I finally got rid of this characteristic buzz from fairing around 3000 rpm. To fix the problem, remove headlight connector and rubber cover (49015). Than grab reflector and try to move it up and down. You'll feel some free play. If you won't feel free play, you have different source of buzz. There is a screw on upper left side of headlight. I turned this screw counterclockwise until free play completely disappeared. It took 1.5 turn for me. I have no idea what is this screw for, but it seems nothing got broken and I didn't need adjust headlight. It's already 200 miles with no buzz.
