Step-by-Step Guide

Step 1: Prepare Your Bike

Ensure your bike is on a stable surface and the engine is cool. Disconnect the battery to prevent any accidental starts.

Step 2: Remove the Seat and Fuel Tank

Use a wrench to remove the bolts securing the seat. Once the seat is off, proceed to remove the fuel tank by disconnecting the fuel line and unscrewing the mounting bolts. This will give you access to the spark plug.

Step 3: Remove the Old Spark Plug

Locate the spark plug cap and gently pull it off. Use the spark plug socket and ratchet wrench to unscrew the old spark plug. Be careful not to damage the threads in the cylinder head.

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 spark plug into the cylinder by hand to avoid cross-threading. Once hand-tight, use a torque wrench to tighten it to the manufacturer's specifications.

Step 5: Reassemble the Bike

Reconnect the spark plug cap, ensuring it clicks into place. Reattach the fuel tank and seat, securing all bolts tightly. Reconnect the battery.
