Thank you, the rings on the pistons only have a couple hundred miles on them. I was thinking with a fresh bore and hone they may reseat ok. Just gathering parts for an engine build right now. Currently putting together a XS650 for the wife. Have to finish that project first. My 750 runs great now,just toying with the idea right now. Have had these pistons in storage for over 25 years, waiting for my stocker to wear out, don't know if i will ever wear it out
