  • So the issues drag on :)

    I fixed all of my electrical issues but now my bike idles at 4k. I did the bread tie sync. darn thing just goes right up to 4K and sits there. It spits out little puffs of smoke out of the pod filters here and there also. I checked around the carb boots and everything looks tight so there should be no vac leaks. I'm not really sure where else to go from here.

    The bread tie sync will only get you close, so you can get it running. You're there, but now you have to complete the sync with a real synch tool. And, you should turn down the idle screw, 'cause as you get closer to a good sync, the idle will rise even more. You should do the sync at a low rpm, otherwise the mixture screws won't have any effect.

      once i got the bike going i tried to adjust the idle screw with it turned all of the way in it did not really change the idle. I will be picking up a sync tool.

          The big one that the throttle cable goes to and the screw comes off the back within reach when i pop off the pods. the main idle adjust screw.

              If the idle screw has no effect, you might try checking to make sure you don't have any kinks in the throttle cable, and also make sure the adjustment of the throttle cable at the handlebar isn't holding it open. JAT
              I think I have a loose screw behind the handlebars.

                Randy how low of a rpm? I always thought 1100 rpm.

                  1100 or below, but his is idling at 4000 He's not running on the pilots, so mixture adjustments won't be right.

                          True 4000 is way to much. I was just wondering when you said low idle.

                            my 2 cents worth..

                            again, the bread tie method is only to get it running, if one or two of the carb butterflies are set higher open that would hold a high rpm idle. regardless of where your idle screw is set.

                            check to see if the throttle return stop is even contacting your throttle cam.

                            crack your throttle and let it slap back to idle and watch the "cam" or cable connecter pully thing (i don't know proper name either) and see if it actually hit the end of the idle adjuster.

                            i've had a 2-6K idle problems on bikes after carb work.. it's no biggy i've alway's found it to be a sync problem.

                            good luck
