Well I cleaned the hardware with WD-40 and am still getting the problem. Also noticed the other day that it is missing occassionally around 60-70 mph which is also followed by a high idle. I can pull the clutch, hit the kill switch and restart while rolling and the problem clears immediately only to come back 5-10 miles down the road.
Here's another thought, would a clogged fuel filter possibly cause this problem? A couple of years ago I didn't close the fuel cap all the way and the vent was not functioning. The bike started running rough, missing, etc and I recall that it also was doing the high idle thing. I pressed on the fuel cap and hear a loud hiss like air was being sucked into the tank. The bike ran fine after that. Do a fuel system problem sound like a plausible reason for a high idle? especially after killing the engine and restarting?
