Ejk - Electronic Jet Kit (Alternative To Power Commander)

[fruitcake]

Does anyone know, if there's a motorcycle which has electronic fuel injection, but no battery ?

 

I'm really curious

 

From the insructions...

"
<b>If your vehicle has a battery then attach the controller BLACK wire to the negative terminal of the battery. The ring terminal can easily be cut to allow fitment around a larger terminal post or bolt.</b>


For vehicles without a battery then an alternative grounding location must be determined. The grounding location must be metal. Any location with a bolt into the metal frame is a good location."

 

It does seem a strange thing to put - never noticed that.

 

I wonder if it's possible to go without a battery in racing/track days to save weight?  Can't think why on a modern FI bike otherwise.
