Getting ready to tear my top end off for smoking reasons. Going to remove the head and jug to replace the rings (hoping that is the issue). I was searching for a gasket kit and rings and stumbled across a kit on Ebay with gaskets and a Namura piston with rings pretty cheap. I'm not even sure I need a piston or if I need an oversized piston. I've read some mixed reviews on the Namura piston in bikes and quads, but not on a SXS. Has anyone ever used one or had any experience with one?
