  • Vacuum Lines

    Just want to be sure here, I have a 79 standard with vacuum petcocks. Anyway does the vacuum line from carb 2 go to the petcock that carb 2 is recieving fuel from or the other one? The same question for carb 3. the way i have everything routed now is carb1&2 get fuel and supply vacuum to the right side petcock(opposite side of the bike), and vice versa for 3&4. is this right? I am pretty sure it does not matter which petcock delivers fuel to which carbs, but does it matter which vacuum line connects to which petcock?Thanks for any replies.

      Right now it is kinda rough, I justy got it runnin after it sat outside for ten years. I attemted the bread tie syncronization and it was idling at 5k rpms, I havent readjusted the butterflies yet, I just wanted to make sure it was hooked up right.

        Hey Steve,

        It doesn't matter which hose goes to which petcock, AS LONG AS IT'S THE INTAKE MANIFOLD port, and not the actual metal port on the #2 carb body!! That one is for the Vacuum advance. Your description was a little vague, just wanted to make sure you knew this!

          I appreciate it Top Cat , I have them all hooked up correctly then. Just wanted to make sure that the Vac line from 2 (not carb body)didnt have to go to the same petcock that it was recieving fuel from.Thats all. Thanks
