Washing and storage

WASHING THE BIKE STORING THE BIKE

SHERCO advises you to wash your 250-300 SEF/R as often as possible in order to maintain it in good working order and prolong its life.

1. Cover the end of the exhaust silencer and the air filter (plastic bag, special cover or a special cap).
2. To degrease the engine, apply a degreaser, clean with a brush then rinse the engine with a water hose.
3. Wash the rest of the vehicle with hot soapy water.
4. Rinse with clear water.
5. Dry with a chamois or a clean, soft cloth.
6. Clean the chain and lubricate it with a special chain lube.
7. When the cleaning is finished, remove the air filter and exhaust protection, Start the engine and let it run atidle for a few minutes.

Avoid using high pressure equipment which may cause water to leak into the bearings and fork seals and cause serious damage. Use an average strength detergent rather than a strong detergent.

Before storing the vehicle Long-Term (more than 2 months), follow these instructions :

1. Wash the whole bike.
2. Empty the fuel tank.
3. Remove the spark plug and inject a protective spray inside the engine through the hole in the cylinder. Install the spark plug. Cycle the engine a few revolutions to apply a protective film on the cylinder walls.
4. Remove the battery ( p.52)
5. Charge the battery ( p.53)
6. Lubricate all cables with a spray lubricant.
7. Jack the motorcycle up so that the wheels are off the ground.
8. Cover the exhaust outlet with a plastic bag to prevent moisture from entering.
9. Spray a protective oil film on all unpainted metal surfaces of the motor and also on the electrical wiring.
10. Cover the motorcycle with a cover.

RECOMMISSIONING AFTER STORAGE
