What Causes the Motorcycle Fuel Gauge to Not Display?

[StNova]

In most cases, the issue is caused by the fuel level sensor inside the fuel tank getting stuck. After being soaked in gasoline for a period of time, some sensors may expand, clamping the float and preventing it from moving up and down. As a result, the correct fuel level cannot be displayed. In such cases, simply removing the float and loosening it slightly should resolve the problem. If the fuel level sensor is damaged, it usually needs to be replaced as it cannot be repaired. In some instances, the issue may be due to loose wiring screws on the fuel gauge in the dashboard or a broken connection between the fuel float and the gauge. Tightening the screws or reconnecting the wiring can fix this. The fuel gauge itself is generally not prone to damage, but if it fails, the entire instrument cluster usually needs to be replaced.
