PSI Compression on a RM50

[thestud25]

As title states. I need to know the "good" compression range for a 1979-1981 Suzuki RM50. I have tried to locate a manual and have not been able to turn anything up. Any correct answers are much appreciated.

Thanks

The only mention of psi I could find in the manual.

She runs great, just hard start. Carb clean, good fire etc. I was 98% sure it needed the top end rebuilt, just wanted to confirm the compression psi.
