I was posting this out of mischief and wonderment... is it possible (w/ fabrication, and welding of course) to put a XR650R engine into a CRF450R frame??? I have access to both and was wondering if it could be done...(most likely I would try but messing up a CRF450R rolling chassis would be dumb and not being able to use it would suck,...but...) has anyone seen it, or heard of it for that matter, I was going to use it for street holliganism, and such...:bike:
