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 off the plug cap.

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, then remove it from the engine.

Step 3: Check the New Spark Plug

Before installing, check the gap on the new spark plug using a gap tool. The correct gap for the KX80 BIG WHEEL is 0.028 inches. Adjust if necessary.

Step 4: Install the New Spark Plug

Apply a small amount of anti-seize lubricant to the threads of the new spark plug. Carefully thread it into the engine by hand to avoid cross-threading. Once hand-tight, use the spark plug socket and ratchet to snug it up – do not over-tighten.

Step 5: Reconnect the Spark Plug Wire

Firmly push the spark plug wire back onto the new spark plug until it clicks into place.
