hello, i am helping a friend try and work out his jetting on his 1998 yz400f. the problem is when you wick the throttle, the bike bogs, and sometimes dies. i took apart the carb, made sure everything is clean, and it didn't make a difference. i have the manual, and it doesnt really go into how to adjust the accelerator pump. right now, it doesn't look like there is much movement at the pump. we ride between 6,000 and 9000ft. main jet right now is 168, 145idle, and 165 start jet.
any jetting tips would be appriciated, or how to adjust the accelrator pump. thanks
joe
