I have the bad cylinder here off the KX60 I just rebuilt. I can get that measurement for you.

Edit: Just went outside, that measurement is surprising hard to get, LOL. My micrometers are all too big to fit into the cylinder, so I tried to use the depth gage on my calipers. I couldn't really it in through the port from the outside with anything to use as a stop so I measured a few times and "eyeballed it" and consistently got around .865-.867".
