baja designs generator/stator rewound?

If fitting the baja designs full lighting kit
Thats headlight/rear light/indicators
does the generator need to be rewound to power it?
or can i power it off my standard stator?
and do all xr650r's come standard with a lighting coil?

As for lighting circuit all bikes have power for lights and ignition just some have more power than others.
