The sender inside the tank has gone " open circuit " ( loose wire ) here is a video of Martin repairing a cb1100 cluster.
At 7.00 minutes into the video he demonstrates the indicator effect, then connects a 100 ohm resistor across the sender wires and it shows the fuel level half full.
The smaller the resistance the fuller the tank indicates;

The tank needs to be removed, emptied and the sender checked with an ohm meter, it's very simple if you know how to work a multi meter.
There is a remote chance one terminal is loose under the tank, easy to check with the tank lifted up slightly and watching the fuel display, could be worth a shot.
