03banshee20 Posted June 14, 2011 Report Posted June 14, 2011 Will it hurt my stock banshee with cool head and 22 cc domes if i dropped 20 cc domes and still used pump gas (93) would i be alright?? Quote
Jereme6655 Posted June 14, 2011 Report Posted June 14, 2011 depends on alot of other factors......we need to know ALL the mods on your bike AND what your elevation is before we can give a decent answer... Quote
mikechief Posted June 14, 2011 Report Posted June 14, 2011 Elevation has nothing to do with octane . figure out your uccr ....shoot for 12.5 Quote
Jereme6655 Posted June 14, 2011 Report Posted June 14, 2011 Elevation has nothing to do with octane . figure out your uccr ....shoot for 12.5 nothing to do with it immediately......but they do play a role with each other... elevation has to do with amount of air molecules in a given area......more of them equal a better breathing engine which means that you get more compression in each stroke of your piston meaning more octane is needed to make sure the fuel stays stable under the higher compression so that it doesn't pre-ignite....... so how does elevation not have to do with octane?

lms1977 Posted June 14, 2011 Report Posted June 14, 2011 have you done a compression check with the 22cc domes ? Quote

Dome design and compression ratio determine octane . Neither of those are affected by elevation. I would buy 20cc noss domes if I didn't have a shaved head Quote
