Issue: Roof rack is making wind noise when traveling at moderate rates of speed.
Cause: As the air flows through and around the rood rack, it creates a harmonic resonance that you hear as noise.
Solution: Disrupt the flow of air. This can be done by wrapping your crossbars with something like paracord. Wrapping each crossbar in a spiral fashion an approximate 2" to 3" gap between each wrap. Your fairing may still need to be modified to close the gap between the fairing and the roofline. Lastly, your recovery boards are likely making a lot of noise. Rotate the recovery boards 90 degrees. The recovery boards need to be facing lengthwise and NOT crosswise.
When making the mod, remove the recovery boards completely. Then add them back after wrapping the paracord around the roof rack crossbars.
YouTube has a lots of videos on the subject. Hopefully you will find a solution. Good Luck.
