Regular oil changes are one of the most critical maintenance tasks for your 2013 KTM 350XCF.

Follow these steps to keep your dirt bike running at peak performance.

Tools & Supplies Needed

  • 13mm socket or T-handle wrench (for drain plug and oil screen)
  • 8mm socket (for oil filter cover bolts)
  • Torque wrench (optional, for reassembly)
  • Small pick or needle-nose pliers (for removing the oil screen)
  • Drain pan
  • Contact or brake cleaner (for cleaning the oil screen and surrounding areas)
  • Funnel
  • Clean rags or paper towels
  • New oil filter (OEM recommended)
  • New engine oil (typically 10W-50 full synthetic, check your manual for exact amount and type)
  • Gloves

Preparations

  • Let the bike cool down completely before starting, but warm oil drains easier—so a short ride before shutdown can help.
  • Ensure the motorcycle is stable on a stand or flat surface.
  • If equipped, remove the skid plate to access the drain bolt. The KTM has a convenient quick-release pin for this step.

Oil Change Procedure

  1. Locate and Remove the Oil Drain Bolt
    • The drain bolt is under the engine, typically on the left side. Use the 13mm wrench to slowly loosen the bolt while maintaining inward pressure to prevent it from falling into the oil pan.
    • Let the old oil drain completely into your pan. Inspect the magnetic tip of the drain plug for any metal particles—it’s normal to see some, but excessive metal may indicate engine wear.
  2. Remove and Clean the Oil Screen
    • The oil screen is adjacent to the drain plug. Use your 13mm wrench to remove it. If it’s stuck, gently pry it out with a small pick or needle-nose pliers.
    • Thoroughly clean the screen with contact cleaner. Look for metal shavings or debris, as these can indicate internal issues.
  3. Replace or Clean the Oil Filter
    • With an 8mm socket, remove the two bolts securing the oil filter cover—found on the right or left side of your engine casing, depending on the model year.
    • Remove the old oil filter. Some recommend filling the new filter with fresh oil before installation to prevent a dry start, but this is optional.
    • Install the new oil filter, making sure the spring and sealing surfaces are correctly positioned. Lightly oil the O-ring for a good seal.
    • Reattach the oil filter cover and tighten the bolts snugly (they require minimal torque, around 7-8 Nm).
  4. Reinstall the Oil Screen and Drain Plug
    • Ensure both the screen and drain bolt are clean and the O-rings are in good condition. Replace any damaged O-rings to prevent leaks.
    • Thread each one by hand first to avoid cross-threading, then gently torque to manufacturer specifications or just snug by hand.
  5. Add New Oil
    • Remove the oil fill cap (usually on the right side of the engine above the clutch cover).
    • Using a funnel, pour in precisely 1.0 liters (per KTM's specification for the 350XCF, but always double check your owner's manual).
    • Replace the oil cap securely.
  6. Check Oil Level
    • With the bike upright and on a level surface, check the oil sight glass or dipstick.
    • Start the engine and let it idle for 1-2 minutes to circulate the oil, then shut it off, wait a minute, and recheck the oil level.
    • If required, top off to bring the oil level to the center of the sight glass's marked circle.
    • Inspect under the bike for leaks.
  7. Final Inspection and Clean-up
    • Spray any spilled oil off the frame and engine with contact cleaner.
    • Safely dispose of used oil and the filter at an appropriate recycling facility.

2013 KTM 350XCF-Specific Notes

  • Magnetic drain plug: KTM equips its bikes with a magnetic drain bolt—always inspect it for excess metal. A small amount of very fine “fuzz” is typical, but any large fragments should be investigated.
  • Torque values: The oil screen cover bolts and filter cover bolts require very low torque—do not over-tighten, as the threads in the aluminum case can be stripped easily.
  • Drain plug washer: Replace the crush washer on the drain bolt if it appears worn or deformed to prevent leaks.
  • Oil Screens: Your KTM 350XCF has both a main oil screen and a secondary one. Make sure both are cleaned at every oil change.

Tips for Success

  • Use only high-quality oil that meets or exceeds KTM's specifications for optimal clutch performance and engine longevity.
  • Record the service date and hours on the engine to keep up with maintenance intervals.
  • Double-check all fasteners and clean up any spills to avoid dirt attracting to oily surfaces.

Changing the oil on your KTM 350XCF is straightforward and can be completed in under 30 minutes with proper tools and preparation. Consistent maintenance ensures your dirt bike delivers reliable performance—both on the trail and at the track.
