Whats the advantage over a bike thats Fuel Injected.

no jetting required, the ECU does it all

custom spark/efi tunes, things will get wild fast

ohh and less restrictive, carbs are a choke point to mix fuel/air, with injection all you need is the throttle body

anyone knwo if they are using map sensors or some type of element to read airflow?

Does anyone know if they have oxygen sensors on these bikes? That is pretty much the only way that it would know how to richen/lean out the fuel mixture in my mind. Unless it is like a for example chevy 350 marine motor, which is fuel injected but only uses preset values and doesn't change while operating. Anyways EFI sounds like the way to go!

EFI sounds excellent!

It's already in tons of ATVs, bikes are behind! We have a Polaris Sportsman 500EFI and you just start it and forget about it, regardless of temperature/altitude etc. The fuel mixture is just always right, it's the only way to go.
