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

Using the spark plug socket and ratchet wrench, carefully unscrew the old spark plug from the engine. Be cautious not to damage the threads in the cylinder head.

Before installation, check the gap on the new spark plug using a gap tool. The correct gap for the 1985 Honda CR250 is typically around 0.6mm to 0.7mm. Adjust if necessary.
