I'm Guna buy a cool head was wondering what size domes to get I live in lower Michigan I run race gas in my quad do some motocross riding dune riding and trail riding what some size would be best please help thank you Quote
Ayesully810 Posted October 19, 2017 Report Posted October 19, 2017 is your crank welded? that's something you want if your gunna start raising compression. also have you cylinders been ported at all? if not 20 ccs should put you around race gas numbers. You should have around 165 to 170 psi of compression to run race fuel. Order you a cool head from driveline in Ortonville, MI (248) 793-3535 or email [email protected] and get their billet cool head and they will cut you the domes that you need. Quote
sleeper06 Posted October 19, 2017 Report Posted October 19, 2017 Well motocross I like higher compression than dune riding so you could go somewhere in the middle 19-20cc . Driveline is a good option, he uses a good angle and band width compared to an off the shelf pro design dome Quote
