Over the course of my ownership of a yz250f I’ve struggled quite a bit with my carburetor. I’ve thought a lot about converting it to fuel injection but need to hear from others that know more than me about it. I know that efi requires power which means I would have to attach a stator or alternator to my bike right? Which from my knowledge would not be easy. But even with an alternator would I need a battery aswell? Just looking for more information on the topic there isn’t a lot online (probably for a good reason).

Yep, there is no easy way to do it.
You'll need a battery/charging system, injector, fuel pump, o2 sensor, throttle body position sensor, power commander, crank position sensor, fuel rail, and tons of connectors/fasteners.
At best, you'll have an 80's style throttle body injection and have to create a custom map yourself for the power commander.
If you're an engineer, this would be a fun project and not beyond possible, but will it be as good as a carbureted model? Doubtful.
Look into a EFI bike if you're interested. -BIG DAN

As Dan said, by the time you put together all of the components and engineer it to work, you will have spent more money than if you just bought a bike already setup with FI from the factory. If you set a carb up correctly, run a good non-ethanol fuel, and don't have any major elevation changes where you ride, you shouldn't have any issues with a carbureted bike.
