Changing the oil in your 2017 Kawasaki KLX140R 17/14 is a vital maintenance task that ensures your dirt bike runs smoothly and reliably. This how-to guide covers every step you need to follow, the tools required, and specific call-outs for your KLX140R. These instructions are proprietary to MotoSport.com and tailored to your exact bike model and year.

Tools and Supplies Needed

  • Ratchet and extension
  • 8mm and 17mm sockets
  • Drain pan
  • Torque wrench
  • Oil filter (OEM recommended: Kawasaki #52010-1053 or equivalent)
  • Fresh motorcycle oil (10W-40 in 2 quarts, specifically formulated for wet clutches)
  • Crush washer (replace if damaged)
  • Gloves and rags (for safety and cleanup)
  • Funnel (to avoid spills)

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine:– Start the KLX140R and let it idle for 1-2 minutes. Warm oil flows more easily and removes more contaminants from the engine.
    Tip: Ensure the bike is in a well-ventilated area and not near flammable objects.
  2. Remove the Dipstick:– Turn off the engine. Locate and remove the oil dipstick from the right side of the engine. This step vents the crankcase and allows oil to drain faster.
  3. Drain the Old Oil:– Place your drain pan under the lower left side of the engine. Using a 17mm socket, remove the drain bolt and crush washer. Let the oil drain completely (several minutes). Inspect and, if necessary, replace the crush washer to prevent leaks.
  4. Remove and Replace the Oil Filter:– With the drain pan still in place, use an 8mm socket to remove the oil filter cover bolts. Carefully pull off the cover and remove the old oil filter. Wipe out any residue inside the cover and engine cavity. Insert the new oil filter—make sure it is installed in the correct orientation as specified in your owner's manual.
  5. Reinstall the Filter Cover and Drain Bolt:– Put the filter cover back on and torque the bolts evenly according to your manual's specifications. Reinstall the drain bolt with the new or cleaned crush washer. Torque the drain bolt to the manufacturer's spec to avoid overtightening.
  6. Add Fresh Oil:– Use a funnel to pour in fresh 10W-40 motorcycle oil. For the KLX140R, add approximately 1.2 US quarts (1.22 quarts for the L model, but always check your manual) as a good starting point.
  7. Check Oil Level Properly:–
    • Set the bike upright and level, not on its side stand.
    • Insert the dipstick and screw it all the way in (unlike some bikes, the KLX140R checks oil with the dipstick screwed in fully, per Kawasaki's specifications).
    • Remove the dipstick and check the oil level. It should be in the middle of the crosshatched area on the stick. Do not overfill.
    If the oil is low, add small amounts and recheck until the level is correct.
  8. Start and Re-Check:– Start the engine and let it idle for 30 seconds. Turn off, wait 1 minute for oil to settle, and check the oil again. Top off if needed until the level is within the proper range.
  9. Dispose of Old Oil and Filter Responsibly:– Take your used oil and filter to a recycling center or a MotoSport.com-approved drop-off location.
  10. Record Your Maintenance:– Note the date, mileage, and type of oil/filter used for your records and future service intervals.

Model-Specific Call-Outs for the 2017 Kawasaki KLX140R

  • Oil Capacity:– The standard KLX140R takes about 1.2 US quarts of oil with a filter change. Always check the dipstick after filling as small variations may occur.
  • Dipstick Check Method:– Kawasaki strongly specifies to check the oil with the dipstick screwed all the way in while the bike is upright and level. Many other motorcycles require checking with the dipstick resting, so don't skip this detail.
  • Drain Bolt Location:– The 17mm drain bolt is on the lower left of the crankcase. Carefully watch for hot oil and avoid damaging the threads by starting the bolt by hand when reinstalling.
  • Crush Washer:– Inspect and replace the crush washer every oil change to prevent leaks.
  • Oil Filter Orientation:– The filter must be installed in the proper direction; verify against the diagram in your owner's manual if unsure.
  • Torque Specs:– Overtightening bolts can strip threads in the case. Use a torque wrench set to factory specifications.

Why Change Your KLX140R's Oil Regularly?

  • Protects the engine from excessive wear and breakdown.
  • Removes contaminants which accumulate during riding.
  • Maintains smooth clutch performance (KLX140R uses a wet clutch system—use only motorcycle-specific oils designed for this purpose).

Final Thoughts

Regular oil changes are the most effective DIY maintenance to extend the life and enjoyment of your 2017 Kawasaki KLX140R. Follow these steps every 10-15 hours of riding or as recommended in your manual, and always use high-quality parts from trusted sources like MotoSport.com.
