Regular oil changes are crucial to keeping your 2013 KTM 350SXF performing at its best. This guide provides everything you need to know, including all tools, supplies, and unique KTM-specific tips. All instructions are written specifically for the 2013 350SXF but apply to similar model years with noted specifics.

Tools & Supplies Needed

  • 13mm socket or T-handle (for drain bolt)
  • 8mm socket or T-handle (for oil filter cover)
  • Torque wrench (range: 7-12 Nm)
  • Pick tool (for removing oil screen strainer)
  • Pliers (optional, for oil filter removal)
  • Contact or brake cleaner (for cleaning screens and bolts)
  • Drain pan
  • Funnel
  • Fresh engine oil (KTM recommends 15W-50 full synthetic, 1L)
  • New oil filter (OEM recommended)
  • New copper washers or sealing rings (for drain bolt and oil screen plug)
  • Clean shop rag

Step-by-Step Instructions

  • Warm up the Engine
    • Start the bike and let it idle for 2-3 minutes to warm the oil. Warm oil drains faster and captures more debris.
  • Position the Bike
    • Turn off the engine. Set the bike upright on a stand, ensuring it is level.
  • Remove Skid Plate (if equipped)
    • If your bike has a skid plate, use the KTM quick-release pin or appropriate tool to remove it for easy access to drain bolts.
  • Remove Oil Filler Cap
    • On the right side of the bike, remove the oil filler cap to allow for faster draining.
  • Drain the Oil
    • Place a drain pan under the engine. Locate the main drain bolt underneath the engine (13mm). Carefully remove it and let the oil drain completely.
    • Model-specific note: KTM 350SXF uses a magnetic drain plug. Inspect it for metal shavings; small particles are normal, but large chips or high quantity can indicate engine trouble.
  • Remove and Clean Oil Screen Strainer
    • Locate the oil screen plug next to the main drain. Remove the 13mm plug. Use a pick tool to carefully pry the mesh screen strainer out.
    • Clean the strainer with contact/brake cleaner until all debris is gone. Dry and inspect for wear or damage.
  • Remove & Replace Oil Filter
    • On the opposite side of the bike, remove the oil filter cover (2x 8mm bolts).
    • Allow residual oil to drain.
    • Pull out the old oil filter with pliers or your fingers.
    • Wipe the filter compartment clean, remove any gasket debris. Inspect cover O-rings and replace if damaged.
    • Install the new oil filter.
  • Reinstall Oil Screen & Drain Plug
    • Fit the cleaned oil screen back into its housing.
    • Install a new copper washer/sealing ring on the oil screen plug and main drain bolt before threading in by hand to avoid cross-threading.
    • Tighten both gently. For reference: torque the main drain bolt and screen plug to 10 Nm (7.4 ft-lb) as per KTM spec for most small bolts. Overtightening can strip threads.
  • Replace Oil Filter Cover
    • Install the oil filter cover and tighten the 8mm bolts hand tight, or to 7.4 Nm.
  • Add New Oil
    • Using a funnel, pour in 1 liter of fresh 15W-50 full synthetic oil.
    • Reinstall the oil filler cap securely.
  • Check Oil Level
    • Start the bike, let run for 30 seconds, and shut down.
    • Wait one minute. Use the sight glass (right engine case) to ensure oil is at or just below the middle of the window's circle.
    • Add a small amount of oil if low. Do not overfill.
  • Reinstall Skid Plate (if equipped)
  • Dispose of Old Oil Properly
    • Take used oil to a recycling center or auto store that accepts waste oil.

Special Tips & Call-outs for 2013 KTM 350SXF Owners

  • The magnetic drain bolt is unique to KTM: always inspect for abnormal debris, and clean thoroughly before reinstalling.
  • The oil screen strainer can stick inside the case. Use care when prying it out–never use excessive force to avoid damaging the strainer or engine case.
  • Proper thread care is critical on KTM cases: always start all bolts by hand and avoid overtightening. This model is known for having delicate aluminum threads, so use a torque wrench for best results.
  • The recommended oil volume for this model is 1 liter. Verify via the sight glass after running the engine, especially if your bike has had previous engine or case work done.
  • If you notice milky or frothy oil, it can indicate water contamination. Address immediately to prevent engine damage.

Final Inspection

  • Check around the drain bolt, oil screen, and filter cover for leaks after your first ride post-change.
  • Re-check the oil level after your next ride, especially if you are new to KTM maintenance.
