I have a 2011 Ultra Limited and when I roll on the throttle it clicks. When I say "roll" I mean to pass traffic, or when I get on it hard. Normal acceleration and the click noise is not heard. I'm not knowledgeable w/ fuel injection bikes or this newer throttle by wire set-up. It reminds me of the sound when the throttle/idle cables on the carb'd bikes make when the cable assembly hits it's max position. Hope this has made sense.

 

With the engine off,does the throttle click when twisting it?

 

It does NOT click w/ engine off.

 

my fat bob clicks to in this scenario. i just noticed it the other day and was hoping to see a thread on it here before i take it in to the shop and ask about it.

 

See if your throttle grip is in enough in the bar,that happened to me until the throttle grip sensor slipped out leaving me with no throttle.Loosen screws on master cylinder and throttle assembly and remove throttle grip.Check and see if there is any wear on the end of the throttle grip sensor and grip(the teeth on sensor are plastic,if so grip is not in enough and it skipping causing it to click) and adjust by sliding master cylinder up a bit followed by throttle assembly and reinstall grip.Hope its that.
