Leaving gas in a motorcycle for extended periods can have some negative consequences. Here are a few potential issues that may arise:
Fuel degradation: Over time, gasoline can break down and degrade, especially if it contains ethanol. This can result in the formation of varnish and gum deposits that can clog fuel lines, carburetors, or fuel injectors. Stale fuel may also make the engine difficult to start or cause poor performance.
Carburetor or fuel injector problems: If the motorcycle has a carburetor or fuel injection system, leaving gas in the system for an extended period can lead to problems. The fuel passages can become blocked or clogged, affecting the bike's performance and potentially requiring expensive repairs.
Corrosion: Gasoline can be corrosive, particularly when combined with moisture or condensation. If the fuel tank is not properly sealed and protected, leaving gas in it for a long time can lead to rust and corrosion inside the tank, potentially causing leaks or contaminating the fuel system.
To avoid these issues, it is generally recommended to take some preventive measures:
Stabilize the fuel: If you plan to leave your motorcycle unused for an extended period, consider using a fuel stabilizer. These additives help slow down fuel degradation and keep it fresh for longer periods. Follow the instructions provided by the manufacturer of the fuel stabilizer for the correct dosage and usage.
Empty the fuel tank: Alternatively, you can choose to drain the fuel from the motorcycle's tank and fuel lines completely. Be cautious when doing this and follow proper safety procedures. Dispose of the fuel in accordance with local regulations.
Store the motorcycle properly: If you're storing the motorcycle for an extended period, ensure it is stored in a dry, cool place away from direct sunlight. Cover the bike to protect it from dust and other contaminants.
By taking these precautions, you can help minimize the negative effects of leaving gas in a motorcycle for prolonged periods and keep your bike in better condition.
