Tools and Materials Needed

  • Spark plug socket
  • Ratchet wrench
  • New spark plug (NGK BR9ECM or equivalent)
  • Torque wrench
  • Anti-seize compound

Step-by-Step Guide

Step 1: Prepare Your Bike

Ensure your RM85 is on a stable surface and the engine is cool to the touch. Disconnect the spark plug cap by pulling it straight off the plug.

Step 2: Remove the Old Spark Plug

Use the spark plug socket and ratchet wrench to carefully unscrew the old spark plug. Turn counterclockwise until it is free from the engine.

Step 3: Inspect the Old Spark Plug

Check the old spark plug for signs of wear or damage. A worn plug can indicate other engine issues. If the plug is oily or has excessive carbon build-up, it may be time to check your engine's fuel mixture or oil ratio.

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 plug into the engine by hand to avoid cross-threading. Once hand-tight, use the torque wrench to tighten the plug to the manufacturer's specifications (typically around 18 ft-lbs for the RM85).

Step 5: Reattach the Spark Plug Cap

Firmly press the spark plug cap back onto the new spark plug until it clicks into place. Ensure it is secure to prevent misfires.
