What causes a motorcycle to fail to start after it has been running hot and stalls?

[OColin]

Here are the reasons why a motorcycle may fail to start: Damaged ignition components: If the motorcycle's electric start fails but the kick start works normally, it is usually due to weak high-voltage spark caused by damaged ignition components. First, try replacing the ignition coil. If that doesn't work, replace the ignition module. If the issue persists, check whether the trigger coil of the magneto is too far from the rotor's trigger head—try adjusting it slightly closer. Also, inspect whether the magneto rotor has weak magnetism or a faulty coil. High oil viscosity: There are various types of engine oil. In winter, choose oils that maintain low viscosity in colder temperatures. During winter, the low temperatures cause engine oil to thicken, increasing engine resistance and making it harder to start.
