    Forget carb clean, need updated carb

    After all the researche I have done today, I beleive I just need to upgrade to a newer Mikuni carb,

    The carb I have, has 3 adjustment screws not 2,

    The jet needle pilot adjustment screw which Mikuni did away with in the early 90's, and a low speed and high speed needle jet adjustment screw,
    the newer SBN44 carbs just have the 2 adjustment screws and the square pump instead of the round one, thus more fuel pressure, and better design,

    I am now in the market for a newer that 87 mukuni SBN-44 carb,

    The jets on the one I have were way off, the low speed jet was 3 turns out the highs were turns out and the middle or pilot jet wasent to bad at 1 complete turn out,
    Until I get an updated carb, does anyone know the correct needle adjustments from the factory???

    I know not too many Kawi 550 guys on this side, but I know the pro uses a SBN44

    and if anyone has a SBN44 for cheap let me know??
