    JD jetting initial set-up

    by chirocrf » Mon Jan 11, 2010 1:39 pm

    I recently purchased a 2007 250x that has a JD jetting kit. I have the extra jets and needles. Does the kit come with a list or chart of proposed jetting for initial set-up and different conditions?

    It comes with an instruction sheet, what is your elevation? What other mods do you have? Is the air box cut? Exhaust opened up?

    I ride in the Kansas City area around 800ft. The air box is cut open and the baffle has been drilled. The current jetting is 155 main, 42 pilot, fuel screw 2 turns out and with the red needle..not sure the clip position, haven't looked yet. The bike runs well but I ride in Colorado and Utah as well so I was hoping to estimate jetting set-up for those areas.
