Tools and Materials Needed

  • Spark plug socket
  • Ratchet wrench
  • New spark plug (NGK BPR7HS recommended)
  • Torque wrench
  • Anti-seize compound (optional)

Step-by-Step Guide

1. Prepare Your ATV

Ensure your Suzuki LT80 is on a flat surface and the engine is cool to prevent burns. Disconnect the spark plug wire by pulling it off the spark plug cap.

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 loose enough to remove by hand.

3. Inspect the Old Spark Plug

Check the old spark plug for signs of wear or damage. A worn spark 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.

4. Install the New Spark Plug

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

5. Reconnect the Spark Plug Wire

Attach the spark plug wire back onto the new spark plug, ensuring it is securely connected.
