the piston has a ring of foreign material, preventing its normal in-out movement.
the piston must be removed to clean and polish the piston and surrounding seal area minimum to restore its normal range of motion
there is no way around this, no cutting corners, no tricks, no shortcuts
You MUST remove the stuck piston to accomplish its restoration to service again
If you put it back together as is, it'll stick again.
note the pic...piston has the ring of solid goop and behind it junk. Yes extreme but a visual example of what hides on and beneath stuck pistons. Note this old Suzuki Intruder went back into service after clean and polish and in this extreme case seal replacement was called for. Yours won't be nearly as bad but the ring will be there to some degree...hence why it is sticking.
