ATS and VFC are not the cause. IAV might I have read where a bearing has fallen out or the screw is not seating right.

The gear indicator works by looking at the MPH vs. RPM. If that is indicating improperly, maybe the clutch is responsible. I can make my gear indicator misbehave if I slip the clutch while riding.

Clutch freeplay then?... You got plenty freeplay at the hand lever?

@TNXR this is not a case of denial that my mods are causing this issue. This is a case of having a fairly good idea of how these components function and knowing that the IAV is the only if the 3 than will have any effect on idle speed, and that it by itself would not be able to determine whether the bike is in gear. In conjunction with he IAC which operates as part of the idle management, I could see how maybe, through some arcane arrangement of interrelated telemetry, it could be responsible, although I've never heard of this. Tearing everything out and going back to stock is a lot of bad troubleshooting. If anything I'll start with the IAV because I want to replace the boots on the vacuum lines anyway. I'm not going to just throw shit at the wall to see what sticks. We're not there yet.
@philmonger it's not lost on me that perhaps my clutch is getting tired. 30k on it. Might be getting time. @Motorbikerx this goes along with Phil's statement, I adjusted the clutch, dead cold in the AM, no change in behavior. I was probably overdue and had very little freeplay.
@visionjohnny thanks for the tip. That's the kind info I was hoping to find.

Still doesn't explain how any of this could be dependent on gear position though.

As long as your confident that it is not your mods then go at it and good luck.

30k is nothing on our clutches mines well over 60K miles now and I'm dragracing it the last 10k
Clutch either slips or holds.

I'll add this point on clutch freeplay...its all well and good to set it cold but check it hot.
Easy enough to pull the cable away from its lever perch till it moves the lever to its limit.
while taught ,actuate the lever. It pulls the cable back onto its perch.
There should be around 1/16"--1/8" gap in this area hot as proof the clutch isnt riding on itelf.
Better to have a bit more freeplay than not enough in my experience cos it'll get less when it heats up.

Only takes a second to check, same with hot drivebelt, a poke with your finger to prove it has a little movement when hot.

no tools needed, just your hands..

UPDATE

Couple weeks ago I just pulled the IAV and replaced the vacuum boots and lines. That seems to have calmed down the weird idle...mostly. I feel there is still something misbehaving here somewhere. I'm using @RICZ settings in the VFC and the bike actually seems to run a lot better, but I'm thinking I'll go ahead and and get the bike to a tuner since one has sprung up in Boise.

As for the misbehaving gear indicator, I think I may have tracked that down the the clutch interlock switch on the handlebars. It is definitely acting up. I'll probably leave it alone for now and start in neutral if I have to. Bike usually gets parked in neutral anyway. Feel like that part is gonna be tricky to find.

Thanks for everyone's suggestions.

Those switches are expensive for some reason.

try a cheap one off Ebay first maybe before spending a crapload on a new one.

Thanks @Kurbs

I had not even begun shopping for one yet, so you saved me some legwork.

If nothing else is amiss then an IAV makes a bike with mods more tuneable at idle.
Mine gives me no problems
I know how to adjust it.
Follow lloydz directions.
