I had the opposite problem - after warmup, idle speed went to 0. But everything seems good, now. I have successfuly gone through the TPS adjustment procedure as spelled out by the latest version of the GS-911 software. The procedure is easy; getting access to the throttle position actuator and sensor takes awhile, though. First, run the first part of the TPS Adjustment test to be sure the potentiometer needs to be adjusted. If the upper bar is red, you'll need to get to the throttle body rail to proceed.
In a nutshell, you have to get to the throttle bodies by removing the black and chrome "wing covers", upper left and right tupperware, stingray, seat support, and fuel tank. Try to remember where all of the plugs go. If you're organized and have done this before, it takes about 90 minutes. You can then run the second part of the test, which requires removing the throttle position actuator - the unit that looks like a small windshield washer motor on the side of the throttle body rail. If this step fails (upper bar is red), you'll need to adjust the potentiometer.
So loosen the clamps securing the intake tubes to the airbox and pull the airbox to expose the throttle bodies. Then, loosen the left radiator by pulling the mounting clips and angling it forward a couple of inches, and remove the bolts holding the injector rail so that you can pull the injectors out. No need to disconnect anything. Finally, loosen the bottom clamps securing the throttle bodies to the head and slide the throttle bodies up and forward to expose the potentiometer on the back end of the throttle body rail. Loosen the two screws enough to turn the pot to center the upper bar in the GS-911 software, and follow the directions onscreen to lock it down and verify. They will also direct you to remount the actuator and re-test.
You're done! All you have to do now is remount the throttle body rail, injector rail, airbox, radiator, gas tank, seat brace, and tupperware!
Yes, this'll keep you busy for awhile. But the new GS-911 software finally makes it possible to do something that we would have had to pay a dealer through the nose to do for us if we're out of warranty. The bike's idling great now, with smooth response right from idle. But check your O2 sensor first - it's a lot easier to get to!

One of the sensor inputs to the motronics is engine temperature. I wonder if that is causing your headache. My idle is running high and I'm seeing a GS911 fault code for the TPS. I'm leaning towards bringing it to the dealership for service. I just don't want to get her stripped down only to find I can't resolve the problem.
