I guess I don't share your negative experience. I have two bikes with carbs. They are not new bikes, sorry but not everyone can fork out the dough for a newer bike. I have had them since new and have never had any major problems with the carbs. They are paid for, and they work great. There is nothing a newer bike with FI can offer me that I don't have right now. I rode my ZX9R across the US, up mountain ranges and down into valleys, thru dry and humid climates, and the carbs worked great. Why would I need FI?
The problem with fuel injection is that if you tinker, FI is not exactly a do-it-yourselfer friendly accessory compared to carbs. True on cars as well. Modifications require expensive purchases. Try, for example, buying new injectors for something like a 300ZX twin turbo (or any Nissan Z car for that matter- I have owned three of them). The throttle response on FI also has been a major complaint of testers of new bikes from various manufacturers. Sometimes several model years go by before that is worked out. Go back and look at the first FI GIXXER, I think it was 1998, for example, or the VFR. Not so with carbs.
That does not mean I think FI is bad, evil, etc. It belongs on new bikes, but carbs are better if you are going to do mods on your motor and want to do the work yourself as far as tuning, unless you are loaded with money (maybe you are, but most do-it-yourselfers are not). Carbs also allow a manufacturer to market a less expensive bike.
I have rebuilt some large auto carburetors on cars I have owned, and have taken apart bike carbs. Bike carbs are tinker toys compared to a Quadrajet carburetor. But if you are not very mechanically inclined, then I can understand getting upset trying to work on them. FI is better for the mechanically challenged (let the dealer work on it for you).
