John,
I experienced the same on my Honda CB750, which had been parked for ten
years,just after a short ride. The water build up when not driving the
engine warm/hot is disasterous. Suppose you have the same problem.
I got the pistons off cyl 1 and 4 out quiet easy, but 2 and 3 where also
frozen. I hung the engine to the ceiling of my garage. Being able to
slip a binder just under the cylinderblock, all the force was on the
cylinder/piston surface. Just a few cm above the ground, hitting the
pistons hard with a piece of wood and a hammer also, it came loose after
half a day. I did not use the blue wrench. But it would have been my
next solution. Not heating up to much and on one spot, and when 'hot',
scare it with WD40. The frozen surfaces will loosen bit by bit.
Take your time. No hurry.
Good luck.
