Hello all, I am having problems getting the ring gap in specs per service manual on a brand new wiseco 87mm piston kit. I took my jug to a reputable shop and had it bored at .002 clearance with the piston. Put brand new rings in the cylinder to check clearance and its out of spec at .017 top ring, .023 second ring. Manual says I need .008-.014 for top ring, .014-.020 for second. It is however within service limits which is .020 for top, .026 for second so I decided to run with it and guess what, it lost compression during first two minutes of running during break in. Took it all back apart and nothing is damaged, rings still have the same gap as before running. What to do now? Maybe order a set of 88mm rings and file the ends down to spec? I assume I have to go with wiseco rings for a wiseco piston correct?
