My DT200WR 1991 3XP Model

FunkeyMunkeyDavid · Guru

do like that a lot,loads of potential biggrin yamaha should have used that chassis for the dtr's,much better shape/handling/off road potential hmm

AndyYam · Guru

Yeah I know what you mean about the potential. I feel guilty having not got it done yet. I've got everything here I just need to get around to it.

Already bought the tail tidy and indicators. New wiring loom, cdi and servo incase needed. Replaced the broken airbox. I've never got it running. The last time i worked on it I got to the stage of trying to start it and got no spark. Hopefully it wont be too long!

I will need to get the seat recovered but really need to get the mechanical bits sorted before i sort out the cosmetics.

costs more than fmf tho

Harry · Guru

Must be mad to sell it that cheap.. looks like it could look really nice

AndyYam · Guru

The pipe came on the bike. I assumed it was the same as the DT125 until recently. It's in really good condition too. Are the photos on that site just representation or are they the actual pipe? It looks very different to the one on my bike.

biggrin when the time comes for my 3xp engine to run, fancy swapping exhausts

AndyYam · Guru

Ha, would love to help out but then id be stuck without an exhaust for mine when i get mine running! I've been trying to source a standard pipe and have been waiting for a call back from someone for ages who has 2 spare standard dt200wr pipes.

whats the power like compared to the 125?

DT200R MACCA · BANNED

dont swap your exhuast m8 their the same just a little diffrence in shape to fit frames you wont get any extra power i run my dtr 200 on a dtr 125 dep and it runs great and if you look on dep.com the 89 dt200 shares the same pipe as the 89 dt125

the only way is YAMAHA DTR · Guru

well they are different on the wr, cuz the exhaust ports wider than the dep for 125

DT200R MACCA · BANNED

well all 3 fit each other and theirs no gain at all just the wr 200 brakets are in a diffrent place and if you look at the dt200r project on here the dude fits a wr200 fmf front pipe to a dt200r which has the same port as the 125 so if wat ur saying is right then it woulndt of fitted/made the bike run poor

This is a DT200WR not a DT200R they are very different bikes. I also thought that the exhaust port was different to the DTR barrels.

As for the power, I've never run the bike. It came to me in pieces and I put it together and other things took priority. I did try start it once but got no spark. I've got a spare loom and CDI to try out but need to have another go soon. It will be once this DTR125 is complete though.

AndyYam · Guru

33bhp on paper though.

hey i would be intersted in seeing how close a wr200 seat would fit a dt125r, i you get a chance could you show us

Reckon you'll need the 200 tank too Only Way, unless you're doctoring the seat somehow. btw is the snorkel same size as the 125 or 230 Lanza size?

to look at yes engine wise no dt200r 3et 33bhp dt200wr 3xp 33bhp the 3xp has a longer 1st gear 2mm bigger carb 2 extra ports a nikel plated barrel and a diffrent right hand engine cover with no oil pump and is only a little bit quicker off the mark than the 3et

the only way is YAMAHA DTR · Guru

the portings completely different and probably compression and the clutchrod arm is on the clutch cover, some dt200wr had autolube, the dt200wr is the road legal version of the wr200 i think and the wr200 can also be road legal ,

GADGET · Guru

Only way ,I like your thinking man

the only way is YAMAHA DTR · Guru

i just want a better seat, so i get more distance from the seat to foot pegs.

and i want to re shape it. i tried to do it with a yz250 but it went wrong, looked good but to short

NEV · Guru

looks ready shaped the 200 one, or is that doctored?

AndyYam · Guru

As you said TOWIYD the WR and DT200R were also slightly different. They had different CDIs and carbs. The DT200WR runs a 28mm TM the same as the later DTR125s but the WR200 used the mikuni tm30ss same as the lanza i believe. The WR also used a plastic fuel tank and the DT200wr had a metal one. As you say the WR has different gearing which is where the WR comes from. Wide Ratio I am told.

I think mine is a bit of a combom between a DT200WR and a WR200. I think that at somepoint the engine was swapped as the engine shows no numbers just "3xp" and it currently does not have the auto lube fitted.

The seat is quite different from the 125 and as Nev says if you were going to swap i think you would need the 200 tank but then the plastics etc etc would be an issue. I can get some more detailed photos of the seat and its fittings if you wanted but Imo it would be abig job and you would have better results working from a DT125R seat base and building it up.

Nev not sure if you were asking about my snorkel but here is the parts diagram for the airbox, as you can see its veyr different from the Dt125 and lanza style snorkels.

That was taken from a parts manual for a WR200RD. If anyone wants a copy of it, pm me your email address and ill send it across.

hi whats the I.D of the silencer tube?, i'm torn between an fmf or dep and i know its a long shot but maybe my dep silencer will fit the 200 front pipe

AndyYam · Guru

The silencer appears to be a DEP. Its very stubby. I don't think it has any markings on it and is very scratched up. When I'm next out there ill take some detialed photos of it and get some measurments if you like. Let me know what you need.

the only way is YAMAHA DTR · Guru

hi thanks. a pic of under the rear side cover would help, i can adapt the angle if the internal diameter of your silencer is the same as mine

AndyYam · Guru

No problem I'll sort it out tomorrow. I'm pretty sure it will be but will double check. Even of not I'm sure you could make some kind of tube to step it down from whichever side is too large.

the only way is YAMAHA DTR · Guru

i orderd the same front pipe as you biggrin

needs to be same diameter or it will restrict the flow

AndyYam · Guru

Ah yeah good point. Unless the silencer is wider. The DEP DT one opens out right at the end to slip on doesnt it?
