UPDATE: I have some NEW info.

I couldn't find N while under power, so pulling in the clutch is the closest I could get.
I find the whine is loudest, or easiest to hear at ~4-5 RPM, but the exhaust drowns it out much higher.

-If I pull in the clutch @ ~4-5 RPM, but keep the throttle at the same cruising position, the noise does NOT go away! So I was wrong before.... likely because I would let off the throttle before.

-So now it seems the whine matches the speed of the ENGINE, not the BIKE.

The most logical cause I can think of is that the Cam Chain might be too tight... although I don't know how that would happen all of a sudden. Because the engine was so new, I did not put my manual tensioner in, it has the OEM unit at the moment. It seemed fine yesterday, and the CCTs usually LOOSE tension, not increase.

I don't know if this would work, but I was thinking about taking the cap off the CCT, and using a screwdriver to reset the CCT. I sure hope it isn't anything scarier than that.
