shortys racing Posted January 13, 2004 Report Share Posted January 13, 2004 how much compression do you run on your quad, i was looknig at 21 domes and its not gonna raise my compression much so i wanted to know what i could go with while still running pump gas 20cc domes would be the same as a shaved head .030.....about 10lbs. per cc size. That would be ok for pump gas, but you should run super. not regular!! Quote Link to comment Share on other sites More sharing options...
