Hi Guys Ever since I bought the Ultra in '07 I have heard a faint ticking noise on the headset when the sound is over the speakers but the headset cable still connected. I use this configuration as I have a telephone interface and make frequent calls through it. The bike has been back to the dealership several times and on the last visit the headset, wiring harness and radio have been replaced aswell as filters being installed. It must be engine noise as it speeds up with it. Dealer doesn't know, Harley Uk and US have no idea and I'm sick of it. Does any other '07 Ultra owner have this problem? Or does anyone have an idea?
