2010 KLX110L-Specific Call-Outs

  • The KLX110L skid plate is secured with both 8mm and 12mm bolts.
  • Let the engine warm up for approximately 5 minutes to help the oil flow out easily, but allow it to cool slightly before handling hot parts.
  • No separate oil filter (uses oil spinner instead), but it's wise to clean the oil fill area every change.
  • Oil quantity: 1.1 quart (about 1 liter).

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    • Start your KLX110L and let it idle for 5 minutes. This thins the oil so it flows easily and carries more particles out when drained.
    • Caution: Let the engine cool briefly to avoid burns from hot parts.
  2. Remove the Skid Plate
    • Locate and remove the 8mm bolts on each side of the skid plate.
    • Remove the two 12mm bolts behind the skid plate.
    • Remove the skid plate for easy access to the drain bolt and avoid mess.
  3. Loosen the Oil Fill Cap
    • Unscrew the oil fill cap at the top of the engine on the right side. This allows air to enter and helps the oil drain more thoroughly.
    • Wipe around the fill cap first to keep dirt from falling into the engine.
  4. Drain the Oil
    • Place your oil drain pan under the engine's drain bolt.
    • Use a 17mm socket to remove the drain bolt and washer from the engine's underside. Allow oil to drain completely.
    • If desired, check and clean the mesh screen inside the drain plug for debris.
  5. Inspect and Reinstall the Drain Plug
    • Inspect the crush washer for wear—replace if deformed to prevent leaks.
    • Clean the drain plug and re-install it by hand, then snug it up with your 17mm socket.
    • Torque to factory spec (typically around 18 ft-lbs; check your manual).
  6. Fill with Fresh Oil
    • Using a funnel, pour in 1.1 quarts (1,040mL) of 10W-40 motorcycle oil through the oil fill hole.
    • Check for leaks from the drain bolt and ensure oil level does not exceed the upper sight glass mark.
  7. Warm Up and Check Oil Level
    • Reinstall the oil fill cap, start the bike, and let it run for about 3 minutes.
    • Turn the engine off and wait a couple of minutes to let the oil settle in the sight glass.
    • With the bike perfectly vertical on a level surface, check the sight glass. Oil should be between the upper and lower marks. Add oil if needed.
  8. Reinstall the Skid Plate
    • Reattach the skid plate with the cleaned 8mm and 12mm bolts.
    • Tighten to secure—avoid overtightening to prevent stripping the threads.

Pro Tips for the 2010 KLX110L

  • Always keep your work area clean to avoid introducing dirt into the engine—this is crucial on dirt bikes.
  • If you're doing frequent changes due to racing or hard riding, consider using a premium synthetic oil.
  • After the first post-change ride, check for leaks and top off oil if needed.
  • The 2010 KLX110L does not use a conventional oil filter—for deep cleaning, periodically service the oil spinner (internal part, not part of routine oil change).
