Recently my 16 Triglide developed a rattle or knock around the transmission side of the trike. I happened to notice it when leaving it running while dismounting to open the garage door. Decided to pay my dealer a visit. After riding it approximately 92 miles to the dealer I first verified that it was making the noise. Left it running and the service advisor immediately came out and verified the noise. He asked me to pull the clutch lever in, and the noise disappeared. Neutral rattle or knock, he advised me. I asked what was needed to repair. "It's normal, no repair". He then showed me a TSB from Mother verifying this. No explanation about why it showed up at approximately 9600 miles. The TSB was very technical, over my head. So, I'll just keep on keeping on!
