    My 07 norge shakes like a harley at idle. It also seems to be running a bit rough between idle and 3k rpm. I dont know if the inner spark plugs have ever been changed. (30k on engine) The only reason I'm complaining is that the vibration is so bad it's making my hands go numb while riding. Is there anything I can do to alleviate the vibration?

    Also noticed that when the bike is fully warmed up and I pull the clutch in to come to a stop the revs drop like the bike is about to stall then goes back to normal idle. I'm an acura mechanic and typically on cars when this happens it's a problem with the IAC circuit. Im just curious if a tps reset would do anything for me.

    Sounds like you need to balance the throttle bodies and then do a TPS reset. Also cleaning out the stepper may also help the RPM drop issue. Replacing parts is the last thing to do.

    You & I both have the "same" bike. Congratulations on your obvious wisdom, intelligence and long-suffering.

    In my ongoing quest to make mine all it can be, I offer you & others here this gathering of tech tips for the Magnificent 2-Valve, Norge (and Breva & Sport & Griso):

    These topics are covered over and over again here. Please spend some time to search and read... and also, nearly impossible to diagnose via words only here. We don’t know the history of the bike, and due to the age, nearly anything can be amiss including clogged fuel injectors. If that is the case, the injectors should be removed and professionally cleaned, and then what John states above. If you don’t have software for tuning, you are stuck.
