Is there any oil on the cam cover, or around the lifter covers? IF that did come out of your ride it's in the wrong spot to be leaking from the transmission drain bolt.
Check your engine oil; cold. On the jiffy stand. If it's over 3.5 hash marks on the stick you're overfilled on the engine and it's puking out the A/C.
First, vent the crankcase gasses to atmosphere; second follow the spec on the oil fill; and third, do you own work

What do you mean by "vent to atmosphere"? I can just use a straw to draw the oil down (slowly)... is there anything else I need to do to fix this?

Typically the engine vents oil vapors back into the engine. "Vent to atmosphere" is adding after market hoses from the heads to a little breather filter or a small collector, thus venting oil vapors to the atmosphere.

Sounds like you're correct. The oil isn't leaking other than when I am riding... it splashes into the A/C and continues to leak after turned off. It's not making much of a mess anywhere else. Checked the oil and its near/past the top line cold... definitely way too much oil in it.

Yep, past the 'hot' full mark when she's cold, she is certainly overfilled. You can use something like a turkey baster to reach in to the pan and draw off the excess oil or you can just pull the oil drain bolt and drop the oil in the pan and refill to the correct level.
I always tell Dyna owners to fill both the transmission and the engine to the stick and to not think in terms of 'capacity'. If as you're doing fluid changes you trust the level on the stick you'll never overfill. With a engine/oil filter change add 4 or 5 ounces to the oil filter to pre-soak it, add enough oil so it reads at 3.5 hash marks on the stick and you'll be just about perfectly on the mark.
As seniorsuperglideE8 mentioned, venting to atmosphere is re-routing the hot, oily, oxygen depleted crankcase gasses so they don't vent back in to the A/C and in to your throttle body and intake; that does your engine no favors and only makes the EPA happy
Running the Big Sucker which is EPA compliant you'd need to do a DIY drill and tap of the standoffs but kits are available to make it an easy job. http://www.dkcustomproducts.net/all-...ngines-c76.htm
Once you've drilled and tapped the standoffs you'll have multiple options for routing of the vent hose. Kevin at DK Custom has multiple images of the Big Sucker with some very discrete external venting to give you some ideas of what you can do
