What are the benefits of carburetors over fuel injection methods in engines? I have started working on motorcycles and have noticed that even modern motorcycles are carb'ed rather than fuel inject. Is it because of the cost of adding a computer? Or is there something else to it? I know that some motorcycle companies tend to get away from modern technology to retain a brand image, but working on my carburetor on my motorcycle I notice how much I can change the fuel system just by changing the jets, shimming the needle, changing the air/fuel mixture etc. But for a fuel inject, wouldn't it just be connecting it to a computer, pushing some buttons and off you go? Are there any benefits to carbs vs. fuel inject? Carbs seem pretty easy to work with to be honest, but I do understand that there is a bigger chance of wasting fuel. Also for cars and not motorcycles, how is it working with the carburetor?
