Tools and Materials Needed

  • 3/8-inch ratchet and extension
  • 8mm, 12mm, and 17mm sockets
  • Torque wrench
  • Oil drain pan
  • Funnel
  • Rags (for cleanup)
  • Replacement oil filter (K&N KN-112 or equivalent, optional but recommended)
  • Fresh engine oil (1 liter of 10W-40, JASO MA approved)
  • Lifter stand (optional, helps keep the bike upright and level)

Important Oil Change Intervals

  • First oil change after 5 hours of engine time
  • Then every 50 hours of use for ongoing maintenance

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    • Start the KLX110 and let it idle for about 2-3 minutes. This helps the oil flow out smoothly by thinning it, ensuring contaminants are removed efficiently. Be mindful: engine and exhaust will be hot.
  2. Remove the Skid Plate
    • Use the 8mm socket to remove the bolts on each side of the skid plate.
    • Next, use the 12mm socket to remove the two larger bolts behind the skid plate. Remove the plate for clear access to the drain bolt.
  3. Locate and Remove the Oil Fill Cap
    • Unscrew the oil fill cap. This allows air in and helps the oil drain out smoothly.
  4. Position the Oil Drain Pan
    • Slide a drain pan underneath the engine to catch all the old oil.
  5. Remove the Drain Bolt
    • Use the 17mm socket to remove the oil drain bolt (located underneath the bike). Allow all oil to fully drain out. This may take several minutes.
    • Inspect the drain plug’s sealing washer or O-ring. Replace if worn or damaged.
  6. Change the Oil Filter (Optional)
    • If changing the filter (recommended at least every other change), remove it carefully. Replace with a new filter (K&N KN-112 or approved equivalent).
    • Wipe down the filter mating surface inside the cover before installing the new filter.
  7. Reinstall the Drain Bolt
    • Once drained, reinstall the drain bolt. Use a torque wrench to snug it to Kawasaki’s specification (typically around 18 ft-lb, verify in your owner’s manual).
    • Clean up any oil residue before continuing.
  8. Refill with Fresh Oil
    • Place a funnel in the oil fill hole. For a full change with filter, pour in 1 liter of 10W-40 motorcycle oil. If not changing the filter, use 0.9 liters.
    • Replace the oil cap securely.
  9. Start the Engine and Check Oil Level
    • Start the bike and let it idle again for 2-3 minutes to circulate the oil.
    • Turn off the engine and let it sit upright on a level surface for a minute. Check the oil level using the sight glass, located on the right engine case. Oil should be between the upper and lower marks.
    • Add a bit more oil if needed, but don’t overfill.
  10. Reinstall the Skid Plate
    • Bolt the skid plate back onto the frame using the 8mm and 12mm bolts.
  11. Dispose of Used Oil Responsibly
    • Take your used oil and old filter to an appropriate recycling center.

2018 Kawasaki KLX110 Model-Specific Tips

  • The 2018 KLX110 does not use a traditional spin-on filter but an internal cartridge-type filter. Always check the compatibility if replacing it.
  • Use the correct oil specification (JASO MA, 10W-40). Avoid oils with friction modifiers, as they can impair clutch performance.
  • If the bike is frequently raced or ridden in dirty/dusty conditions, change the oil even more frequently than the standard interval.
  • Always ensure the motorcycle is perfectly vertical when checking the oil level. Leaning it on the kickstand can give an inaccurate reading.

Final Thoughts

  • Changing the oil on your 2018 Kawasaki KLX110 is simple, cost-effective, and essential for engine longevity. Set a reminder based on your riding hours or conditions and perform this maintenance with confidence.
