Compression Requirements for a 196 1 CA77

Hello!

I just acquired a 1961 CA77 in running condition.

However, it has only about 80 lbs compression in each cylinder.

Does anyone know what the original compression was for this bike?

And what is the minimum compression needed? It seems to run okay at 80 lbs.

Thanks!

Kurt
