    Non Vacuum Petcock

    Hi Guys,

    I am running CR29s on this racebike build (77GS750) and need a non - vacuum type petcock to run w/ these CR29s. Can I run this thing on PRI and achieve the same thing or do you think I'll need some after market petcock that is Gravity fed?

    Pingle in Wisconson has a full line of stuff that will work gravity fed on the GS's

      You could run the stock petcock on PRIme.

      I am guessing you are asking this because the CR29s don't have a vacuum port?

      If that is the case, you can put an adapter in your carb sync port in one of your intake boots and run a hose from there to the petcock.
      That would give you the convenience and safety of an automatic petcock (unless that is prohibited by racing rules).

          Gotcha. Thanks guys, I'd love to save the money and not have to buy a Pingle. I'll set it up and keep you posted!
