Yes It will work nice on the black cases too. I use it on my bike once or twice a year to clean the engine up

As for cleaning unfinished surfaces (have not tried this on a Harley yet).
But I have used WD-40 on all the transfer cases I have re-geared.
Stumbled on it when installing my first set of 416 gears.
Makes them look brand new.

My old sporty had a painted motor, I used purple power on it and had no problems.
However.... nice bike as said above one of the better bike movies. And to me the bike was the star of the movie!
