Update: I removed the entire air cleaner housing to access the IACV (Idle Air Control Valve), and I tested it per the manual. It functions correctly.

I have examined the various air hoses. All appear in good condition with no cracking or lose connections.

The Air Control Valve, which sits atop the upper air cleaner housing, functions also.

I am still experiencing high idle at 2,000 RPM.

On occasion, idle will decrease say after turning off the bike and restarting; however, twisting the throttle, and releasing causes the 2,000 rpm again.

After changing the filter and testing the IACV and 3 other sensors, and hoses, I am at a loss as how to resolve my 2,000rom idle.

I also adjusted the throttle system per the manual, and fuel system inspection and secondary air as all part of the troubleshooting per the manual.

I took the Red Enchantress by my local bike shop (not a Honda dealership), and we discussed what I had done. The fellow said that it sounded like I had done more than what was needed to resolve the problem. The owner admitted that he would be willing to work on the bike, but admitted that he likely would not succeed or easily being unfamiliar with it. That said, he recommended that invite the bullet and take my bike to the more expensive dealer (hour rate) to save money. 🤦‍♂️

Even this time of year, they are three weeks out, so I have an appointment to take her and drop her off. In the meantime, I will tolerate the idle and continue to ride.

Last week there were two days that was warm enough to go for a ride, so the wife unit one each took it to Hagerstown to do a little Christmas shopping...…. at times it idled at 2k and others at 1k. All at normal operating temperature...…… and after having driven on 45 mph roads and freeway.

Bob, I don't remember it idling at 2K after being up to temp while sitting at stop lights...…..

Since you said it'll come back up to 2,000 RPM after you give it throttle, have you checked to be sure the throttle is returning all the way back? I'm pretty sure you have, but just wanted to make sure nothing simple was getting overlooked since I didn't see any mention of that end of things in the earlier posts.

I have a date this Saturday with the dealer. I was unable to resolve it, and my local general bike shop recommended the dealer.

As soon as my high idle (2 - 2.3k) is resolved, I'll report back.

So this is what happened yesterday. Bike wasn’t driven for about 4 weeks. It’s been parked in a cold garage hooked on battery tender . It took couple of more cranks than normal for the bike to start, after starting the bike idle was at 2000 rpm. I left it to worm up for about 10 minutes ( outside temperature 42F ) , after worm up the idle went down to about 1000 rpm. Went for a ride for about 5-6 miles, stoping on stop signs and lights the rpms ware between 1200-1300 rpm , and gradually dropping down longer I was sitting stoped. Stopped at a gas station filled the gas tank with premium and added “Stabil” in the fuel. Then took the long way back to the garage, about 10-11 miles with only one stoping on stop light( rpm 1000). When finally parked the bike the rpm was steady at 1000 rpm.

Just a thought.
Since premium (92 PON) gas is NOT needed in this engine... normally (designed for regular)... and the bike computer has to adjust the spark and ignition timing to burn premium gas...
Is the OP using premium fuel? If so, is it possible that the specific blend of premium being used is at fault for the bike computer holding the idle high?
Just a thought.

Update:

Bike has been at the local Honda dealership since the 14th.

They have NO clue either as to what is causing the fast idle. They are awaiting resolution from Honda.

The tech remarked that he suspects that Honda is uncertain to the cause.

Thanks for keeping us informed on this issue! But I gotta wonder... does Honda even care?
