I finally got off my ass and pulled the top end apart to replace the cam chain and get my valves done. My cylinders are within tolerance so no boring required but I'm having a bitch of a time finding stock rings where they don't want an arm and a leg for them. I found these http://www.ebay.com/itm/161344396432?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT but no MFG matching part # to check them with. Just looking for experience to chime in and give me an opinion... thanks
