Is there something unusual about that video that I'm missing? 

Isn't that what Bricks do when you push the start button?

Nothing that I saw except that its happening in December when I generally don't get to hear that sound...Don't read too much into it. I didn't.

I've always wondered about what I'll describe for want of a better term the "whistling" sound up to about 2500 RPM. It settles into a nice soft purr above that.
The sounds of the K75 are to me, fascinating!

I think the whistle is the exhaust flowing over a baffle in the muffler. 

My K75 gets a nice snarl at 5500rpm and above when I give it throttle.

Mole-rats have 17 different vocalizations. You're in for a treat!

Haha that's what happens!

I thought the sound was fluids circulating somehow in the engine or maybe the oil pump. I don't know how to determine and anyway I like a bit of mystery in my life.
