ok so my neighbor let me have an old suzuki street bike. it had been sitting and the engine is coroded and destroyed not even fixable. it is a street bike however it is doable for off road. it is a smaller bike and i dont know what cc it was im thinking probably a 400 or 450. would it work to put an engine of a 350 dirt bike into it. also if i took the things that made it street legl off took off the front fender or raised it dould i get it registered for off road use. plzz answer asap.
