2013 KLR650-Specific Call-Outs

  • The oil capacity is 2.6 quarts (include oil for the new filter).
  • Reuse the drain plug crush washer only if it's in excellent condition. Replace if in doubt to prevent leaks.
  • Be mindful of the oil filter cover tab orientation and the internal by-pass valve, both unique to the KLR650 engine family.
  • Inspect the O-ring on the filter cover and replace if it’s cracked, nicked, or flattened.
  • Keep track of the small internal metal baffle behind the oil filter, as it must go back in the correct orientation.

Step-by-Step Oil Change Instructions

  • Start and Warm Up: Run the engine for 2-3 minutes to warm up the oil. This helps it drain faster and removes more contaminants. Shut the engine off and set the bike securely on its side stand or a center stand if equipped.
  • Remove Oil Fill Cap: Open the oil filler cap on the right side engine case. This prevents a vacuum and aids draining.
  • Position Oil Catch Pan: Locate the oil drain bolt (bottom of the engine, left side). Slide the oil pan underneath to catch all old oil.
  • Drain the Oil: Using your 17mm or 18mm socket and ratchet, carefully remove the oil drain bolt. Hold the bolt firmly until the last threads to avoid dropping it into the pan. Let all oil drain out, and if needed, gently rock the bike upright and back several times to get the last drops out. Watch for and save the crush washer.
  • Remove the Oil Filter: Locate the oil filter cover on the lower right side of the engine. Remove its two bolts carefully with a 10mm socket, being mindful of the orientation tab. If the cover is stuck, use a small screwdriver to gently break the seal—avoid damaging the mating surfaces. Place the cover aside and remove the old filter and metal baffle (note orientation).
  • Inspect and Clean:
    • Wipe any oil and debris from the filter cover, seating surface, and inside the filter housing.
    • Inspect the O-ring for wear. Replace if needed. Lightly oil a good O-ring to aid sealing.
    • Clean and inspect the drain bolt and threads; replace the crush washer if worn.
  • Install New Filter & Cover:
    • Lightly oil the new filter’s sealing edge and the O-ring you inspected. Insert the metal baffle back into place (beveled or stepped edge towards the engine) and install the new filter.
    • Position the oil filter cover with the arrow facing up and the orientation tab aligned correctly. Start both bolts by hand to prevent cross-threading and then evenly tighten with your ratchet. Avoid overtightening.
  • Install Drain Bolt: With a new or inspected crush washer, reinstall the drain plug. Start threading by hand, then snug with your socket and torque to Kawasaki’s specifications (typically around 21 lb-ft, but check your service manual for 2013-specific torque).
  • Add Fresh Oil: Place a clean funnel in the fill hole. Pour in 2.6 quarts of high-quality 10W-40 motorcycle oil. Replace the filler cap (ensure O-ring is seated and clean) and tighten securely by hand.
  • Check for Leaks & Oil Level:
    • Start the engine and let it idle for about 1-2 minutes. Inspect the drain bolt and filter cover for leaks.
    • Turn the bike off, let it sit a moment, and check the oil level in the sight glass on the right crankcase cover. Add oil as needed to bring the level to the upper mark, but do not overfill.
  • Clean Up: Wipe off any drips, double check all bolts and the filler cap are secure, and properly dispose of the old oil and filter at a recycling center.

Tips and Reminders

  • Change your oil every 2,000-3,000 miles or sooner when riding in dirty or hot conditions.
  • An oil filter should always be changed with your oil in the KLR650.
  • If you drop anything in the oil pan, retrieve it before refilling the bike.
  • Always inspect for leaks after your first short ride post-oil change.

Your 2013 Kawasaki KLR650 is ready for the long haul. Regular oil and filter changes are the key to legendary reliability – fast, simple, and friendly for DIYers of any experience level.
