The newer Roadie hummed pretty good on some of the curves on our recent road trip through the Smoky's. I'd be more concerned about those high speed speed bumps on south US 35 by the VA Center in Dayton. Holy crap!

. Thanks for the replies..
Okay, I understand the tire cupping on the Dunlops... On my '05 RK the original Dunlop front tire had 22k on it and you could feel and even see the cupping on it...
Never had the howl before...
Don't know if I agree that improper air pressure is the cause of my problem, as I said I check my tire & rear shock pressures weekly...

My original 407/408s started humming at about 6k miles. Replaced at 9.5k with Michelin CII's, which stated started humming at 14k. Picked up a nail in the rear tire at 16.5k on the Michelin CII's at 16.5k, replaced both at 16.5k, silence again with American Elites, will report when they start humming....

I have used a belt sander to remove the high spots from the cupping and it really makes a big improvement. The noise almost disappears and it's smoother too.
Basically you hold the belt sander about 45 deg across the bad section of tread (bike in the air) and let the sander spin the tire and grind off the high spots. You get a feel for it pretty quickly. The center part of the tread doesn't have any cupping so you skip that part. I didn't have any balance problems afterward.
