This is a very interesting thread. Both systems have their advantages, however, it depends what side of the tracks you grew up on to see the facts in their entirety.
My younger riding friends are sold on FI. That is fine. They think carbs are ancient and complicated. In the modern day of plug-n-play, they are right. However, since they lack the common sense approach to all things electro and mechanical, they have no urge to learn about carbs. They have no issue with a $400.00 Power Commander, nor the $500.00 to $1000.00 laptop to make it go. Still can’t get it right. Through in a $150.00 dyno run to get it all right. Wow, that’s progress?
In the stone age (known unofficially as Before Injection, or BI), I could tune a set of carbs for under a dollar (if it needed jets, it was a few dollars more). All it took was getting my hands dirty and the desire to learn. Shims were about 5 cents at the hardware store and jets were a couple of bucks from the dealer. Once set up, they ran perfect every time. While a set of FCR’s are not cheap, they are still a worth while investment on your bike. And the best part is they will stay perfect when you are done setting them up.
I have not run into an FI bike that ran as smooth in all conditions as a properly jetted set of carbs. The only advantage I see to FI is emissions, which is why manufacturers went this direction in the first place (it was not in search of more power or simplicity). I currently have a 2002 750SS and if I attempt to tune it I have to spend a lot of money. I do not call this progress.
It all depends on your perspective.
