Yeah, is that good or bad ? did you hold the throttle open while doing the tests ? I thought you should be over 220 PSI for that compression ratio.

wow, no wonder you can get away with 87 octane in these bikes. I thought it would be much higher. I don't remember seeing the spec in the service manual.
