I have a Komoto TL250C ATV that I purchased a few months ago online. The engine is a 230cc 4 stroke and the company that makes this is Huanan Motors which is a manufacturer of some Yamaha products since 1994. I have tried searching through past Yamaha products to find a similar motor but have had no luck. Is there any way to cross refence the motor to find other parts that will work with it?

 

is it a single cylinder liquild cool engine with a cvt transmission?

 

Its a single cynlinder, air cooled 4 stroke, 4 speed with reverse. Reverse is also in the foot shifter.

 

Dont know if this helps but here is a pic of the engine.

try going to www.bikebandit.com and look at the early 80's yamaha xt 250's and see if it looks simalar. it's going to be hard to pin point the exact year.
