I decided to install a taller aftermarket windscreen which I like and works well. But I have an unusual problem. At highway speeds I get a buzzing like resonance which appears to be coming from that windscreen. The top of the screen is about even with my chin and if I raise or lower my head the buzzing fades. I printed some vortex generators which I'm experimenting with to mount to the windscreen and I will try the original windscreen as well. Just curious if any one else has experienced this? If so what did you do to correct?
I went back to standard
