Changing the oil in your 2012 Kawasaki KLX110L is a vital part of dirt bike maintenance, ensuring engine longevity and optimal performance. This comprehensive guide, proprietary to MotoSport.com, will walk you through all steps, highlight required tools, and point out KLX110L-specific notes every owner should know.

Tools & Parts Needed

  • 3/8” ratchet and extension
  • 8mm, 12mm, and 17mm sockets
  • Torque wrench
  • Oil drain pan
  • Clean rags or shop towels
  • New engine oil (10W-40, 0.9 to 1.0 liters for standard change)
  • New crush washer for drain bolt (recommended)
  • Funnel

Pre-Oil Change Preparation

  • Warm up the Engine: Start your KLX110L and let it idle for 2-3 minutes. This thins the old oil and helps it drain faster and more thoroughly.
  • Ensure the bike is on a level surface and secure it with a bike stand for easy access.

Step-by-Step Oil Change Process

  • Remove the Skid Plate:
    • Use your 8mm socket to remove the bolts on each side of the skid plate.
    • Switch to your 12mm socket for the two bolts located behind the skid plate.
    • Carefully remove the skid plate and set it aside.
    • KLX110L Note: The exhaust pipe may be hot if the engine was just run—be careful not to burn yourself when reaching near the engine area.
  • Remove the Oil Fill Cap:
    • Unscrew the oil fill cap on the right side of the engine to allow oil to drain freely.
  • Drain the Oil:
    • Position your oil drain pan directly beneath the oil drain bolt underneath the engine.
    • Use your 17mm socket to loosen and remove the oil drain bolt.
    • Allow all old oil to fully drain. This may take several minutes.
    • Inspect the old drain bolt and replace the crush washer if it appears damaged.
  • Reinstall the Drain Bolt:
    • Wipe the drain bolt threads and the area around the drain port to ensure a clean sealing surface.
    • Re-install the drain bolt (with new crush washer); tighten to the manufacturer’s specification with a torque wrench (consult manual for exact spec).
  • Refill with New Oil:
    • Place a funnel in the oil fill port.
    • Pour in 0.9 liters (just under 1 US quart) of 10W-40 motorcycle oil if you’re not replacing the oil filter. If you are, use 1.0 liter.
    • Replace the oil fill cap and tighten securely.
  • Check Oil Level:
    • Start the engine and let it idle for 2-3 minutes to circulate the new oil throughout the engine.
    • Wait another 2-3 minutes after shutting off the engine for the oil to settle in the pan.
    • Keep the bike level and check the oil level through the sight glass. The oil should be visible between the upper and lower marks on the glass.
    • If the oil is below the center line, add small amounts as needed and recheck until at proper level.
  • Reinstall the Skid Plate:
    • Replace the skid plate and fasten using the original bolts (8mm and 12mm). Do not overtighten.
  • Dispose of Old Oil Properly:
    • Take your used oil to a designated oil recycling facility or local auto parts store that offers oil recycling.

Model-Specific Details for the 2012 KLX110L

  • The KLX110L features a sight glass for quick oil level checks—always verify level after each change.
  • Always use the correct torque for the drain bolt (check your owner’s manual; typically around 18 ft-lbs but confirm for your model).
  • The oil filter is not a typical cartridge filter but rather a centrifugal type inside the clutch cover, not usually replaced on standard oil changes. Only service during larger maintenance intervals.
  • Using quality, motorcycle-specific 10W-40 oil is recommended to protect the KLX110L’s wet clutch and engine internals.
  • The recommended oil volume is 0.9 liters without filter change and 1.0 liter with filter change.

Pro Tips

  • Track your oil changes with a service log or sticker on the frame.
  • Inspect the old oil for metallic particles, which could indicate abnormal engine wear.
  • Wipe up any spills immediately to prevent buildup of grime.
  • If you encounter stuck fasteners, use penetrating oil and patience; avoid over-torquing bolts to prevent stripped threads.
