I have a 2007 suzuki eiger 400 4x4 automatic and was wondering if its possible to go from a carb to fuel injection?

 

Somehow you'd need a crank sensor that works off the flywheel,an ecu module,tps,t bap,air temp sensors,complete harness,an intake that would accept a throttle body,fuel injector,plus anything else I've forgotten..Either live with this carb machine or sell/trade it for an efi machine if that's what you want.

 

We've got the answer to your question on the ATVC homepage and it can be accessed directly here:

I have to ask, why do you think you need efi? Do you ride in differing elevations or is your machine hard to start? Personally, I think carbs are a good match to these little off road engines, and there are a few tricks that can make them more user friendly if you have an extreme situation.
