Step-by-Step Instructions

  1. Warm Up the Engine
    • Let the engine idle for a few minutes. Warm oil drains out more quickly and removes more contaminants .
  2. Prepare the Motorcycle
    • Set the bike upright on a level surface, using a jack or a wooden block if needed .
    • Ensure the engine is off, and allow it to cool slightly if it's hot.
  3. Drain the Old Oil
    • Place the oil drain pan directly below the engine drain bolt.
    • With the 17 mm socket, carefully loosen and remove the drain bolt.
    • Remove the oil filler cap to allow air in for better drainage .
    • Allow the oil to drain fully—this may take several minutes.
  4. Replace the Oil Filter
    • Locate the oil filter cover, remove its three 8 mm bolts, and carefully take off the cover.
    • Remove the old oil filter and dispose of it properly.
    • Before installing the new filter, ensure O-rings and spring are correctly positioned; lightly oil the new O-ring .
    • Install the new oil filter and reattach the cover, tightening the bolts securely but not over-tightening .
  5. Install the Drain Plug
    • Inspect and replace the crush washer on the drain bolt if needed.
    • Reinstall and torque the drain bolt to 24 N·m (17.5 lb-ft) .
  6. Add New Engine Oil
    • With a funnel, pour in fresh oil (2,000 ml or 2,150 ml if you changed the filter) .
    • Reinstall the oil filler cap.
  7. Check Oil Level
    • Start the engine and let it idle for a couple of minutes while checking for leaks around the drain plug and filter cover.
    • Turn off the engine and wait about five minutes.
    • With the bike upright, check the oil level in the inspection window. The oil should be at or near the “F” mark; add oil if required .
  8. Dispose of Old Oil & Cleanup
    • Bring used oil and filter to a proper recycling facility.
    • Wipe up any spills and recheck all fasteners after a short test ride.

Important Model-Specific Call-Outs for the 1995 DR650S

  • Oil quantities are lower for this year compared to later models. Do not overfill; always check the window .
  • Use only oils of the correct API and viscosity classification. Avoid automotive oils with friction modifiers.
  • The inspection window is small. Allow oil to settle before checking to avoid overfilling .
  • The drain bolt and oil filter cover have been unchanged on DR650S models since the early 1990s. Always double-check torque specs and gasket/O-ring condition .

Maintenance Interval Recommendations

  • Change engine oil every 6,000 km (about 4,000 miles) or every 12 months, whichever comes first .
  • Change oil filter at the initial 1,000 km, then every 12,000 km (7,500 miles), or at least every other oil change .

Final Tips

  • Always use new gaskets/O-rings when replacing the oil filter and drain plug to prevent leaks.
  • Allow the engine to idle and re-check oil level after the change as the filter and engine passages fill up.
  • Regular oil changes are the best way to prolong the life of your DR650S engine—make it a habit.
