Finally an update: I spent some time and fabricated a couple bolts fitted with a grease nipple and tried last night to use the grease gun to put some pressure on the pistons, but no luck.
I took out the rockers and made sure the valves were all closed, but apparently they aren't sealing correctly and I got a big gob of grease pushing past the right-side valve and coming out the exhaust port; the left one didn't leak, but instead pushed the grease UP one of the long head bolt channels that keeps the head on and was coming out the space where the rocker arm locking pin goes in.
I might try unbolting the pushrods and taking out the crankshaft, then try to find something I can slip down over the rods and push/pound against the pistons themselves, but at this point I don't know. I originally just got the bike for the tank and decided to try to save it, but I don't know if that's going to happen. I wonder what would happen if I just took it out into the yard and overhanded it with a 20-lb sledge...
Ideas...?
Freeing Frozen Pistons?
frozen pistonsDrill holes in the tops of your pistons and take them apart. They are probably junk now anyway.
You could easily fabricate a 'solid' head gasket from alloy sheet, i.e. head-bolt holes only, no bores, bolt it all up & then pressurize the cylinders only, bypassing the valve gear.

Re: Frozen PistonsThe grease will be captured between the steel plate and combustion chamber as the spark plug hole is in the head. ...........lm
