What do you consider a rough idle, is the engine ignition not firing on both cylinders? The 08 I have shakes like a nun in a whore house and it runs great, basically this is the nature of the beast and that the true HD signature IMO. If it sounds like it is running on one cylinder when the engine is HOT and you are stopped then it is the heat management system, the heat management system can be turned on or off depending on the riders preference.
