I use my crf50 for pushing a dragbike back from the topend of the dragstrip and to go get food from the concession stand so i don't want a clutch. I.want more power. Can i buy an aftermarket motor( Lifan ,GPX,etc.) and put the auto clutch from the 50 in it or just get a trail bike 88 kit and probably save my self a head ache ? My buddy has a sik50 and he was wondering as well.

 

yes to all of it.

 

if you buy a new motor tho it should come with a new clutch, just make sure you buy the motor w/ the auto
