What to Do When a Motorcycle Won't Start After Sitting for a Long Time?

[McVivian]

Motorcycle sitting for several years won't start, the reasons and solutions are as follows: 1. Carburetor blockage: The gasoline inside the carburetor will evaporate and deteriorate, forming sticky substances that block the carburetor's spray holes, preventing fuel injection and causing failure to start. Simply remove the carburetor, clean it thoroughly, unclog all the spray holes inside the carburetor, and then reinstall it. 2. Battery depletion or failure: You can charge the battery with a charger; if it doesn't hold a charge, replace it with a new one. Below is some relevant information about the carburetor: 1. Working principle: The carburetor is essentially a tube with an adjustable plate called a throttle valve in the middle, used to control the airflow through the tube. 2. Definition: The carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by the engine's operation.
