Dave is in the process of replacing his iacv and would be the third one if succesful, as you may know the iacv is not expensive, just a lot of work to get to.
What may help you in the mean time is using the "engine off" switch on the right handlebar when it has high idle, it resets the iacv position among other things.
It would be interesting to know for us if the high idle is present all the time or starts some time after the engine is warmed up, so starts at 1500, settles at 1050 and then gets " stuck "at 1500 again after some time?
Once the high idle issue appeared, the bike would high idle cold then drop to 1050 when fully warm...normal like (on mine it looked to be right at 1000). Then after a few more miles, it would high idle at 1500 and sometimes spike to 1700. The high idle would continue until shutdown.
The low idle issue (drop to 500, then slow rise to 750-ish) would only happen after bike had been ridden 30+ minutes, often not till it had been ridden a full hour.
Upon any start-up with engine cold the idle would return to normal pattern: high idle at 1500 then down to 1050, after which it was only a matter of time before one or the other would return. After cleaning the TPS, both issues went away for 7-8 rides lasting from 30 minutes to 1.5 hours with two exceptions when idle dipped to 900 momentarily.
I traded it in at this point.
