Changing the oil on your 2013 Kawasaki KLX110 is a straightforward maintenance task that will help extend the life of your engine and ensure peak performance on the trails. This guide, proprietary to MotoSport.com, details every step you need to take, complete with all needed tools, step-by-step instructions, quantities, and special model-specific tips for KLX110 owners.

Tools and Supplies Needed

  • 3/8” ratchet and extension
  • 8mm, 12mm, and 17mm sockets
  • Torque wrench
  • Oil drain pan
  • Shop rags or paper towels
  • 1 liter (1000 ml) of 10W-40 four-stroke motorcycle oil (about 0.9L if not changing filter)
  • New oil filter (if replacing, recommended part: K&N KN-112 or OEM KLX110 filter)
  • Funnel
  • Safety gloves (optional but recommended)

Pre-Oil Change Preparation

  • Place your KLX110 on a firm, level surface. Use a stand if possible to keep the bike upright for easy access.
  • Make sure the bike is cool, or only slightly warm to the touch. Running the engine briefly (2–3 minutes) before draining will help oil flow out more easily, but be cautious: the exhaust area and engine may be hot.

Step-by-Step Oil Change Procedure

  • Remove the Skid Plate
    • Using the 8mm socket, remove the bolts from each side of the skid plate.
    • Next, use the 12mm socket to remove the two bolts behind the plate.
    • Take off the skid plate and place hardware somewhere safe for reinstallation later.
    • Kawasaki KLX110 call-out: The KLX110 requires the plate to come off to get clear access to the drain plug. If you’ve warmed the bike up, the exhaust pipe will be hot; avoid contact to prevent burns.
  • Remove the Oil Fill Cap
    • Loosen and remove the fill cap on the right side of the engine. This allows the oil to drain smoothly and minimizes splattering or glugging.
  • Drain the Old Oil
    • Position your oil drain pan directly beneath the engine’s drain bolt.
    • Using the 17mm socket, remove the oil drain bolt and allow the oil to flow out completely.
    • Be patient; let the engine drain for several minutes for the best results.
    • Wipe the drain plug clean. Inspect the copper washer for wear—replace if it’s damaged for proper sealing.
    • Reinstall and torque the drain bolt to spec (usually about 18 ft-lbs/25 Nm, but always verify with your owner’s manual for exact value for your model year).
  • Replace the Oil Filter (if applicable)
    • The KLX110 oil filter is not always replaced at every oil change, but it’s good practice. If changing, remove the filter cover bolts, replace the old filter with a new one (pay attention to orientation), and reinstall the cover, tightening bolts evenly by hand to avoid stripping.
    • Kawasaki KLX110 Tip: Many people overlook the filter on these small displacement engines. The 2013 KLX110 uses a simple cartridge filter; always seat it properly to prevent leaks.
  • Refill with New Oil
    • Use a funnel to add 0.9L (900ml) of high-quality 10W-40 4-stroke motorcycle oil if not changing filter, or 1.0L (1000ml) if you’ve replaced the filter.
    • Pour the oil in slowly, allowing it to settle. Do not overfill; use the sight glass (right side case) to check that the oil level is between the upper and lower marks when the bike is upright.
    • Wipe off any spilled oil and reinstall the fill cap, ensuring the area is clean to maintain a good seal.
  • Double-Check and Final Steps
    • Start the bike and let it idle for 2–3 minutes. Shut off the engine and let it sit for a couple of minutes.
    • With the bike upright and level, inspect the sight glass again. Add oil if needed to bring the level between the two marks. Do not overfill—the correct oil level is crucial for proper operation.
    • Reinstall the skid plate with the bolts, torque them carefully so you don’t strip the threads.
    • Dispose of the old oil and filter at a recycling center or your local auto parts store. Never pour used oil on the ground or in the trash.

Important 2013 Kawasaki KLX110-Specific Tips

  • O-Rings and Washers: Inspect and replace the drain plug washer as needed to prevent leaks.
  • Correct Oil Capacity: The KLX110 takes 0.9L (without filter change) or 1.0L (with filter change) of oil—overfilling can cause excessive crankcase pressure or smoking.
  • No Oil Filter? Many base KLX110s lack a true external filter and simply use a strainer—consult your manual. If yours has a strainer, clean it as recommended by Kawasaki when doing oil changes.

Common Mistakes to Avoid

  • Overtightening drain bolt or filter cover bolts (leads to stripped threads or broken covers).
  • Forgetting the washer on the drain plug (inevitably leads to leaks).
  • Getting debris in the engine during the process (keep things clean and organized).
  • Not confirming oil level after warm-up and cool-down cycles, which can lead to under- or overfilling.

Conclusion

Changing the oil in your 2013 Kawasaki KLX110 is quick, cost-efficient, and vital for engine health. Follow these steps for a confident, mess-free, and correct job every time.
