Had the cylinder off of it last night, cleaned up some of the ports. I also noticed that the sparkplug looked like it really wasnt deep enough into the cylinder? So i turned down the sparkplug mounting surface, now the spark should be in the center of the fuel. This was a trick on some mid 90's hondas. Also this motor has not been run much but it apears that the chrome is wearing thin. Has anyone had a cylinder replated?
