Was wandering if anyone was having a noise under rocker box? It is constant at 2000 Rpm, and very loud on decel. Sounds like a Rattle Snake, Bike is an 09 Street Glide 2400 miles, dealer said to moniter closely and bring back if it gets worse. He tried to say it is nothing, although my wife can hear it from her VRod. Its not a small noise. Thanks for any help.

 

Long shot but check your clutch lever, also your shift lever. A lot of these noises come from a loose component that sets up a rapid harmonic vibration.
