Changing the oil in your 2019 Kawasaki KLX110 is a straightforward but critical maintenance task that preserves engine performance, ensures longevity, and offers a great introduction to DIY dirt bike care. Below is a detailed, model-specific guide to support MotoSport.com customers in keeping their KLX110s running perfectly.

Tools and Supplies Needed

  • 3/8” Ratchet with Extension
  • 8mm, 12mm, and 17mm Sockets
  • Torque Wrench
  • Oil Drain Pan
  • Shop Rags
  • New Oil Filter (optional; KLX110 uses a filter screen, but check and clean/reuse as needed)
  • 1 Liter (32 oz) of 10W-40 Motorcycle Oil
  • Funnel

Step-by-Step Oil Change Instructions

  1. Prepare Your Bike and Workspace
    • Ensure the bike is upright on a flat, stable surface.
    • Warm up the engine for 2–3 minutes. This helps circulate debris and makes the oil flow more freely for draining

      .
  2. Remove the Skid Plate
    • Using your 8mm socket, undo the bolts on each side of the skid plate. Then use the 12mm socket to remove the two bolts located behind the plate

      .
    • Gently lift off the skid plate to access the drain plug underneath.
    • Owner’s Call-Out: If you just ran the engine, be cautious—the exhaust and engine case will be hot

      .
  3. Remove the Oil Fill Cap
    • This step allows the oil to drain more quickly by breaking the vacuum inside the crankcase

      .
  4. Drain the Old Oil
    • Position your drain pan beneath the engine.
    • Using a 17mm socket, remove the drain bolt located at the underside of the engine

      .
    • Allow the oil to drain completely (a few minutes).
    • Inspect and clean the drain plug. Check its sealing washer for wear and replace if necessary.
  5. Check or Replace the Oil Filter Screen (optional)
    • The KLX110 uses a simple filter screen rather than a full oil filter. To service it:
      • Locate and remove the filter cover with the appropriate socket.
      • Take out the metal screen, rinse in clean solvent, dry thoroughly, and reinstall.
      • If your bike has an aftermarket or updated filter, follow those specific instructions.
    • Owner’s Call-Out: Kawasaki recommends filter screen cleaning every other oil change or as needed based on riding conditions.
  6. Reinstall the Drain Plug
    • Thread the 17mm drain plug in by hand to avoid cross-threading, then tighten with a torque wrench to manufacturer specifications (usually about 13 ft-lb for KLX110, check your manual to confirm)

      .
  7. Refill with Fresh Oil
    • Insert a funnel into the fill port.
    • Pour in 0.9 to 1.0 liters (32 oz) of 10W-40 motorcycle oil for a full change. Use only 0.9 liters if not changing/cleaning the filter screen

      .
  8. Check the Oil Level
    • Replace and tighten the oil fill cap.
    • Start the bike and let it idle for 2–3 minutes; shut off and wait a couple more minutes.
    • With the bike standing fully upright, check the oil level through the sight glass—it should be between the upper and lower marks.
    • Add or remove oil as needed to bring the level into spec

      .
  9. Reinstall the Skid Plate
    • Re-attach the skid plate with the original bolts. Double-check all bolts for tightness

      .
  10. Final Checks and Clean-Up
    • Wipe away any residual oil from the engine case and bolts.
    • Dispose of used oil responsibly by taking it to an approved recycling facility.

2019 KLX110 Owner-Specific Notes

  • The KLX110 engine has no spin-on oil filter, only a screen. Regular cleaning of this screen is sufficient under typical use

    .
  • Always verify oil capacity; overfilling can cause increased crankcase pressure and oil leaks

    .
  • The bike’s manual recommends the first oil change at 5 hours and every 50 hours of riding thereafter, but consider more frequent changes in harsh or dusty environments

    .
  • Use street-legal, wet clutch compatible motorcycle oil for optimum clutch function and transmission protection.
  • Monitor the torque on drain and skid plate bolts; overtightening can strip threads or crack the case.

Summary

Regular oil changes are the most affordable insurance against unnecessary engine wear. Servicing your 2019 Kawasaki KLX110 yourself with quality supplies from MotoSport.com takes under 30 minutes, saves money, and delivers confidence and mechanical connection to your bike.
