I just did a couple of tests that you might be interested in.

I took a measurement at cold with an old piston/ring (about 5 races) and it measured 95 psi.  I warmed it up and measured 110.

Looking at the piston is was past its prime.  So I changed it out (new top end) and now I’m getting 110 cold and 120 at hot.  Seems like I should be getting more pressure out of it.  Do you know what this could mean?  Worn out jug?  The cylinder is pretty darn good…  If I had a new cylinder it would be nice to try out.
