I have searched but can't find what I'm looking for and I know I have seen it somewhere. Anyway how big of a bore can you go to on these cylinders and not have to re-sleeve. These cylinders can just be bored and then pistons installed, right? These don't require re-plating, right?

I believe most say 84mm but I am pretty sure there are some out there 85mm running with no problems. No they do not require any replating..
