Hey guys, I finally pulled the jug to replace the base gasket, and was about to reinstall and realized there is no pins on the Piston for the ring gaps. Not sure where to clock them. The Piston only has a number on it, not related to size, so I don't even know if it's stock size or what. The top ring seems smaller than the bottom, is this normal on a running engine? It had good compression a two kick start bike.
