    THINKING 250f engine

    So i was thinking for my hybrid the best bet would be to strap a 250f engine onto it and race 350cc 4 stroke/200cc 2 stroke class. That engine with a bore kit would wreck all the other quads ive seen out there so far.

    anyone have any experinace with putting a 250f engine in. i was thinking an 06 crf250r engine.
