This is not a recommendation, but a suggestion based on personal experience. Okay, where the bars clamp the the forks, there's a small screw in the front, you can't see it when sitting on the bike. This screw indexes each bar so, #1 they are in the same location, #2 it keeps the bars from rotating if, for some strange reason, the "pinch" bolts were to loosen, and #3 so BMW does not get sued in case the pinch bolts do come loose. It's a lawyer thing like everything in America is, but that's another story.
After removing these locating screws, I slightly loosened the "pinch" bolt, sat on the bike, and rotated each bar to where it suited my hands. I then tightened the "pinch" bolts to the proper torque spec and saved the locating pins for another time. I have ridden hard for several thousand miles with no problem, and not highway riding, but balls to the walls. Look at the crotch-rockets, they have this same adjustment.
Is there a danger if the "pinch" bolts come loose?....yes. Will the "pinch bolts come loose?....maybe, but not probable if the proper torque is applied and maintained. Will Obama win the Presidency, doubtful. I'm not saying to do this, but I have had no problems. It's a big trust
game and I trust my mechanical skills and the bikes engineering. The numbness for me has diminished so I'm happy.
