Kawabuser: You are correct about that oil change procedure. My uncle's brother's son's girlfriend's half-sister's husband's daughter works at Kaw head office, and confirms that not only must you destroy the engine to change the oil on the ZX12, but also that, due to internecine squabbling among North American Kawasaki dealers, new ZX12 owners will be required to persuade Harley-Davidson dealers to perform any necessary warranty work.
With this kind of poor preproduction planning, I just know in my gut we're better off sticking with our Hayabusas.
