i have a 250r with a 330 powervalve cyl, in it. i have an opprotunity to pick up a pred. motor real cheap. my Q is if this will fit hiegth wise. im happy with my machine now but am considering this motor for this quad down the road if my motor ever self destructs. also if this frame wont work, is there any companys that make a frame for this motor where all of my 250r suspension components would transfer. any feedback is appreciated. thanks
