What to Do When a Motorcycle Engine Won't Start Due to Being Too Cold?

[VonBrielle]

The solutions for a motorcycle engine that won't start due to being too cold are: 1. Check the carburetor, fuel mixture ratio, fuel level, and choke; 2. Check if the valve clearance is too small or if there is air leakage; 3. Inspect whether the high-voltage spark for ignition is strong; 4. Open the choke to force start. The reasons why a motorcycle engine won't start when too cold are: 1. Low cylinder pressure, resulting in poor atomization of the mixture provided by the carburetor or fuel pump at low temperatures, making it difficult to ignite; 2. High engine operating resistance at low temperatures. Methods to prevent a motorcycle engine from failing to start when too cold include: 1. Switch to engine oil with a lower viscosity suitable for winter use; 2. Clean carbon deposits.
