Well, I`ll never understand how less oil to the upper half of the stator (hot or very hot) will make the situation worse, since the bottom half, the half that is evident is in good condition because it is receiving more of this hot oil, is in visibly better condition. If the 'extra hot' oil is making things worse, why not just plug up the orifice completely? The size of the stock orifice is practically closed up now.
Many Jap brands use the same oiling we have here. I could`nt find info on flows, but these seasoned companies use exactly what we have and I`m sure our design mimicked theirs. I did find some falures of some Jap bikes, but the percentage of, has to be greatly less than ours. Be interesting to find the flows of theirs to the stator.

Dan, you brought up something interesting. We had are bushings redone. But add the fact, that has to be a huge oil savings in relevance to the size of the pin prick we have reserved for the stator. The original engineering flows did not account for this. I forget exactly how many redone bushings there were, but multiply that by the volume that is saved by making the circumference of the bushing smaller. I`m not going to attempt the math here, but in terms of 'pin pricks', has to be saving many.

As I asked in my original post, do you know why the oiling changed from the early S/N`s to the later?

Thanks for the input. .................... Serge

Just pulled the primary cover after 20,000 miles (always ran synthetic and had the tune... oil cooler since about 2500 miles).  Stator looked good.  Lower half of stator completely clean, upper half a bit of coking, but nothing substantial.  The orifice restrictor is in the stator bolt.  Just fyi...
