If you don't start a motorcycle for a month, several things can happen due to inactivity and prolonged storage. Here are some potential issues:
Battery drain: The motorcycle's battery may lose charge over time, especially if there are any electronic systems that continue to draw power when the bike is not in use. This could lead to a dead battery, making it difficult or impossible to start the motorcycle.
Fuel deterioration: Fuel can degrade over time, particularly if it contains ethanol. As gasoline evaporates, it can leave behind a sticky residue that clogs fuel injectors or carburetors. This can result in starting difficulties or poor engine performance.
Carburetor or fuel injector problems: If the motorcycle has a carburetor, the jets and other small passages may become blocked if fuel is left sitting in them for an extended period. Similarly, fuel injectors can get clogged if the bike has a fuel injection system. This can lead to rough running or starting problems.
Tire flat spots: If the motorcycle remains stationary for a long time, the weight of the bike can cause flat spots to develop on the tires. These flat spots can affect the ride quality and may require replacement if they become severe.
Sticking brakes: If the motorcycle is stored in a damp environment or exposed to moisture, the brake components may rust and seize, causing the brakes to stick. This can make it challenging to move the bike or cause unsafe riding conditions.
To prevent or mitigate these issues, it's advisable to take some precautions when storing a motorcycle for an extended period:
Keep the battery charged: Either disconnect the battery or use a battery maintainer/charger to keep it at an optimal charge level.
Use a fuel stabilizer: Add a fuel stabilizer to the gas tank to prevent fuel degradation. Follow the manufacturer's instructions for the appropriate amount of stabilizer to use.
Consider draining the fuel: If you anticipate leaving the motorcycle unused for an extended period (e.g., several months), it may be beneficial to drain the fuel from the tank and carburetor to avoid fuel-related issues.
Store in a suitable location: Keep the motorcycle in a dry, well-ventilated area away from extreme temperatures and direct sunlight. A motorcycle cover can provide additional protection.
Check tire pressure: Inflate the tires to the recommended pressure and, if possible, periodically move the bike to avoid developing flat spots.
Lubricate moving parts: Apply a light coat of lubricant to critical components such as the chain, throttle, and cables to prevent rust and ensure smooth operation.
Before riding the motorcycle again after an extended period of inactivity, it's a good idea to inspect the bike thoroughly, check fluid levels, and perform any necessary maintenance or repairs.
