From the oil tip, I found that the rings were leaking by. I tore the top back down and checked the gap on the rings, both the ones I just put in and the new ones. The gap on both was .008, which according to Wiseco is about right (.004" per inch of bore = .007"). The part that really has me stumped is I found several vertical scores on the cylinder, there is only one that is deep enough to feel with my fingernail and that is just barely. Also there is one single score on the piston itself, it does not coincide with any of the marks on the cylinder though. So where did I go wrong, does Wiseco offer more than one size piston for the 65? Our cylinder is an A, there are some stampings on the top of the piston, a bunch of numbers and then below that a "cd". And most importantly where do I go fom here? Sorry to keep bothering everyone with my problem, but I would really like to know where I screwed up so as not to have a repeat perfomance!
Thanks in advance,
