Been adding some farkles to my new-to-me 2010 RT. On a ride yesterday, I noticed that the engine won't return to it's normal idle (~1100 rpm) when letting off the throttle while riding. Engine speed drops to about 2000-2500, and will go down to normal idle if I force the throttle grip hard forward. The twist grip itself seems normal. I had the battery disconnected for awhile--could that be my problem?

Hi,
Sounds like you MIT have disturbed one of the throttle cables coming out of the Bowden box. It's on the left hand side under the plastic roughly where your knee goes when sat on the bike. Just check all cables are seated properly as they are easy to disturb when running wires.

I had the same thing happen to me when I hooked up my GPS.
One of the throttle cables was not seated correctly so the cable so
the revs climbed on start up.

As Mike says check the cables at the Bowden box.

Got it figgered out. After farkling the bike, when I replaced the gas tank the throttle cable got routed incorrectly, causing an unnecessary bend in the cable and additional friction. The planets are in proper alignment and the world is spinning in the right direction. Thanks for the suggestions!!
