I suspect that I will go ahead and do valves and rings while I open it up. To answer your question, I have 147,575 on the odometer. I trust the individual who tested it for me to know since he does a lot of motorcycle repair.

Both sides seem too low. Difference should never exceed 15psi. Did you have someone hold the throttles wide-full-open while you cranked during the compression test? Biggest error. Throttles must be open. If you did it correctly, then those readings predict you will now be doing a valve job. How many miles on these heads?
