Here's my project in progress. > http://www.advrider.com/forums/showthread.php?t=684054
Unlike you, I had no hesitation in taking the RT fairing off. Originally I was just going to go with a bear naked bike but when I found out one could still order an "S" fairing directly from BMW I knew exactly where I was going with this project.
BTW, the RT fairing is the heaviest fairing I've ever encountered. While I have yet to ride the bike sans RT fairing it's got to be a better handeler.
Good luck on your decision, which ever way you choose to go the old airheads are a fun bike to own and ride.
