this weekend i attended the BCM Winter Bluez Seminar. absolutely awesome! people from all over the country attended. the topics covered were: 2 and 4 valve adjustment and suspension. there was lots of hands on, spilt rings and shims galore! we even got to see the new testa strata heads. even if you never intend on touching a tool to your Duc, the trip is worthwhile. the knowlege you gain will give you a deeper apreciation and understanding of your beloved machine. Bruce, Suzie, and crew are super, gracious hosts.
