    81 GS550 fuel gauge supposed to be backlit?

    When I turn my lights on the speedo and tach light up but not the fuel gauge. Is there a light for it that I didn't see when i took the cluster cover off?

      The L model came with a fuel gauge. There should be a bulb on the rear bottom of the center indicator set. It might be burnt out.

      Darn, with so many daily riders it's hard to decide which one to jump on next.;)

          Originally pegged to keep it from moving, I'm sure, but is a feature that is easily restored.

          My son's '81 450T had such a switch, we moved it to his '82 650L.

            Yep. It was hidden behind the bracket on the bottom right side so I couldn't see it when i took the cover off the first time. I had to remove the tach so i could lift the cluster out and get access to it.
            thanks
