a basketcase, $200-$300 for real roughies that were running last time they wuz riddin , about 600 to 1000 for reasonable to good running riders with no reg and anything over that price would want to be pretty decent and/or registered with all the bells and whistles in working condition Frames break above the swingarm pivot which isn't a good thing. This is easily sorted with a little strengthening but otherwise you don't seem to hear of many problems with them.

Here's a frame if you can get it home:

[DR]

Thanks Zorros. I actually have a frame identical to that one because I didn't realize there were 2 types the one I need is the semi double cradle for the centre port engine appears from the blackened look and extra lumps the egay frame may also have been a bit snappy not unusual

[holeshot buddy]

hey doc if you need a 1984 rm125 tank i have one
you can have it
also have a ts250 watercooled under house 95%

[DR]

I have a 125E tank courtesy of Bahnzy but thanks anyway Rusty

[frostype400]

I am after a ts250x front end but mainly the front wheel would get me out of trouble though.

That rmx is looking sweet I saw one at bonnie doon last week thought about asking if it was for sale I want the gt80 next door though.
