Tools and Supplies Needed

  • Ratchet and extension
  • 8mm and 17mm sockets
  • Drain pan
  • Torque wrench
  • Replacement oil filter (OEM, part #52010-1053 or equivalent)
  • 10W-40 motorcycle oil (1.22 US quarts, but have 2 quarts on hand)
  • New drain plug crush washer (recommended for every change)
  • Funnel (optional, but reduces mess)
  • Clean rags or shop towels
  • Gloves (optional, but helps keep your hands clean)

Before You Begin: Model-Specific Callouts

  • The KLX140R L 19/16 uses a simple wet-sump oil system. The OEM oil filter is behind an easily accessible cover held by 8mm bolts.
  • Oil capacity is 1.22 quarts – do not overfill. Always verify with the dipstick, following the procedure below.
  • Letting the engine idle a few minutes before draining is essential to help old oil flow out completely.
  • After running, exhaust and engine parts will be hot. Avoid burns by letting it cool briefly, but drain while oil is warm.

Step-by-Step Oil Change Procedure

1. Warm Up Your Bike

  • Start the KLX140R L and let it idle for about one minute. Warm oil drains faster and more thoroughly.
    Be careful: Exhaust and engine parts can get hot quickly.

2. Remove the Dipstick

  • Turn off the engine and position the bike on a stand or level ground.
  • Unscrew and remove the oil dipstick from the crankcase. This allows the crankcase to vent and helps oil drain more completely.

3. Drain the Old Oil

  • Place your drain pan under the engine. Locate the 17mm drain bolt on the lower left side of the crankcase.
  • Using your ratchet and 17mm socket, loosen and remove the drain bolt and the crush washer.
    Be careful: Oil may flow out quickly and can be hot.
  • Allow all the oil to drain. This may take several minutes.

4. Replace the Oil Filter

  • Use your 8mm socket and ratchet to remove the bolts from the oil filter cover.
  • Gently pull off the cover. You may need to gently pry if it sticks – do not force it.
  • Remove the old oil filter, noting its orientation and the position of any spring or washers behind it.
  • Clean the filter cavity and mating surfaces with a clean rag, removing any sludge or debris.
  • Install the new oil filter in the same orientation. Make sure any springs or washers are re-installed precisely as they came out.
  • Reinstall the cover and tighten the 8mm bolts evenly by hand, then finish with a torque wrench to factory specifications (do not overtighten).

5. Reinstall the Drain Bolt

  • Once oil has completely drained, replace the crush washer with a new one (highly recommended to prevent leaks).
  • Reinstall the drain bolt and tighten with your 17mm socket and torque wrench to spec (consult your owner’s manual; typically 15–22 ft-lb for small Kawasaki engines).

6. Add Fresh Oil

  • Using a funnel, add 1.22 quarts of 10W-40 motorcycle oil suitable for wet clutches (avoid automotive oils).
  • Install the dipstick but do not screw it in. Remove it and check the oil level. Top off if necessary, always filling to just below the “F” (full) mark while the bike is upright.

7. Check for Leaks and Final Inspection

  • Start the engine and let it idle for one minute. Inspect both the drain bolt and oil filter area for any drips or leaks.
  • Turn off the engine and wait 2–3 minutes for the oil to settle.
  • Remove the dipstick, wipe it, reinsert (without screwing in), and check the oil level again. Top off if necessary.

8. Clean Up & Dispose of Old Oil Properly

  • Always dispose of used oil and the old filter at a recycling facility or authorized auto parts store. Never pour oil onto the ground or into drains.
  • Wipe down any spilled oil, replace tools, and enjoy your freshly serviced KLX140R L.

Tips, Tricks & Model-Specific Advice

  • KLX140R L 19/16 models (including 2013) feature side access to the oil filter for convenience. No bodywork removal is needed.
  • Keep spare crush washers on hand, as reusing old ones is a common source of leaks.
  • If you're new to oil changes, double-check all torque settings and never force fasteners or skip the correct oil specification.
  • The KLX’s air-cooled engine benefits from frequent oil changes—consider changing at shorter intervals if you ride in dusty or hot conditions.

Why Change KLX140R L Oil Yourself?

  • Save money on shop labor.
  • Build confidence and knowledge about your machine.
  • Ensure only the best parts and oil are used.

By following this guide, you’ll be set to keep your 2013 Kawasaki KLX140R L 19/16 in top running shape, enjoying more worry-free rides for years to come.
