"VB" is a family of Keihin carburetors. I'm not referring to an actor, movie or musical group. Older folks know that the phrase, "victor bravo" originated as the official NATO phonetic alphabet. You know, so radio communications wouldn't be garbled? Most of us were introduced to it on cop TV shows or in the military. Remember, "Mary, Ida, Ocean", license plate readings from the Adam 12 TV shows?
