I am looking at getting a Cool Head for my Banshee. I have heard the Pro Design leaks is this true? What other company makes cool heads adn which one is the best? What is the smallest domes I Can go with without running race gas.

 

I have a coolhead from ADA Racing. It is great no problems. I run 20cc domes on 92 pump gas and octane boost with no problems at all. Go to http://www.adaracing.com they have a list of the domes and what octane fuel should be ran with them. Hope this helps some.
