Went in to pick up the bike today. I explained my position, in a calm and reasonable way. The Service Manager is a M-F guy, so the writer took it to the GM, and I left with no money out of pocket. Will (the Service Writer), told me that the tech noticed that threads from the primary pulled off of the plug when he cleaned it, about a turn and a half. Sounds like someone cross-threaded it in the past, weakening the first couple of threads. He could have just threaded the plug in, but they didn't think it was safe. In any case, I now have a chrome inner primary - which I am fine with.
cahdbiker - Yes, I can bring in or specify other oil and they will use those. The previous SM (who passed away suddenly last December - real tragedy) used Red Line in the primary, and maybe the transmission. They also change all 3 boxes every service, even though the manual does not call for that.
