Engine/Transmission Rattle

My Spyder has developed a rattling noise when I let off of the gas. I searched the forums and do not see anything similar. The mechanic at the dealer I use has no idea what could be causing it, and cannot discern where it originates. He put the machine up on a stand to allow the rear wheel to spin and simulate on the road travel. Roll on the throttle, everything is find. Let go and rattle, rattle, rattle. The cycle performs well. Good acceleration. Good shifting. Just this noise whenever I let off the gas.

Any ideas? I don't want him to tear everything apart without an idea of where to go with the exploratory surgery.

It's hard to tell where the rattle is coming from but a few have reported rear bearings rattling or vibrating as the power is removed. If you have a Hindle exhaust check the heat shield, the rivies are well known to come lose and start rattling.

Good luck finding the cause!
