What are the symptoms of a broken scooter clutch?

There will be symptoms such as the car being unable to start or having difficulty starting, difficulty shifting gears, gear grinding or inability to stop, and the clutch overheating. Additionally, there may be shaking and vibration of the entire vehicle during startup, especially when idling and gradually releasing the clutch pedal in low gear, resulting in continuous jerking. When the clutch pedal is slightly depressed, the inner end face of the release bearing just touches the release lever, and the clutch makes a continuous "click, click, click" sound. There may also be noise accompanied by shaking when engaging during startup or disengaging while moving. Below is additional information: 1. Clutch working principle: The car clutch is located in the flywheel housing between the engine and the transmission. The clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. While driving, the driver can press or release the clutch pedal as needed to temporarily disconnect or gradually engage the engine and transmission, thereby cutting off or transmitting the power input from the engine to the transmission. 2. Friction clutch: Currently, the most widely used in cars is the spring-loaded friction clutch (referred to as the friction clutch). The torque generated by the engine is transmitted to the driven plate through the friction between the flywheel, pressure plate, and the contact surface of the driven plate. When the driver presses the clutch pedal, the diaphragm spring's large end moves the pressure plate backward through the transmission of mechanical parts, separating the driven part from the driving part.
I've been commuting with my scooter for years, and the symptoms of a failing clutch can be really frustrating. I remember recently, when starting the car, it buzzed loudly, the RPM soared but the speed was as slow as a snail, as if it was slipping, especially when going uphill—it just couldn't make it. Acceleration was also jerky, feeling like the power was stuck, not as smooth as usual. From time to time, I'd hear a creaking friction noise, especially when decelerating or shifting gears. Even worse, one time I smelled a burning odor, which scared me into stopping to check immediately. This made me nervous on the road, afraid of losing control and causing an accident. Later, I went to the repair shop and replaced the clutch plates to fix it. Since then, I've developed a habit of doing a simple monthly check on the clutch connection and sounds to ensure safe driving. Spotting these small signs early helped avoid bigger problems.
