who's been having to add transmission fluid?

If you have that, take the cover that holds the slave and fill the area where the main-shaft fits with puddy. Then bolt it up to your gear-set. This will push the puddy out and leave you with a nice shaped piece of puddy when you unbolt it. This gives you the small gap area you have to work in. When I made my slinger ring that what I did to get it to fit in there.

The shop called today. Said the were going to do the crank seal gizmo. Then he went on to say they were going to change some seal at the tranny. He continued stating that they were going to change the rod that runs through the mainshaft and send all the parts back to Harley.
I"ll know more come Wednesday when I pick it up. I'll get all the part numbers and report back. There are a couple of things there doing that hasn't been mention on this tread. He called me at work and I didn't have a lot of time to ask questions.

Found some of my old photo's of when I puddied up the area. As you can see there isn't much room to work with. I cut the first slinger ring from AL. and glued it in place. Then made another out of high temp plastic with a sleeve on it to push into the mainshaft. This holds it in place and reduces the ID of the shaft at the same time. While it helped some, it does not stop migration at all, at least in my testing anyways.

Thanks, for the pic Steve. The clay reveals the issue.. It may simply be how casting ends up that some bike have the issue and some do not. The OD might be slightly smaller on some allowing for clearance and the oil to drain..
I assume that looking at the clay, the circle is the OD (yellow) of the bearing in the trap door and that the boss where the clay is machined to the same level as the gasket surface. Looking closely, you see a ring along the outside edge of the boss where the boss is bigger than the bearing. This area will only have about 1/16 inch clearance between the inner cover and trapdoor for oil to flow out due to the cover gasket so the cavity can fill with oil if enough is dumped through the mainshaft bearing. The cavity fills to the point where oil transfers.
IMO all that is needed it to machine the case area down to where the red arrow points and no oil will be caught in that region..
FWIW, IMO simply cutting slots for drain may not be enough..

Not a lot of real info here.

Looks like that inner ring/lip where the pushrod runs through (where the putty is) would be about perfect for collecting moving oil and directing it right onto the exposed pushrod end.
Remove that, and there is no cavity for oil to collect nor for oil to be directed. Just machine the face of that thing right off.
