The cross plane crank has a benefit also. It's inherently better balanced, so there is less vibration.

Older engines used flat plane cranks because they are a very simple design. It wasn't that there was any difficulty with these, it's just that the engines gave a lot of vibration. The cross plane crank was a newer design, created to improve the engines balance.

Make sense?
Yea, that is where I am kind of at knowledge wise...ahem.
Changing the crank throws, of course, changes the firing order.
Does this divide it better?
(Better impulses?)
