jetting question.

[trx400EXtreme]

I have an fmf q2 pipe on my 400ex. Does anyone know what the right jets to put in it would be.

Thanx.

Elevation, state, other mods, ???????
But im gonna guess that its a stock quad other than your exhaust. So i'd say go to the dealer and pick up a few different brand keihin jets grab a K150, K155, K160 now its all trial and error.
