Tools and Materials Needed

  • Spark plug socket
  • Ratchet wrench
  • New spark plug (NGK BR9EG or equivalent)
  • Torque wrench
  • Anti-seize compound (optional)

Step-by-Step Guide

1. Preparation

Ensure the engine is cool to prevent burns. Place the bike on a stable stand to keep it upright and secure.

2. Remove the Old Spark Plug

Locate the spark plug on the right side of the engine. Remove the spark plug cap by pulling it straight off. Use the spark plug socket and ratchet wrench to carefully unscrew and remove the old spark plug.

3. Inspect the Old Spark Plug

Check the old spark plug for signs of wear or damage. A worn or fouled spark plug can indicate other engine issues. If the plug is oily or blackened, it may suggest a rich fuel mixture or oil leakage.

4. Install the New Spark Plug

Before installing the new spark plug, apply a small amount of anti-seize compound to the threads if desired. This can help prevent the plug from seizing in the cylinder head. Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the torque wrench to tighten the spark plug to the manufacturer's specified torque setting, typically around 18 ft-lbs.

5. Reattach the Spark Plug Cap

Firmly press the spark plug cap back onto the new spark plug until it clicks into place. Ensure it is securely attached to prevent misfires.
