Don't know if you got this fixed yet, but did sounds like the same problem that I was having. My mechanic at Cochise Motor Sports, Sierra Vista AZ found the problem. It was one of the Covers (Upper or lower) off the front fork that was the making the noise.
Hey LeLand, 1st off, EXCELLENT JOB on the accessories. I noticed on your great picture that you had a vent on your wind shield. What part is that, where did you get it from, and lastly, is that still the stock windshield?
Thanks
Joe
