What main jet should I use at sea level with stock opened up exhaust & airbox?? I have a ported exhaust header and a WB intake cam.

I think I got a 165 or 168 main at sea level. Look in THUMPERTALK.COM tech section.
However the board has been down for a few days for some reason.
I need to get to my profile as I am trying to get together to race this weekend..JR

OH yea this is not for S-model only 400e offroad with fcr carb.
My buddy has a 170 main but he complains of needing power and I don't.

I ran a 165 main in my E with open airbox, FMF power bomb, and FMF Power core IV2. I'm right at sea level.
