unless the EFI makes it green sticker, I don't think it is such a hot idea. The FCR carb works so well and it is so reliable.
It sounds cool, but I don't see the real need or benefit.

Agreed, which is the reason why I am going to replace my XR 400 with a 2009 CRF 450X instead of waiting a few more years. I want the simplicity of a carburator and do not want to take the chance that EFI will be on the 2010 bikes.....at least that is what I am telling my wife.

I don't really understand why anyone would be worried about replacing carburators with fuel injection. The last time I had a car or a truck with a carb was in the 80s. I've put several rebuild kits in carburators, but I've never done anything with fuel injection. EFI systems have a pretty good record even with ATVs.
I'm looking forward to riding at any elevation without a rich or lean running motor. Modifications to the air box or silencer won't require jetting anymore.
I don't know much about utility quads, but aren't most of the new ones fuel injected?

Add EFI and now you have an injector, a more complex computer/module, a MAP sensor, Throttle position sensor, a fuel pump and maybe even an O2 sensor that can fail. With a carb I only have to worry about the spark box as the only item that I cannot fix on the trail. Sure the air fuel ratio may be better tuned for altitude but you will still suffer from low power at altitude unless they add a turbo. With the remote places that I ride simplicity=peace of mind.

Reliability isn’t an issue with carburetors or fuel injection. People will have their preferences but in a couple years you won’t be able to buy a carbureted bike.
Personally, I love the way dirt bikes have evolved in the last 30 years. I think the modern 450 4-stroke motors are phenomenal. They have awesome power at any RPM. Of course I don’t mind all the improvements with overall weight, suspension travel and handling. EFI is just a small change in the big picture.
