Regular oil changes are vital to keep your 2018 Kawasaki KX65 performing at its best. This guide, proprietary to MotoSport.com, provides a robust and easy-to-follow process for changing your KX65’s oil. We’ll highlight the tools you need, each step of the process, and special tips specific to this make and model.

Tools & Materials Needed

  • 14mm socket or wrench – for the drain plug
  • Drain pan – to catch old oil
  • Cleaning rags
  • Funnel with a long hose – makes pouring new oil easier
  • Measuring cup – for accurate oil volume measurement
  • Torque wrench (optional, for drain bolt torque)
  • SAE 10W-40 transmission oil (or specified oil)
  • Zip tie (optional, to secure funnel)
  • Gloves (optional, to keep your hands clean)

Step 1: Preparation

  • Warm up the engine for 2–3 minutes to help the oil flow out smoothly. Turn the bike off and let it cool for a few minutes to avoid burns.
  • Place the motorcycle on a stable stand so it remains level during service.
  • Gather your tools and supplies within easy reach.

Step 2: Locate and Remove the Drain Plug

  • The oil drain plug is located on the bottom of the engine case. It requires a 14mm socket or wrench for removal.
  • Place the drain pan directly under the plug.
  • Slowly loosen and remove the drain bolt, keeping a firm grip as oil will begin to flow out quickly.
  • Allow the oil to drain completely. This may take a few minutes.

Step 3: Clean and Reinstall the Drain Plug

  • Inspect the drain bolt and the sealing washer for wear or damage. Replace the washer if necessary to prevent leaks.
  • Clean the drain bolt with a rag.
  • Once oil flow has stopped, reinstall the drain bolt and tighten it securely.
    • Kawasaki KX65 specific tip: The drain plug size is 14mm.
    • If using a torque wrench, tighten the drain plug to the manufacturer’s specified torque (refer to your owner’s manual, or use 11 ft-lbs if no value is available).

Step 4: Add New Oil

  • Check your owner’s manual for the specified oil quantity for the 2018 KX65. Reports and user guides recommend 0.5 quarts (or 0.5 liters) of SAE 10W-40 transmission oil for the KX65.
  • Insert the funnel with a long hose into the oil fill port. You may use a zip tie to secure the funnel to the bike for stability while pouring.
  • Slowly pour in the measured oil, pausing occasionally to avoid overfilling.
  • Use the oil-level sight glass on the engine case to monitor the level as you fill.

Step 5: Check Oil Level

  • Once the recommended amount of oil has been added, reinstall the oil filler cap.
  • Start the engine and run it for 30 seconds, then turn it off and let the oil settle for 1–2 minutes.
  • Check the level through the sight glass on the right side of the engine:
    • The oil should be midway in the window when the bike is upright and level.
    • Add more oil if the level is low. Do not exceed the maximum mark.

Step 6: Clean Up and Inspect

  • Wipe off any spilled oil from the engine and frame.
  • Dispose of the used oil responsibly at your nearest recycling center or auto parts store.
  • Check for oil leaks around the drain plug and oil fill port after your first ride.
