    Here’s our base setting we’ll be using on our Mikuni carb. Obviously all motors are different so treat these as a guide only.

    Main Jet – 260
    Pilot jet – 40
    Needle clip on second slot up from the bottom.
    Needle jet (emulsion tube) – Q-8
    Air screw 1 3/4 turns out.

    to add, I’ve got a vm 32 320-33 model,
    I’ll get it set up on a dyno and compare to a VM34 I’ve got kicking about

    The 32 is running a bit rich as its a work in progress but it runs pretty well

    Main Jet – 185
    Pilot jet – 50
    Needle jet (emulsion tube) 159 – Q-6
    The slide is a 3.0
    needle is a 6DP17
    Needle clip on third slot up from the bottom.
    Air screw 1 3/4 turns out.

    Will be interesting to see the difference between the 34mm and 32mm. Dan barford reckoned he had better results with the 32mm.
