We have a 03' 400ex with sparks x6 exhaust, stage 2 hot cam, no lid, and a uni filter... Where would be a good start for all jets...

WOW... it says to run a 155 jet... we already have a 155 jet with the lid off, baffle out, and uni filter... now what...

we pretty much have the same stuff done to our quads.right now im running a 42 pilot and a 170 main. temps range anywhere from -10 to 35. in the summer i run a 38 pilot and a 160 or 165 main.i cant remember but i think a 165 main. o and the temp is anywhere from 40-90s.
hopefully this helps.
