I noticed as I was taking apart the carbs that a nozzle seems to be broken off the cap of the right-hand carb. Before I took it apart for a cleaning and a sync, the bike ran half-decent. There were no hoses attached to this hole, thus it can't be critically important. I can't find any good pics of the top of a GSF carb, nor can I find a part number for this plastic piece. If anyone could offer some insight, it would be much appreciated :icon_confused:

Take a look at this thread. It might be answering the same question.

Ah, thanks for that
Hello,
There are two nozzles on each plastic cover. One nozzle should be closed and the other connected to a hose form the solenoid valve. This is true for both plastic covers.
If its the open one that is broken, I think it is better to block it (you could also block the left one, or unwire the valve)
The hole assembly (Valve-plastic cover) controls the piston valve lift around 4-6K rpm.
