All the 750's and I believe 800's have carbs, The 1500 depending on the year were carb or FI. I think that the 900's are all FI bit I may be mistaken.
I have a FI Nomad 1500, advantage is when I did my earshave and exhaust I lust put on a fuel processor and can plug in my laptop and change it.
Don't have to pull out the carbs just download a new fuel map.
Also FI's you don't have as big of a problem of jets plugging as the fuel is under pressure and will blow out the gunk with a seafoam treatment.
FI is also a little bit more responsive to the throttle.
