Default 08 Ultra Classic Idle problem

I just picked up a 105th Ultra Classic. As I was riding it home, I noticed that the bike was running at high rpm. At the stop signs, the bike was running at 2000 rpm. If I turn the throttle away from me then the idle goes down to 1000 rpm. So how do I adjust the idle down to 1000 rpm on throttle by wire model?
thanks in advance.

Mine did the same thing until I got up to around 80 miles or so then decided to idle just fine. Glad to hear someone else talk about the same thing.

Fuel Injection means you don't have an idle screw to adjust the idle with. All idle adjustment is done my way of map downloads. Strictly computer controlled.

So yours did not run at higher rpm like mine? I have total 90 miles on mine.
Earlier post indicated that after 80 miles, it went down. Did he meant after total 80 miles of travel or 80 mph?
What is your current idle speed?

Thx

Take it to the dealer and jump up and down and scream at them until they fix it.[sm=massbounce.gif]

That is the final solution. Still I have wait till Tuesday. Good thing I still got my trusty FJR1300.
Anyone else got any other solution or experience on this matter?

Try cycling the power 4 times with the throttle grip in the idle position. This allows the ECM to relearn the zero postion of the twist grip sensor. Then make sure your throttle grip is not sticky...which can cause issues if it doesn't return to the zero position every time. It can also learn the wrong position if you shut your bike off with the run stop switch...with your hand on the grip.

There should be no need for anything to "relearn", or any of that crap.

The engine will idle at up to 2,000 rpm or so briefly in cold temperatures, and the idle should reduce by itself gradually as the engine warms.

Once it reaches normal operating temperature, it should reduce idle speed to about 1,000 rpms, give or take. If it's not doing that, something's wrong.
