An oil change is crucial for keeping your 2010 Kawasaki KLR650 running reliably, both on trails and city streets. Following these steps will help you do the job quickly and confidently. This guide provides model-specific tips, required tools, a detailed procedure, and proprietary insights for KLR650 owners, presented by MotoSport.com.

Tools and Materials Needed

  • 3/8-inch ratchet
  • 17mm or 18mm socket (check yours - some KLRs use 17mm, others 18mm, for the drain bolt)
  • 10mm socket (for oil filter cover bolts)
  • Torque wrench
  • Oil drain pan
  • Funnel
  • Gloves and rags
  • OEM or aftermarket oil filter
  • Kawasaki 10W-40 motorcycle oil (2.6 quarts for a full change)
  • New crush washer for drain bolt (recommended)
  • Screwdriver (to help gently pry off filter cap if needed)

2010 KLR650 Model-Specific Callouts

  • The oil drain plug is located under the engine. Double-check the bolt size as Kawasaki used both 17mm and 18mm heads depending on the production batch.
  • Gen 2 KLRs (2008-2018), including 2010, require the drain plug torqued to 21 ft-lbs.
  • Use a new crush washer with the drain plug at every change to avoid seepage.
  • When replacing the oil filter, ensure the stepped side or “bezel” faces inward, toward the engine.
  • Inspect oil filter O-ring for cracks or flattening; replace if needed.

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    • Start your KLR650 and let it run for 2-3 minutes. This warms the oil, making it drain completely and carry away more debris.
  2. Remove the Oil Fill Cap
    • Shut off the engine. Unscrew the oil fill cap located on the crankcase cover to relieve pressure and improve draining.
  3. Drain the Old Oil
    • Place an oil drain pan beneath the engine drain bolt.
    • Use a 17mm or 18mm socket and ratchet to remove the drain bolt.
      Tip: Hold the bolt in place until the last thread to minimize hand contact with hot oil.
    • Allow oil to drain completely—rock the bike side-to-side gently to evacuate all old oil.
    • Carefully remove the crush washer from the drain bolt. Replace with a new one if possible.
  4. Remove and Replace the Oil Filter
    • Locate the oil filter cover on the right side of the engine.
    • Use a 10mm socket to remove the two bolts securing the cover.
    • If stuck, gently pry the cover free using a screwdriver and rag to avoid marring the surface.
    • Inspect and clean the filter cover and O-ring. Replace the O-ring if cracked or squished.
    • Remove the old oil filter and the small metal bypass valve—note orientation (the stepped side goes toward the engine).
    • Lightly oil the new filter’s seals. Insert the bypass valve (if present) and new filter, correct side in.
    • Line up the filter cap (arrow up, tab at lower right), and hand-thread bolts to avoid stripping. Snug with ratchet, then torque to 8 ft-lbs if desired.
  5. Reinstall Drain Plug
    • After all oil drains out, clean the sealing surface. Install the drain bolt with new crush washer and torque to 21 ft-lbs (28 Nm) for 2010 KLR650s.
  6. Refill With New Oil
    • Place a funnel in the oil fill port. Pour in 2.6 quarts (2.5 liters) of 10W-40 motorcycle-specific oil.
    • Reinstall the fill cap, ensuring the O-ring is secure.
  7. Check Oil Level and Inspect for Leaks
    • Start the engine and let it run for 30-60 seconds. Turn it off and allow the bike to sit for a minute.
    • With the bike upright (not on the side stand), verify the oil level in the sight glass on the right side.
    • Add oil in small amounts if needed–do not overfill.
    • Check around the filter cover and drain plug for leaks. Retorque as necessary.
