Just bought a well taken care of 2008 Ulysses XT with 13,700 miles.

However I observed the following idle issue on a pre-buy test ride.
* Starts cold and goes into warm idle mode at 1400 in neutral with both the Clutch in and Clutch out
* Let it warm up and test drove for 5 min,

When I got back from test ride, in neutral again with clutch in it idles at 1100 as expected.
However, when I let the clutch out the idle raises to 1900.

After doing a TPS reset with both the bike cold and then again hot, it yielded the same results.

Called a regional dealer that hung with Buells to the end. A couple techs in the service department are still riding them (as well as couple guys in the sales end ) They didn't remember seeing this before and suggested to bring it in for diagnostics.

If the intake seal was bad, it shouldn't make a difference whether the clutch was in or out.

Before I take it in to the dealer, has anyone else run into a similar issue that they found a solution for this.

Did you back the screw out before doing the TPS reset?

Umm, I don't believe the '08s have a screw to back out. Idle is controlled by the ECU and an idle control unit.

If the change in idle speed depending on clutch in or out is repeatable, I would be looking at how the system grounds. IE, does the ECU ground one way if the clutch is in, and another way if the clutch is out.

Hope this helps, Dave

Further, your post caused me to browse the electronic service manual. While I didn't see anything in the diagrams that would lead me to a possible cause, there was a caution in the IAC section about idle issues.

One listed cause of idle issues was improperly adjusted throttle cables. Could there be an interference between the clutch and throttle cables? Esp behind the flyscreen?

Certainly a long shot, but easy to check.
