Thanks for your replies.
Re bleeding green, sounds like a good idea. It's just gotten rediculous is all.
Yeah I've already seen the horrible pictures, other wise I wouldn't have been concerned about running it. The piston and bore does measure up close to new specs is the odd thing. The piston had bad blow by marks. I wonder if it had a guts full of sand or was used before the cylinder was sleeved. I'll swap it out because I couldn't handle having this blow up now.
Did the Wiseco pistons ever get that cavity on the outside removed or was it just the custom ordered ones with the window in them?
Thanks and enjoy your Christmas.
