Stop engine and restart doesn't solve it. unplug and plug back EOT then she return to normal (I had my finger burned trying to do this).

Trying to find the cause online and end up reading 61 pages in this tread for the past 3 days (not giving up yet, will continue again). From what I have read, it seems like this problems can be from multiple fault, but all giving same symptom. hence some method works while some don't. Anyway, i updated the spreadsheet with my details (I deleted some lines which are empty without any data. i double triple check and its all empty row. hope i didn't delete the wrong thing.). hoping others can find their solutions.

My friend's CB have the idling too slow and engine stalled problem as well before this, but he solved his by spraying something into throttle body, to clean it he say...

zirconxi, as one who had high/low idle issue, sorry to hear your bike is acting up.

I think it was SportsterDoc who came up with a trouble-shooting list of where to start from simple to more complex possible causes--I searched but couldn't find it. Dave in San Diego outlines the more complex fix--the IACV.

did I miss something? but there isn't a fix, still remains a mystery what the cause is, let alone what the solution is

My low idling stalling was not fixed, but resolved by replacing the whole throttle body under warranty luckily.
Thats no fix, thats guessing and hoping for the best, and it worked out.

I doubt the IACV is the cause and the solution for the idling issues.

As of today, Honda has not recognized it as a big enough issue to organize a recall on particular models of the CB1100.

I think there are multiple causes thus multiple solutions. All these are different problems but will show the same symptom. Some are electronics/electrical (Sensors, contacts, wiring, battery), some software (corrupt data, firmware corrupt, error in program), some hardware (IACV, Throttle body, dirt, sticky pin, electrical motor, vacuum leak), some mixture of a few, some other unknown. I think Honda wouldn't issue a recall if there is not a specific design fault that cause the same problem.

One thing is know for sure, nobody knows anything really.

Again, all speculation from our side.
