1. Safety Precautions:
Before starting any work, make sure the scooter is turned off and the ignition key is removed to avoid any accidental ignition.
2. Locate the Engine Cover:
- The spark plug on the Peugeot Elystar 125 is usually located on the left side of the scooter.
- Look for the cylinder head cover, which is typically a black or silver metallic cover.
3. Remove the Engine Cover:
- Some models may require the removal of a few bolts or screws to access the engine cover.
- Unscrew these fasteners and carefully remove the engine cover.
4. Spark Plug Location:
- Once the engine cover is removed, you will see the cylinder head.
- The spark plug is usually located on the top of the cylinder head.
5. Identify the Spark Plug:
- The spark plug is a small, cylindrical-shaped component with a ceramic insulator and a metal electrode at the end.
- It is typically connected to a spark plug wire or a coil pack.
6. Disconnect the Spark Plug Wire (if applicable):
- If the spark plug has a separate spark plug wire, gently pull the wire cap off the spark plug to disconnect it.
- Be careful not to damage the spark plug wire or its connector.
7. Remove the Spark Plug:
- Use a spark plug wrench or socket to loosen and remove the spark plug from the cylinder head.
- Be gentle and avoid applying excessive force.
8. Inspect the Spark Plug:
- Once removed, inspect the spark plug for signs of wear or damage.
- The electrode should be clean and not excessively worn or eroded.
- Replace the spark plug if necessary.
9. Reinstallation (if Applicable):
- If you replaced the spark plug, carefully screw the new spark plug into the cylinder head by hand to avoid cross-threading.
- Use the spark plug wrench to tighten the spark plug until it is snug, but do not overtighten it.
10. Reconnect the Spark Plug Wire (if applicable):
- If the spark plug has a separate spark plug wire, reconnect the wire by firmly pushing the wire cap onto the spark plug.
11. Reinstall the Engine Cover:
- Replace the engine cover and secure it using the bolts or screws you removed earlier.
- Tighten these fasteners securely.
12. Final Check:
- Double-check that all connections are secure and the spark plug wire is properly attached before starting the scooter.
Remember that if you are not comfortable performing these tasks or if you encounter any difficulties, it's best to seek assistance from a qualified mechanic or refer to your scooter's service manual for specific instructions and safety guidelines.
