    There are none. Options are run your fuel tap on prime. make a adapter fitting onto the vacum screws or buy a pingel tap that will flow more fuel anyway.

    Manufacturer and distributor of high performance motorcycle parts and accessories for street and drag. Find fuel valves (petcocks), wheel chocks, air shifters, all electric shifter kits, wheelie bars and more here. Products for Yamaha, Harley-Davidson, Kawasaki, Suzuki and Honda available.

      I know this is an old thread, but IS there a vacuum port. Rather difficult to see if the carbs are on the bike.

      It is located on the left side of the number 3 carb about midway up.



      You CAN run the stock petcock...I am doing that, actually. That way, you don't have to run the bike on prime.

      EDIT: I'm an idiot, as the Wiz (OP here) is the very nice fella who found out there was and told me!
