Shop parts for a 2020 Honda XR650L Dirt Bike.

Regular oil changes are essential to keep your 2020 Honda XR650L running at peak performance and protect its engine. The XR650L's air-cooled, single-cylinder design is straightforward, but Honda's unique dry-sump oiling system means oil must be drained both from the crankcase and the frame. Here’s a step-by-step guide designed specifically for owners of the 2020 XR650L. This guide is proprietary to MotoSport.com.

Tools and Supplies Needed

  • Socket set (including 12mm and 10mm sockets)
  • Ratchet and extension
  • Oil filter wrench or appropriate socket
  • Oil catch pan
  • Funnel
  • Contact cleaner or degreaser
  • Clean rags or paper towels
  • Rubber gloves and safety glasses
  • Replacement crush washers for the drain bolts
  • New oil filter (Honda genuine or exact equivalent)
  • New engine oil (high-quality 10W-40 motorcycle oil recommended)

Oil Specification & Capacity

  • Oil type: 10W-40 high-quality motorcycle oil (brands like Mobil 1, Castrol, Motul recommended)
  • Capacity: Approximately 2.06 US quarts (1.95 L) with filter change

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    Start and let your XR650L idle for 3-5 minutes to thin the oil, making it easier to drain and more effective at removing contaminants. Always perform this in a well-ventilated area.
    Important: Turn off the engine and allow it to sit for 2-3 minutes to let the oil settle into the sump.
  2. Remove the Skid Plate (if equipped)
    If your bike has a skid plate or engine crash bar, remove these first using the correct sockets.
  3. Prepare Your Work Area
    Park the motorcycle on a firm, level surface. Place the oil catch pan beneath the engine.
  4. Remove the Oil Fill Cap/Dipstick
    Unscrew the oil fill cap/dipstick on the frame’s oil reservoir near the steering head. This allows the oil to drain freely without creating a vacuum.
  5. Drain the Old Oil
    Locate and remove the two drain bolts: one on the bottom of the crankcase, one on the front down tube (frame). These are typically 12mm.
    – Allow the oil to drain fully from both locations.
    – Remove and replace the crush washers on each drain bolt to ensure a good seal and prevent leaks.
  6. Remove and Replace the Oil Filter
    – The oil filter is located on the left side of the engine.
    – Remove the three 8mm bolts securing the oil filter cover.
    – Remove the cover, spring, and old oil filter.
    – Clean the filter cover and sealing surfaces.
    – Replace the O-ring on the cover and apply a thin film of new oil.
    – Insert the new oil filter with the OUT-SIDE marking facing out.
    – Reinstall the spring, cover, and bolts. Tighten bolts to 9 lbf·ft (12 N·m).
    Note: Using an incorrect filter or missing the O-ring can result in engine damage. Always use the Honda-specified filter for the XR650L.
  7. Inspect the Oil Screen (every 3-4 oil changes)
    – The XR650L has an oil screen in addition to the filter. On every third or fourth oil change, remove and rinse the oil screen with solvent, then reinstall.
  8. Reinstall Drain Bolts
    – Install new crush washers.
    – Reinstall the drain bolts (crankcase and frame) and torque them to Honda’s specifications (typically around 22 lbf·ft, but always check your owner’s manual).
  9. Fill With New Oil
    – Place a funnel in the oil fill hole.
    – Pour in the recommended amount of new oil (about 2 quarts).
    – Reinstall the dipstick, but do not overtighten.
  10. Check Oil Level
    – Start the engine and let it idle for about 1 minute.
    – Shut off and allow oil to settle for 2 minutes.
    – Remove the dipstick, clean, reinsert (without threading), and check oil level.
    – Top off if necessary.
  11. Clean Up
    – Wipe up any spilled oil with contact cleaner or a rag.
    – Properly dispose of old oil and filter at a recycling center.

2020 XR650L Model-Specific Call-Outs

  • Dry-Sump System: Unique to the XR650L, you must drain oil from both the crankcase and the frame’s down tube. Failing to do so leaves old oil in the system, risking engine damage.
  • Best Oil Filter: Always use Honda genuine or exact-fit aftermarket filters to prevent oil bypass or improper fit.
  • Frame Oil Bolt: The down tube/frame drain is sometimes overlooked; always drain both points.
  • Oil Screen Service: Clean the oil screen every 3-4 changes for long-term engine health.
  • Recommended Oil: Use only high-grade 10W-40 motorcycle oil–never car oil–as additives differ and the clutch is oil-bathed.
  • Torque Specs: Always use a torque wrench for both oil and filter cover bolts to avoid stripping threads in the soft aluminum engine casing.

Final Tips

  • Change oil every 2,000–3,000 miles or once annually, whichever comes first.
  • Record your mileage and oil change date to keep maintenance on track.
