Just wondering what you guys have for jetting on your 400's with a X-6. Lid or no lid. Main, pilot, turns on fuel screw. Thanks!

right now it is about 50 degrees outside and i live about 625 feet above sea level. i have a 10.8:1 86mm ross piston, stage 2 cam, uni filter, air box lid on, x-6, etc. and here is my jetting using KEIHIN jets:

main: 158
pilot: 42
needle location: clip in 4th position
fuel skrew: 2 turns out

jetting changes with your mods, as the temp changes, or if you change altitude of riding areas. humidity and other factors also come in to play. with the airbox lid off, you will probally want to go up one or two sizes on the main for sure.
