Shop parts for a 2019 Kawasaki KX65 Dirt Bike.

Changing the oil in your 2019 Kawasaki KX65 is a crucial part of regular maintenance that will keep your dirt bike running strong and reliable, whether you're tackling trails or racing laps. Follow the steps below for a smooth, mess-free oil change tailored specifically for your KX65.

Tools and Supplies Needed

  • 10mm or 12mm socket and ratchet (for drain plug, confirm the size fits your drain bolt)
  • Oil drain pan
  • Funnel
  • Shop rags
  • Measuring cup (with milliliter markings)
  • New transmission oil (Kawasaki recommends 10W-40 or 80W gear oil–always check your owner’s manual for approved type)
  • Torque wrench (optional, for precise tightening)
  • Clean rubber gloves (optional)

Before You Begin

  • Run the engine for a minute or two to warm the oil–warm oil drains faster and more completely.
  • Put your bike on a stand or level surface to keep it upright.
  • Have all your supplies ready and within reach.

Step-by-Step Oil Change Process

  1. Clean the Area:
    • Before starting, clean around the fill cap and drain plug to prevent any dirt from entering the transmission once they’re removed.
      Dirt can quickly damage internal gears if it enters with the new oil.
  2. Remove the Oil Fill Cap:
    • This allows oil to drain easily by letting air flow in as the oil flows out.
  3. Drain the Old Oil:
    • Place your oil drain pan under the drain bolt (on the bottom side of the engine case).
    • Use your socket and ratchet to carefully loosen and remove the drain bolt.
    • Allow all the oil to drain out. Be patient–wait 5 to 10 minutes for a complete drain.
  4. Inspect and Clean the Drain Plug:
    • Check the drain plug for metal flakes and wipe it clean. If the crush washer looks worn, replace it to prevent leaks.
  5. Reinstall and Tighten the Drain Plug:
    • Screw in the drain plug by hand to avoid cross-threading, then tighten with your socket to snug (not excessive) tightness.
    • If using a torque wrench, tighten to 11 foot-pounds (15 Nm) as specified for similar Kawasaki models.
    • Do not overtighten–excessive force can strip the threads on the case or plug.
  6. Measure and Add Fresh Oil:
    • For the 2019 KX65, the oil capacity is 0.5 quarts (500 milliliters).
    • Use your measuring cup to pour the correct amount of oil into the engine via the fill hole using a funnel.
  7. Check the Oil Level:
    • With the bike upright and level, check the oil sight glass on the side of the case–the oil should sit three-quarters up the glass when at the proper level.
    • Add small amounts if needed, being careful not to overfill.
  8. Reinstall the Fill Cap:
    • Once the oil is at the proper level, screw the fill cap back on snugly by hand.
  9. Start and Inspect:
    • Start your KX65 and let it idle for a minute.
    • Turn it off and check again for leaks around the drain plug and fill cap.
    • Double check the oil level–add more if needed but do not exceed the recommended capacity.

2019 Kawasaki KX65 Specific Tips

  • The KX65 uses a simple screw-in drain plug and a fill cap–there is no oil filter on this 2-stroke model to worry about cleaning or replacing.
  • Be particularly careful not to let dirt fall into the fill hole–always clean thoroughly before opening.
  • The oil sight glass is a convenient way to confirm correct fill; aim for the oil to sit at about the three-quarters mark with the bike upright and not leaning.
  • Do not overtighten the drain bolt or fill plug–both thread into aluminum, which can strip easily.

Disposal and Clean-Up

  • Pour used oil into a sealed container and take it to a recycling center or hazardous waste drop-off–never pour it into drains or onto the ground.
  • Wipe up any spills on your bike, stand, or floor to prevent slicks and environmental harm.

Summary

  • Changing the oil in the 2019 Kawasaki KX65 is straightforward: drain the old oil, refill with 0.5 quarts (500 mL) of fresh oil, and ensure a snug (not over-tightened) fit for all plugs and caps.
  • Always clean around the fill area, use the sight glass for level checks, and dispose of oil responsibly.
  • Following this process keeps your KX65’s transmission working smoothly and extends the bike’s life on MotoSport.com–adventures and beyond.
