    1980 gs550 petcock

    i've got a 1980 gs550 which i bought at the local Harley dealer(haha) and i need to know about the petcock on which the handle is broken off. What remains is a little slot like a standard screw slot. I can turn it with a small screwdriver, but i need to know which way to turn it (clockwise or opposite)' in order to change it from the 'on' position to the 'reserve' position. thanks for helping

    Clockwise would be reserve - counterclockwise would be prime

      The petcock lever isn't broken. That's how they were made in '80, just a slot.

      Also known as "The dreaded '80 petcock".

        Sry., unable to help as it doesn't require DUCT TAPE and is too advanced for me.

          Most models in 1980 did not have a reserve position, not sure about the 550.
          Just ON and PRIme.
          Really a poorly designed petcock.

            Concerning the "dreaded" 80 petcock. I was going to buy one last night on ebay, for $49, but it looked exactly like the original factory one. Should I buy a different, aftermarket one? 1980 550L. Thanks.

              Why did you post this? You are wasting bandwidth. This is the Technical Forum, not Off Topic.
