Madstad for F6B

[d-shark]

Do you mean inside the Fairing? As if air is traveling in the Fairing vents and as the air exits around the shield it whistles. hhuummmm
I do also notice a squeak at low speeds, and I can duplicate by wiggling the windshield... Something else to look at. Thanks

Early on I noticed the squeak you describe that can be duplicated by wiggling the windshield. In my case the rearward facing side of the Base Shield was contacting the Dash at a couple distinct points causing the Squeak when the Base Shield was flexed. Initially I applied Armour All to the contact surfaces allowing the two surfaces to slide against one another eliminating the Squeak.

Later I applied Frost King Rubber Foam Weatherseal 1-1/4" wide, 7/16" thick, purchased in a 10 foot roll at Lowes (#Black R516). Applied this in the gap between the Base Shield and Dash. This provided much more uniform contact surface between the Base Shield & Dash. This added contact surface also seems to stiffen the Base Shield resulting in much less flexing and no Squeaks.

I have what I would describe as a very faint Whistle at times (running with 11" shield). I can hear the Whistle only because the Madstad produces such low wind noise at the rider position. I can also hear sounds from the Engine & Tranny that I could not hear before as the result of the lower wind noise.

From the posts here it is clear the Whistle is Offensive to some and Barely Noticed by others. To me when I do notice the Whistle it's like a "Happy Little Birdie Whistling" to others it's the "Freaking Whistle That Won't Go Away". Those with an annoying Whistle might try applying the Frost King Weatherseal as I describe. It really provides the Base Shield with quite a bit more support & rigidity to eliminate flexing and might help to minimize the Whistle?

The squeak I will look into this eve. Thanks for the info on your fix... The whistle is real bad. Depending on the angle or height I can still hear it up to 70mph. And that is with a 13" shield. At 40mph it makes me crazy.
