    VM carburetor air/mixture screws: in = leaner, out = richer??

    Is that the way of these screws or is it opposit? I can't seem to find the answer anywhere. Some have said one way, some the other. Is it the same on the CV carbs? I've got a 79 GS850. Thanks.

    Lefty-loosey, righty-tighty!

    Mr. ironsheik,

    Turn counter-clockwise to richen up your fuel/air mix.

    Thank you for your indulgence,

      Just wondering if it would be the same for my Mikuni's on my 1980 750L?
      Was running lean a bit and just turned them 1/2 turn counterclockwise. Did I just fix it or fukc it?

        Which screw? There are two separate screws on your VM carbs.
        The pilot fuel screw, underneath, is turned in (clockwise) to lean the pilot circuit mixture and out to richen.
        The side air screw, is turned in to richen and out to lean. It admits air only so it's obvious how it functions. It should be tuned using the "highest rpm method", always.
        And on the seventh day,after resting from all that he had done,God went for a ride on his GS!
        Upon seeing that it was good, he went out again on his ZX14! But just a little bit faster!
