Hello! New to this forum, just picked up my first 400 EX. 2003 model. I expect, like other machines, the stock jetting is a little lean. I'm putting a spark arrestor plate on the stock pipe (removes baffle) and leaving the rest stock. Should I bump the pilot for better cold starting? Maybe bump the main to 150? Also, if I put an outerwares airbox lid, how much further to take the jets? Thanks!
