Kind of the "same boat" for me..I do have a "slight drone" with the Cobra pipes at certain speeds. Not so much with the open face HJC 3/4 helmet but much more noticeable with the Shoei 3/4 and face shield down...After riding the bike, going on its 4th season, I am reasonably convinced the "drone" is a combination of the Baggershield and helmets...If I ride with no helmet and stock shield the "drone" is gone but the wind noise is terrible.....After all this time, I have become used to the sounds and plan to leave things alone. BTW, I cannot stand to wear any kind of earplugs as they drive me nuts...Had this issue for years however and my hearing to still pretty good at 77 years old!!!!......Ride safe
