Below you'll find everything you need to perform a robust, professional oil change—proprietary to MotoSport.com—with attention to the particular needs of the 2023 KTM 350XCF Factory Edition.

Tools and Materials Needed

  • 13mm socket
  • 8mm socket
  • 13mm wrench
  • Pliers (for removing the oil screen)
  • Drain pan (to catch old oil)
  • Shop rags or paper towels
  • Parts tray (for bolts and small pieces)
  • Fresh engine oil (refer to KTM spec, typically 10W-50 fully synthetic)
  • New oil filter (OEM or equivalent)
  • New crush washer
  • Brake/contact cleaner (for cleaning up spills and parts)
  • Measuring cup (for precise oil fill, typically 1 liter)
  • Paper funnel (to avoid spills)
  • Grease (for reassembling seals if necessary)

Preparation

  • Warm up the engine by running it for a couple of minutes. Warm oil will drain better and carry away more residue from inside the engine.
    Be cautious: surfaces will be hot.
  • Secure the bike upright on a stand or level ground to ensure a complete and clean drain process.
    Tip: Place cardboard or rags around your work area to catch all drips.

Step 1: Draining the Old Oil

  • Locate the 13mm drain bolt on the bottom rear section of the engine case. Place your drain pan beneath the bolt.
  • Remove the drain plug with your 13mm socket or wrench. Allow the oil to drain completely.
    Caution: The oil may be hot.
  • Inspect the drain plug for any metal debris and replace the crush washer with a new one before reinstallation.
  • While oil is draining, remove the oil screen(s) (these are mesh filters that trap debris) with pliers. Clean them thoroughly using brake/contact cleaner. Install the cleaned oil screen(s) before moving on.

Step 2: Changing the Oil Filter

  • Use your 8mm socket to remove the oil filter cover, typically located on the right side of the engine case.
  • Pull out the old oil filter and dispose of it properly.
  • Thoroughly clean the oil filter cavity and sealing surfaces with a shop rag. You can also reach inside with a rag to soak up any remaining dirty oil for a cleaner result.
  • Pre-fill the new filter with fresh oil to ensure the engine isn't starved of lubrication on initial startup.
  • Install the new filter. Refit the cover with its O-ring, ensuring everything is seated properly, and tighten the bolts evenly and securely (do not overtighten).

Step 3: Refilling with Fresh Oil

  • Double-check that your drain bolt, oil screens, and filter cover are securely installed.
  • Measure out the correct amount of oil (usually 1 liter for the 350XCF Factory Edition, but always confirm in your owner's manual).
  • Using a funnel, pour the new oil into the filler cap on top of the engine.
  • Reinstall the filler cap and wipe away any spills with a rag or use brake/contact cleaner.

Step 4: Priming and Final Checks

  • Before starting the engine, hold down the engine cutoff button and use the starter to spin the engine briefly; this circulates oil before combustion starts.
  • Start the bike and let it idle for 30–60 seconds.
  • Shut off the engine and let it sit for a couple of minutes.
  • Check the oil level through the bike's inspection window or dipstick, adding more oil if necessary.
  • Look for leaks at the drain bolt, oil filter cover, and filler cap.

Model-Specific Call-Outs: 2023 KTM 350XCF Factory Edition

  • This bike is part of KTM's latest generation of 250/350cc four-stroke engines (2023–2026), so the drain and filter locations are similar across these years.
  • Always use KTM-recommended oil viscosities (typically 10W-50 full synthetic).
  • The 350XCF Factory Edition uses two oil screens (one for the clutch side, one for the gearbox side) as well as one external oil filter—clean and inspect both screens with each oil change.
  • Tighten all bolts to spec: drain bolt to 10 Nm (7 ft-lb), filter cover bolts to 8 Nm (6 ft-lb). Overtightening can strip threads.
  • Change the oil at recommended intervals—every 15 hours of riding, or sooner under race/harsh conditions.

Conclusion

Regular, careful oil changes are one of the most important things you can do to keep your KTM 350XCF Factory Edition running strong.
