My problem started after I spent many mornings riding at slow speed in a parking lot, slipping the clutch and using the rear brake to go slow while I practiced U-turns and circles.Each day I would do this for about half an hour. I am not sure how long( a couple of weeks, maybe a month) it was after I started doing this before the slow idle and then the fast idle started, but it might well have been related to the constant clutch pressure.
There seem to be so many factors involved that complicate the whole problem.
I have stopped the slow-ride practice, just in case.
Again- correlation /= causation.
Low speed using the clutch just induced a situation with low speeds...does NOT mean the clutch switch itself is any fault / cause.
The ECU is the brain- it looks at inputs then outputs based on that.
If it sees the idle drop- it doesn't care why- doesn't care about the clutch any more than it would if you were dragging the back brake. All it cares is- RPM should be higher-and it TRIES to adjust both air and fuel to compensate. There are probably a LOT of parts involved- idle control valve, intake air temp, airbox manifold pressure, throttle angle, heck- even oil temp...maybe more.. unplug any of those could make a difference at that moment- without meaning that part was the failure reason.
It is entirely possible the original IACV design may have had some issues- but it is just as likely and seems to be the case that the parameters of feedback range before things go south was not appropriate either.
I work in a completely unrelated field- other than the fact that my job entails complex arrays of computers, actuators, and sensors on a WIDE variety of diverse products.
I have seen first hand more times than I can count, pushed out on TSB (technical service bulletins)- new software revisions to 'adjust' (loosen range / specs) that the computer is looking at before fault.
And @cormanus- 'friendly' is an opinion. Some people get upset at facts- where others understand reality and think nothing of it. I'm more of a suck it up buttercup kinda guy. I'm more than willing to help people- it's up to them to listen.
You say - " It would be friendlier if you explained how it is you and others here know the clutch sensor is not the issue nor related to it."
Yet- you discount that we took our time to give advice at all. It's not up to you to judge and comment on how YOU think we should give it. Especially when you didn't contribute to the solution.
None of us are employed here to teach a class. We aren't getting paid. We do it all for the love of the bike and the community. People are free to do what they want... some good, some bad.
Heck- how many people coming her to ask for help have even started with class 101 and bought a repair manual for this bike?
I'll 100% admit I am more mechanical than electronic- but if Max or Popgun gives me advice- I'll read it, chose my path and go on- I don't come back and comment- judge their personality...
