Amazing what effect a lock down has, must have a go, could be a sprag saver?
Yup, I reckon COVID's got something to do with it. Added a few kg and that "what am I gonna do now" feeling.
The bike is actually pretty good compression. 130 psi last I checked which was only about a thousand miles ago. I have been able to start it hot in the past but never dead cold so that was a genuine attempt with no idea if it would work or not.
At some point Brian I did do a cold vs hot compression comparison but can't find those stats. It would be interesting to know so I'll do it again and post.

I did a cold -VS- Hot comparison also,after I asked the question. You beat me to the post.
I noticed that the cold graph does crank slower ( as you mentioned) evident by the spacing of the peaks and returns closer to 0 between peaks. I did a test with a known pressure applied to the tester to compare with the graphs pressure scale and there is no correlation. Approximately 100 P.S.I. of constant pressure applied to the tester will cause the graph to register appox. 142 P.S.I. My conclusion is the calibration has to be factored with the speed of the rise in pressure and the volume of the hose and fittings and is at best a good approximation,( as also mention here on this boards pages) But a very good indication of evenness of individual lobe sealing. Just had to scratch my curiosity itch.
