I have a 2001 kx 250 that i've been running stock for awhile, but i needed more power. I bought a FMF Gold Series Gnarly pipe, FMF Powercore 2 silencer, V-Force carbon fiber reeds and a TWIN air filter. So obviously i'm going to have to rejet my bike, but i have NO idea of how much bigger i have to go, will i only be needing 1 or 2 sizes over stock? or will i be going much bigger? or even smaller because of the changed powerband? I'm going to set my bike up to run in the oregon sand dunes, so its pretty much at sea level. I know i'll be playing with them for awhile, but any help on where i should start would be VERY much appreciated.
