  • Carb Vacuum and Fuel Lines - 1981 XS1100H

    I am in the process of installing my carb and forgot to write down where the lines go. So far I think this is how it goes:

    Main fuel lines from each petcock (lower nipple on petcock) go straight to the T's between carb units.

    Vacuum lines from each petcock (upper nipple on the petcock) connect to the intake boots on carbs 2 & 3.

    The vacuum line from the ignition connects to the nipple on carb 2

    Please let me know what you think. I have searched the net for a diagram but cannot find one. Thanks, Doug

      Great news. I was worried about the line routing.
