tps evaluating for ii issues

[max]

Hi Max. Great video, thank you. For clarification: Are you suggesting to disconnect the TPS when the high / low idle condition occurs and then seeing if this cures the problem? I will try this the next time the idle condition rears its ugly head and report back. 3 days ago my bike exhibited the worst case of low idle and stalling ever. After 20 minutes of perfect running (around town, slow speeds, stop & go), the low idle suddenly returned. The bike stalled three times, and once it even stalled when shifting from first to second gear (I can force it to keep running by increasing the RPM when stopped at a light, but to me, it sounds like an extremely lean fuel mixture). I turned the bike off with the key, and took out my wife's smart phone to video the condition but when I restarted the bike it returned to running perfectly ( and remained running perfect for the rest of the ride - about 10 more miles, a mixture of stop and go and freeway). Just to let you know, I have discovered that unplugging the EOT sensor when the low idle condition occurs will immediately cure the problem (but I always turn the bike off with the key before unplugging the EOT sensor). I have ridden my bike on multiple occasions with the EOT sensor disconnected and never experiences the low idle / stalling condition.

Thank you, Dave.
You have been very helpful and precise, i have read your comment very carefully several times.

In the past there have been at least two cases where the complete throttle body has been replaced and with 100% sucess.

There have also been other repairs performed with sucess.
as you know i have been working on the eot sensor as well but have not yet found any fault with it, but i know first hand that it is part of the process for the iacv.

My first mission is to prove or disprove the tps, because it is by far the most simplest part to work with, if we can find that unplugging it makes a decisive difference on several bikes we are a step closer, if we find that it makes no difference at all we can concentrate on the next item, but that will probably be beyond some owners to accomplish by themselves.

Think the best way to do in your case is to first make sure the tps can be unplugged by making sure the wiring is long enough to allow this by following the tips in the video so the connector is not damaged by forcing it and stretching the wires.

Then go and ride the bike ( with the camera, great idea ) and wait until the issue happens frequently ( reliably enough ) whilst filming unplug the tps when the engine is running, blip the throttle and see if it has any effect, plug it back in and so on several times.
the reason is that it needs to be repeatable to be proof enough, if it has the desired effect you can go for a short ride and repeat the process, what we want is conclusive evidence.
what you are doing is an a-b test back to back, several times, i'm sure you know what i mean

It may not help at all, but you are the closest to an answer we have so far and i really appreciate your help.
Happy new year;max
