    Carb Air Screw Setting?

    Can someone remind me what these should be pre-set to upon carb rebuild for the '83 GS1100E's

    thanks

    2 turns out from lightly seated should be good to get it running, then fine tune from there. Mine are set to 2 1/4 turns out.

      Do you fine-tune yours with a Colortune plug? If not, what do you prefer?

        Not everyone has the 'luxury' of a Colortune plug.

        Some of us just do it the old-fashined way, by listening for highest RPM.

          I don't have a Colortune plug either...The only directions I've found describe adjusting the airjet using one. I have the airjets on my 81 GS550T (32mm) set for 2 1/2 turns out. Could you tell me how you do it the "RPM" way or post a link to directions? thanks!

              I've tuned my carbs by both methods and the highest idle methods produces results that are pretty close to the colortune. The colortune is sort of a PITA because you have to keep shutting the engine off, remove plug, install colortune. I always seem to burn myself using the colortune. I wouldn't buy one again. Probably a more useful tool to have for carb tuning would be a wideband a/f ratio setup.
