the mount where the horn is located you will see that it is mounted to the engine. but it didn't fix all the problem. come find out it fix the noise when i am riding, but it still make noise when i am stoped. i hit the throttle hard as it comes down i hit it again and it will chirp, squeal, squeak or what ever you call this noise. i will look tomarrow when i have some light, there has to be something else that is loose that is making the noise.
