Not right from the start. I know my friend's '04 warrior was straight carbs and his '08 Nytro was efi - I don't remember about his '06 attak. I couldn't tell you what changed when. More than likely the newer it is the more likely to have efi.
I can't imagine a sled that has power steering without having efi!
Around the 06-08 years with all the 4 stroke launch came the efi, google the model is the best way i guess.
