1. Prepare Your Bike
Ensure your bike is on a stable surface and the engine is cool to the touch. Disconnect the battery to prevent any accidental starts.
2. Remove the Seat and Fuel Tank
Use the appropriate tools to remove the seat and fuel tank. This will give you access to the engine and the spark plug.
3. Locate the Spark Plug
The spark plug is located on the top of the engine. Carefully remove the spark plug cap by pulling it straight off.
4. Remove the Old Spark Plug
Using a spark plug socket and ratchet wrench, turn the spark plug counterclockwise to remove it. Be gentle to avoid damaging the threads.
5. Check the New Spark Plug
Before installing, check the gap on the new spark plug using a feeler gauge. The correct gap for the 2021 Honda CRF250R is typically 0.028 to 0.031 inches. Adjust if necessary.
6. Install the New Spark Plug
Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use a torque wrench to tighten it to the manufacturer's specifications, usually around 13 ft-lbs.
7. Reassemble the Bike
Reattach the spark plug cap, ensuring it clicks into place. Reinstall the fuel tank and seat, securing them properly.
