Well, I started this thread. Too early to tell, but picked up bike from wrench today. I had picked up new seals, dust caps, bushings, clips and what have you from the dealer. Showed the wrench the input from the fellow with the leaking FJ1200 (I had one, an '86 for many years and thousands of miles) forks that fixed by sealing the fork seals to the fork external.
I asked him to pay close attention to see if he could figure out why I've had three leaks in 18k miles. We ended up ordering a new right fork upper tube. Looks like there were flaws in the finish at a few different points, one or more which were about where the seal would be sitting while on the center stand. Others at various travel points. He tried to polish them out, but they were irregular "pitts" in the finish which would surely have been something that the seal would not be sealing as it traveled over and past, or parked on the center stand. Even after considerable "polishing" the "pitts'w were still more than evident. This time there was a good deal of oil that had puddled on the wheel's rim as it was on the center stand and in a left turn positon.
Too soon to tell, but, we think I shouldn't have anymore fork seal leaks for quite some time. Fingers, Toes, Eyes crossed!
