Just wonder in anyone has heard of this. I can hear a high pitch whine or whistle, not a brake dust squeak, coming from the left front of the bike when i get above 30 miles per hour. its annoying as hell and gets distracting. I've tried pulling in the clutch to see of its motor related and its not. it does not change with rpm.
I don't think its wind noise cuz it doesn't change with gusts. any more ideas?
My broinlaws '05 Road King Custom with a Dragon Fly fairing did that.I could hear it when he was riding near me.Never found out what was causing the noise,his bike was stolen.
