    Fuel mixture again

    Hello

    A bit confused...... , depending of where I look for information I find that information are oposite .
    In this forum I have read the Left is leaner ( counterclockwise) and in the "user manual" for my Dyna stage-3 kit information says turn right ( clockwise) to lean out...

    Anyone with experience with this to help ?

    My -82 GS1100E is running rich with approx 3 turns out...

    Turn right to lean it out. Turn in till "lightly" seated then turn out, counter clockwise 2 1/2 turns to start with. My 82 1100E engine runs best at 3/4 turns out, your results will probably vary from mine.

      If you KNOW you are at 3 turns out, you can start there. With the engine fully warmed up, turn one of the mixture (pilot) screws in slowly, listening for a drop in engine speed. When you hear it drop, back up about 1/4 turn. Go to the next carb, repeat.

      At that point, I will usually go for a ride to stabilize temperature on the bike (it probably needs to be cooled off), then try the mixture screws again, just to verify they are in the proper postition. You should hear the engine speed drop when you turn the screws about 1/4 turn. You can then turn them back out 1/8 to 1/4 turn.

      Please note that there is a possibility that not all of the screws will be at the same setting. When I did my son's 650, three of the carbs required the screws between 2 1/4 and 2 3/4 turn, but the fourth carb needed almost 4 full turns.
