    400ex throttle

    So my 04 400exs throttle has been very jerky lately, it is hard to describe but when I'm rolling and I rengage my throttle it jerks and it is not a smooth transition, also if I ever try to pop the clutch in 1st or 2nd gear it bogs (sometimes). When me and my friend jetted it, we had adjusted the wrong fuel/air screw instead I think we messed with the throttle. Any help would be appreciated.

    Put it back like it was, then start from there.
    Find out what the stock settings are and start there.
    Why did you jet it?

    You shouldn't be concentrating on how fast your bike is.
    You should be concentrating on how well you can ride it.
    Never ride over your skill level and Never ride over the abilities of your machine.

    might need adjustment (slightlybent suggested) lubrication or new cable.
