rwilliamm, (I have read your posts but not each and every answer, so I apologize in advance if these ideas have already been discussed)
From your description, I think it is a dynamic problem on frame, steering or wheels (mounting, tires, etc.). I have an easy experiment for you: put some luggage on your left bag, something significant, like 15 pounds or whatever it fits (I think they are rated for 20 lb). See if that helps, or maybe it makes it worse, so you can try on the right bag.
Also, check your body position. Are your "cheeks" right in the middle? Before I had the C14 I drove an R1200RT and that one did pull, but it was down to the one side swingarm, so I got used to drive it seating with a slight lateral offset on the seat. When I got the Kawa (mine doesn't pull) I had to re-set. You don't drive with some luggage on the bags, do you?
Finally, try other C14s (easier said than done) to see if you notice the same: it could be just your feeling, but from your description I doubt it. And get somebody you trust to drive your bike.
