If you ride a 2015 Kawasaki KLX110L, regular oil changes are vital to keep your dirt bike running strong, ensure engine longevity, and stay ahead of costly repairs. This step-by-step guide, proprietary to MotoSport.com, covers everything you need—from required tools, recommended oil, to specific tips for your KLX110L model.

Tools & Supplies Needed

  • 3/8" ratchet and extension
  • 8mm, 12mm, and 17mm sockets
  • Torque wrench (for precision when reinstalling bolts)
  • Oil drain pan
  • Shop rags or paper towels
  • Funnel
  • Oil–10W-40 motorcycle-specific engine oil (approx. 1 liter)
  • New oil filter (optional but recommended, especially if it's been several cycles since last replaced)
  • New crush washer for drain bolt (optional, prevents leaks)
  • Gloves (to stay clean)

Important Model-Specific Notes for the 2015 KLX110L

  • Always let the engine idle for several minutes before draining oil; this thins oil for a more complete drain and suspends contaminants.
  • The KLX110L uses a 17mm drain bolt located at the bottom of the engine.
  • The oil sight glass on the right side of the engine allows easy checking of the oil level after refilling.
  • Oil capacity with a filter change is about 1.0 – 1.1 liters—always check your owner’s manual and use the sight glass to confirm.
  • Be careful if the engine is hot: The exhaust header runs close to the skid plate; wear gloves to prevent burns.

Step-by-Step Oil Change Instructions

  • Prepare Your Work Area. Park the bike on a stable, level surface. Put down cardboard or newspaper to catch any spills.
  • Remove the Skid Plate.
    – Use an 8mm socket to remove the bolts on each side of the skid plate.
    – Next, remove the two 12mm bolts located behind the skid plate.
    – Remove the skid plate and set it aside.
    Tip: If your engine was running, the exhaust may be very hot. Handle with care.
  • Warm Up Your Engine (if not done already).
    – Start and idle the bike for 2-3 minutes, then turn it off. This will suspend impurities in the oil for a cleaner drain.
  • Remove the Oil Fill Cap.
    – Unscrew the oil fill cap on the right side of the engine to help oil drain faster and more completely.
  • Drain the Old Oil.
    – Place the drain pan directly under the oil drain bolt (17mm).
    – Use the 17mm socket and ratchet to remove the bolt while supporting it to avoid dropping it into the drain pan.
    – Allow all the oil to completely drain out; this may take several minutes.
    – Inspect the old oil for metal shavings or debris, which can indicate engine wear.
  • Replace the Oil Filter (if applicable).
    – Most KLX110L models use an internal screen instead of a traditional spin-on filter; reference your service manual.
    – If you are replacing the filter or cleaning the oil screen, follow the specs and torque values found in your owner’s manual.
  • Install the Drain Bolt.
    – Clean the bolt and replace the crush washer if it shows signs of wear.
    – Reinstall the bolt by hand to prevent cross-threading, then torque it to spec (consult your owner’s manual for the correct value).
  • Add New Oil.
    – Place the funnel in the oil fill port.
    – Pour in just under 1 liter (about 0.95-1.0L if you did not replace the filter; about 1.1L with a new filter).
    – Let the oil settle, then check the level via the sight glass with the bike upright and off the stand.
  • Double-Check Oil Level.
    – If needed, add oil to get the level between the upper and lower marks of the sight glass.
    – Do not overfill—oil expands with engine heat.
  • Start the Engine and Circulate Oil.
    – Reinstall the oil cap.
    – Start and idle the engine for about 3 minutes, then shut it off.
    – Wait a couple of minutes for the oil to settle, then check the sight glass again and top off as necessary.
  • Reinstall the Skid Plate.
    – Bolt the skid plate back in place, tightening the bolts evenly.
  • Dispose of Used Oil Responsibly.
    – Pour the old oil into a sealable container and take it to a recycling or auto parts center.

Pro Tips for 2015 Kawasaki KLX110L Owners

  • Check the oil regularly—your KLX110L uses a small volume and is unforgiving of neglect.
  • Always use motorcycle-specific oil with the correct rating (such as 10W-40 JASO MA/MA2).
  • Frequent hard riding or dusty trail conditions may require more frequent oil changes (every 10–15 hours of riding).
  • For best results, always check drain bolt torque and oil specification in your owner’s manual before starting.

Maintaining your 2015 Kawasaki KLX110L with regular oil changes is the best way to ensure reliable, fun-filled riding seasons. Performing this task yourself with genuine quality parts from MotoSport.com saves money and deepens your connection to your bike.
