Yes, motorcycle gas can go bad if it is left unused for an extended period of time. Gasoline contains volatile compounds that can evaporate over time, leading to a loss of combustibility. This process is known as fuel degradation.
When gasoline degrades, it can cause various issues with your motorcycle's engine and fuel system. Here are a few problems that can occur:
Reduced Performance: Stale gas can lead to decreased engine performance, making it difficult to start the motorcycle or causing it to run poorly.
Clogged Fuel System: Gasoline can leave behind residue and varnish-like deposits as it evaporates. These deposits can clog fuel filters, fuel injectors, and carburetors, affecting the flow of fuel and causing issues with fuel delivery.
Corrosion: Over time, the ethanol content in gasoline can attract moisture from the air, leading to corrosion in the fuel system components. This can cause further damage to the fuel lines, tanks, and other parts.
To prevent these problems, it is recommended to take certain precautions if you plan to store your motorcycle for an extended period without riding it:
Use Fuel Stabilizer: Adding a fuel stabilizer to your motorcycle's gas tank before storage can help prolong the life of the fuel and prevent it from deteriorating.
Fill the Tank: Keeping the gas tank full helps reduce the amount of air space inside, minimizing the chances of moisture buildup and reducing the rate of fuel degradation.
Run the Engine: If possible, start the motorcycle and let it run for a few minutes every couple of weeks. This helps circulate fresh fuel through the system and prevents the buildup of stale gas.
By taking these precautions, you can help preserve the quality of the gas in your motorcycle and maintain its overall performance. If you suspect that your gas has gone bad, it is advisable to drain the old fuel and replace it with fresh gasoline before attempting to start the motorcycle.
