I have an 06 400ex
Air box lid removed, KN w/outwear, spark arrestor removed, WB CDI rev box, one heat range colder plug, Sparks timing advance...
Im at about 2500 feet, im running a 160 main jet with needle on middle(3rd) groove... air/fuel screw is 3.5 turns out...
I had a 165 in with this setting and it was runnin pretty rich. In end of 4th into 5th a 400ex with stock intake, timing advance and CDI box, arrestor removed and with a heavier rider was pullin on me hard in 5th.... I switched to 160 and havent run him yet.. btw, he hasnt jetted at all...
what do you think??
im thinking i may play with the air fuel screw, ill do a plug check but i dont think i should have to go to 155 main....
