Once again I turn to you for help on my maiden voyage with my first frame up rebuild. I have entrusted my 850 MkIIA to a trusted mechanic, but have decided to attempt this next project myself. Or at least as much as I can do...
The bike in question is basket case '72 750. It belonged to a dear friend who bought it new, but over the years let it slip into disrepair. The engine/primary/gearbox subframe spent some time outside, and the engine is stuck. Tonight I removed the head. Oh, my...... The pistons are rusted in the barrels. How bad, I don't know. But this isn't good. I sprayed around the pistons with penitrating oil, and will continue do to this for a few days. But I am concerned this will not be enough.
What else to do?? The barrels won't come off without the pistons free, and I don't want to risk damaging the crank by pounding on the pistons trying to free the barrels. Any suggestions or methods to try would be helpful. Thanks again to all that reply...!
