Daz, thanks for the explanation re aligning. Nice job!
Dave, I live in Dartmouth. Might be taking you up on your offer, if after riding this weekend that squeaking returns. Thanks for the consideration.
When the noise was at its peak, and I was pretty fed up with it, at my next stop for gas I took the windshield cleaner brush and wetted out the rear pulley and part of the belt in an attempt to clean it. The squeaking did diminish for a bit, but only to return, Maybe the water acted as a lubricant?? Anyway, how about using a belt dressing? My dealer had previously mentioned trying furniture polish on the belt. I bought a can while passing through Sturgis, and threw it away the next day. Didn't help one bit.
