You (I) don't hear the term compression ratio used much in the two stroke world AZ, but there is a formula that can be used to calculate that info;

Generally speaking, if you get readings over 100psi and no more than a 5% variance between cylinders I believe it's considered fairly good. Keep in mind I'm just a shade tree / apprentice / rookie kinda guy, maybe one of the true technicians can enlighten further?
