Step-by-Step Instructions
-
Warm Up the Engine
- Start your XR650L and let it idle for a few minutes to warm up the oil. This lowers viscosity, allowing the oil to drain more thoroughly and completely.
-
Remove the Oil Dipstick
- With the engine off, unscrew the oil dipstick from the frame to help vent the system during draining, preventing vacuum lock and ensuring a faster drain.
-
Drain the Engine Oil
- Locate the main drain bolt under the engine, close to the header pipe, using a 17mm socket. Make sure your drain pan is positioned to catch the oil.
- Loosen the bolt, let the oil drain completely. Replace the crush washer as needed.
- Torque to factory specs (typically 29 ft-lbs for this model) upon reinstallation.
-
Drain the Oil from the Down Tube
- Locate the second drain bolt on the frame's down tube (uses a 10mm socket). Oil will shoot out briskly–ensure your pan is positioned accordingly.
- Clean the bolt and re-install with a new crush washer.
-
Service the Oil Screen (Recommended Every 3rd or 4th Oil Change)
- The oil line screen helps prevent contaminants from circulating. Remove the engine guard (8mm socket) to access the oil line and the oil screen within.
- Remove and inspect the screen; clean it with contact cleaner or replace if damaged.
-
Replace the Oil Filter
- Locate and remove the oil filter cover (12mm).
- Use an oil filter wrench if needed.
- Install the new oil filter, ensuring the O-ring is properly seated and lubricated with a bit of fresh oil.
- Torque the cover bolts to factory specification; do not over-tighten.
-
Pour in New Oil
- Reinsert all bolts and confirm everything is secure.
- Using a funnel, add about 1.0 quart of 10W-40 motorcycle oil into the oil fill cap opening on the frame. The total capacity is 2.06 quarts.
- Start the engine briefly (1 minute), then power down and continue to add the remaining oil incrementally until it measures correctly on the dipstick with the bike leveled upright.
-
Check for Leaks & Reinstall the Dipstick
- Inspect for oil leaks from the drain plugs, oil filter, and down tube after the engine idles.
- Clean any spillage using contact cleaner and a rag.
- Reinstall the oil dipstick.
-
Final Oil Level Check
- Bring the bike up to operating temperature, shut down, and let it sit for a couple of minutes. With the bike upright and level, check the oil level with the dipstick (do not screw in for the check); add oil if needed.
