Most Common Reasons: Bike Ignition Switch Not Working
Dirty or corroded ignition switch
The ignition switch is a small electrical switch that is used to turn the bike on and off. If the switch is dirty or corroded, it may not be able to make good contact and the bike will not start. To clean the switch, use a small brush to remove any dirt or corrosion. If the switch is still not working, you may need to replace it.
Faulty ignition coil
The ignition coil is a small transformer that provides the high voltage needed to spark the spark plug. If the ignition coil is faulty, it will not be able to provide the necessary voltage and the bike will not start. To test the ignition coil, you can use a multimeter to check for continuity. If the ignition coil is not working, you will need to replace it.
Bad spark plug
The spark plug is a small metal device that is used to ignite the fuel in the engine. If the spark plug is bad, it will not be able to create a spark and the bike will not start. To test the spark plug, you can remove it from the engine and look at the electrodes. If the electrodes are damaged or fouled, you will need to replace the spark plug.
Incorrect spark plug gap
The spark plug gap is the distance between the two electrodes of the spark plug. If the spark plug gap is incorrect, it will not be able to create a spark and the bike will not start. To check the spark plug gap, you can use a spark plug gap tool. If the spark plug gap is incorrect, you will need to adjust it.
Improper fuel mixture
The fuel mixture is the ratio of gasoline to air that is used in the engine. If the fuel mixture is incorrect, it will not be able to burn properly and the bike will not start. To check the fuel mixture, you can use a fuel mixture screw. If the fuel mixture is incorrect, you will need to adjust it.
Low compression
Compression is the pressure that is created in the engine when the piston is at top dead center. If the compression is low, it will be difficult for the engine to start. To check the compression, you can use a compression tester. If the compression is low, you will need to repair the engine.
