Help: Who knows this bad Noise?

Jim1963 said:

Sometimes my Rocket makes a bad noise.
I don`t know what it is. Two Triumph-Mechanics drove with my motorbike but they don`t know it, too.

Perhaps anybody can help me.

On the left side down of the homepage there is a mp3-Player.
There you can hear it.

Thank you.
