NO NO NO!
Six sigma is a program where there will be 99.99999% good parts. Windows is more like -99% good parts! I can understand your reluctance though if I was talking windows!

Bill,
Six sigma? isn't that like Windows, put out something flawed and get
everyone using it to act as problem solvers.

You are correct of course. The thing is that electrical power is more
reliably made than internal combustion! Don't forget that the operation of
a magneto realy is a simple generator. Modern alternators are very
reliable, and in conjunction with a battery as good as you will ever get.
A small secondary motorcycle battery will keep you running long enough to
get safely on the ground. The original Powersport system uses a mechanical
FI also. The Siemens direct injection is designed to be a six sigma part.
Once I can get that running I won't be worried. I am visiting my kids in
Utah. Driving here we drove across Nevada which is VERY desolate. There
are places where there is nothing for 100 miles. I wouldn't want an engine
failure there either but modern EFI is so reliable we take off and expect
to drive 400 miles at 75 MPH without stopping! The truck is diesel but has
EFI.

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.
