Really high idle

[SportsterDoc]

Thank you Doc, you know WAY more about these electronic components than I do.

Probably not, as most of the info is from the Honda service manual, thanks to Popgun. I just did some summarization.
There are several on this forum (Popgun and Max for example) with much more electronic background than I.
My dad trained me to be an industrial/commercial electrician and an industrial electric motor rewinder, but that was long before the electronic age.
Before I got into automation, I did have experience with stepper motors...helpful understanding the IACV.
My experience operating Cycle Tuning Unlimited (late 70s - early 80s), was mainly ignition points/timing/dwell and carbs...nothing electronic, other than converting my 1976 CB750F from dual points to a Martek 440.

The point in this trip down memory lane, is that access to a FSM can solve most problems. The benefit of this forum is being able to share experiences, as you and several others regarding the IACV have done.

I no longer have the CB, but this remains one of my two favorite forums.
