Prob just your brain rattling around in that noggin.
Bout time something of his came out of the closet.Maybe one of them skeletons you keep in the closet got out.
Maybe.. it's hard to find it by yourself.. lolMight sound dumb, but maybe rocks or other debris in air intake tube and/or air filter enclosure?
I've already checked that... mine was tight dad's was loose! Doesn't really show up in the vids..There is really only one way we can help and that is for you to upload a video so that we can hear it! Was thinking possible exhaust leak! Remember PJ had loose clamps between the air filter and intake, it would be worth taking a look.
Header heat shields? Mine make loud noises when cooling off?I've already checked that... mine was tight dad's was loose! Doesn't really show up in the vids..

Lose nut behind the wheel?is it your axle?
Lol! Good shot!Maybe something fell up in when it was upside down.,
Too late now..You said like a card in bicycle spokes-- Does the "whirr" get faster as the RPM get faster? I think that would indicate something moving or rotating. It will probably end up being something very simple. But If you're in warranty, I'd sure take it into the dealer and have them listen to it before any bill in on you. I think even if they don't fix the problem, that you have a good case to have them pay in case it is something serious later.
