changing coolhead domes?

[jas250r]

Anyone out there change dome sizes? I want to know how much of a difference it made for you when adding more compression with a smaller dome. I just switched to a 38 pwk airstryker and gain a lot of topend power but lost a little bottom and was wondering if going from the 22 i run now to a 20 would be a big change? i already run race gas so that is no issue.

If you run a stock cylinder with race gas, go with a 19cc dome, HUGE torque gain at low rev.
