Harley Port, flow and velocity Question

First off, all Harley Haters move on, I do not care what you ride or like, please do the same for me.
Now-
Is this idea worth postulating-?
The ports and length of the intake system on a Harley is absolutely short.
Combine that with the long stroke, things do not get going very well for port velocity.
It has to be a bumpy ride to the combustion chamber.
Lots of stops and go signs untill about 4500 RPM.
I would postulate the manifold should be longer .
I will also say that because of "looks" the carb or throttle body sticking 6 inches further out into the rider's leg, is why this is not addressed.
Your thoughts?
