I find this carb / EFI debate funny. Since there are other reasons to end up stranded, than just fuelling.
Anything can happen.
Lets put two guys on adventure bikes. The other bike with a carb and other with an EFI. They both ride 10 000 miles in same terrain... Then lets gamble...
For the carb to break. 1 to 40 000 chance
For the EFI to fail. 1 to 38 500
To have a flat tire 1 to 500
To bend touratech crap. 1 to 1
To simply run out of fuel. 1 to 2000
To crash and break a leg. 1 to 14 000
For the drive chain to break and "weld" itself between front sprocket / engine case. 1 to 8 000
For the rider himself to weigh more than his steed, resulting in frame crack. 1 to 2
I have never had EFI fail on me, on my cars and bikes.
Maybe time for the carb people to start eating all that can food, they piled for the 2012 end of the world thing....
