Regular oil changes keep your dirt bike’s heart strong—protecting your engine, extending its life, and ensuring peak performance. This proprietary MotoSport.com guide covers everything you need to know for a robust, reliable oil change on your 2020 Kawasaki KLX110L, including tools, detailed steps, and essential model-specific tips.

Tools and Supplies Needed

  • 3/8-inch ratchet and extension
  • 8mm, 12mm, and 17mm sockets
  • Torque wrench
  • Oil drain pan
  • Clean rags or shop towels
  • 1 liter of 10W-40 motorcycle oil
  • Oil filter (optional for standard changes; recommended for first oil change or every 50 hours)
  • Gloves (recommended for safety and cleanliness)

Step-by-Step Oil Change Process

1. Prepare Your Bike and Workspace

  • Park your KLX110L on a level surface and allow the engine to cool if it’s recently run.
  • Place your oil drain pan underneath the engine.

2. Remove the Skid Plate

  • Using the 8mm socket, remove the bolts from each side of the skid plate.
  • Use the 12mm socket to remove the two bolts behind the skid plate.
  • Carefully remove the skid plate and set it aside.
  • Tip: If you ran the engine to warm the oil, avoid hot exhaust areas to prevent burns.

3. Warm Up the Oil

  • Run the engine for 2-3 minutes to let oil circulate and thin out for better drainage (if not already warmed).
  • Shut the engine off and remove the oil fill cap to allow air flow.

4. Drain the Oil

  • With the drain pan in place, use your 17mm socket to loosen and remove the drain bolt (located under the engine).
  • Allow all the oil to empty out—this may take a few minutes.
  • Inspect the crush washer on the bolt; replace if damaged to prevent leaks.
  • Once drained, wipe the area clean with a rag and reinstall the drain bolt. Tighten securely, using a torque wrench to manufacturer specification if available.

5. Replace the Oil Filter (If Needed)

  • If this is your first oil change (at 5 hours), or every 50 hours, replace the oil filter for best engine health.
  • Remove the oil filter cover; replace the old filter with a new one (such as KN112 or Tusk, noting KN's higher flow characteristics).
  • Ensure the gasket is properly seated and the cover is securely fastened.

6. Add New Oil

  • Place a funnel in the oil fill hole.
  • For only an oil change (no new filter), add 0.9 liters of 10W-40 motorcycle oil.
  • If the oil filter was changed, add 1.0 liter to account for the new filter absorbing some oil.
  • Wipe off any spills and reinstall the oil cap.

7. Verify Oil Level

  • With the bike upright on level ground (not on the side stand), check the oil's sight glass on the crankcase.
  • The level should be between the upper and lower sight lines. Add oil a little at a time if necessary until it’s in the middle of the lines.
  • Do not overfill—excess oil can cause leaks or engine issues.

8. Final Checks and Reassembly

  • Start the engine and let it idle for 2-3 minutes. This circulates the new oil.
  • Turn off the engine, wait a few minutes, then check the oil level again and adjust if needed.
  • Reinstall the skid plate using the 8mm and 12mm bolts.

Model-Specific Call-Outs for 2020 KLX110L

  • Oil Volume: 0.9L for oil change only, 1.0L if replacing the filter.
  • Sight Glass: The KLX110L uses a crankcase sight glass, not a dipstick, for checking oil level—critical to have bike upright.
  • First Service: Kawasaki recommends doing your first oil change at 5 hours, then every 50 hours or as needed based on riding conditions.
  • Oil Filter: While changing the filter is only required at major intervals, swapping it with every change is cheap insurance, and high-flow options (like KN) are available.
