I would love to come across a kfx400 chassis to put my kx540 motor on. I would never buy another quad ever

 

do it up man. i am sure you can find one around some where.. i will keep an eye out for one for ya.

 

well not to be a smart a$$ but actually the kx250 engine or tecate 250 engine fits the easiest of all into the mojave frame. just change some motor mounts. some people have already done it to. i think about 3 or 4 ive talked to. if your talking about size of rider then well that depends.
