Sorry, but I don't like the "blacked out" look on any vehicle and especially on a motorcycle; they might as well just put a big piece of black tar paper over everything but the tank. Black on an engine is traditionally a sign of gross neglect resulting from a complete lack of any pride in ownership. Let oil, grease, grime, brake dust and neglect color it black naturally if you want a black engine and transmission. Maybe the guys who like black want their bike to only look dirty and neglected?
