The sender works on a resistance coil with an arm controlled by float. If the bike has been sat for any length of time with a near empty tank corrosion can build up on the wire coil which will affect the way the sensor sends the signal to the gauge.
Empty the tank and remove the sender from the bottom of the tank and you will see contact points on the end of the float arm if you can see corrosion clean it up with some scotchbrite (nothing to abrasive) and then flush with some brake cleaner.
This should help, if not and there is nothing wrong with the wiring then replace the sender
