Reasons for Motorcycle Starter Squeaking and Not Starting

[DeJayce]

The most likely reason for a motorcycle starter making abnormal noises and not starting is a depleted battery, or corrosion on the battery terminals causing excessive resistance. Check if the starter relay is faulty, if the starter motor's coil is burnt out, if the starter motor itself is malfunctioning, or if the starter overrunning clutch is stuck. Below are additional details: Inspection Items: The electric start of a motorcycle consumes a significant amount of power, while the headlight and horn consume very little. Therefore, functioning lights and horn do not necessarily mean the battery has enough power for the electric start. Issues with the spark plug may require replacement. Sometimes, fuel can flood the spark plug—check if the spark plug tip is oily or wet, as this can also prevent ignition. Carburetor: If the carburetor is faulty due to prolonged use, it needs to be cleaned. In winter, cold weather can make it difficult to start the engine. In warmer southern climates, unless the motorcycle itself has a fault, starting issues are less common. In northeastern regions during early spring or late autumn when morning temperatures drop below 0°C, the engine oil may thicken, causing difficulty in starting.
