A motorcycle kick starter can make noise due to several reasons. Here are some common causes:
Gears: The kick starter mechanism consists of gears that engage with each other to transfer the rotational force from your kick to the engine. Over time, these gears can wear down or develop minor misalignments, causing them to produce noise during operation.
Engagement issues: If the gears in the kick starter mechanism are not engaging properly, they can produce clicking or grinding noises when you try to kick-start the motorcycle. This can occur due to worn-out or damaged engagement teeth on the gears, or if the kick starter shaft is not engaging smoothly.
Lack of lubrication: Insufficient lubrication can cause increased friction between the gears and other moving parts of the kick starter mechanism, leading to noise during operation. Regular lubrication is essential to ensure smooth and quiet operation of the kick starter.
Loose or worn components: Loose or worn-out components within the kick starter assembly, such as the kick lever, kick start shaft, or associated bearings, can cause rattling or clunking noises when the kick starter is used.
Damaged or worn kick starter gears: If the gears within the kick starter mechanism are damaged or excessively worn, they can produce noise during operation. This can occur due to prolonged use, improper maintenance, or impact damage.
Misalignment: Improper installation or misalignment of the kick starter mechanism can result in noise when the kick starter is used. It's essential to ensure that all components are correctly aligned and installed according to the manufacturer's specifications.
If you notice unusual or excessive noise coming from your motorcycle's kick starter, it's advisable to have it inspected by a qualified motorcycle mechanic. They can diagnose the exact cause of the noise and perform any necessary repairs or adjustments to ensure proper operation of the kick starter system.
