Well I put my bike away for the winter and when I de winterized it, fresh charge and new fuel, the bike revs at 3100 RPMs. Not sure what the problem. I have not done anything to bike. It is 100% stock. | ||

Sounds like intake seals. | ||

Or some animal/insect has built a nest in there over the winter and the throttle is not returning all the way back to the stop. Stranger things have happened. If you've got the idle adjust cable installed (I think it was a service bulletin) you may want to try adjusting that. Maybe someone walked by and twisted it for you. | ||

Yikes! Intake seals are a definite suspect. Since it happened on 'wake up', I would pull the airbox and make sure the butterfly is closing completely. Check the throttle cables and butterfly shaft. If that is all good,the intake seals would be next on my list. Hope this helps, Dave | ||

I am also thinking intake seals. The bike ran flawless when I put it away and no one touched it. The outer cable cam and inner butterfly are working just fine. the throttle return is returning as it should. It does appear to be an air leak. Is there w way to narrow down where the leak is coming from? I have the air filter off | ||

Just replace the manifold seals with the nice soft blue ones. Then make sure your throttle stop screw on top of the throttle body is backed out far enough to let the butterfly close. 3100 rpm is a lot, you might have an issue with the butterfly's shaft. | ||

No way an intake leak could cause that level of high idle. Look elsewhere. You need to visually inspect the throttle body by removing the plastics. Also do a TPS reset if you have the software. Better done with a warm engine but you can tweak the idle speed after you address your main issue. Keep us posted. | ||
| Hootowl |
I think that's probably right. It has to be getting fuel to idle that high. | ||
| Akbuell |
If you have access to ECMSpy, check and see what your TPS setting is. Should be somewhere in the 5% or 5.1ish degrees. Check in the B.R.A.N. for a Badwebber nearby who can help, if you don't have it. A bad intake seal will/can cause a high idle, but usually not over 2k RPM. Or, the idle 'hangs' up at throttle close, before returning to normal. Hence, the feeling here that the issue is mechanical, before a seal issue. One wild guess, since the air box is off: Hold the throttle wide open, then turn the key on for 2 sec, then off for 2 sec. Repeat 5 times. Take a strong light, and a mirror, and hold the throttle open and look in the intake manifold. It should be dry. If you have fuel, perhaps (big maybe) one of the fuel injectors is stuck open, causing the high idle. Hope this helps, Dave | ||

Welll I turned down the idle scew (cable) and problem fixed. Not sure how the idle raised itself, maybe vibrations while riding.but it appears to have been fised with a simple turn of the screw(Allen) | ||
| Hootowl |
Are you sure no one gave it a turn for you?  Kids playing, etc.? | ||
| Akbuell |
Glad it was a simple fix. Garage Gremlins strike Again! ! ! | ||

Perhaps a crumb of something got between the stop screw and the throttle. I used to have that problem on my various off-road bikes. Sometimes it doesn't take much of a shim to make the bike behave weird. | ||

You should be able to turn the little knurled knob at the end of the cable with your fingers. You may need to lubricate the idle screw/spring, or reroute the cable if you had to use an allen to adjust the idle. |
