I am in the process of rebuilding my 98 KDX 220R for the first time and have a couple of questions. Before I put the cylinder back on should I hone it out or not. Where it has the nickle cell coating should I leave it alone. Also could some one give me the ring end gap specs for the 220R I'm using a kdx 200 manual to go by and it says that the range is from 0.15mm - 0.35mm with service range at 0.65mm. When I put the new ring in to check it I'm getting 0.32mm:think (The old ring gap was 0.63mm) I am hoping this will get me through the season and this winter may have to do something with the motor. What is the common procedure once you get to your limits, bore and sleeve?
