2008 Electronic Throttle

Vibratinharley

I have an 08 Ultra with 2700 miles on it now and it does the same thing. Every 3rd or 4th time I start bike, it races to 2500 and then idles fast at 2000 rpm and after riding for about 2 minutes, it goes away and bike idles fine for the rest of the day. I thought that this was wrong but since it went away after a couple of minutes of riding , I just seem to forget about it till it does it again. I don't want to go back to dealer cause I am sure they will tell me it is fine and will not be able to duplicate condition. Or, maybe they will tell me "THEY ALL DO IT" as I have heard that somewhere before!

Hello everyone,
First post and it did not take me long to find others with the same problem.

I just purchased an 08 SG and had around 350 miles when I also noticed the engine revving to around 2000 rpm when stopped.

I had been riding the bike earlier in the day without issue and the air temp was around 70. I was on my way to work and I noticed when I would stop in traffic with the clutch pulled in the engine would idle at 2000 rpm. I shifted the bike in neutral and it still idled high even with the clutch out. I decided to pull into a parking lot and I turned the RUN/OFF switch to OFF and then turned the ignition switch to OFF.
I turned the ignition switch on and flipped the switch to RUN and started the motorcycle. The throttle turned freely but it still was idling to high. I could turn the throttle forward and it would come down a few rpms but would climb back up if released or when I turn it to increase the rpms.
For those who are not familiar with the new Electronic Throttle Control the grip actually turns forward slightly. This is one way how you can cancel the cruise control.

I continued on to work and it was still doing this and I even tried to turn it off and on one more time in the parking lot before entering work but it continued.

8 hours later it ran fine. it was idling at around 1000 rpms when stopped at lights. The temp was in the 40s.

I just want to update that I rode yesterday for several miles and stopped and started without issue.

Now I am beginning to wonder if it is something that I might have done not being familiar with the (ETC) Electronic Throttle Control.

It would be possible that I turned the Off/Run switch to the OFF position before the RPMs reached the lowest level.
From what I am reading this would keep the higher throttle position in memory causing it to run higher rpms on the next start.

I also may have turned the ignition switch to ON prior to starting the bike when I was backing it out of the garage.
In doing so I could have twisted the throttle slightly before pushing the start button.

I am now going to be more aware of what I am doing when moving, starting and stopping the bike and try not to move the throttle in any way.

My 08 FLHX is also equipped with (EITMS) Engine Idle Management System. Once again this is a new feature that I was not familiar with.
With the ignition switch on and you ROLL OFF the throttle past the neutral position and hold it for longer then 3 seconds the cruise indicator lamp will flash GREEN showing EITMS is enabled or flash RED showing disabled.

I have had this happen a few times since the 1000 mile service. When mine starts to idle at 2000 and wont drop i shutthe bike off,turn off radio. I then turn the the ignition on then off wait 10 seconds repeat 4 times. Bike starts and idles great after that. I also have gotten into the habit of not starting the bike with the radio on.

This has worked everytime to drop idle

yea, i had the same thing on my 08 roadking. there is a simple quick reset. turn your ignition on with your run switch off. roll the throttle wide open slowly 3 times. turn your ignition off. turn your run switch on, then your ignition on and start your bike. your local dealer should know this. as far as i know there is no recall for this problem yet but most likely there will be.

Same issue on my 08 SG but only once so far.

I was told by my salesman that if you roll the throttle too far forward (past roll off) it can cause the fly by wire to malfunction. I simply turned off all electronics, and with the bike off, turned the ignition on and off 4 times without starting it. On the 5th turn-on...started it. Problem solved and hasn't returned since.

I remember exactally when I rolled the throttle too far forward. I was turning around in a gravel driveway that was slanted. I know this is what caused the problem and I'm glad Marley had covered it with me at time of delivery.

It works...trust me.

08 RK Classic with 1700 miles on it in 3 months . Never a problem w/ the idle . My owners manuel also has the directions to enable/disable the EITMS controll on page 140.

I have a 2008 EG that did the high idle thing. I read I thought on this forum how to fix and how to keep it from happening again. What I read was to turn your ignition on for 10 seconds or wait until the fuel priming stops then turn it off. Do this 4 times to reset the idle. The key here now is to after your ride not to turn your bike off until it idles down because the bike will remember where it was idling at shut down. I started waiting for the engine to idle down before shutting down and haven't had a problem since...

I have an 08 Ultra and the same thing has happened to me several times. The dealer told me that the throttle remembers the last position when you turned off the bike and remembers that position as neutral. He said to keep you hand off the throttle when you turn off the bike. I have done that and the problem still occurs.

I don't know about keeping your hand off the throttle when you shut the bike down...but...I've found that if you don't touch the throttle at all when you start the bike, all seems to work fine. It seems that even just resting your hand on the throttle at start can cause the bke to idle a bit high.
