Tools and Materials Needed

  • Ratchet or socket wrench
  • Torque wrench (optional but recommended)

Step-by-Step Guide

Step 1: Prepare Your Bike

Ensure your CRF70F is on a stable surface and the engine is cool to the touch. Disconnect the spark plug wire by pulling it straight off the plug.

Step 2: Remove the Old Spark Plug

Use the spark plug socket wrench to loosen and remove the old spark plug. Turn counterclockwise until the plug is free. Inspect the old plug for any signs of wear or damage, which can indicate engine issues.

Step 3: Install the New Spark Plug

Take the new spark plug and thread it into the cylinder head by hand to avoid cross-threading. Once hand-tight, use the socket wrench to snug it up. If using a torque wrench, tighten to the manufacturer's specification of 9 ft-lbs.

Step 4: Reattach the Spark Plug Wire

Firmly push the spark plug wire back onto the new spark plug until you feel it click into place. Ensure it's secure to prevent misfires.
