I can understand new rings, but why a new piston head, is it cracked? So if their are scratches in the cylinder, should it be honed? I know that I have some scratches in my cylinder, but I thought that this is normal. I have also noticed a decrease in power, mainly climbing hills. I don't know if you can answer this for me or not, but is the cylinder supposed to be scratch free? I would think that is impossible. Hmmm... Thanks for the help. oh yeah, maybe you already answered this, but where did you get the needle bearing at and how much did it cost? How much did it cost to hone your cylinder out?
