Discovered a large, knurled adjustment screw going into my IAC that isn't shown on any of the mfr's parts diagrams. Anybody know what it is?

That's part of a Lloydz Motorworks IAC valve. You can adjust it to eliminate exhaust popping (from deceleration)

If one has decel popping, do you turn the screw in (clockwise) or out? I'm asking for a very close friend. :angel

Meant to delete. Yes, found the ad on the Lloyd's page. I have a lot of backfiring, not decel pop. Maybe that's why.
If it's backfiring when you first open throttle, it's prob lean & need to close it a little, or could be any number of other things.

I hate to be the bearer of bad news, but I do not have the valve myself, so I do not know the particulars. Lo siento, señor

Did that cure any decel popping, if you had it to begin with?

I've had that IAV on my Cross Country for years. It doesn't work. The only thing that it has ever done on my bike was lower the idle as you screw the valve in. I fought the backfiring forever. Did all the "fixes" that everyone tells you to do (exhaust header gaskets, rubber boots, etc). I have basically everything short of a big bore kit that Lloydz sells on my XC. The IAV is the only product that I think is worthless.

In the end the only thing that fixed the backfiring or decel popping was getting the bike dyno tuned by a tuner who knows what he is doing with Victory motorcycles. It needs to be a tuner experienced with Victory motorcycles who understands how to remove the backfiring. IIRC it's caused from a lean condition when you close the throttle. So they have to go into the power commander and add fuel at the throttle positions where the back firing typically happens.

Now the bike will barely run, except at 3k. Won't idle, surges wildly at low rpms a blows farts at everybody. I'm thinking fuel pump or tps.

Looking at this thread, it appears that it ran enough to ride it prior to tinkering with the IAV. A battery will not fix that.
Is that because IAVs are 110 volt ? :laugh

maybe some help. Remember this only works for idle control
