- Ensure Safety: Make sure the engine is cool to the touch to prevent burns. Turn off the ignition and remove the key.
- Locate the Spark Plug: The spark plug is located on the right side of the engine. You may need to remove the seat or side panel for better access.
- Remove the Spark Plug Cap: Gently pull the spark plug cap off the spark plug. Be careful not to damage the cap or the wire.
- Remove the Old Spark Plug: Use the spark plug socket wrench to unscrew the old spark plug. Turn counterclockwise until it is completely removed.
- Inspect the Old Spark Plug: Check the old spark plug for signs of wear or damage. This can provide insight into the engine's condition.
- Install the New Spark Plug: Insert the new spark plug into the socket and carefully thread it into the engine by hand to avoid cross-threading. Once hand-tight, use the wrench to tighten it securely. If using a torque wrench, tighten to the manufacturer's specifications.
- Reattach the Spark Plug Cap: Push the spark plug cap back onto the new spark plug until it clicks into place.
