I am not sure how the Ultra is vented, but its probably vented to the air filter. Look at the back plate of the air filter and you will probably see a hose coming from the bottom end of the motor. that is the vent. What happens is a little oil goes with the air. You can remove the hose and vent to the bottom of the bike. That will stop the drip.
On the bogging, pull a spark plug and let me know what color it is

Answer
The hose I was talking about doesnt come out of the carb, but out of the backplate for the air filter which attaches to the carb.
Your heads are vented via a rubber flapper inside the rocker box covers. They might be bad and letting oil come through. Also you might be getting spit back from the exhaust. What this is is not enough back pressure on the exhaust system and some air is pushed back through the intake valve which pushes gas back through the carb. If you have oil from the heads going in there the oil and gas are being pushed back out.
Try opening the pumper on the carb a little to stop the bogging. If that doest work let me know
