If you never start a motorcycle during the winter and leave it sitting idle for an extended period of time, several issues may arise:
Battery Drain: The motorcycle's battery can gradually lose charge over time, especially in colder temperatures. If the battery voltage drops too low, it may become completely discharged, and you might need to jump-start or replace the battery.
Fuel System Problems: Fuel left sitting in the motorcycle's tank and fuel lines for an extended period can lead to issues like fuel degradation and varnish buildup. This can clog the fuel system, including the carburetor or fuel injectors, and result in starting problems or poor engine performance.
Carburetor Issues: Carbureted motorcycles are particularly susceptible to problems when left unused for a long time. If fuel remains in the carburetor without being burned off, it can lead to varnish or gum deposits, blocking the small passages and jets. This can cause the motorcycle to run poorly or not start at all.
Oil Deterioration: The oil in the engine can degrade over time, especially if the motorcycle isn't running. The combustion byproducts and moisture that accumulate in the oil can cause corrosion and reduce its effectiveness as a lubricant. It's generally recommended to change the oil before storing the motorcycle for a long period.
Tire Issues: Tires can develop flat spots or lose air pressure if the motorcycle remains stationary for an extended period. It's advisable to keep the tires properly inflated and consider using a stand or periodically moving the motorcycle to prevent flat-spotting.
To mitigate these issues, it's recommended to take certain precautions if you plan not to start your motorcycle during the winter. These include:
Battery Maintenance: Keep the battery charged by using a battery maintainer or trickle charger specifically designed for motorcycles. This helps to prevent battery drain and ensures it remains in good condition.
Fuel Stabilization: Add a fuel stabilizer to the tank before storing the motorcycle. This helps prevent fuel degradation and varnish buildup in the fuel system.
Carburetor Preparation: If your motorcycle has a carburetor, consider draining the fuel from the carburetor bowls to prevent varnish buildup. Consult your motorcycle's manual for specific instructions.
Storage Location: Store the motorcycle in a dry and well-ventilated area to minimize moisture-related issues. A cover can also help protect it from dust and debris.
Periodic Maintenance: Perform regular maintenance tasks such as oil changes, lubrication, and inspection of critical components before storing the motorcycle for an extended period.
Remember, it's always a good idea to consult your motorcycle's owner manual for manufacturer-recommended storage procedures specific to your model.
