Tools and Supplies Needed

  • 3/8" Ratchet
  • 8mm and 17mm sockets (the drain bolt is 17mm)
  • Torque wrench
  • Oil drain pan
  • Oil funnel
  • Shop rags or paper towels
  • Brake cleaner (optional, to clean up spilled oil)
  • Kawasaki OEM Oil Filter (Part #: 52010-1053) – optional but recommended every oil change
  • Kawasaki Drain Plug Gasket (Part #: 11061-0421) or new crush washer
  • 10W-40 motorcycle engine oil (at least 2 quarts; the capacity is 1.22 quarts for a full oil and filter change)

Specific Call-Out for the 2014 Kawasaki KLX140R 17/14

  • The oil capacity for a full oil change with filter is approximately 1.0–1.2 quarts (0.95–1.22 quarts); check your owner’s manual and do not overfill.
  • Always use motorcycle-specific oil to ensure compatibility with the wet clutch system.
  • Check your dipstick correctly: Screw it in all the way before checking the level, as the owner's manual diagram indicates.
  • No oil screen to clean; only the filter and oil need changing.
  • Reusable magnetic drain plugs are popular for this model to help capture minor ferrous debris.

Step-by-Step: How to Change the Oil

  • Warm up the engine: Start and let the engine idle for a couple of minutes. Warm oil drains better and suspends impurities so they come out with the old oil.
  • Remove the dipstick: With the engine off, remove the oil fill dipstick to allow the crankcase to vent. This allows the oil to drain fully

    .
  • Position the drain pan: Put the oil pan under the drain bolt on the lower left side of the crankcase.
  • Remove the drain bolt and washer: Use the 17mm socket and ratchet to remove the drain plug and crush washer. Allow the used oil to drain completely.
  • Remove the oil filter (if changing): Use the 8mm socket to remove the cover and replace the filter. Ensure the spring and o-ring go back in the correct locations. Lightly oil the new filter before installing.
  • Install a new crush washer: Always use a new drain plug gasket to prevent leaks.
  • Reinstall the drain bolt: Torque the bolt to spec (check your manual, usually 18 ft-lb (25 Nm)). Do not overtighten.
  • Fill with new oil: Insert the funnel and pour in about 1.0 quart of oil (for an oil change without filter), or up to 1.22 quarts if you changed the filter. You may need slightly less; it is best to start low and top off as needed

    .
  • Check the oil level: Insert the dipstick and screw it all the way in, then remove and check the level. The oil should reach the “full” mark, but not be above it

    .
  • Start and run the engine for 30–60 seconds: Shut off, wait a minute, and recheck the oil level with the dipstick screwed all the way in. Top off if needed.
  • Final checks: Check for leaks around the drain bolt and oil filter cover. Wipe off any spilled oil with shop rags and brake cleaner.
  • Dispose of old oil responsibly: Take your used oil and filter to a recycling center or suitable auto parts store.

Pro Tips for KLX140R Owners

  • Use a funnel to prevent spills on the cylinder head and exhaust.
  • Always have a spare crush washer and filter on hand; the washer may deform and cannot be reused safely.
  • Keep track of oil changes by marking the date and hours on a sticker or logbook attached to your bike or stored in your phone.
  • If you ride in harsh conditions (mud, dust, prolonged high rpm), change your oil more frequently than the manual recommends.
