Title: My New Project
Post by: DJRacing on October 27, 2007, 04:37:19 pm: My new project is a YZ125B that I'm slowly putting together. The frame for this bike use to have a sidecar on it I think, as there were bits and pieces welded all over it on one side, even a grab rail at the back. So out came the grinder with a cutting wheel. Anyway all you 'old YZ125' fans might like to see the start of a project that will hopefully look like an OW11.

The YZ125 tank and straps. The tank straps a new.

The back of the seat base need to be cut shorter and the over-hang re-plastic welded back on.

The project in its entirety..... a YZ125B as I see it.

Title: Re: My New Project
Post by: DJRacing on October 27, 2007, 05:26:14 pm: So far I have moved the mounting points on the tank and made the back underside of the tank wider and deeper and the mounting points for the tank on the frame lower and further back. Made brackets for the tank straps. Fitted new bearings and races for the steering and new bearing and bushes for the swingarm. The tank straps I made as will. The rear monoshock has been re-built and the travel shortened. The next step is to make the loop at the rear of the frame and brackets of the rear mudguard. I have to get a new seat foam and cut and mold it to fit the bike (with the correct look), then a new seat cover. I am in the process of building a motor (checking gearbox parts and trying to sort out clutches etc etc).

Post by: firko on October 27, 2007, 06:13:42 pm: Cool project DJ. There's a lot of satisfaction to be found in building a bike up frrom a total dunger. To me, projects like this are what our movement is all about. Keep us updated on the progress matey.

Title: Re: My New Project
Post by: vandy010 on October 27, 2007, 06:53:49 pm: a real nice piece of work DJ.
one question though, i thought a 'B' model was still a twin shock same as the 'A' but in yellow. this looks to me like a 'C' with the 'A/B' style tank.
i don't care about correctness as i really like what i see. just curious.
juice me some more, 5 speed or 6?
Title: Re: My New Project
Post by: DJRacing on October 27, 2007, 07:39:55 pm: Ok Vandy, my reckoning on the matter is that the 'B' model 125 should be like its bigger brothers the YZ250B and 360B which were monoshocked bikes with 'A' style tanks and tank straps, so I am building my own monoshocked 125 with the "A-B" tank and straps and a YZ250B looking seat. As for the front forks, they are the same as the YZ250B except the legs arent as nicely machined. I will be machinning the lower legs to give it a more werkys look. The motor for this project is turning out to be a little more difficult than I first thought. Originally I was going to use a set of '74 MX125A cases but have found that the gear box I was going to use was good but the selector drum is different at one end. I can fit a 6 speed box into the cases but cant select a gear ;) so I'm going with 'C' cases and gearbox. I want to put an 'A' barrel and head on her, but first I have to check the reed block intake. I want to machine the intake out to fit a bigger reed block and port the barrel similar to a 'C' 125 or even an 'X'. It will depend on the transfer ports. The beauty of this project is that DT-MX and YZ stuff are all very similar around that period of time so it will be a bit of mix and match. I was looking at using mud-catcher rims, but I prefer the 'C' model rims so thats what will be going on for the wheels.

the 125 yamaha should'v built in 75.
pm on the way.

Post by: DJRacing on October 28, 2007, 07:28:19 am: Yeah you got it Vandy- the real YZ125B ;D
Title: Re: My New Project
Post by: firko on October 28, 2007, 08:04:10 am: DJ...I actually built a twin shocked version of what you are building back in the early 90's. I too tried to fit the 6 speed to the mx125a cases but had some sort of problem that I can't remember now. I ended up using the complete X model engine, I made a pipe out of a combination of the X and A items that looked like it was factory, even though they originally ran up oposite sides of the bike. I used 34mm MX250 forks and the X model wheels. Topped off with alloy bodied Konis, Webco head and a yellow plastic YZa tank (I think it was the larger 250/350 version) and straps.
Right from day one the bike was ilegal due to the post 1975 engine but with the Webco head the engine was disguised engough for it not to be noticed. I hadn't set out to build a cheater bike as I was actually building a legal 125 engine using a rare Noguchi top end and DG or FMF pipe (I think) to be fitted once it was finished. Unfortunately other projects got in the way and the Noguchi engine was never finished and the lot sold to a bloke on the condition that he didn't race the bike with the 6 speed engine. I only ever saw the bike once more before he sold it on to someone in the bush for short circuit racing.
I often wonder what ever happened to the Noguchi engine. Looking back I had a great time building the bike but soon realised that I was too big for the 125 tiddlers. My only regret is that I wrecked a pristine X model 125 and an equally nice MX125a to create the bike. X models were worth diddley shit back then and MX125a's were and still are not taken very seriously. Your project is taking the concept to another level. You're not destroying two perfectly good bikes to achieve the result, in fact you are doing the opposite by rejuvenating a pile of shit from a fate worse than death that will hopefully result in a cool little bike.
Title: Re: My New Project
Post by: DJRacing on October 28, 2007, 09:21:12 am: Firko, That was my orginal plan, to build a twinshocker, but I cant seem to bring myself to build a twinshock YZ ;) ;D(dont get me wrong I love the "A" models but its the mono's that are my Elle McFergusson). So the plan evolved into using a YZ125C frame, which I didnt have. But I knew where one was that had so much crap welded on to it that I could actually bring myself to put a cutting wheel to it.
I have a real problem with cutting and hacking at orginal parts (because someone may need them one day, p.s. you HL boys lookout >:( ;)) so thats why I'm going to go with the "C" cases. I wanted to put "A" sidecovers on as will but with the exhaust exiting the other side it would mean cutting up the "C" pipe or cutting up the "A" sidecover and molding up where the exhaust pipe would exit. I felt neither is appropriate. The motor that I will make up is from spares that I have acquired over the years that are just sitting around doing nothing. So far the only 2 parts I have had to alter to the point of no return are the seat and tank. As for the frame, it could go back to a "C" but then again I already have a white and a yellow "C" so what better use for a frame that had a bottom end of an IT175 in it and half a scap-yard weld to it. No parts on this bike will be newer than '75 but I assume that over there (Oz) it wouldnt be legal to race in pre75, but over here because we dont normally run pre78, flow on bikes with under-slung axles and the like are allowed to race pre75.
Firko did you take any photos of the bike??
At the moment I race a YZ125X in pre75, but I personelly feel that it is a cheater bike(not that I win on it, TMB kicks my arse), and the friendly (standing at the bar drinking) ribbing that I get from the boys about the YZ125X is all good but hopefully this bike will help ;D.
I have been working on it now for about 2 months and by christmas I hope Santa can drop it down my chimney,(I will leave him a bottle of 'old bushmills' if he does ;D
I am looking at painting the tank in white with Noguchi stickers.
Ahhh, the old 'a fate worse, than a fate worse than death' in the immortal words of Blackadder, a painter with a cutting wheel on a grinder... ;D

seller is 211suzuki up in QLD. the name rings a bell and i think he may be or has been a member of this forum.

could this have been any use to you? or not the right period? or wont fit? not hard to find or make a raditator for it.

Title: Re: My New Project
Post by: Nathan S on October 28, 2007, 08:21:00 pm: FWIW, the problems with trying to fit a 6-speed box into a set of 5-speed cases, are:
The shafts that the shift forks slide on are smaller diameters (could machine up some bushes, IIRC);
The diameter of the gearbox input shaft is smaller (6303 vs 6304 bearing, if my sleep deprived brain serves me)(this can be solved by using the correct bearing and clutch);
The diameter of the shift drum is a different diameter (larger on the 6-speed?).

The last one is what stopped me doing it. I'd planned on fitting YZ125E internals into my DT125A cases, with 6th gear locked out (by brazing up the appropriate part of the shift drum), but it got to the point where things were beyond my limited machining skills and my sense of mechanical adventure.
FWIW, a 125C gearbox is totally different to a 125E box, but still has the same differences compared to the 5-speed.

Anyhow, cool project DJR.
In your position, I'd just race a 125C, but what you're doing is far more interesting. :)
Title: Re: My New Project
Post by: DJRacing on October 28, 2007, 09:17:16 pm: C'mom now Nathan, just race a "C" ??? And I was building up this bike for you to race when ya finally get over here ;D
Yeah I found out about the internals of the MX125A cases Nathan, ya could've told me earlier ;D ;), but hey it was a good experiment to try, but to much work/(cost) to be viable.
By the way, what is (FWIW)

Post by: DJRacing on November 01, 2007, 06:27:51 pm: Have just made and welded the rear loop on to the frame as will as sidecover retainers and rear mudguard brackets. We had to bend, bash and generally beat it into place(as ya do). The frame is getting close to being stripped and off to the powercoaters.

Post by: DJRacing on November 05, 2007, 03:54:28 pm: Still working on the project guys, I am working on the tank. It has been painted and have put the graphics on. The rest of the work will carry on over the next couple of days. The red at either end of the tank has to be sprayed on and then a clear coat. But I like it so far. ;D. I hope to maybe ride this bike at CD-5, so if I keep working on it and posting photos you will know the progress and if I'm going to be even close to having it ready for CD-5 ;D

Post by: yzhilly on November 07, 2007, 12:00:43 pm: Coming along nicely DJ, But are you hoping for CD5 to be in NZ or are you goin to have too fit it in a suitcase and reassemble it ?.If it's to hard to get bikes over here for it I,m sure we can accomadate you with appropriate bikes i will have a selection of YZ,s if you need a ride .
Title: Re: My New Project
Post by: DJRacing on November 07, 2007, 04:03:33 pm: Thanks for the offer Hilly, Myself and TMB hope to take a couple of bikes over and maybe if we can get accomodation/storage for them we will leave them over there so we can come back and maybe ride the Nats in Tassie or a meeting around Brissie/Sydney/Melbourne/Canberra. Hopefully we can have bikes over there for maybe 1 or 2 years and then we get to do a few races meetings/CD's. And that way the cost of getting them over becomes less and less the more times we go over to ride ;D.
Title: Re: My New Project
Post by: Nathan S on November 08, 2007, 12:36:10 pm: TMB needs to bring his 125A over. It can live at my place and I can save him the cost of return freight.
Title: Re: My New Project
Post by: DJRacing on November 08, 2007, 03:49:23 pm: Nathan, I have TMB YZ125A at my place, so some how I dont think it will be going to your place ;D ;D. its going to be hard enough for him to get it away from here.

Anyway the tank for the bike is now finished and I think the end result is looking good.

Title: Re: My New Project
Post by: DJRacing on November 09, 2007, 02:25:15 pm: Thanks for the auction posting cyclegod but I already have a NOS set of cannisters with the rubber protectors on them. But I would say a few people will want them as the rubbers always seem to get lost or misplaced.

Boney I didnt paint the tank, as their is a local guy here who is into VMX and he is a car painter so I dropped it off to him after cleaning, sanding, preping it so he just had to spray a coat of white. Then I got the decals made up by another local VMXer who is in the sign business and then back to the spray painters for the red and clear coats. The next job for me is to strip the frame down and take it to the powdercoaters. While they are doing their thing I will order a seat foam from MXM in Oz and get to work shaping, moulding that to the correct shape and then I will have to get a seat cover made. If I had the money I would love to replace all the bolts/axles etc with titanium, but dreams are free, so I will just have to wait until I win lotto. Then its the zincing. I havnt got the wheels for the bike yet, so I'm not sure if I will have to de-lace them and get them re-zinc, but knowing how things work I most probably will have to do that(I will be getting all the bits and pieces re-zinc . One of the jobs I will be doing soon is the lower fork legs. I want to bead blast, and machine them down to give them some shape and a different look to the norm. I was thinking about oval aluminium sidecovers but I think (for dust purposes) the original ones would be better.
Title: Re: My New Project
Post by: DJRacing on November 20, 2007, 08:37:09 pm: I ordered a seat foam from Bultaco Parts over in Aus last week and it arrived yesterday so I have been buzy cutting and shaping it to fit the bike. I had to cut the front and back off and then slice a section off the back and then re-glue the little back piece that covers the seat base. The top of the seat foam (where ya plant ya ass) has been sliced off as will to lower the high of the seat and then I had to sand and shape the foam to how I want it to look on the bike. I hope its going to look ok, but its a bit hard to know without the seat cover on. I will be getting a cover made up tomorrow and hopefully by the end of the week I will have a new looking seat for the bike

Post by: DJRacing on November 23, 2007, 04:40:57 pm: After having to cut and shape a seat foam, the seat was sent to a guy to make a cover and put the cover on. I have just finished the lettering at the back of the seat. A new set of foot pegs are now on the bike. Good big sharp pegs, it will be like riding a modern bike ;D. The pegs are from a pit bike.

i must say i am enjoying reading the progress and checking out the progress pics.

i'm in the middle of a rebuild on my CR500 and enjoying that at present. i had to fabricate some brackets
(some weird shapes and angles) as the 86' frame is slightly different to the 85' model. but nothing like the work that you are putting in
Title: Re: My New Project
Post by: DJRacing on November 23, 2007, 05:33:45 pm: The foot pegs I got of Trade Me for $50 and had to cut the mounting lug, do a bit of grinding, filing and form the springs to fit. The next job is to make a rear brake peddle out of ali to give it a werkys kind of look. I'm still going through motor parts and waiting on a few bits and pieces to arrive from overseas. Hopefully you guys will get to see in in the flesh at CD5 if I have it up and running reliably, and ya can pick holes in it then ;D , but as always in vmx, nothing is finished, its always work in progress ;D
Title: Re: My New Project
Post by: DJRacing on December 13, 2007, 06:17:40 pm: The project is coming along, I took the frame into the powdercoaters today and they bead-blasted it and I knew of a couple of places that needed welding so it was a mad dash at lunch to get the frame then go to my welder to glue it back together and then back to the powdercoaters to get its primer coat on after lunch. All going well I might have a frame to work with in the weekend. I'll post up some pictures of the frame so all the non believers in powdercoating can have a look and voice their oppinion on why it shouldnt be done ;).

(http://i45.photobucket.com/albums/f65/djracingyz/YZ125B090.jpg)

In the mean time I have been working on a couple of bits and pieces for the bike. I made a new rear brake pedal and have bought new uni-filters for it and new levers (cheapies). I am cleaning parts and getting them ready to go to my electro platers. I have to strip (de-lace) the wheels and all that, so its a buzy time and I dont like to rush this kind of work but if I dont pull my finger out of my ass the bike wont be ready for CD-5. What tyres do you guy recommend for Raymond Terrace?

i used to ride there years ago {20yrs ago!} and it was about the same as concrete but not quite as soft {no bull!} but read the CD5 bizzo again and you'll read it's being re-surfaced so tyre choice is anyones guess. track is a nice layout though so i for one am looking forward to getting back to "the terrace" again.
lookin good DJ!

Post by: vandy010 on December 14, 2007, 10:53:40 am: just had another thought DJ,
i'll be taking a spare back wheel for my little MX for the flat track,, it should bolt straight into this weapon of yours should you want a lend.
428 chain,47tooth,michelin.
flat trackin Noguchi...
Title: Re: My New Project
Post by: DJRacing on December 14, 2007, 02:43:31 pm: Vandy I know nothing about flat-tracking but I would love to give it a go. The only problem is I will probably run a 520 chain on this bike. Thanks for the heads up on the tyre choices. Concrete you say, bugger I hate the hard stuff, give me mud anyday.

Over the xmas break I will be cleaning the plastics and painting the hubs and triples.

Bonehead, I took your advice and bought a new coil ;D. I have all new bearings and oil seals for the wheels and new gaskets and oil seals for the motor.
The zincing is just about ready to send away but with it being christmas there isnt much point as Im sure they will be shut over the break so that will have to wait until next year. But there is plenty of work to carry on with over xmas.

Post by: cyclegod on December 22, 2007, 02:43:09 pm: Your about the same stage as me with my MX250 project EXCEPT I have my zinc plating done already. A useful tip for future powder coating is to, after sand blasting, take some old bolts and fit them into your threads till they are flush with other side (not protruding) then after coating just unscrew then and you have nice clead threads ;D .
Title: Re: My New Project
Post by: DJRacing on December 22, 2007, 05:27:03 pm: Yeah I hear ya cyclegod ;D Althought I like re-cutting the threads and it leaves a nice clean transition from powercoat to clean thread. Have you done anything to your motor, suspension or plastics? I havnt touched the forks and I know they are leaking and the rear shock needs to be pulled down and looked at because its as hard as a brick and the motor for this bike hasnt been pulled apart although I do know that the rod is locked up. So I still have alot to do, and that isnt including test riding it. ;D

Do you like trying to extract broken taps? ??? Just a friendly bit of advice based on experience with powder-coated threads, until I started fitting screws flush, where I used to work, taps as large as 8mm were snapping off in the powder c0ated threads. Its easy to 're-cut' a thread before blasting and much nicer just removing the powdered bolts after because a tap never quite gets ALL the powdercoat out.

I'm using these shocks on my MX racer...only $150.00 US ;D

Post by: DJRacing on December 22, 2007, 09:43:22 pm: I havnt broken a tap in a thread but I have made a tap so blunt that it was completely knacked. After that experience I when out and bought a good quality 6mm tap and have never had a problem since. And the bonus of tapping a thread after powercoating is that it is like new again ;) ;) ;D. So I take it that you dont have to re-build your shocks then? When are you looking at having the MX up and running??
Title: Re: My New Project
Post by: cyclegod on December 22, 2007, 09:51:56 pm: End of January I hope, but you know how it goes, everythings going to plan until you need one small part, that just you can't do without,
can't get OEM anymore, none on eBay and when you do find one the bastard sends it by surface mail even after you asked for and paid for Airmail >:(

All things being equal, end of January is realistic (unless my new PVL ignition doesn't arrive, ah well points on standby)
I'll try and post a first run video on youtube when she's ready.

Here's a pic of the tank I got off eBay.

I would be looking at 4 to 5 days hard yakka driving there AND driving back, plus I would have to rent a small truck to get my bikes over there (1MX plus 2-3 TM's), plus food,fuel, & lodging. Best estimate puts that at about $4000 which is too pricey for me, even freighting my bikes there, flying over (6 Hrs) and still renting a vehicle is too much. Mind you it would also be ridiculous to host an event like that here in W.A, never mind trying to get to the Nationals too!!!!!!!!!

Stop ya whinging God. The MX is more important than you. Just freight the MX and we'll get someone to display it for you and do a few 'demonstration' laps so the plebes can get to see and appreciate such fine machinery. ;D

Post by: DJRacing on December 23, 2007, 07:55:28 am: Cyclegod at least your in the same country. I on the other hand have to get a passport, drive to an international airport (argue with airport officals that my bike is hand luggage) fly out of my country to Sydney, find accomdation, find a place where I can re-build the bike, rent a camper van, get the women away from the shopping, drive from Sydney to Newcastle, find the women in the shopping area of Newcastle, rent a small car for them so they can still get around while us guys are "classic dirting" and then drive from Raymond Terrace at the end of CD-5. I have to once again find the women (but this time they will have a car) shopping in Newcastle. Drive from Newcastle to Brisbane. By the time we get there the women will be on withdrawals from shopping and have to get a fix again. I will have to get rid of the camper van, store the bikes, and then get the women folk away from the shops in Brisbane. About this time I will realise that TMBill is still at Kamp Kevlar drinking magiritas with Firko................ ;D ;D ;D.

Cyclegod, just get yourself to CD-5, bring pictures of all your bikes and ya never know, someone may loan ya a bike to have a blast on.

Post by: DJRacing on December 23, 2007, 06:52:08 pm: The triples, hubs, brake plates and throttle housing have been primed and recieved several coats of VHT black oxide. I warmed the spray can up before I used it and I dont bake the VHT as I like to let it cure for about a week in the coldest room in the house so it keeps its satin look.The bottom triple clamp is full gloss black and that has been given several coats as will. The airbox has been stripped, cleaned and put back together with black silacon in the rubber joiner. All the parts that need to be zinced are cleaned and ready to go. I have started to pull the shock apart(will as far as I can go) and I think it needs some serious work as I cant move the shalf at all. I will pull the fork legs apart tomorrow and bolt the airbox into the frame.

Post by: DJRacing on January 12, 2008, 11:44:06 am: I hope to Firko, I have been making inquires about air freight and everything else that goes along with it. I hope to get the bike together, ride it here to make sure she runs sweet and everything is working as it should do, and then strip her down again(the bike, not Karen ;D) give it its final spruce up and pack it in a box about 1m X 1m X 600mm and send her on over.
Its been a very interesting project considering I got only had it in my head about 8 months ago and didnt have a frame, tank, wheels, airbox, seat and allot of smaller parts. But with help from friends and what I had in my own stock pile the idea has started to take shape.
The reason for doing this thread is that if I do get it to CD-5 all the people who have followed this thread will get to see it in the flesh. (Photos Lie). At the end I will try to make up a list of new parts, remade parts, restored parts and the cost of everything(now I will have to cover Karens eyes ;D) so the members who have kept following know what it has taken me to get a hopefully good little vmx bike. Of course this ride is a rider, so there are a few little things that I havnt spent much time on but they will be functional if not pretty.

i was going to do something similar and post pics of my CR rebuild progress but i
now think it is 2nd rate compared to your project and would be of little interest to the forum as its just a standard bike not a project bike.
Title: Re: My New Project
Post by: DJRacing on January 12, 2008, 12:10:09 pm: No such thing as just a standard bike Hoony. At least with a project bike I can modify/cheat, but with an original bike I feel the restore is harder. I would like to see you post pictures of the build up Hoony as I live over here and cant get to see the bikes, resto's, and projects that you guys get to do. I think all forms of projects are worthy of having their story told, because of the problems we all face when rebuilding something which can help the next guy. Or it may even incourage others to do up their bikes. It doesnt matter what the end result looks like because some guys dont want/like the "off the show room look" and others like the bling look, compared to the old patina. Some just want a very reliable properly functioning bike. I think thats one of the great things about VMX is that its so deverse, weather you want to spent mega $$$$ or ride her as she comes, its all good.

Title: Re: My New Project
Post by: DJRacing on January 12, 2008, 08:37:33 pm: Ok guys, the reason the resto is happening in the lounge is because the garage is full and so is the spare bedroom, so the lounge it is ;D ;D ;D I'm lucky Karen is very understanding, she realises that I'm a good boy and say my daily prayers ;) ;D ;D. And lets face facts here anyway, when she wants to do some sewing I dont make her go out to the garage :o ;D ;D

I have been looking around for a set of handlebars but havnt liked any, althought not having the bike built up hasnt helped getting the right size bars, but I have ordered a set so I hope they are right(if not they will get used on another bike).
Its surprizing how the little things still need tweaking, like brake pedal springs and a few other bits but she should be a rolling chassis by Wednesday/Thursday.

Title: Re: My New Project
Post by: DJRacing on January 13, 2008, 03:00:14 pm: Its home made out of 6mm marine ali and I have a brake snake for it because it will bend and I dont know how long it will last but if it gets me through the year I will be happy. I have just been working on the brake pedal, because of the hole for the pin to hold the brake rod on was a guess, there is extra lenght there so instead of cutting it off I thought a good idea would be to drill 2 extra holes so I have adjustable braking leverage. Yamaha are notorious for having vicious rear brakes and if this helps then all is good but if not, it was worth a shot.

The bike that I am build is probably closer looking to the OW11 back in 1973, but I thought it would be a nice twist to call it a Noguchi and over time buy genuine Noguchi parts for it, like a barrel and head.

Title: Re: My New Project
Post by: DJRacing on January 15, 2008, 06:30:20 pm: A brake snake is a piece of wire that holds the brake pedal to the frame. You can make one out of an old clutch cable wire. Cut the nipple off at the handle end of the cable and pull out the wire. Drill a small hole through your brake pedal and thread the wire through so the nipple at the other end holds the brake pedal. Slip a piece of old carb hose(about 10mm long) onto the wire hard up against the brake pedal. Then get an electrical joiner(the type that has the two grub screws in it) and thread that on to the wire. Then cut another piece of the carb hose long enough to go around the frame, thread that onto the wire. Poke the end of the cable wire back through the electrical joiner and pull it tight enough so that the brake still works and you have a brake snake. It is there to stop the brake pedal bending outwards away from the bike.
Failing that, if you dont want to make one go to your local shop and ask for a brake snake and pay $15 ;D

it's a trivial thing i know but those std front guards look super average in my opinion. no offense mate. as an option if your interested, i just lashed out and got me a white YZ250/360a/b front guard from AMS in the states, she looks soo sweet, nice shiny white and light. i reckon it'd just set off the look of your bike to the next level.
just me being fussy and not meant to offend.
cheers...
Title: Re: My New Project
Post by: DJRacing on January 15, 2008, 08:22:38 pm: No offence taken Vandy ;) I dont shy away from critizism, its all good and if it helps, all the better then. But my thoughts on the guards are that if they are genuine/original then they are the ones to use. I have cleaned them up to the point were I dont mind them getting scatched when racing, and after all they are 32yrs old now. Dont forget it is a race bike not a show bike and instead of spending money on after-market guards I think I'm better off to spend it on the motor and running gear. I am trying to keep to a budget ;) but I just havnt figured out what the budget is ;) ;D.

Vandy, is the offer of a rear wheel with a dirttrack tyre still open?? I am going with a 482 chain.
Title: Re: My New Project
Post by: vandy010 on January 15, 2008, 09:42:34 pm: the back wheel offer is most definately yes!
my flat track wheel is the yz/c with a dished 47tooth 428. it's got new bearings and runs a slightly used michelin trials tyre which is supposedly the good stuff for flat track. sprocket is new so shouldn't do your chain any harm and with your spacers/brake plate it should bolt straight up.
my mate and i plan to get there friday arvo so we should have heaps of time.
keep up the good work champ...

EDIT!
i've just read the vmx site's CD5 blurb and it says the flat track will be unavailable.

Post by: DJRacing on January 21, 2008, 07:30:41 pm: Yeah I have been watching that auction for a few days. The tank looks like it was just made yesterday, someone must have looked after it very well for over 30 years.
Title: Re: My New Project
Post by: DJRacing on January 26, 2008, 07:26:43 am: I have made up new cables for the bike, and the rear brake rod is fitted also. The brake pedal seems to work with the adjustable leverage, althought until I actually ride the bike I will have no idea if it works properly. The next thing to make are footpeg springs. I have bought a spring that the pin fits threw so I just have to bend the ends to how I need them to hold the pegs down.
I have bead blasted the engine so after the barrel get a rebore and hone I can paint the motor. One of the cases needs a small repair to the rear engine mount, once that has been done its painting the motor and then assembling it. I have new gaskets, o-rings, oil seals, con rod kit, piston kit and all new bearings for the motor.
Basically the bike is now a rolling chassis except for a front number board, which I thing I will look at 'multi mounts au' front number board. I still believe my rear shock is to hard so I will keep working on that.
My pipe for the bike has a few small dings in it so I will heat it up and blow them out, and paint the pipe.
The gearing will be interesting as I'm running a gold DID race chain(428) 45 tooth rear (47 standard) but I have a selection of front spockets (12-13-14-15-16) so I should be able to find something that works.
I'm starting to get excited about having a ride on the bike but it will still probably be a few weeks away yet as I like to let the paint cure for at least a week.

Title: Re: My New Project
Post by: DJRacing on January 26, 2008, 09:40:15 am: Evo550 yeah I would like that barrel and I have a webco head that would go striaght on top. The porting looks very different with the direct port being round(not a cut away) and the bottom intake port direct into the crankcases is very intertesting. I have a barrel here that has a cutaway intake port but have never used it. In standard form the yz barrels dont have that cutaway. I shall watch the auction with interest and you see what it goes for. I have bidded on a couple over the last 6 months but as yet still dont have one. Maybe this time ;) ;D
Title: Re: My New Project
Post by: Hoony on February 01, 2008, 06:25:28 pm: must be time for an update DJ?
Title: Re: My New Project
Post by: DJRacing on February 01, 2008, 09:49:11 pm: I have been waiting on a couple of parts for the motor and the cases to be repaired. I found out today that one of the bearings I needed is NLA but after a bit of searching we found one over in your 'great southern land' and for the price of 3 vegemite sandwiches the bearing should have been shipped out today. I picked up the cases after work today as will as the crank with a new rod and big end fitted. The barrel has just been bored and honed for the new piston so all is looking good. I have started painting the motor but I am devastated, the paint I usually use has been discontinued. My beloved VHT case paint is now no more so I am trying a different spray can so its a bit experimental at the moment. So far I have applied 3 coats and I think I have it at about the right satin look. I will post up a couple of pictures tomorrow. I have also been busy getting the YZ125J gearbox fixed for my 'werks' rider. The powervalve linkage arms also needed attention, she better ride bloody fast now because I was hoping to have the little Noguchi up and running for the 3rd round (10th Feb) but I thought her ride had better take priority because of the 3rd round of the series.
Title: Re: My New Project
Post by: yzhilly on February 02, 2008, 11:12:52 am: Hey DJ 3rd round already ?. how many rounds do you guys run over there ?. CD5 is not far away you better keep pushing that noguchi. I havent even started my 250J engine yet but i can see some late shed nights coming up.
Title: Re: My New Project
Post by: DJRacing on February 02, 2008, 04:46:35 pm: Hi Hilly, yep its the third round next weekend and we have 2 more after that. Rumor has it that an Aussie is coming over for rounds 4 & 5, going to be ridding a YZ400F. It will be interesting to know who it is?
Anyway I have painted the motor so its basicially waiting for a bearing and then put her together. As usual there will be some fine tuning to do but if everything goes to plan this week I could get to run it in at round 3.

Title: Re: My New Project
Post by: LWC82PE on February 02, 2008, 06:55:48 pm: which of the VHT paints is discontinued? is it the satin 'barrel' paint? where is it discontinued from? i need to know who is telling you its no longer avaiable because i think i better get some before its totally gone. doesnt steve cramer have it now?
Title: Re: My New Project
Post by: DJRacing on February 02, 2008, 08:36:34 pm: LWC, I have been told that over here in NZ that the VHT 'engine case' paint (satin black) has been discontinued and they have also discontinued a couple of the other paints. Check with your local dealer and buy up what you can.
This is the VHT paint I use and got so use to it I could vary the gloss level from flat/matt to semi gloss, by drying it in hot or cold conditions and by heating or cooling the part before painting it.
(http://i45.photobucket.com/albums/f65/djracingyz/YZ125B158.jpg)

I will now have to experiment with another product and see if I can get the same results. I am trying CRC black zinc. I will keep looking around because I prefer black oxide, but for now the CRC spray can will do but it will be interesting to see how long it lasts.
Title: Re: My New Project
Post by: DJRacing on February 04, 2008, 06:41:30 pm: Here is a break down of the costing of the Noguchi.

This does not incude my hours of cleaning, painting, polishing, repairing and manufacturing of parts etc.
Nor does it include Danny's labour for the motor building or Brian's work on the frame. I am very greatful for there knowledge and skills.

As yet, I am still wiating for a bearing to turn up, but I'm thinking I should start cooling the beer down.

Dont hestiate to let me know if you think I have over estimated or under-estimated the costings, as I said before I already had allot of the parts but cant remember the the cost of them and some parts came as box lots, so in saying that I think most prices are pretty close.
Title: Re: My New Project
Post by: evo550 on February 04, 2008, 08:25:52 pm: DJ,
Good to see not only are you using the lounge room carpet for the project, but the dining room table is not left out of the equasion.
I eagerly await the next instalment.
Title: Re: My New Project
Post by: DJRacing on February 05, 2008, 05:07:54 pm: Evo550, the parts are clean enough to eat off ;D and there is nothing like having a big steak while looking at a motor ;)
I am still trying to sort out a spring for the rear shock and I'm still waiting for the gear box bearing so I'm at a stand still now. So close and yet so far away.

A friend suggested to me my next project should be my YZ250H, and I was thinking along the lines of an aluminum tank the same shape as the H tank, a new seat foam cut down and re-shaped, billet triple clamps bored out to take the 44mm Fox Forx's, new SM Pro gold anodized rims, DG pipe, and a completely new redesigned swingarm that is more angled, longer and beefer looking. A TonyD Preston petty front guard and opaque sidecovers.

Oh bugger its already been done :( .... maybe I should attempt it anyway.
Title: Re: My New Project
Post by: Nathan S on February 05, 2008, 05:57:33 pm: I think you should do it. :)
Title: Re: My New Project
Post by: DJRacing on February 05, 2008, 06:47:30 pm: Yep Nathan, it would be a good project to do, but I could see the budget flying out the window on it. The tank wouldnt be to bad to make as there are 2 local guys that would be able to make one. The price would probably be reasonable. The swingarm I think would be a harder item to make but if I use a YZ250J airbox I think I could get around the problem of the low mounted rear shock. Of course the Fox Forx are available but at a big dollar value. The triple can be bought from XtremeYZ. Allot of modification would need to be done to make things fit but I think it would be a very cool bike. Anyway I will have to think more on it and its all the little things that add up to make it something special.
Title: Re: My New Project
Post by: DJRacing on February 08, 2008, 04:57:00 pm: So close, but the gearbox bearing hasnt arrived so the Noguchi isnt getting run in this weekend. I have painted the exhaust pipe and I think I have everything ready for the motor to just go in. But with the 3rd round of the series this weekend I will be off riding.
As you can see the washing is out so sorry about that but here are a few photos.

Hoony, thanks for the comment about the sticker. I just thought it would be a laugh to have a period looking sticker.

Ian, I think we will need to have a beer or 2 with this heat.

Andrew the YZ250H isnt running as I smashed the barrel around the base through the exhaust port and across the other side. It has always been in need of a complete restore and I hope to get to it next. I have a DG pipe for it and yellow plastics but I do have to spend some money on it so I wont be starting the resto for awhile until the funds build up again. The noguchi has cleaned me out, I'm only a poor painter on wages :-[
But here are a couple of pictures.

cheers bonehead ;D ;D

Post by: DJRacing on February 21, 2008, 08:59:38 pm: Thanks Bonehead, but it is just a race bike and as the old saying about how photos can lie, you probably need to see it in the flesh.
Will I have got the motor in, the chain on, clutch hooked up and the carb and electrics are all go, I even have spark, but I have to put the exhaust pipe on and I think I will have to reroute the throttle cable.

a total credit to you, while a few other blokes like your sticker, and i do too, my favourite is your garden, it reflects where you spend most of your time, workin on the bike, and thats meant as a compliment too by the way.
lookin forward to CD5

Love this sticker, and apparently others do too. Have you heard from Doug and Gary's lawyers yet ;D.

You have set the standard and the fashion.

It is now the CD5 'Mission' for all in attendance to come up with a similar or better personalise period style sticker. And with the power invested in me ;) :D ::), I declare the prize for 'Best at CD5' as being a night ensconsed in Klub Kevlar being plied with as much free booze as you can handle ;D

He makes and paints scale models and he knows what a bugger it is to start the mower - so now he's also impressed ;D.

Post by: cyclegod on February 23, 2008, 09:28:14 pm: You have a good place to ride, where is that exactly? (to me it looks like the forest riding area just north of Christchurch)
Title: Re: My New Project
Post by: DJRacing on February 24, 2008, 10:29:10 am: No problem Hoony, if I can help you (or anyone else) in any way just let me know. The first race meeting will be March 16th the 4th round of the series here, I hope. I need to iron out any teething problems.
The place I was riding at is about 5mins drive away from where I live, Wanganui, North Island on the west coast. The pine forest runs out to the beach and ya can just make up tracks and trails. Its handy to run bikes in or do jetting as you can have your tools at hand.
I have found the front brake to be a bit weak, the front suspension a tad soft, the back a tad hard and I think just a bit of fine tuning on the motor and she will be good to go.

I knew you would remember. That pine cone still haunts me to this day.
Have you noticed that in each issue of VMX since that day there has been a pine cone discretely placed somewhere in the magazine? Hmmmmmmmm????
vmx42
Title: Re: My New Project
Post by: evo550 on February 24, 2008, 03:07:56 pm: It's quite easy to explain, because the YZ didn't come with a kick stand there was nowhere to place a pine cone discreetly, so DJ has had to improvise, and improvise he has, if you look just to the right of the bike in the first photo you will see a strategically placed "Pine cone" under the throttle tube.......a f%^&$en big van, this is an excellent subsitute and worthy of a mention in the "pine cone placement" quartely.

For those of you scratching your head thinking WTF, I refer you to the cover of VMX mag number 25 and subsiquent ktm 250 article, special atention should be drawn to the kick stand of said motorcycle.

Post by: DJRacing on February 29, 2008, 07:01:23 pm: After work today I took the bike out because it needed a bigger main jet. I have got from a 190 to a 225 main and had to drop the needle to the last clip position. I think I could go from a 50 to a 45 pilot as will but I havnt got one, but I will when I do get it.
Anyway you have seen the video, here are a couple of pictures from this afternoon
Thanks everyone for the kind words.

Post by: TM BILL on March 01, 2008, 02:59:40 pm: Well i have just seen and herd the Noguchi first hand 8) and i can truly say the pictures and video dont do the bike justice.

Congratulations DJ you have done a fantastic job , coming up with the concept to the completed (i use the term loosely as feel the Noguchi will continue to evolve) bike.

It sound as good as it looks and i cant wait for a ride :)
Good on ya mate Bill.

Post by: mainline on March 02, 2008, 08:37:10 pm: Mate, beautiful bike, inspiring effort to get it done that quick. I bought my bike about the same time as you and it certainly isn't anywhere near finished. Congrats.

Post by: DJRacing on March 16, 2008, 07:35:27 pm: Will the final true test day for the Noguchi was today at the Kiwi VMX champs and I'm happy to report that the Noguchi proformed exceptionally well for its maiden race meeting(although I have discovered a tiny hole in the tank). All going well, the next time I get to ride it will be at CD-5.
Title: Re: My New Project
Post by: TM BILL on March 17, 2008, 06:31:44 am: DJ is being too modest the Nogouchi is a bloody rocket :o on its maiden outing DJ rode it to 3 wins from 3 starts 8)

I got a ride on it at the end of the day and yep it goes as good as it looks :)

Post by: VMX Andrew on March 24, 2008, 04:14:01 pm: hey dj...just out of curiosity,what jetting specs do you run in your yz250g..just took mine for a quick trip up the road and back after fitting a new manifold and boyseen reeds and the thing absolutely rips.....gone is the mystery flat spot...but my main concern now is the amount of smoke it blows..its blowing out everywhere....i was running 98 octane pump fuel with yamalube 2s at around 32-1.... :)

Put it into first gear, take off and nail it in every gear. If it still smoking after fifth gear you have a problem :-\ (probably c/c seals). If it clears it was just accumulated oil from standing ;).

I fit seizes in between it wasn't my idea, right? ;D
Title: Re: My New Project
Post by: VMX Andrew on March 24, 2008, 08:23:59 pm: it has been sitting for something like 6-8months...it wouldnt be the crankseals....the whole motor was rebuilt top and bottom only about 12 months ago.... :)
Title: Re: My New Project
Post by: DJRacing on March 24, 2008, 08:40:25 pm: Andrew, its been a long time since I have looked at the carb on my YZ250H so I am not sure what it is running.
Is this the first run since the rebuild? If it is then be thankful that it is smokey, at least the bearings have oil on them.
As for crank seals, they can go at any time.
Title: Re: My New Project
Post by: VMX Andrew on March 24, 2008, 08:49:24 pm: this would probably be its 3rd run since its rebuild...yes ive been a bit slack with takin her for a run every so often to keep the seals fresh but i didnt think they would perish that quick...

They don't 'perish' they harden, and I doubt they would need replacing after 6-8 months. Slight damage of the lip may have been done during assembly but most probably just accumulated oil.

Take it for a thrash ;), and report back 8).
Title: Re: My New Project
Post by: DJRacing on March 25, 2008, 05:24:45 pm: Yeah I agree MX250, a good thrashing once it is warmed up. The oil should burn up nicely after sitting around waiting to be taken to heaven and back, yep a good old fashion flogging is what is needed. ;D

Post by: DJRacing on March 25, 2008, 07:24:35 pm: OOps, My wrench said the piston looked like some overwieght pom was giving it a flogging ;) the only way to keep up with those big brit bangers on a 125, lean her out, keep her pinned and hope for the best. The barrel is in getting a hone and the piston/rings are on the way for the rescue.

Never let a pom pass by.... ;) ;D ;D

Title: Re: My New Project
Post by: DJRacing on July 05, 2013, 08:12:53 pm: Yea I miss that little bike, it even had a sense of humour, albeit in a gangster kind of way.

"If you don't start singing now I'll break your f...kin leg"
Roxanne you don't have to put on the red light ;) sorry Bill ;D

In its own way I think it had 'short-bike syndrome' because it liked to take on bigger bikes in a do or die fashion.

And like a true gangster hitman/bodyguard it looked after its owner and gave him 3 wins in a row to become "The Don"
;D ;D
