Need some jetting suggestions for the 400EX. I have a Yoshimura Complete standard exhaust, K&N air filter, air box lid stays on! and a stock engine. any one have this same setup or pipe and filter with air box lid on? or know someone who does. what jetting are you running? Slow:? Jet needle clip position:? Main:? Pilot screw:? any suggestions are appreciated. Thanks.

Listen man I'm probably at around the same elevation as you and my bike runs awesome. I have a K&N with holes drilled in the air box lid, a yoshi standard full system, slow jet is STOCK, 170 main jet, needle on third notch (down from the top), and the mixture scew is 3.5 turns out from being all the way seated. I repeat I am running awesome and strong from bottom end all the way to the end of the power band.
