ok i have a 400ex and i put a stage 2 hotcam in it and i bought a dyno jet kit. I have the stock pipe but i took the spark arrester out and i also have the stock filter and i removed the airbox lid. Pluse i run kltoz nitro. The guy that works at the dyno jet company says to put a 170 main and 3 1/2 turns air/fuel and when i started it up it smokes white somke and i was wondering why it smokes.
