If you leave your motorcycle idle for an extended period without running the engine, several things can happen:
Battery Drain: If the motorcycle's engine is not running, the battery will gradually lose its charge. Electrical systems such as the lights, indicators, and other accessories may drain the battery over time. Eventually, the battery may become completely discharged, making it difficult or impossible to start the bike.
Fuel Degradation: Fuel sitting in the motorcycle's fuel tank for an extended period can deteriorate. The lighter components of the fuel can evaporate, leaving behind a gummy residue that can clog the fuel system and affect engine performance. It is especially problematic for carbureted motorcycles. Fuel stabilizers can help slow down the degradation process, but it is generally recommended to drain the fuel or use fresh fuel when starting the motorcycle after a long period of idleness.
Fluid Contamination: Various fluids in the motorcycle, such as engine oil, coolant, and brake fluid, can degrade or become contaminated over time. Extended periods of inactivity can lead to moisture accumulation, which can cause corrosion or other issues. It is advisable to check and, if necessary, replace the fluids before riding the motorcycle again.
Tire Flat Spots: If the motorcycle sits idle for a long time, the weight of the bike can cause the tires to develop flat spots. These flat spots can lead to an uneven ride and reduced tire performance. It's best to periodically move the motorcycle or use a stand to alleviate the weight on the tires.
Seized Components: Lack of use can cause various components to seize or become stuck. This includes the throttle, clutch, brake calipers, and other moving parts. Regular maintenance and occasional operation can help prevent these issues.
To maintain your motorcycle's health during periods of inactivity, it's generally recommended to perform regular maintenance tasks, store the bike in a cool and dry place, and periodically start and run the engine to keep the battery charged and the fluids circulating.
