Compression test

Message

Hi,
I need to know how to rate compression tests. I guessing they're different for different bikes, but is 120 psi good for a yam xs400??

Also, the gauge doesnt climb right away to 120 psi. It takes at least 4-5 compression strokes to climb to that rating. The engine does idle well, so I neednt worry for now. I wonder if I will have to look into the engine sometime soon or is it all OK??

Thanks
Kartik

120psi is fine, and it's supposed to take a few turns to get it to that point!

All systems go.
