Howling noise

[CaptonZap]

Howdy,

I have a 1980 Yamaha XS11 with one of your fairings on it, and at speeds over 50 MPH, and with certain quartering wind conditions, a howling noise is generated in the cavity around the headstock.
Is that normal, and if so, what can be done to mitigate the noise?
Thanks for any suggestions.

Welcome to the forum! For the most part, the howling is normal and is a lot less than the noise you would experience if the fairing wasn't there at all...

Does your windscreen have the pop-out vents? I suspect that it doesn't as they tend to decrease the area of low pressure which is behind the windscreen which can increase the howling and buffeting.
