Step-by-Step Oil Change Instructions
-
Preparation
- Park the bike on a level surface and ensure it is stable (preferably on a lift or center stand).
- Gather all tools and supplies before starting.
- For safety, wear gloves and glasses. Use the service manual for torque specifications and additional reference.
-
Warm Up the Engine
- Run the engine for several minutes to thin the old oil, making it easier to drain completely and more effectively remove contaminants.
-
Remove Skid Plate If Equipped
- If your XR650L is equipped with a skid plate or engine crash bar, remove it to access the drain plugs easily.
-
Remove Filler Cap/Dipstick
- Unscrew the oil fill cap/dipstick. This prevents a vacuum and allows oil to drain more freely.
-
Drain the Engine Oil (Crankcase)
- Place an oil catch pan beneath the engine.
- Using a 17mm socket or wrench, remove the main engine oil drain bolt (beneath the head pipe). Allow oil to drain completely. Replace the crush washer on the bolt.
-
Drain the Oil from the Frame Reservoir
- Locate the frame down tube drain bolt (usually 10mm). Position your drain pan carefully; oil may squirt out under some pressure.
- Remove the bolt, allow oil to drain, then replace with a fresh crush washer. Don’t overtighten; reference the service manual for proper torque.
-
Clean the Oil Screen (Every 3-4 Changes)
- There is an oil screen in the oil line, accessible with the drain. Remove and wash it with solvent or contact cleaner as needed, then reinstall it.
-
Replace the Oil Filter
- Use an oil filter wrench to remove the filter cover bolts and then the filter itself.
- Install the new filter, making sure it seats properly. Lubricate the seal with a bit of fresh oil before installation.
-
Reinstall All Drain Bolts and Fill Cap
- Check that all drain bolts (crankcase and frame) are securely torqued, but not overtightened. Install a new crush washer if needed.
- Clean up any spilled oil with contact cleaner and rags.
-
Add New Oil
- Using a funnel, pour approximately 2.0 quarts (2.06 quarts) of 10W-40 motorcycle oil into the fill port.
-
Check Oil Level
- Reinstall the dipstick, start the engine, and let it run for 1-2 minutes. Turn it off, wait 2-3 minutes, then check the level again.
- Top off if necessary. Do not overfill.
-
Dispose of Old Oil Responsibly
- Take the waste oil and used filter to a certified recycling facility or hazardous waste collection center.
Additional Notes
- Check for leaks around drain plugs and the oil filter after finishing the procedure and running the bike.
- Keep a log to track oil changes and oil screen cleaning intervals.
- This oil change procedure applies specifically to the 2003 Honda XR650L and most years of the XR650L family, though always check your owner’s manual for model-specific instructions and torque values.
