I have a Group K 61X sitting on the shelf that is to 84mm. I just measured the sleeve thickness at the skirt and its around .075" - .080" ...
Personally i wouldnt go over 84mm, but some have.

A buddy has a cylinder that was run at either 85 or 85.5. Paper thin. Ran it for years like that!

hey big K I think Chris's was 85mm but not sure it was run ALOT at that bore was it? I know he ran it at 84.5 forever though. Freakin tinfoil sleeves LOL. I think the salt crystals held that motor together. It amazed me that his shiot ALWAYS ran and it was SO CRUDDY and ours were having salt water issues all around him. LOL LUcky F'er.

But yeah, his chit never been pretty but runs good!!!!!!!!!!

i have seen them a 85mm on a stock sleeve.
Since I've already sold the cylinder that I imagine this thread was started for. My opinion on this is... The very bottom of the sleeve that sticks out beyond the base of the cylinder is thinner than the rest of the sleeve. The thing is, the bottom of the sleeve, that everyone sees, doesn't really see any where near the forces that the top of the sleeve sees. The rings barely go down past the exhaust port. So the most loading that the base of the sleeve will see is the piston skirt tapping it and even then, the cases are flush with the bottom of the sleeve so the cases are actually reinforcing the sleeve. The worst place for the sleeve is between the intake ports where it has the least amount of circumferential area. Maybe one of the guru's will correct me but that's how I see it.
