Just bought a Wiseco and took down the engine. There are a couple things I'm not so sure about as far as installing the new piston. Checking and filing ring end gaps - Could someone explain that? I understand I need to somehow check the gap between the ring ends when they are compressed as they are in the cylinder. According to CoeShow in an old thread the top ring should be at .012" and the lower should be .014". Which ring goes on top anyway? There's a copperish colored ring and a grey ring that came with my Wiseco. Can I not just use the rings from my previous piston? Honing the cylinder - Is this absolutely necessary? My cylinder doesn't look too glazed (but what do I know?). If it is absolutely necessary then how do I do it?
