Step 1: Locate the Spark Plug

The spark plug on the 1987 Honda TRX70 is located on the engine's top side. Ensure the ATV is turned off and cooled down before starting the process.

Gently pull the spark plug cap off the plug. Be careful not to damage the wire connected to the cap.

Step 3: Remove the Old Spark Plug

Using the spark plug socket wrench, carefully unscrew the old spark plug. If it's tight, use a socket wrench extension for better leverage. Once loose, remove it by hand.

Take the new spark plug and carefully thread it into the engine by hand to avoid cross-threading. Once hand-tight, use the spark plug socket wrench to secure it. Do not over-tighten.
