HEAD VOLUME ?

[Joe]

I'm getting a new CMB 45 EVO. I've heard the head button volume needs to be changed. If I make a new head button what volume should I go for? Also What changes would you see or look for by making the button volume bigger or smaller on any engine? Thanks

What fuel and pipe are you going to use with the engine? Is this engine going in a mono or hydro?

It is going in a seaducer mono, run on redmax 60% with 18%oil. Pipe will be a Andy Brown parabolic.

have you checked to see if the bore is the same as the cam/hydro motor . if so why not swap buttons as evo's are designed for lower nitro . it may save you alot of time. ... but i guess it figured that already
