Here is the vented derby cover that I was talking about.....took me about 30 minutes to drill and tap the cover to accept the 1/8 NPT brass elbow and the compression fitting took care of the 1/4” inch copper tube.....I was just going to do it as an experiment but I kind of like the way it looks so I will leave it...
beauty truly is in the eyes of the beholder I guess

Well, at least it'll take a while for the oil to migrate up about 6" before it marks its territory on your garage floor.
And I suppose it's less permanent and cheaper than putting a hole in the primary cover or inner primary. If HD ever gets off their asses and permanently fixes the problem you'll only have to buy a derby cover.

The Harley vent is from the top of the transmission, not the primary. Not sure if there is likely to be more oil pushed out of a primary vent at that height and location vs the location that HD researched for their fix. A hard leaning turn to the left could result in a bunch of oil getting blown out that vent tube at speed.
