Changing the oil on your 2008 Kawasaki KLX110 is an essential part of routine maintenance that prolongs engine life and ensures smooth riding. This guide from MotoSport.com provides step-by-step instructions, including the tools you'll need and key model-specific notes for your dirt bike.

Tools and Supplies Needed

  • 3/8-inch ratchet and extension
  • 8mm, 12mm, and 17mm sockets
  • Torque wrench
  • Oil drain pan
  • One liter of 10W-40 motorcycle oil (full change) or 0.9 liters if skipping filter
  • Replacement oil filter (if changing filter)
  • Shop rags for cleanup
  • Latex or nitrile gloves (optional, for clean hands)

Step-by-Step Oil Change Instructions

  • Warm Up the Engine –
    Start your KLX110 and let it idle for 2-3 minutes. This warms up the oil, allowing it to drain more completely. Do not touch the exhaust or engine after running—they will be hot.
  • Remove the Skid Plate –
    Use the 8mm socket to remove bolts on each side of the skid plate, then use the 12mm socket for the bolts behind the skid plate. Carefully remove the skid plate and set it aside.
    Tip: Removing the skid plate gives better access to the drain bolt and avoids getting oil on the plate.
  • Remove the Oil Fill Cap –
    Unscrew the oil fill cap to allow for faster, smoother oil draining by breaking the vacuum inside the engine.
  • Drain the Oil –
    Place the oil drain pan beneath the engine's drain bolt. Use the 17mm socket and ratchet to remove the drain bolt and let the old oil flow out.
    Wait several minutes for the oil to fully drain.
    Inspect the old oil for metal shavings or debris as a check on engine condition.
  • Change the Oil Filter (If Applicable) –
    If you wish to replace the filter, locate and remove the oil filter. Check your service manual for the exact location on the KLX110 and install a new compatible filter.
    Lubricate the new filter's O-ring with a little fresh oil before installing.
  • Reinstall Drain Bolt –
    Clean the sealing surfaces on the engine and the drain bolt. Torque the drain plug to the manufacturer's specification to avoid stripping threads.
  • Refit the Skid Plate –
    Put the skid plate back in position and secure it with the bolts you removed earlier.
  • Refill with New Oil –
    Insert a funnel in the oil fill hole. Pour in up to one liter of 10W-40 motorcycle oil if you changed the filter, or 0.9 liters if you did not.
    Remove funnel and replace the oil fill cap.
  • Check Oil Level and Final Inspection –
    Start the engine and let it run for about three minutes. Stop the engine and let the bike sit for another three minutes to allow the oil to settle.
    Ensure the bike is upright (not leaning on the kickstand). Check that the oil level falls between the upper and lower marks in the sight glass. Add or remove oil as needed to reach the proper level.
  • Dispose of Used Oil and Filter Properly –
    Take the old oil and filter to a certified recycling center or auto parts store.

  • Use only high-quality 10W-40 motorcycle oil that meets Kawasaki's recommended specifications for best performance.
  • Always torque the drain bolt properly—over-tightening may strip threads in the crankcase, leading to costly repairs.
