Regular oil changes are crucial maintenance you can easily tackle at home and mastering this task builds your confidence and connection with your machine. The following step-by-step guide, proprietary to MotoSport.com, covers the proper tools, complete process, and model-specific tips so your KLX110L stays race-ready.

Tools & Supplies Needed

  • 3/8” ratchet and extension
  • 8mm, 12mm, 17mm sockets
  • Torque wrench
  • Oil drain pan
  • Shop towels or rags
  • Fresh engine oil (10W-40, JASO MA compliant; check owner's manual for type/amount)
  • Oil filter (if replacing; OEM recommended)
  • Funnel
  • Gloves (optional, but recommended)

Step-by-Step Oil Change Instructions

  1. Warm the Engine
    • Start the bike and let it idle for 2–3 minutes to warm the oil. This helps it drain faster and removes more contaminants. Turn off the engine before you begin.
  2. Remove the Skid Plate
    • Use the 8mm socket to remove the bolts on both sides of the skid plate and the two 12mm bolts behind it. Set the skid plate and bolts aside. Note: The exhaust will be hot if you just ran the bike—work carefully to avoid burns

      .
  3. Remove the Oil Fill Cap
    • Twist off the oil fill cap to allow the crankcase to vent. This ensures a smooth, complete drain

      .
  4. Drain the Old Oil
    • Place your oil drain pan beneath the engine's drain bolt.
    • Use the 17mm socket to loosen and remove the drain bolt. Allow all old oil to pour out (give it at least 5 minutes to fully drain).
    • Inspect and clean the drain bolt and its crush washer for wear or debris—replace the washer if damaged.
  5. Replace or Clean the Oil Filter (if equipped)
    • Disconnect the old oil filter if your maintenance interval calls for a change. Make sure to lube the seal of the new filter with some fresh oil before installation for a tight seal. Replace the filter and tighten per the manufacturer's specified torque

      .
  6. Reinstall Drain Plug
    • Once oil is completely drained and any filter replaced, reinstall the drain plug by hand to avoid cross-threading, then finish with a torque wrench set to Kawasaki specifications for your model (consult owner’s manual or service guide).
  7. Add Fresh Oil
    • Insert a funnel into the oil fill hole and pour in the new oil. The KLX110L typically takes around 0.9 to 1.1 liters of oil, depending on whether you changed the filter

      .
    • For just a basic oil change, use about 0.9 liters. For a full change including filter, use up to 1.1 liters. Consult your owner’s manual for your model’s exact capacity

      .
  8. Check Oil Level
    • Replace and tighten the oil fill cap.
    • Start the engine and let it idle for about 3 minutes. Shut it off and wait 2–3 minutes for oil to settle.
    • With the bike upright on level ground (not on its side stand), check the oil level in the sight glass on the engine. The oil should be between the upper and lower marks

      .
    • Add or drain small amounts of oil if needed to hit the correct level

      .
  9. Clean Up and Reinstall Skid Plate
    • Wipe away any spilled oil. Reinstall the skid plate with its bolts and torque to spec.
    • Dispose of old oil and filter responsibly at a recycling facility.

2023 Kawasaki KLX110L-Specific Tips and Notes

  • The 2023 KLX110L uses a horizontal single-cylinder engine design—watch your knuckles when accessing bolts around the skid plate and drain bolt location.
  • There is no cartridge-style oil filter on standard models, but always check your engine’s side cover and verify by VIN if your submodel features a filter screen that should be cleaned with each oil change.
  • Overfilling can cause excess crankcase pressure; always check the oil window carefully after warming and waiting a few minutes for the oil to settle.
  • Kawasaki recommends JASO MA-rated 10W-40 motorcycle oil for optimal clutch and engine protection—avoid car oils that may contain friction modifiers.
  • Always ensure the bike is upright when checking oil; the sight glass is not accurate on the side stand.
