OK, newbie questions never stop, even three years in. On the second carb in from the left, there is a hose fitting (looks like brass) that exits up, kind of left and rearward.
what does this do? I'm running a non-vacuum non-OEM petcock, so is this yet another vacuum fitting for me to cap? I finally blocked off the one on the next carb over and it gave me a hell of a performance boost over when I pulled the bike out of the PO's garage sale.
Gimme a shout and hep me out. Thanks in advance.:silly:

Are these VM26 carbs we're talking about here?
If so, there should be two of these. One on #2, and one on #4. They are NOT vacuum ports, but are vents. You should run a hose from these two ports back into the area under the seat, above the airbox.
Here's a good reference for you:

Oh, yeah. And welcome to KZR!

they have to be vented to the atmosphere in order for the carb's to work don't cap them off.

Thanks, Skyman. Excellent link for my needs. So far, so good. I can add some vent lines. My main concern was that it need not be capped.
Back to work.

Some carb sets do include a 5th vacuum nipple for a hose to the petcock. Such nipple closely resembles the 2 floatbowl vent nipples (which aren't capped, and exit to open air, usually by tubes routed under the seat or under the bike).
Where a manual petcock is fitted, the 5th vacuum nipple isn't used, and should be capped (same as the other 4 vacuum nipples).
See example below.
Good Luck!
