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?
