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.

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!Last edited by Guest; 03-31-2013, 07:10 PM.Comment
