Trying to change the primary oil for the first time (for me) in my 05 Fatboy.
The correct plug is in the lower rear section of the primary between the lower case screws?
Allen head?
If this is it, it is holy sh*t tight! I dont want to round out the allen.
Any ideas?

Sounds like you've got the right plug, but I wonder if someone put Loc-Tite on it in the past? I don't have my owner's manual in front of me for reference(the torque is listed there) but I know it's measured in inch lbs. and not foot lbs.
If you're worried, take it to the dealer & pay them $5 to break the drain plug loose for you. You need to go there anyway to get a new gasket & o-ring...

Good luck.
