I was wondering if there were any kawasaki atvs that i could put an 84 kdx engine in, the engine is in perfect condition. Thanks for the help.

 

What you want to do is custom so you could basically put it into anything you wanted. One thing to think about is that the motorcycle engine's transmission will be lighter duty than a quad transmission and will probably break down in a short time. Also the clutch will not hold up to the abuse of driving two wheels.
