I suggest you assemble some kawasaki 600 ninja`s 4 cylinder 100 hp engine. It will last, you dont have to rev it to feel you`re in a rocket, it will accelerate steadily and with enaugh torgue.
if you put some 1-cylinder 250 cc 50 hp motocross engine, it will not last long and have to be rev ed all the time.
