What are the symptoms of a bad motorcycle starter motor?

Motorcycle starter motor is not working the most obvious symptom is that the motorcycle ignition starter does not turn, and the motorcycle cannot start. The motorcycle starter motor is what people usually refer to as the starter nowadays. It works by using an energized coil to rotate in a magnetic field, driving the starter rotor to spin. The small gear on the rotor then drives the engine flywheel to rotate, thereby turning the crankshaft and starting the engine. If it is broken, the motorcycle cannot be started. The following are the reasons for the failure to rotate or rotate slowly: The battery is dead or has insufficient power: causing the starter to not rotate or rotate slowly. Worn or improperly aligned brushes: leading to poor contact with the commutator. Dirty or damaged commutator: causing poor contact between the brushes and the commutator.
My Harley motorcycle engine failed once, with very obvious symptoms. The engine seized up and wouldn't move when starting, with no response after turning the key for a long time. While riding, the power dropped sharply, the body shook violently like an earthquake, accompanied by a grinding noise like bones rubbing together. The exhaust pipe emitted abnormal blue smoke with a strange burnt oil smell. Acceleration was also uneven, struggling even on flat roads, and reaching 30 mph was very difficult. Earlier, there were issues with difficult ignition or delayed cold starts. These signs indicated internal component wear such as pistons or cylinders. After noticing, I stopped riding immediately and had a professional mechanic inspect it to avoid worse engine damage. Regular maintenance and monitoring oil temperature can prevent similar failures, but don't attempt DIY repairs to avoid making things worse.
