tdod101 Posted December 16, 2013 Report Posted December 16, 2013 Have a chance to buy a cool head with 18cc domes, I tried google but couldn't really get a simple answer about what domes are or what they do, also why are there different size domes Quote
tdod101 Posted December 16, 2013 Author Report Posted December 16, 2013 Nice, thanks zilla, I will have to look into it a bit more. I've read a stock is 22cc can you get away with pump gas on a 20 cc non ported motor ? Quote
Nightmare Posted December 16, 2013 Report Posted December 16, 2013 A lot depends on elevation. I'm running 18's at 5000ft and comp is at 140, and that's on a fresh motor. Quote
Nightmare Posted December 16, 2013 Report Posted December 16, 2013 You'll be running race gas with those dome and elevation. I forgot to mention i'm still running 91 pump with no problems. Quote
Jereme6655 Posted December 19, 2013 Report Posted December 19, 2013 with stock porting and at 500 ft you'll be too high on 20 cc domes Quote
