  1. YZ125 engine in Raptor 250

    Raptor 250 Discussion
    Has anyone installed a YZ125 engine in a Raptor 250? If so, any major problems? The two issues I see are 1) mounting the rear of the engine into the swingarm pivot bolt. 2) exhaust fitment/frame clearance. I think both can be solved with some basic cutting and welding.
