2004LEBanshee Posted November 13, 2003 Report Share Posted November 13, 2003 I read my compression on both cylinders and it read about 106 for both I think. What should a stock bike be 110? And what would a noss head with 20 cc domes make it? Also what is 6.5:1 mean for compression? Is that another way of doing it? Quote Link to comment Share on other sites More sharing options...

Depends on your elevation...128 at sea level and drops at higher elevations....A 20 cc dome will bring it up about 30 psi... Quote Link to comment Share on other sites More sharing options...

SDD Posted November 16, 2003 Report Share Posted November 16, 2003 I checked my motor over the summer... 80 degrees in San Diego (300-500ft elev.) and had 125 on both sides after 4 hard years of riding. Quote Link to comment Share on other sites More sharing options...
