After a valve adjustment, my '72 CB450 was spitting out about 125ish PSI. Decided to pull the motor. 24,000 miles.

I think we're derailing. Stock is 190 PSI. His compression shows 130 PSI. I compared the gauge he used with another gauge, and it was consistant.

However, I keep reading stories that you should use a small engine compression gauge.

Have any of you rebuilt motors, and done a compression check? Was it always back up to stock? What gauge did you use?
