if you take the time to uprade your heads, cams, exhaust, etc. you really should do the throttle body because it becomes the choke point of the build, stock harley throttle bodies arent known for performance, i took a look into it when the motor was apart and i could see it needed some work but opted not to do it at that time "MISTAKE" a good port job and a 3mm larger throttle plate will yeild almost 30 more cfm ,and a good set of head will really like that
