Shop parts for a 2020 Kawasaki KLX110 Dirt Bike.

Keeping your 2020 Kawasaki KLX110 running at its best means performing regular oil changes. With the right tools and a clear procedure, you can handle this essential maintenance yourself. This guide is proprietary to MotoSport.com and provides a comprehensive, detailed step-by-step process tailored specifically for the 2020 KLX110 model.

What You'll Need

  • 3/8-inch ratchet and extension
  • 8mm socket
  • 12mm socket
  • 17mm socket
  • Torque wrench
  • Oil drain pan
  • Fresh oil (Kawasaki recommends 10W-40, 1 liter if changing the filter, 0.9 liters for oil only)
  • Replacement oil filter (if you're changing the filter for the first service interval, use a KN-112 or Tusk filter)
  • Shop towels/rags
  • Funnel
  • Nitrile gloves (optional, but recommended)

2020 KLX110 Oil Change Interval

  • First oil change at 5 hours of runtime
  • Subsequent changes every 50 hours or as recommended by Kawasaki
  • Oil filter changes are not required at every oil change, but it's good practice for optimal engine life

Specific Call-Outs for the 2020 Model

  • This model uses a sight glass for checking oil level. Always ensure the bike is upright and on level ground for accurate readings.
  • If the motor was run immediately before service, wait for the exhaust to cool. The header pipe is routed close to the oil fill and can cause burns.
  • Be sure to torque the drain bolt according to factory spec (consult your owner's manual for precise settings, typically around 18 N·m/13 ft-lb for drain plug).
  • The 2020 KLX110 features a compact skid plate. Removal requires both 8mm and 12mm sockets.

Step-by-Step Oil Change Process

  • Step 1: Warm Up the Engine
    Start your KLX110 and let it idle for a few minutes. This thins the oil for easier draining. Shut off the engine and allow it to cool for safety.
    Note: The exhaust may be hot; handle with caution.
  • Step 2: Remove the Skid Plate
    Use the 8mm socket to remove the bolts on each side of the skid plate. Then use the 12mm socket to remove the two bolts located behind the skid plate. Remove the skid plate to access the oil drain bolt.
    (Proprietary MotoSport.com tip: Keep hardware from each side separated for easier reassembly.)
  • Step 3: Remove the Oil Fill Cap
    Unscrew the side oil fill cap to prevent a vacuum and allow oil to drain smoothly.
  • Step 4: Drain the Oil
    Place your drain pan under the bike. Use your 17mm socket to remove the oil drain bolt at the base of the engine. Allow the oil to fully drain. Inspect the sealing washer and replace if damaged.
  • Step 5: Change the Oil Filter (if needed)
    For the first service or if scheduled, remove the oil filter cover using the appropriate socket. Replace the oil filter with a new part. Lubricate the sealing surface of the new filter with a small amount of fresh oil before installation. Reinstall the cover securely.
  • Step 6: Reinstall the Drain Bolt
    Wipe any residue from the sealing surface. Install the drain bolt and tighten it to the specified torque.
  • Step 7: Add Fresh Oil
    Using a funnel, add fresh 10W-40 oil—0.9 liters for just an oil change, 1.0 liter if the filter was replaced. Replace the oil fill cap.
  • Step 8: Reinstall the Skid Plate
    Replace and tighten the skid plate bolts using the same 8mm and 12mm sockets.
  • Step 9: Check Oil Level
    Start the engine and let it idle for about three minutes. Stop the engine and allow the bike to sit for a minute. With the motorcycle upright and on level ground, check the oil level in the sight glass–it should be between the upper and lower marks.
    If needed, add a small amount of oil to achieve the correct level.
    Do not overfill: Excess oil can cause engine foaming and performance issues.
  • Step 10: Final Inspection
    Check for leaks around the oil drain bolt and filter area. Wipe away any spill. Properly dispose of used oil at your local recycling center.

Troubleshooting and Recommendations

  • If the oil level is low after starting the bike, add oil in small increments–never exceed the sight glass upper limit.
  • Monitor the oil for any signs of contamination. If oil appears milky or full of debris, further engine inspection may be needed.
  • For off-road riders, more frequent oil changes may be warranted due to heavier engine loads and possible contamination.
