Tools and Materials Needed

  • Spark plug socket
  • Ratchet wrench
  • New spark plug (NGK C7HSA recommended)
  • Torque wrench
  • Anti-seize compound

Step-by-Step Guide

Step 1: Prepare the Bike

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

Step 2: Remove the Old Spark Plug

Use the spark plug socket and ratchet wrench to carefully unscrew the old spark plug. Turn counterclockwise until it is free from the engine.

Step 3: Inspect the Old Spark Plug

Check the old spark plug for signs of wear or damage. A worn plug can indicate other engine issues. If the plug is oily or has excessive carbon build-up, further inspection of the engine may be necessary.

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 plug to the manufacturer's specifications, typically around 18 ft-lbs for the XR70.

Step 5: Reattach the Spark Plug Wire

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