Motorcycle Repair: drain plug, twin cam motor, clutch cable

Question
Where is the transmission drain plug on a harley twin cam motor

Answer
Looking at the right side of the motorcycle, it is underneath the transmission, even with the center of the right side tranny cover (where the clutch cable goes in).  It is just inside the frame tube on the bottom pan.  It is a 5/8 hex with a 1/4" allen hole in the center of it.
