Ok, I got the piston unstuck from the cylinder after letting the cylinder soak in PB Blaster and Kano Aerokroil Penetrating Oil for about a week.

A measure and you might get away with a hone and new ring if no ugly force was applied. No point replacing serviceable parts.

I could not find direct damage from engine failure or even wear, just neglect from sitting since 1991. I drained the oil and it was debris free just very old. Ok, here is the bad news.
The rod and main bearings are stuck too. But no sign of apparent direct damage or wear. ![]() ![]() I decided to pull the motor for a full rebuild. I pulled the swingarm shaft 3/4 of the way out and removed all the engine mounts except the bottom one which the nut came off the bolt but the bolt would not move. I turned the bike upside down and hit the bolt with PB Blaster and some heat, then my impact wrench, the bolt turns freely now but the bolt still will not back out. I am going to let it soak for a few days. ![]() ![]()

I only gently rocked the cylinder and the cylinder broke loose. The base and head gaskets were inract.
