    Kawasaki 750 carb tuning 96 SXI and up

    I am looking for some advice:

    96' 750 sxi (mikunu I's) stock except no choke butterflies in the carbs and R&D timing advance.

    It has 19 psi pop off on each carb (black springs 2.0 N&S).

    I cannot find pop off specs and with the choke butterflies removed the vacuum will be less...


    I am trying to determine what jets to use and if I need to adjust my pop off pressure.

    Jets I have:

    main 147.5 (stock) & 150
    low 67.5 (stock) & 70

    Please reply with any recommendations - what jets to install & if pop off should be changed?


    Thank you

    What flame arrestors do you have? Also, I think it is dangerous to run the timing advance plate with a BP CDI. The advance plate is made for the SP CDI that has a lower timing curve.

    I don't know that removing the chokes will mandate a jetting change. I would start with stock settings since the rest of the ski is stock.

    Have you removed the rubber trumpets from the airbox? If not, do it. Removing the trumpets makes the stock airbox as good as aftermarket for performance and does a better job a keeping water out. It will also be correct for your popoff. If you dont remove them, I think you will need to raise the popoff a tad. That is pretty much the setup I am running, except a ported SP cylinder
