Tri-moto 200 question

[shadix518]

What all motors will fit in the 85 Tri-moto? i have the original motor but trying to decide if i should just do a rebuild or go to a different motor?

[shadix518]

well mine is chain driven.....so what do you think?

[Yamada]

oups, I thought it was a 200e.
Let try again. I think all chain driven ytm-200 engine are identical.

[shadix518]

well problem is finding one if i goe with that same engine ill just rebuild the one i have but if i can fit bigger or another type like a 2 stroke i might go with different motor

[Yamaha_Rules69]

There are basically no other engines that will bolt in.I wouldnt try to put a two stroke in it either, and it just wont fit....... Just rebuild the motor you got. The ytm 200 is what it is.

yea i know just seeing if it would be cheaper ot just get another motor...do you know of anywhere to get the parts to rebuild it the only thing ive found is rings,sleeve and gaskets on ebay...

[Yamaha_Rules69]

Is it just the top end that needs done? Check denniskirk.com or rockymountainatv.com or somthing along those lines. They would have it for sure.

Besides gaskets and rings, what else do you plan on needing?

[shadix518]

well if im rebuilding it i should replace all the bearings and such?? if not great be a cheap rebuild...and when replaceing the rings whould i need to replace the sleve or just hone the cylinder?

[Yamaha_Rules69]

you should really get a manual. You do not need to replace the sleeve unless it is on its last biggest bore, or if it is severely scored. Which bearings are you talking about? If you just rebuild the top end, you dont have to split the cases or anything as long as the main bearings and lower connecting rod bearing are okay. And usually in a 4 stroke they last damn near forever.

[shadix518]

yea bearings are fine no problem their the only reason for the rebuild would be due to it casing massive blowby shooting oil out of the breather tube that attaches to the airbox from the crankcase....so the rings are bad or their is a problem with the sleeve right??

[shadix518]

also i know its a ytm200 but i dont know if its the tri-moto or the ytm200e/r model
can anyone tell me so i know i get the right parts?

[MonroeMike]

It's a YTM200N

[shadix518]

is that the tri-moto?

[MonroeMike]

Yes, one and the same. Yamaha Tri-Moto YTM200N
