i saw a CRF at the races yesterday and im thinking it might be sick to race next season, What is the ballpark for a used Full Walsh/pep CRF with an extra engine, its around an 03( not sure) its all white. Also hows the maintence on a CRF engine in the quad frame? do they break often? i would guess an aftermarket frame would be much stronger than a stock 450R frame also...thanks
