First question for you guys is, what exactly does the air fuel screw do? I know it controls the air/fuel mixture. but what does turning the screw in vs. out do? If you turn the screw in, does it restrict the ammount of air entering the jet at idle? Turning the screw out, does that allow more gas into the jet? Please explain. Suspension question, does lowering the clamps on the forks, give better speed stability or better cornering? Say I want to corner better, would I raise the clamps or drop them?
