Here's one I don't think I've seen here before. For the second time in about a month, when I re-started my bike today after about an hour lunch break in the middle of my afternoon ride, the idle raced up to about 2,700 RPM and wouldn't settle down. Blipped the throttle a couple of times, still wouldn't drop to its normal 1,100 rpm idle. Rode it anyway thinking with a little riding it would drop back down. 20 minutes and two stop signs later it was still idling at 2,700 RPM. Stopped and turned it off for a couple of minutes, restarted and it was back to normal. I have no idea what caused this or if anybody else has had this experience. But anything that makes me think the throttle might have a mind of its own is a little disconcerting. Is the next step an engine that won't drop below 5,000 RPM??
