This guide, proprietary to MotoSport.com, will walk you through the tools you need, each step of the process, and special details specific to the 2011 KLR650.

Tools and Supplies Needed

  • 3/8” ratchet
  • 18mm socket
  • 10mm socket
  • Torque wrench
  • Drain pan (for old oil)
  • New oil filter (OEM or aftermarket recommended)
  • Kawasaki 10W40 oil (2.6 quarts for refill)
  • Funnel
  • Paper towels or rags
  • Screwdriver (to help gently pry the filter cover, if needed)
  • Latex or nitrile gloves (optional, for cleanliness)

Steps to Change Oil on a 2011 Kawasaki KLR650

  • Warm the Engine:– Start your KLR650 and let it idle for a few minutes. This helps circulate the oil, making it flow more freely when draining.
    Tip: Only warm the engine, don’t overheat. Warm oil drains faster and more thoroughly.
  • Remove the Oil Fill Cap:– Locate the oil fill cap on the right side crankcase cover and loosen it. This step allows air to flow and enables quicker draining.
    Call-out: The fill cap is accessible on the right side; removing it early speeds up the draining process.
  • Locate the Drain Bolt:– The drain bolt sits at the bottom of the engine, roughly centered underneath the bike. Place your drain pan directly underneath.
    Call-out: Don’t lose the drain bolt’s crush washer when removing the bolt, as this can cause leaks if not re-installed properly.
  • Remove the Drain Bolt:– Use an 18mm socket and ratchet to loosen and remove the drain bolt. Allow all the old oil to drain fully into your oil pan.
    Tip: Rock the bike gently side to side to ensure all oil is expelled.
  • Remove the Oil Filter Cover:– Locate the oil filter cover on the right side of the engine. Use a 10mm socket to remove the two bolts securing the cover.
    Call-out: Be careful with the small tab on the filter cover. Gently pry with a screwdriver if needed, placing a paper towel to avoid scratches.
  • Replace the Oil Filter:– Remove and inspect the old oil filter. Take out the metal bypass valve (bezel side goes in first on reassembly). Clean the filter cavity and install the new oil filter, lightly oiling its rubber o-rings for a good seal.
    Tip: Make sure to position the filter with the correct end (bezel side) toward the engine.
  • Reinstall the Oil Filter Cover:– Ensure the cover o-ring is in good shape and seated properly. Add a bit of oil to the o-ring, reinstall the cover with the arrow facing up, and torque the bolts by hand to prevent cross-threading, then tighten with your torque wrench.
  • Reinstall the Drain Bolt:– Inspect the crush washer for wear and replace if necessary. Reinstall the drain bolt and torque it to manufacturer specs (consult your owner’s manual for exact torque value).
  • Add New Oil:– Using a funnel, pour in 2.6 quarts of Kawasaki 10W40 oil through the fill port. Reinstall the oil fill cap.
  • Run the Engine and Check for Leaks:– Start the bike and let it idle for a few minutes. Turn the bike off, then check around the drain plug and oil filter cover for leaks. Top off the oil if needed after the bike sits for a minute and the oil settles.
  • Dispose of Used Oil and Filter:– Properly recycle your used engine oil and filter according to local regulations.

Special Notes for the 2011 KLR650

  • Oil Capacity:– The 2011 KLR650 takes 2.6 quarts of oil, including oil filter change. Using more or less can affect engine performance or cause leaks.
  • Drain Bolt Care:– Double-check the drain bolt’s crush washer for wear; a faulty washer is a common source of leaks on this model.
  • Oil Filter Cover Orientation:– Pay attention to the arrow marking and the lower right tab on the filter cover; incorrect installation may cause leaks.
  • Bypass Valve Placement:– Ensure the metal bypass valve (bezel side) is installed into the engine case before the filter for proper oil flow.
  • Thread Care:– Always start bolts and screws by hand. The aluminum threads on the KLR’s engine cases can strip easily if cross-threaded or overtightened.

Conclusion

Changing the oil in your 2011 Kawasaki KLR650 is straightforward with the right tools and attention to detail. Keeping up on oil changes ensures your engine runs smoothly, providing reliable performance on and off the road. For best results, always use high-quality oil and OEM replacement filters.
