i just traded an xbox 360 for a 98 cr 250 with a blown top end the cylinder has a pretty deep scratch in it im wondering if its to deep to repair i took pics but my camera sucks at closeups but you can tell its signifacant damage. im thinking about getting it sleeved but heard some negative stuff about doing that. any suggestions? id also like to know about the bike overall,ive heard these bikes are pretty fast. my last bike was an 01 rm 250 jetted and piped.
