I just pull the head and cylinder off my bike. The reason was it was burning oil. I plan on replacing valve seals. My question is about the piston and bore. It is already .040" over, and isn't real beat up. It has about .001" taper and it is .0003" out of round, and has little scoring. I can't find a 84.25 or 84.5 piston. And If I go to 85mm I read my compression increases and gotta run race fuel. Not sure where to go from here. Buy stock used cylinder, hone it and replace rings. Go to 85mm. Any advice would help. I'm not looking to increase power and compression. just want reliable good running bike. Thanks guys
