My brand new, 5 days old 2008 Road King Classic is plagued with an intermittent high idle. It has happened twice. Each time was after a 15-20 minute ride and a cool down period of 5-20 minutes. I'd guess about 1800-2000 RPM, but without a tach it is hard to tell. With my son on the back, it will do 15 mph at idle in first gear and almost 30 in second. All with no throttle twist. I can get it to go back to near normal by un-rolling the throttle past the neutral point. Let it go and it's back to high idle! I took it to the dealer after the first event and since it wasn't happening at the time, nothing was done. They did take the time to take it inside the shop and check for any error codes. I don't really feel they were blowing me off; the guy took the time to discuss it with me even though they were buried with other work. Of course, with a 3 day old bike, I kinda expect them to pay attention. I'd rather be keyboarding about how much I enjoy the machine, and I really do. But tomorrow, I'm taking it in and leaving it there. If they say they can't duplicate the problem and left it alone, then I'll leave it there until someone (dealer or HD mothership) does something to fix it. A shrug of the shoulders won't work. I suspect either a squirrelly electronic throttle in the handlebar or a squirrelly temperature sensor on the engine. Anybody seen this symptom on a 2008 with the electronic twist grip? I searched the HDtalking archives, but didn't find anything about 2008 problems. With this post, I have at least organized my thoughts for the visit to the dealer. Any ideers out there?
