Regular oil changes are essential to keep your 2019 Kawasaki KLX110L running at its best. Performing this maintenance yourself not only saves money but also helps you become more familiar with your dirt bike. Here's a comprehensive, step-by-step guide—proudly brought to you by MotoSport.com.

Tools and Supplies Needed

  • 3/8-inch ratchet and extension
  • 8mm, 12mm, and 17mm sockets
  • Torque wrench
  • Oil drain pan
  • Clean rags
  • New engine oil: 10w-40 motorcycle oil (approx. 0.9 liters if not changing the filter, 1 liter if changing)
  • New oil filter (optional for this model; refer to manufacturer's guidelines)

Preparation

  • Warm up the engine by running it for a few minutes. This helps the oil drain completely.
  • Make sure the bike is on a level surface, using a stand if available.
  • Have all your tools and new oil ready to go.

Step-by-Step Oil Change

  • Remove the Skid Plate:
    • Use your 8mm socket to remove the bolts on each side of the skid plate.
    • Remove the two 12mm bolts located behind the skid plate.
    • Take off the skid plate and set it aside.
      Note: If you warmed up the bike before this step, the exhaust will be hot. Use caution to avoid burns.

  • Remove the Oil Fill Cap:
    • Unscrew the oil fill cap located on the side of the engine to allow oil to drain freely.

  • Drain the Old Oil:
    • Position the oil drain pan under the drain bolt (bottom of engine).
    • Use your 17mm socket to unscrew and remove the drain bolt.
    • Allow all the oil to drain—this may take a few minutes.

    • Inspect the drain bolt and washer; replace if damaged.
  • Replace Oil Filter (Optional):
    • The KLX110L does not have a traditional spin-on oil filter but has a screen that can be accessed and cleaned if needed. Refer to your owner's manual for details. Many owners choose to clean or replace this every other oil change.

  • Reinstall the Drain Bolt:
    • When the oil has finished draining, clean the drain bolt and reinstall it with the proper torque—avoid over-tightening as the case material is soft.

  • Refill with Fresh Oil:
    • Place a funnel in the oil fill hole.
    • Pour in 0.9 liters (just under 1 quart) of 10W-40 motorcycle oil if not replacing the filter. If you have replaced or cleaned the screen filter, use the full 1 liter.

    • Remove the funnel, check for spills, and wipe the area clean.
    • Install the oil fill cap securely.
  • Run and Check the Engine:
    • Start the engine and let it idle for a few minutes to circulate new oil.
    • Shut off the engine and wait a few minutes for oil to settle.
    • Check the oil level in the sight glass on the side of the engine case. Oil should be between the upper and lower marks. Add oil if needed.

  • Reinstall the Skid Plate:
    • Reattach the skid plate using the 8mm and 12mm bolts.
    • Tighten bolts securely but avoid stripping the threads.

Model-Specific Call-Outs for 2019 Kawasaki KLX110L

  • The KLX110L uses a simple oil screen instead of a disposable filter. Cleaning this screen during your first few oil changes is highly recommended for optimal performance.

  • Be careful when reinstalling drain bolts and skid plate bolts. The engine case is aluminum and threads are easy to strip—use a torque wrench if possible.
  • Engine oil capacity is approximately 0.9 liters if not removing the filter; do not overfill as too much oil can reduce engine performance.

  • If your bike's sight glass is cloudy or scratched, replace it to ensure easy oil checks in the future.

Disposal

  • Dispose of old oil at an approved recycling center. Do not throw oil in the trash or pour on the ground—take pride in maintaining your bike and the environment.
