Oil Change Interval

Step-by-Step Oil Change Instructions
-
Warm Up the Engine:
- Run the bike for a few minutes to bring the engine and oil up to operating temperature. This helps the oil drain faster and more thoroughly.
-
Position the Bike:
- Place your bike on a stable, level surface, preferably on a stand to keep it upright and steady while you work.
-
Remove the Oil Filler Cap:
- Unscrew the oil filler cap to allow air into the system as the oil drains. This helps oil flow out more efficiently.
-
Drain the Oil:
- Locate the rear drain plug (13mm head, horizontally mounted at the back end of engine). Place your drain pan underneath and carefully remove this bolt. This plug has a magnet to catch metal debris. Set the plug aside and clean thoroughly with contact cleaner.
- With the bulk of oil draining, move to the second drain plug located in front of the first. Remove this plug; it contains a long oil screen (remove and set aside the screen for cleaning).
- Allow all oil to drain completely. Be cautious; oil and engine parts will be very hot.
-
Clean Components:
- Spray both the magnetic drain plug and long oil screen clean with contact or brake cleaner. Wipe off any fine metal shavings (a small amount is normal). Clean the threads and sealing surfaces on both plugs.
- Check and clean the short oil screen, located under a separate hex-socket plug at the engine bottom. Use a pin-type hex key as needed and gently tap with a hammer if stuck. Remove the screen, clean thoroughly, and check/replace O-rings if damaged (blow through with compressed air if possible).
-
Replace Oil Filters:
- The 2009 KTM 400XCW requires replacing both oil filters. Remove filters according to manual instructions, clean seating areas, and install new filters.
- Lightly coat the O-rings and filter gaskets with fresh oil prior to installation. Replace any crusty or damaged sealing washers.
-
Reinstall Plugs and Filters:
- Reinstall drain plugs (with new or cleaned sealing washers) and tighten to the recommended torque spec (20 Nm is a typical value, but check your manual for confirmation).
- Carefully install the cleaned long and short oil screens and hex-socket plug, ensuring O-rings are in good condition and properly seated.
-
Refill with Fresh Oil:
- Using a funnel, pour the proper amount and type of motorcycle-specific oil into the filler. The typical fill amount for this model is around 1.7 quarts, but always check your user manual for the precise capacity.
- Replace and tighten the oil filler cap.
-
Start the Engine and Check for Leaks:
- Start the bike and let it idle for a minute. Inspect all seals and plugs for leaks. If leaks are found, immediately shut off the engine and address the problem.
- Allow oil to settle, then check the oil level via sight glass or dipstick. Add oil if necessary, ensuring you do not overfill.
-
Dispose of Old Oil Responsibly:
- Take your used oil to a local recycling or hazardous waste disposal facility.
Specific Call-Outs for 2009 KTM 400XCW Owners

- Both drain plugs (especially the rear/magnetic plug) play a role in catching engine debris—clean thoroughly.
- Using correct torque values is important for plug re-installation; overtightening can damage threads or cases.
- The recommended oil change interval is 15-20 hours or every few months, depending on usage and conditions.
- High heat from a freshly run engine can cause burns—always use caution when draining oil.
Final Notes
