how does a batteryless efi system work without a battery ?

Usually when cold, the first pull charges the fuel rail and the second pull actually injects the fuel. Once warmed up, the fuel rail stays pressurized enough that a single pull generates enough juice and injects enough fuel for the engine to fire.

I'm not sure how Polaris is going to do this with the Fusion, but I can't wait to see the thing in action.

yea same here thanks!!
