Hi stopped to fuel up my Ktm 640 adventure 2000

You might find the manual and wiring here.. http://www.manualedereparatie.info/en/categorii/ktm.html
please rate me if this helps.
Thanks

The engine is running too rich. The carburator needs tuning to get the fuel mixture correct or the choke may be stuck in a partially closed position.

It could have been bad gas.

It is not making 12 volts,check batery , needs to be replaced, needs to be replaced ,bad battery. Mopar Kenny.
