NEWS UPDATE! I have found the problem. It is not likely related in any way to the BB.
The older models have a rotary breather with a hose coming out of the crankcase behind the left cylinder that goes to a fitting behind the right carb. I pulled the hose at that fitting and it was very oily. My service dealer says there has been some trouble with these and the newer engines don't use the rotary breather. The breather and seal may have to be replaced.
I then checked the two plugged drainage hoses that are under the bike. The one from the right side was full of clean oil. The dealer is now holding the parts which they have in stock (breather, gasket, and seal) Just parts and 1 hr. labor to repair along with my 4 year service. Whole lot better than a major engine problem.
The breather/seal problem definitely would explain oil consumption and why my right plug is usually oily at the base even though the bike is running great. This is something you other guys with 05 and earlier bikes should be aware of. If it seems you're having to add oil, check the breather hose and drainage hoses. It may indicate a failed breather or seal.
