AKheathen Posted August 16, 2010 Report Share Posted August 16, 2010 still check the jetting when you switch, and watch out going to lower elevations Quote Link to comment Share on other sites More sharing options...
ELKARACING_SHEE Posted August 16, 2010 Author Report Share Posted August 16, 2010 still check the jetting when you switch, and watch out going to lower elevations oh yes, definatly, i wont forget about that, seems to run richer here at the higher elevation, i was going to lean her out, but since im changing the domes, ill keep it the same, and see what happens, and go from there, once it runs on premium Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted August 16, 2010 Report Share Posted August 16, 2010 I ran 19cc domes at 2000-2500 ft elevation with +4 deg of timing. I had 150/150 psi compression with my snap on compression gauge. I ran it on 90 or 91 octane fuel with no problems. Quote Link to comment Share on other sites More sharing options...
TeamRealtreeHD Posted August 16, 2010 Report Share Posted August 16, 2010 There are guys locally running 19cc domes, +4 timing on 93 pump. 1300-1500 feet ASL I'm not one to risk it though. I'd run 20's. Quote Link to comment Share on other sites More sharing options...

I'd run 20's. yeah, i talked to a guy, here locally whos got a banshee as well, and he's a big fan of them, he said he had some 20cc domes at home, he said he would drop by, and let me try the 20's out and see what happens Quote Link to comment Share on other sites More sharing options...
shanYE west Posted August 17, 2010 Report Share Posted August 17, 2010 Just to add a lil food for thought.. Not all domes are the same.. Some designs are more prone to detonation then others.. Just because one 19cc dome is fine dont mean the next 19cc dome will be too. This is why its important to know where the domes came from and who designed them.

jbooker82 Posted August 17, 2010 Report Share Posted August 17, 2010 Mine were pro designe 19cc domes. My cylinders were also ported. That also makes a difference. Quote Link to comment Share on other sites More sharing options...
