Changing the oil is essential for maintaining the life and performance of your 2013 Kawasaki KLX110L. This guide, brought to you by MotoSport.com, covers all tools required, detailed steps, and specific tips relevant to your model. Keeping your bike’s engine properly lubricated will prolong its life, maintain its performance, and help you catch other maintenance issues early.

Tools and Parts Needed

  • 3/8-inch ratchet and extension
  • 8mm, 12mm, and 17mm sockets
  • Torque wrench
  • Oil drain pan
  • New engine oil (generally 10w40; check your manual for specifications)
  • Replacement oil filter (optional, but recommended every other change)
  • Lint-free rags
  • Funnel
  • Gloves (for safety and cleanliness)

Step-by-Step Instructions

  • Warm Up the Engine
    Start the engine and let it idle for two to three minutes. This helps circulate and warm the oil, making it easier to drain.
    Tip: Do not let the bike get too hot, as you’ll be working near the engine soon.
  • Remove the Skid Plate
    Use the 8mm socket to loosen and remove the bolts on each side of the skid plate, and the 12mm socket for the two bolts behind the plate.
    Carefully set the plate aside.
    Caution: If the engine is hot, the exhaust pipe may be as well. Avoid touching it as you work.
  • Remove the Oil Fill Cap
    Twist and remove the oil fill cap to allow the oil to drain smoothly and completely. Place the cap somewhere clean.
  • Drain the Old Oil
    Position your oil drain pan beneath the engine.
    Using the 17mm socket, carefully loosen and remove the oil drain bolt at the bottom of the engine casing.
    Let the oil flow completely into your drain pan. Wait several minutes for thorough draining.
  • Optional: Replace the Oil Filter
    The KLX110L features an internal screen filter rather than a typical spin-on filter. If you wish to clean the filter screen, refer to your service manual for removal instructions.
    For best practice, clean or replace the screen every second oil change or if you suspect contamination.
  • Reinstall the Drain Bolt
    Wipe the bolt and the area around the drain hole with a lint-free rag.
    Thread the drain bolt by hand first to avoid cross-threading, then tighten it with a torque wrench to manufacturer specs (consult the owner’s manual or dealer for the proper torque for your model).
  • Add New Engine Oil
    Place a funnel in the oil fill opening. Add 0.9 to 1.0 liter of fresh 10w40 oil (amount varies if you change or clean the filter screen–without changing the oil filter, use 0.9L; with filter, use 1.0L).
    Recommendation: Add half the oil, wait a moment, then add the rest. This helps prevent overfilling.
  • Check Oil Level
    Set the bike on a level surface and ensure it’s upright (not on the side stand). Look at the oil sight glass or dipstick (depending on your model). The oil should be between the upper and lower marks.
    If necessary, slowly add oil in small amounts until the level is correct.
  • Reinstall the Oil Fill Cap
    Make sure the fill area is clean. Tighten the cap securely but carefully.
  • Run and Recheck
    Start the engine and allow it to idle for 1–2 minutes. Shut it off and allow the oil to settle for several minutes. Recheck your oil level–add a small amount more if needed. Inspect for leaks at the drain bolt and filter screen.
  • Reattach the Skid Plate
    Install the skid plate using the original bolts. Tighten them securely to manufacturer torque specifications.
  • Dispose of Used Oil
    Collect your used oil in a sealable container and take it to a certified recycling center or auto parts store that accepts used oil.

2013 Kawasaki KLX110L Call-Outs and Maintenance Tips

  • This model uses an internal oil strainer screen, not a traditional spin-on filter. Make sure to inspect and clean the screen regularly.
  • Be sure not to overfill: Overfilled oil can cause pressure issues and leaks. Always use the sight glass or dipstick for accuracy.
  • Use 10w40 4-stroke motorcycle oil: Avoid using automotive oils, as they may not protect the clutch and transmission properly.
  • Proper torque on drain bolts is crucial. Overtightening can strip threads in the engine case; undertightening can cause leaks. Double-check torque specs if unsure.
  • If the bike has recently been ridden hard or in mud/water, consider changing oil more frequently.
