Tools and Materials Needed

  • Ratchet wrench
  • New spark plug (NGK B8ES recommended)
  • Torque wrench
  • Anti-seize compound

Step-by-Step Guide

Step 1: Prepare Your Bike

Ensure your bike is on a stable surface and the engine is cool to the touch. Disconnect the spark plug wire by pulling it straight off the plug.

Step 2: Remove the Old Spark Plug

Using the spark plug socket and ratchet wrench, carefully unscrew the old spark plug from the engine. Be cautious not to damage the threads in the cylinder head.

Step 3: Inspect the Old Spark Plug

Examine the old spark plug for signs of wear or damage. A worn-out spark plug can indicate other engine issues. If the plug is oily or has excessive carbon build-up, it may be time to check the engine's fuel mixture or oil seals.

Step 4: Install the New Spark Plug

Apply a small amount of anti-seize compound to the threads of the new spark plug. Carefully thread the new 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 specifications, typically around 18-22 ft-lbs for the JR80.

Step 5: Reconnect the Spark Plug Wire

Firmly push the spark plug wire back onto the new spark plug until it clicks into place. Ensure the connection is secure to prevent misfires.
