Depending on what size the bore is now and how bad its scored you may be able to have the cylinder bored instead of resleeved.Make sure you ad the aluminum thrust washers and RM pin bearing to your list.Stupid question but you wouldn,t have happened to run the quad out of gas or very low.I,m no expert but the specking on the top of the piston suggests you were really lean and some detonation issues.Tthe rings obviously look nasty as well.Like I said I,m no expert so maybe one of the builders will chime in.
