    Mikuni Jetting

    What is the difference in screw settings if you go down a full 5 points verses 2.5 points with the high speed jets?

    if you are changing jets for some reason, only your spark plugs and throttle response will tell you when the low and high speed screws are set correctly. getting it right takes lotsa time typically

    Understood...the main reason I ask is because my high speed screws are at 0 turns per stock Pro 785 settings but I would rather them be at 1 to 1.5 turns out and I wasn't sure if a 2.5 or 5 point drop in the high speed jets would give me that. I ended up buying both jet sizes anyhow!

    bruce at wet wolf told me that every 2.5 jet size was either an 1/8 or 1/4 turn,was a while back.but 1/8 turn seems to be correct

    it depends how fat they ran from the factory but I would say 5 would be close to 1 turn
