It dawns on me that I haven't posted anything here about the massive Oil Burner Engine Swap Project of 2019.
After a lot of soul searching and upon strong recommendations from experts, I decided to swap engines instead of trying to fix/rebuild my engine.
My best guess is that the increasing oil consumption and fouling of plugs is due to valve stem seals failing and this may all be due to running the engine with a failed open thermostat for way too long. The problem was obscured by a temperature gauge that wasn't reading properly.
The donor bike has only 38,000 miles on it. The question was asked as to why I don't just run that bike instead?
Blasphemy!! If I were to do that then it wouldn't be my bike.
So where we sit now is that both my bike and the donor bike are disassembled off the frame. The frames are hanging like carcasses in my garage. My engine and the donor engine are on the workbench and I'm starting to slowly clean and re-assemble things.
