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.

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.
