Thanks that makes perfect sense. I didn't know that about the connecting rod. I would have assumed the front and rear rods were 180 degrees apart on the crank. So what you're saying is the front piston follows just after the rear piston and the rear sucks in all the air and there is not a lot left for the front? So increasing the intake volume allows more air to be left over to fight this problem?

Yes.
That one pin design gives Harleys their unique sound.
