Shop parts for a 2023 Kawasaki KLX110 Dirt Bike.

Maintaining your 2023 Kawasaki KLX110 with regular oil changes is essential for engine longevity, smooth performance, and reliable rides. Follow this comprehensive, model-specific guide for a trouble-free oil change process, proprietary for MotoSport.com customers.

Tools & Supplies Needed

  • 3/8" ratchet and extension
  • 8mm, 12mm, and 17mm sockets
  • Torque wrench
  • Oil drain pan
  • Shop rags
  • New engine oil (SAE 10W-40, JASO MA certified)
  • Oil filter (if replacing, refer to manual for part #)
  • Gloves and safety glasses
  • Funnel

Preparation Steps

  • Warm up the engine: Run the motorcycle for about 2–3 minutes. This warms the oil, allowing it to drain more completely. Stay clear of hot exhaust components during this process.
  • Turn off the engine and place the bike on a level surface. Use a stand if available to keep the KLX110 upright for accurate draining and refilling.

Step-by-Step Oil Change Procedure

  1. Remove the Skid Plate:
    • Use your 8mm socket to remove the bolts on each side of the skid plate.
    • Remove the two 12mm bolts behind the skid plate.
    • Carefully take off the skid plate and set it aside.
    Note: If the engine was running recently, be cautious; exhaust components may still be very hot.
  2. Remove the Oil Fill Cap:
    • Unscrew the oil fill cap located on the side of the engine. This step helps prevent a vacuum and allows oil to drain efficiently.
  3. Drain the Engine Oil:
    • Position your oil drain pan beneath the engine’s drain plug (bottom of the crankcase).
    • Use the 17mm socket to carefully remove the drain bolt and let all the old oil flow out.
    • Inspect the drain bolt for metal debris; clean if necessary.
  4. Replace the Oil Filter (if applicable):
    • The KLX110 does NOT use a conventional canister filter; it features a mesh oil screen that can be cleaned, but replacement is not part of every oil change. Carefully follow the manual if you choose to clean the oil screen at this time.
  5. Reinstall the Oil Drain Bolt:
    • Once the oil has finished draining, reinstall the drain bolt by hand to avoid cross-threading.
    • Tighten with your torque wrench to the manufacturer’s spec (17 Nm / 12.5 ft-lb for the 2023 KLX110), avoiding overtightening.
  6. Refill with New Oil:
    • Place a funnel into the oil fill hole.
    • Pour in 0.9 liters (0.95 US qt) of 10W-40 motorcycle oil—this is the required amount when an oil filter is not replaced.
    • If you’ve cleaned the oil screen or replaced an oil filter (if applicable), add up to 1.0 liter (1.05 US qt).
    Kawasaki’s sight glass on the right engine case assists with proper oil level confirmation.
  7. Replace the Oil Fill Cap:
    • Clean the cap and sealing surface, then screw the cap back on securely.
  8. Reinstall the Skid Plate:
    • Reattach the skid plate, tightening the 8mm and 12mm bolts to secure it.
  9. Start the Engine and Check Oil Level:
    • Start the bike and let it idle for two to three minutes, allowing oil to circulate.
    • Shut off the engine and let it sit for just a couple of minutes so the oil settles.
    • Hold your bike level and check the oil level in the sight glass—oil should be between the upper and lower lines.
    • Top up with a small amount if needed, being careful not to overfill.

KLX110 (2023) Model-Specific Callouts

  • No spin-on oil filter: The 2023 KLX110 retains an internal oil screen, not a paper element. For most owners, simply drain, refill, and ride.
  • Oil capacity is less than 1 liter. Overfilling risks engine leaks and performance issues.
  • Always use motorcycle-specific 10W-40 oil with JASO MA/MA2 certification for wet clutch compatibility.
  • Check the sight glass while the bike is held level for an accurate reading. Don’t check while it’s leaning on the kickstand.
  • If you ride in especially dusty or muddy conditions, change oil more frequently than the standard interval.
  • Reuse the drain bolt washer if in good condition, or replace if damaged to ensure a proper seal.

Disposal & Final Tips

  • Recycle the used oil responsibly at a local collection center.
  • Keep a maintenance record for future reference and resale value.

With these steps, your 2023 Kawasaki KLX110 is ready for the trails with fresh oil and optimum protection, all powered by the expertise of MotoSport.com.
