Here are the simple solutions for a motorcycle fuel gauge not moving: 1. Remove the fuel level sensor from the fuel tank, turn on the ignition, and manually move the float up and down to see if the fuel gauge needle changes. 2. If there is no change, disconnect the float wiring, and directly connect the wires from the harness to the float (for two wires, connect them directly; for three wires, connect the other two wires to the ground wire separately, connecting two wires at a time), then observe if the fuel gauge needle changes. 3. If the fuel gauge still does not move, check if the wiring under the fuel gauge is loose. If the wiring is not loose, it is possible that the fuel gauge on the instrument panel is burnt out. In this case, you will need to take it to a repair shop for servicing.
If the motorcycle fuel gauge stops working, first check the most likely culprit—the fuel level sensor inside the tank, which is prone to loosening or dirt buildup. Disconnect the plug, clean the contacts with an alcohol swab, and reconnect tightly; this solves most connection issues. Another quick trick is to gently rock the bike—if the needle jumps back, the float is stuck and temporarily freed. I’d also check if the fuse is blown by locating the fuse box near the dashboard and replacing it (refer to the manual for its location). If these don’t work, develop a habit of tracking mileage: note the odometer or reset the TRIP meter after each refuel, and top up after about 100 km. As a temporary measure, use a stick to gauge fuel depth to avoid running dry mid-ride, which risks safety. During regular maintenance, clean the tank to prevent debris from clogging the sensor—these small steps save time and money.
