Step-by-Step Guide

Step 1: Prepare Your Bike

Ensure your Cobra BM50 is on a stable surface and the engine is cool to the touch. Disconnect the spark plug wire by pulling the boot off the plug.

Using the spark plug socket and ratchet wrench, carefully unscrew the old spark plug from the engine. Take note of any oil or carbon deposits on the plug, as these can indicate engine issues.

Step 3: Check the New Spark Plug

Before installation, use the gap tool to ensure the new spark plug is gapped correctly according to the manufacturer's specifications. Apply a small amount of anti-seize compound to the threads of the new plug to prevent it from seizing in the engine.

Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the spark plug socket and ratchet to snug it down. Do not over-tighten, as this can damage the threads.
