    I have 1974 400CR with a 36mm Mikuni running a little hot plug doesnt look super lean. Does anyone have a baseline jetting for the 36 mm Mikuni and a 74 400? Heres whats currently in it. Its what was in it when I bought it from a fellow 400 owner. Any suggestions? Is this in the ball park? Searched the site for what info I could already. Thanks

    Yes!
    Main jet is too small, closer to 400 is needed.
