Maybe the oil is just cooked. Or my oil pump is not working properly?
I'll post what I find out in hopes of helping some other poor bastard down the road.
Wish me luck!
If the oil is cooked the level doesn't matter. The oil just runs out of the head while the bike sits. As soon as the engine spins up and the oil pump gets going it supplies oil to the head and all is relatively good. Does the noise go away after it idles for a bit?
