Compression - '78 Garelli SSXL

Ralph Dickenson /

I got a reading of 90 psi compression for my '78 Garelli Super Sport XL. Does anyone know what I should get? Is this correct? I can't start the bike, so I am attempting to check it out.

thats low, but it should still start

A healthy ped engine will have better than 145psi. It may not run at all with 90..
