First change the engine oil, and empty the fuel tank into an approved petrol container using a commercially available hand siphon or an equivalent method. If your motorcycle use a iron fuel-tank, spray the inside of the tank with an aerosol rust-inhibiting oil. Not forget to reinstall the fuel fill cap on the fuel-tank.
If your motorcycle storage will last more than one month, and if your motorcycle is using carburetors you need to drain the carburetors – this is especially important if you use fuel containing ethanol, this will assure working and proper performance after storage.
To prevent corrosion in the cylinder, perform the following:
- Remove the spark plug cap from the spark plug. Using tape or string, secure the cap to any convenient plastic part so it is positioned away from the spark plug.
- Remove the spark plug from the engine and store it in a safe place. Do not connect the spark plug to the spark plug cap.
- Pour 15 to 20cc of clean engine oil into the cylinder and cover the spark plug hole with a piece of cloth.
- Crank the engine several times to distribute the oil.
- Reinstall the spark plug and spark plug cap.
- Remove the battery. Store in an area protected from extreme temperatures and direct sunlight.
- Wash and dry the motorcycle. Wax all painted surfaces. Coat chrome with rust-inhibiting oil or special chrome protection wax.
- Lubricate the drive chain. Use WD-40 or any serious chain lubrication product
- Inflate the tires to their recommended pressures. Place the motorcycle on blocks to raise both tires off the ground.
- Cover the motorcycle, and please don't use plastic or other coated materials, and store in an cool area, free of dampness with as less possible temperature variations
- Do not store the motorcycle in direct sunlight.
