No.
Agreed; a nefarious factory "solution" for complaints of "flat spots" and such. If you want your V11 to have a tractable power band, practice the complete tune-up, ride, repeat. Lovely!
I agree. Besides, it just seems to make for more unnecessary complexity/issues to address a problem that may or may not exist on this big, fat V-Twin...
I like the idea of using the existing crossover to patch, and then maybe ceramic coat...
