Tools and Materials Needed
- Spark plug socket wrench
- Ratchet
- New spark plug (NGK B9ES is recommended for the KDX250)
- Gap tool
- Anti-seize compound (optional)
Steps to Change the Spark Plug
- Ensure Safety: Make sure the engine is cool to prevent burns. Disconnect the spark plug wire by pulling on the boot, not the wire itself, to avoid damage.
- Remove the Old Spark Plug: Use the spark plug socket wrench and ratchet to carefully unscrew the old spark plug from the engine. Turn counterclockwise until it is free.
- Check the Spark Plug Gap: Before installing the new spark plug, use a gap tool to ensure the gap is set to the manufacturer's specification, which is typically 0.7-0.8mm for the KDX250.
- Install the New Spark Plug: If desired, apply a small amount of anti-seize compound to the threads of the new spark plug. Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the socket wrench to snug it up, but do not over-tighten.
- Reconnect the Spark Plug Wire: Push the spark plug wire boot back onto the new spark plug until it clicks into place.
