    crazy high idle

    It fires right up after the carb rebuild but my '82 1100 idles at 4K! The idle adjustor screw doesn't seem to make a difference either.

    I just cleaned the carbs and now am running pods with #50 pilots, #122.5 mains, Dynojet rebuild kit with new needles on 4th rung (2nd from bottom), 3 turns out on the air screws and a Star 4-1 header with open pipe. I'm at 5300" elevation (Denver).

    Are my air screws out too far? Needles too high? Pipe too "open"? What do you think?

    Start by shoving the baffle back in, and leave it there. An 1100 is just too loud, you'll make everyone think you're John Bobbitt! Plus, you need some back pressure.

    2nd, your symptoms indicate a lean condition

    Have you bench synced or vacuum synced your carbs? Maybe they're just cranked up too high


    Your needles only affect the carb from about 1/3rd throttle.

    So, intake boots? O rings? Pilot jets clean?

      Make sure your intake boot clamps aren't jammed in the throttle linkage on the carbs. Make sure the cable is on the carb correctly and that the cable isn't bound. If turning the throttle and snapping it back doesn't release the linkage completely there it is one of these problems.

        WHich 1100? E or G? the 50 pilots sound a little large, the main sounds a little small, though you are in the Mile High city...(GO BRONCOS!) so the altitude will help richen up your mix. If you dont have a smaller pilot, Id say dial the screws back a full turn, and see what happens there. Blip your throttle, see what happens. If the motor hangs for a second or two and then comes back down to idle, you're lean, but if its coming back down, dropping below idle then coming back up, you're rich. TO ME, and im not a carb guy, it sounds like you're rich. THe more the bike warms up, the richer it will get, and the idle will slowly start to rise. That is why the book tells you to set your idle screw when the bike is warm...
