400EX jetting

[Da300EXer]

I have a '00 400EX with a T-4 slip on, WB rev box, K&N filter with outerwear and i run the lid on. i dont know whats in it now but i think it is too rich. does anybody know what it should be?

put a 150 main in it and and put some holes or some filters on your airbox lid and take the outerware off that thing is useless, but if you take the outerware off then you will need to keep your KN clean ... might need to clean it once every 2 weeks depending on what you do. if you are running rich then that means you need more air flow so try to put some holes or filters on your airbox lid or something, maybe adjusting your needle in your carb: should be on the 2nd notch from the top. hope this helps

Uh Oh, somenbody sounds like they know what they are talkin about. But, He lives in New York, the elevation is way different, therefore jetting will be different.
