I dig what you're writing about.
But this will be no answer to the question, why my CB always had good and low idle revs through all seasons of the year for a long time, after it was warmend and than all of sudden the idle problem came into play during last summer and stayed. I ride the machine long enough on trips, so it should be warm enough. But there is a lot of electronics working together and lots of data flying around, who knows how it is connected and how some slightest bugs in the world of bits and codes can lead to irritations? I' m not an engineer, but I do my best to work on some tips, to keep this bugs out and let the honda run normal again or what I consider to be normal. This high rev thing isn't it with a warm motor.

Saw on the following thread that it appears that Honda has new ECU mapping software to address problem. Post #107

I realize that your issue may be different from mine, just wanted to add my experience.

Hi John, if I remember right, your bike was under warranty at the time you had the IACV motor replaced. Do know what the cost would have been if you had to pay for it? Part and labor?

I also, along with others have only had the problem after riding thru town for 20-30mim, at low revs. At very low revs the alternator may not be producing enough power to keep the battery topped up enough and it throws up a problem.
Just Sayin....

I just changed my battery and had no issues prior to that.

In fact, the period when I had the stalling issue was when my battery was in top notch conditions.

People seem so desperate to find a solution for this they tend to make correlations between the idle issues and new events such as a new battery being replaced.

I dont believe for one bit the battery has anything to do with these issues.

I didn't know, or didn't remember, that part of your experience, thanks for sharing that, good to know.

Hi pdedse, your memory serves you correctly. I don't have the invoice in front of me, but I believe the total for the IACV work was north of a grand, parts and labor. I believe they replaced the entire assembly, leading to the high cost.

Sad to think about my bike possibly needing that, but good to know. Thanks.

Dave, I found your post Googling for EOT resistance values.
Difficult to find much other than this forum.

At what temperature were the new and old sensors measured for resistance?
At what temperature is the spec for 2.4 - 2.9 K ohms?

Mine has never done any of this so i wonder if it is because i never ride it in cold weather and seldom even have cold weather. always idles at 1100
