Tools and Supplies Needed

  • 12mm socket and ratchet
  • Oil catch pan
  • Funnel
  • Measuring cup or graduated container
  • New engine oil (Honda recommends high-quality 4-stroke motorcycle oil)
  • New oil filter
  • Replacement sealing washers for drain bolts
  • Rags or shop towels
  • Contact cleaner (optional, for cleanup)
  • Torque wrench (recommended)

Oil Specifications and Quantities

  • Engine oil capacity (with filter change): 2.06 US quarts (1.95 liters)
  • Recommended oil type: 10W-40 or 20W-50 (check your climate and riding conditions)
  • Drain bolt torque: 29 ft-lbs (39 N·m)
  • Oil strainer/frame bolt torque: 40 ft-lbs (54 N·m)

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    • Start the bike and let it idle for a few minutes. This allows the oil to warm up, making it easier to drain completely.
  2. Locate the Drain Plugs
    • The 2004 XR650R has two drain bolts:
      • Engine crankcase drain bolt: Under the engine, right side, slightly behind the front of the shifter.
      • Downtube/frame drain bolt: On the frame downtube, below the exhaust header.
  3. Drain the Oil
    • Place your oil catch pan under the crankcase drain bolt. Use the 12mm socket to remove the bolt and allow oil to drain fully.
    • Once oil has slowed, move the catch pan to the downtube drain and remove the 12mm bolt to drain the frame oil reservoir as well.
    • Inspect and replace sealing washers if necessary.
    • Clean any residual oil with a rag or contact cleaner.
  4. Remove and Replace the Oil Filter
    • Remove the oil filter cover with the appropriate tool.
    • Take out the old oil filter, noting its orientation.
    • Install the new filter in the same orientation.
    • Replace the cover, tightening bolts evenly to prevent leaks.
  5. Clean and Inspect Drain Bolts
    • If using a magnetic drain plug (recommended), check for metal debris.
    • Clean plug thoroughly before reinstalling with a new washer.
  6. Reinstall the Drain Bolts
    • Torque the crankcase drain bolt to 29 ft-lbs (39 Nm).
    • Torque the upper frame downtube bolt to 40 ft-lbs (54 Nm).
  7. Add New Oil
    • Using a funnel, pour in 1.0 quart (0.95 L) of the total oil requirement through the oil fill cap on the right side of the frame or head tube.
    • Reinstall the fill cap and start the engine. Let it idle for one minute, then shut it off and add the remaining oil.
    • Total oil capacity (with filter change) should be 2.06 US quarts (1.95L).
  8. Check Oil Level
    • With the bike upright and level, remove the dipstick, clean, reinstall without threading, and check the oil level.
    • Add oil if necessary to bring up to the "full" mark.
    • Important: Oil level on a hot engine is most accurate. Too much oil can cause it to vent into the airbox, too little can starve the engine.
  9. Cleanup
    • Wipe away oil drips, dispose of used oil and filter properly, and rinse hands and tools.

Special Call-outs for the 2004 Honda XR650R

  • Dual Drain Points: Unlike many dirt bikes, the XR650R uses a dry-sump system with both crankcase and frame drains. For a complete oil change, you must drain both locations.
  • Proper Oil Check: Always check the oil when hot, and with the bike held upright–not on the sidestand<a></a>.
  • Overfilling: Overfilling can cause oil to be forced into the airbox, making a mess and potentially affecting performance.
  • Drain Bolt Sealing Washers: Replace them at each change to avoid leaks.
  • Torque Specs: Following the specified torque prevents stripped threads and oil leaks.

Tips for Longevity and Performance

  • Change oil every 1,000 miles or sooner if riding in extreme conditions.
  • Inspect for metal particles on drain plug magnets as signs of bearing or transmission wear.
  • Always use high-quality oil and filters designed for motorcycles.
  • Keep records of maintenance for resale value and troubleshooting.

Following these steps will ensure your 2004 Honda XR650R continues to perform at its best. For additional OEM parts or high-performance upgrades, shop with confidence at MotoSport.com.
