Changing the oil in your 2010 Kawasaki KLX110 is essential for keeping your engine running smoothly and protecting its moving parts. Regular oil changes prolong the life of your dirt bike and enhance performance. This step-by-step guide, proprietary to MotoSport.com, outlines the required tools, detailed procedures, and critical model-specific notes every KLX110 owner should know.

Tools & Supplies Needed

  • 8mm socket
  • 12mm socket
  • 17mm socket
  • 3/8-inch ratchet and extension
  • Torque wrench
  • Oil drain pan
  • Clean rags or paper towels
  • New engine oil (1.1 quart of 10W-40 motorcycle oil recommended)
  • (Optional) New oil filter (if equipped/applicable)

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    • Start the engine and let it idle for about 3-5 minutes. This helps the oil flow more freely, ensuring a thorough drain.
    • Model note: Be cautious—after warming the engine, the exhaust and other parts will be hot to the touch. Allow a minute or two for slight cooling before proceeding.
  2. 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.
    • Take off the skid plate and set it aside.
  3. Prepare to Drain the Oil
    • Place your oil drain pan beneath the engine, directly under the drain bolt.
    • Using a 17mm socket, remove the oil drain bolt.
    • Allow all the old oil to drain completely into the pan.
  4. Clean Oil Fill Area
    • Before removing the oil fill cap, wipe the area clean with a rag to prevent any dirt or dust from entering the engine.
    • Remove the oil fill cap.
  5. Inspect and Replace the Drain Bolt
    • Once the oil is fully drained, inspect the drain bolt and washer for signs of wear or damage.
    • Replace the washer if necessary and reinstall the drain bolt. Tighten it securely with the 17mm socket—do not over-tighten to avoid stripping threads.
  6. Change or Clean the Oil Filter (if applicable)
    • The 2010 KLX110 typically does not have a replaceable oil filter, but some riders choose to clean any in-line screens. Consult your owner’s manual for model-specific filter information. If equipped, replace the oil filter at this step.
  7. Add New Oil
    • With the bike upright and on level ground, use a funnel to add 1.1 quarts (about 1 liter) of 10W-40 motorcycle oil through the oil fill cap.
  8. Check Oil Level
    • Reinstall the fill cap and start the engine. Let it run for 2-3 minutes.
    • Turn off the engine and let the oil settle for a few minutes.
    • Place the bike upright (off the kickstand) and check the oil level through the sight glass. The oil should be between the upper and lower marks.
    • If needed, add a small amount of oil to reach the correct level.
  9. Reinstall the Skid Plate
    • Replace the skid plate and secure it using the original 8mm and 12mm bolts.
    • Tighten all bolts to factory specifications.
  10. Clean Up
    • Wipe off any spilled oil, properly dispose of old oil and filter, and check for any leaks.

Model-Specific Call-Outs: 2010 Kawasaki KLX110 Owners

  • Oil Amount: For a full oil change, including draining the crankcase, use 1.1 quarts (or about 1 liter) of 10W-40 oil.
  • Filter: The standard 2010 KLX110 does not have a cartridge-style oil filter but check for an inline oil screen and clean if accessible.
  • Drain Bolt Location: The drain bolt is underneath the engine, and access requires removal of the skid plate.
  • Inspection Window: Use the round sight glass on the engine case to check your oil level. Be sure the bike is vertical–not on the kickstand–when checking.
  • Torque Specs: Avoid over-tightening bolts, especially the drain bolt. If you have a torque wrench, tighten to manufacturer specs, typically around 18 ft-lbs (24 Nm), but confirm with your manual.

Final Reminders

  • Always change your oil after break-in, then roughly every 10 hours of riding or sooner if you ride in harsh conditions.
  • Check your owner’s manual for oil and maintenance intervals specific to your riding style and environment.
  • Properly dispose of used oil and filters in compliance with local regulations.
