Hey, well me and a buddy was sittin and talking the other day and got an idea, how hard would it be to put a rancher or a 400 foreman top end(block, head) on my 250EX bottom end, is this possible, will it bolt up, if so what are the advantages and disadvantages? All info will be appreciated, thanx, Bill.

 

Anything can be done to an engine if you have the time and the money to put into it. If you can bolt a 400cc scrambler top end to a 250R bottom end with some maching and matching, then i would assume it's possible to do it to the 250ex and foreman 400. But i don't know how and what the advantages would be.
