Step-by-Step Guide
Step 1: Prepare Your ATV
Ensure your Yamaha Raptor 90 is on a flat, stable surface. Turn off the engine and let it cool down completely to avoid burns.
Step 2: Locate the Spark Plug
The spark plug is located on the engine's top side. Remove any panels or covers if necessary to access it.
Step 3: 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.
Step 4: Inspect the Old Spark Plug
Check the old spark plug for signs of wear or damage. This can provide insights into the engine's condition. If the plug is oily or has excessive carbon buildup, further engine inspection may be needed.
Step 5: Install the New Spark Plug
Apply a small amount of dielectric grease to the new spark plug's threads. Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the torque wrench to tighten it to the manufacturer's specified torque setting.
Step 6: Reassemble and Test
Reattach any panels or covers you removed earlier. Start the engine to ensure it runs smoothly with the new spark plug.
