I have an 06 bamshee with toomey t5 pipes, reed cages cut, reed spacers, boost bottle, timing advanced 4 degrees, and rejetted.
I am going to have the cylinders ported, when I buy a cool head. Not full drag port but what they call MX port job. What cc dome would work best for trail riding and drag racing and still run on 93 octane and not destroy a stock piston and rod.
Thanks a lot!

 

20cc domes

Go to www.bansheehq.com and they will be able to provide you with more info.

 

Don't forget to also check out Noss banshee heads. They use the same domes as Cool heads. They got a table on their site that shows the kind of compression you get out of each dome. They also make lots of other great banshee related products.

I would run 20's for 93 fuel.
