George,
You are correct but remember the manifold efficiency is based on having the correct size runners to begin with. The venturi is needed to improve vacuum to draw fuel. The Weber has a secondary venturi as well, the little bullseye one in the middle. So things are complicated in any case. A well tuned FI is almost always better.

Bill,
I love the concept of FI, it's the electronics and the complexities of it all that worries me. I think Lynn said it best, FI is almost always better - provided you have power. I couldn't have said it better myself.

That statement struck a note for me, as I remember when I was traveling by myself in a very remote part of north Western Australia on a new bike (1800 Suzuki), it's got fuel injection the lot, all of a sudden it stopped and I was thinking %^&(*^$# how in the hell am I going to fix this out here. Luckily by the time it rolled to a stop I realized I had bumped the kill switch - -but for that moment there was a lot of anxiety.
