Same experience as Stratofaster.
I noticed the same bolt was "weeping" a little after a hard ride. I wiped it off a couple of times - barely noticeble except for a little misting on the chrome right beside it. The dealer who is less than 10 miles away said it was a hard metal gasket that sometimes didn't seat properly.
He pulled both the one that was weeping and the one on the other side which was not and "smoothed and re-seated" them. He told me to watch it, and if it happened again he'd replace them with gaskets made of a softer metal.
The whole thing took about 15 minutes while I waited.
