KeiHin, 086A carbs: Purpose of the screw-in plug?

[Qaxe]

My CB750K6 has stock KeiHin, 086A carbs. On the cylinder side, there's a little brass plug. What in the heck is that for? NOS port? ;P No seriously, it seems silly to drill a hole just to put a plug in it. Is that a hole used when these carbs are used on another bike?

Send picture but I am guessing you are talking about the port to hook up the sync gauges.

Is it to close off a fuel passage of the carb ends up moving places in the bank of 4?

I hadn't considered the carb sync ports. Nice save. Dang Honda... thanks for putting that there.

Yes thats the port for syncing.

Yes thats the port for syncing.

Interesting. My 1981 uses a port on the cylinder head.

I had to look at a video for that one. Never saw one like that. Then again, I'm stuck in the 70's, so...
