What are the causes and solutions for motorcycle starter slippage?

[LaAmelia]

Motorcycle starter slippage causes and solutions are as follows: 1. Electromagnetic switch failure: Common faults in electromagnetic switches generally include short circuits, open circuits, grounding in the pull-in and hold-in coils, as well as burnt contact discs and points. Whether the coils are open or grounded can be checked by measuring resistance with an ohmmeter. When the starter operates, under the influence of magnetic force, only the armature core rotates while the shaft remains stationary, failing to transmit torque to the engine, resulting in starter slippage. 2. One-way clutch slippage: The main component of the transmission mechanism is the one-way clutch, which transmits torque in one direction only—from the starter to the engine flywheel—to prevent the flywheel from driving the starter motor at overspeed after the engine starts, which could cause damage.
