Crankcase threaded holes
I have a 2013 Ultra. I was cleaning the bike up today (oil airfilter blowby had run down the right side) and noticed two threaded holes in a milled out flanged area on the bottom right side of the crankcase, directly above the frame. I can't seem to find anything on this forum that addresses this, or what normally goes there, or what it's for. A shop manual is on the to do list, but any insight would be appreciated.
Someone in a post had made a reference to freeze plugs being in this general area, but without a manual I cannot confirm that. I basically just want to make sure that something vital hasn't rattled off, which I would be hard pressed to believe that two bolts wiggled free...and as a daily rider i haven't noticed anything different.
thanks!

If I am looking at that correctly, that is a drain hole for the cam case separate from the crank area(except thru the main bearing) for checking to see return side of the oil pump is OK if a sumping condition is indicated. It is a NPT tapered plug. It is very easy if you over tighten to break case, so it's best left alone. If not use sealer, and after it bottoms, a little more. The reason the cam case is separate from the crank area is for proper venting on a twin cam.

I have no idea what would go there but my 09 has the same stuff in the same place.
Nothing is attached to it. So.... normal I guess.
Might be something that is used in another platform like a dyna or something. No biggie.

look at the H-D engine stand, maybe these are the tapped holes to mount the cases to the stand......

Those holes (3 actually) are for an exhaust bracket on the Dyna models.. Dyna models mount the whole exhaust system to the motor / tranny...

Now OP; Why are you retaining the umbrella drains into the A/C and gunking up the throttle body and adding carbon to your valves & piston tops?
