Oil level remaining at center of bubble in spite of so much "oil" pouring out the pipe were it bolts to header where the pipes meet the baffle ---

Perhaps it isn't "oil" pouring out. Because the oil level should drop when losing so much oil.

Perhaps #3 cylinder is failing to combust, for whatever reason, resulting in "wet" plug.

Perhaps engine is running on less that all four cylinders.

Perhaps all the unburned fuel from cylinder #3 is collecting inside the muffler, where it combines with normal exhaust carbon, to form a black liquid goo that drains out looking similar to oil.

Just thoughts.

Good Fortune!

You mentioned you just bought the bike. Maybe it had problems in the past that let oil into the exhaust and the previous owner fixed it prior to selling it to you.(That would explain why the motor is so clean) Maybe a good long ride would burn out the oil, as long as its not still leaking into the pipe.

Go to the carwash with a hand full of quarters and a can of gunk and clean off all the oil. Then spray some white foot powder in an aerosol can where your gaskets are and the leak will magically appear. You will have some white powder on your motor when done but will wash off with water.

You're running too rich.
