That happens to me almost everytime I ride my bike. I hear it's associated with the heat, most likely from the radiator. If you push the botton and feel the horn, you can feel it moving outwards as if it want's to honk, however it doesn't. I heard it's common on Suzuki's. I don't know what to do about it, though, my dealer out here said they almost all of them do it, and he'd replace it for me but he doubts that it will change anything. I am thinkin' about gettin' a cheap aftermarket 12v horn.
That's funny shit !Yeah that happened to me the other day. It was right after a wheelie that came down kinda hard. I tried using the horn and didn't work, so I thought I knocked something loose. Gusse it's happing to everyone eles. Oh-well I hardly ever use it anyway.
