whistle through vents

[buzzcut]

Hi all

I have a whistle noise through my front vents at hwy speeds. Left one seems worse, i can close it and whistle goes away. tried different angles etc. I have checked through and through and I am unable to see anything that might cause it. Anybody else have this and were you able to determine the cause?

thanks

Mine does it too depending on wind angle against the fairing. I think whistling is going to happen to some degree if the wind speed is right so it's a trade off between ventilation and potential whistling.

That was another thought lol

I had a noise at certain speeds, I thought it was whistling through the vents, but it turned out to be #1 spark plug was loose.
