I need a set of oversize pistons and rings for my '82 xs400RJ Seca. Anybody know of a source? Already tried Speed & Sport - they only have a set of pistons and do not have rings to match. I have already honed the cylinder once and replaced the rings with stock size and after 5k miles am down to 115 psi in both cylinders. Any help would be appreciated.
