hey i have owned my 400 ex for jus about 2 years now, when i bought it it had allready been worked quite well, it had hot cam stg2 full hmf exhaust kit and the jetting had been messed with, it had a 170 main and i cant figure out what the pilot is since it is some how scratched along the numbers:confused: , looks like a mess up on instilation, idk dont ask how, but it also has k&n and the lid removed, i was wondering if the jetting is correct, when i first got it i thought it had a ton of power but i am now kind of wishing it had some more. jus wondering if the jetting could b done alil bettr and if i should adjust the pilot screw, bcause it is at the moment all the way in.
