Step-By-Step Instructions
-
Warm Up the Engine
Run the bike for 3-5 minutes. This thins the oil, letting it drain faster and more completely. -
Stabilize the Dirt Bike
Place the KTM 250XCF on a stand so it sits upright and stable. -
Remove the Skid Plate
If equipped, use the appropriate tool to remove the skid plate for easy access to drain bolts. -
Locate and Remove the Drain Bolts
- The 2018 KTM 250XCF uses two oil drain plugs (main and for the oil screen) and an oil filter cover.
- Place the drain pan beneath the engine. Remove both drain bolts (typically with a 13mm socket).
- Remove the oil fill cap to help the oil drain freely.
-
Remove and Clean Oil Screens
- Each plug secures an oil screen. Carefully pull out each screen.
- Thoroughly clean with contact cleaner and inspect for debris or metal shavings (a little is normal, but excessive metal may indicate engine wear).
-
Replace or Clean the Oil Filter
- Remove the filter cover (8mm socket). Watch for oil drips.
- Pull the filter with pliers or by hand.
- Install a new oil filter and check/replace the cover O-ring.
-
Inspect and Replace Crush Washers
- Always use new crush washers on both drain bolts to prevent leaks. Replace as needed.
-
Reinstall Oil Screens and Drain Bolts
- Slide the cleaned screens back in. Install drain plugs by hand first, then tighten to KTM's specified torque with a wrench (do not over-tighten to avoid damaging engine cases).
-
Add Fresh Oil
- Using a funnel, pour in 1.0 liter of engine oil (Motorex 10W50 recommended).
- Replace the oil fill cap.
-
Prime the Oil System (Optional but Recommended)
- With the kill switch held, turn the engine over several seconds (electric start) to help pre-lubricate the filter area before a complete start.
-
Start the Engine and Circulate Oil
- Start the bike and let it idle for 2-3 minutes. Shut off and let oil settle several minutes.
- Check for leaks at the drain bolts and filter cover. Wipe up any mess with contact cleaner.
-
Check Oil Level
- With the bike level, check the oil sight glass on the right crankcase. The oil should be at halfway to top of the sight glass. Top up as needed, but do not overfill.
- Reinstall skid plate if removed.
2018 KTM 250XCF Model-Specific Tips
- The engine uses two oil screens for extra engine protection. Clean both screens every oil change.
- Oil change volume is approximately 1.0 liter with filter, but always use the sight glass for final adjustment, not just volume measured.
- Take extreme care not to over-tighten drain bolts—stripped threads in the case are a common and costly issue. Always torque to manufacturer spec (consult owner's manual).
- This model's oil filter sits horizontally—be sure the filter cover O-ring is properly seated to prevent leaks.
- Doing frequent oil changes is especially important on high-revving, four-stroke race engines like the 250XCF.
