Yeah, I got it, too. I was going to post the same question a few times, but since no one else was talking about it, I figured nobody but me was having trouble with it. Mine does it worst at an idle. I have found that by lightly pressing on inner fairing around the speedo or tach it will stop it. Have also found the pushing in or out on the windshield stops it too, so I thought maybe the windshield was the culprit. Went so far as to put an additional strip of the rubber tape they use on the outer fairing where the windshield mounts on the inner fairing side of the windshield itself to see if that would stop it. The windshield is in there a lot tighter than it was before, but I still have the squeak. Very annoying.
When I was inside the fairing last winter installing the H-D high output horn I looked around to see if I could find anything rubbing or loose, but everything seemed to check out fine. When I get some time, I'll have to tear into it again and take a closer look. [smiley=nixweiss.gif]
