. Posted December 27, 2003 Report Share Posted December 27, 2003 How old is your top end? Those are good numbers for your elevation and 21cc domes. Keep doing what your doing......your top end seems to like it. Quote Link to comment Share on other sites More sharing options...
fixitrod Posted December 29, 2003 Report Share Posted December 29, 2003 Compression wise you are fine. You can kick a little harder on one and get different numbers. Checking the compression doesn't tell you the condition of your piston skirts though. If you've never changed your rings, and your compression numbers are that good, your skirts probably aren't worn either. I'd leave it alone. Sounds to be strong.
