  • Diaphgram and idle adjustment problems

    Hi guys!

    I cleaned my carb and had some problems getting the diaphgram back in place. How i can make sure it is assembled correctly and working? Blow air to see if slide moves, but where? Bike won't start and diaphgram is on the troubleshooting list.

    Another issue is idle adjustment cable. I took it off from the carb, but now i have no clue how to adjust the iddle approximately before starting the bike? Also on the troubleshooting list.



    Thanks

    The diaphragm sits in a groove to keep it in place. You can put a little Vasoline,Dielectric grease or something similar in a couple spots in the groove to hold it in place while replacing the lid if it is not staying in place on it's own. As far as the cable install it then hold the slide up and turn it in until you see the throttle plate behind the slide open just slightly,That will be just after the cable end touches the linkage arm on the side of the carb. You can also just hold the throttle open slightly while trying to start the bike then make the adjustment once it is started. Also make sure you turned the fuel back on. More than one person has forgotten to do that.

      If the diaphragm is a little distorted, put it in the freezer for a bit. When the idle screw touches the throttle wheel, turn it 2.25 turns more & that should start the bike.
