It's not a drain plug, it's a passage plug.. I've yet to remove one...
I have been told that it is a drain plug and I even pulled mine once and out came 5oz of oil.. Which I was also told was ok..5oz ain't that much to be considered for sumping. See #2 in the following pic.. When you install the pipe fitting plug use for with PTFE and don't over tighten, it's a tapered plug..
Ahh yes,, The flat rate trick the comes back to haunt.
I'm interested to know more. I'm the mechanic and I didn't deliberately cut corners. I read that the stock oil pump was sufficient for mild stage II build, not true? I'm going to crack it open again, so I'm interested in all recommendations while I'm in there.

The stock pump is fine for any build.. The issue is leaving the pump on the cam plate during assembly leaves a chance for misalignment of the gerotors and damage to them or the wavy washer. Also if the pump is misaligned to start, the case O ring that connects the scavenge pump spigot to the can suck air, loose prime cause sumping..
I hope you used a new viton O ring at that location.. Part of the pump alignment procedure is to ensure that the pump spigot is centered on the O ring..

Yup, all new O-rings and gaskets and I'll do it again when I tear it open this weekend. So, at a minimum I should dissemble the stock oil pump and look for damage when I'm checking things out? Since I'm in there should I just swap it for a Feuling pump? Nothing super high-end, just the HP+? My Dyna isn't going anywhere and may end up with a 110 kit soon so it wouldn't go to waste.

Check outer cam timing for the heck if it..
I wouldn't go with the Fueling unless the stock pump is bad. I've been running a stock pump in a 10.5 to 1, 107 bagger for 36000 miles, and 55000 as a 103 and 15000 as a 96. 116000 total. No problems..
Well, a new Cometic gasket/O-ring kit is ordered. I'll get the bike back on the lift tonight and start tearing it down...I really hate taking Thunderheaders off and putting them back on. I'm not going to bother with the plug on the crank side of the case, if there's oil in there it'll show up missing from the pan and after things are put back together correctly it'll get picked up by the pump and mixed with the new batch.

@Max Headflow Not my intent to hijack the thread. Learning a lot from the discussion. I just did my first cam install on a 117 and I left the pump on the cam plate. It was a pain to get it aligned to go back on, but it finally slid into place. What symptoms would I notice if I misaligned the gerotors?

If you misalign the gerotors and jam it on, you can potentially crack the inner feed and loose oil pressure.. The other concern is poetically miss-aligning the cam plate on the scavenge port and leak air causing sumping. You can possibly do other damage to the pump. The guys that leave the pump on pretty much know what they are doing and make sure that parts line up.. Some inexperienced guy may not notice the hagup and forces things.. Bad things can then happen.. and have..
IIRC when Steve Cole and $tonecolds cam testing, they left the pump on the plate but they "had the feel".
I pretty much pull the pump separate and inspect just to make sure all is OK..
If you got it together and no issues with some miles, Don't worry.
