Basically my theory is proven by the fact that you have to handicap a twin or V4 by weight or restrictors in order to get a fair race with the I 4s.
And you have to go no further than the Ape RSV4 to see what inherent advantages the V4 layout produces...

And again, in AMA, when Hayden won. He won with an advantage. The 1000 I4's had restrictor plates. And before that it ran against 750's.
A V4 has no real disadvantage over an I4 when it comes to revs. The valve area, and piston weight/size should be roughly the same.
Twins very rarely compete evenly. Only when Ducati came out with the Desmo valve arrangement (mechanically linked the entire time, as opposed to being closed with a spring) have they made comparable power to the equivalent I4. Even now, they use an 1198 instead of a 1000. And the Desmosidici ( based off of the gp bike, therefore gp specs are why it's a V4) is outrageously priced and make the same power if not slightly more than a Gixxer 1000, and costs seven times as much.
I love twins. I dislike I4's. But, facts are facts. Four cylinders can usually rev higher, therefore do more work, which gives them an advantage.
