1982 GS 550L - When I tighten the air screws, does that make it leaner or richer? Also does this actually control the air or the fuel? thanks in advance

That is the only screw on this year of bike. Turning right leans it and turn left riches. terrylee -

I call this the idle mixture screw. Fuel is pulled from the main jet and diverted to the pilot jet because the main is blocked by the jet needle.
Air from the pilot air jet (on the filter side of carb. the jet you can remove) mixes with the fuel and goes through the idle mixture screw. This is premixed (fuel/air). The screw controlls how much fuel/air is metered during idle.
They are set lean at the factory. I do the highest RPM method by setting each idle mixture screw so the engine idles the highest. (self explanatory)
You'll need an temp tank to do this and a long screwdriver. Get a sync tool and to your carbs while your at it.1983 GS 1100E w/ 1230 kit, .340 lift Web Cams, Ape heavy duty valve springs, 83 1100 head with 1.5mm oversized SS intake valves, 1150 crank, Vance and Hines 1150 SuperHub, Star Racing high volume oil pump gears, 36mm carebs Dynojet stage 3 jet kit, Posplayr's SSPB, Progressive rear shocks and fork springs, Dyna 2000, Dynatek green coils and Vance & Hines 4-1 exhaust.

I've often wondered who was in that car parked across the street at all odd hours.
