Heres you quote: "I laugh at that statement every time I hear it. Mechanically the EFIs are a small engine like any other. Still has pistons, valves etc that every mechanic has seen before. Instead of a carburetor, they have a Bosch fuel injection system that consists of an injector, a few sensors, and a small control computer. EFI is unbelievably reliable compared to a carburetor. Surely you drive a car and I don't have to tell you this!! The computer even reports error codes if there is an EFI problem. Think about your fuel injected car and truck. Are most problems related to the fuel injection, or the age old mechanical parts .... old principals still apply when working on an EFI engine. In the USA thats talking down to someone, explaining how efi engines have pistons, valves, instead of a carburetor they have Bosch fuel injection, surely you drive a car, etc, etc. Sounds like you talking to a group of preschoolers instead of your peers. Well so we got off on the wrong foot my Canadian friend. I have worked around fuel injection in many different areas and have personally seen problems with injectors (I've taken boxes full to be rebuilt), pumps, fuel pressure, mixing too lean, mixing too rich, sensors failing, oxygen sensors not sending the proper voltage, leaks, ground problems, and the list goes on. Usually they are dependable but when they do fail it can be expensive. I've really never had alot of carb problems. I've had alot more efi problems with equipment, autos, truck, heavy trucks etc. And I think Bosch should have put in safe guard against such things as using a battery charger or jumping one which they probably have by now. Bad engineering. Have a good day my friend to the North.
