As always, proper tools and attention to detail will ensure you get the job done right. Read this complete guide from MotoSport.com to handle the process with confidence.

Tools and Supplies You’ll Need

  • 13mm socket or spanner (for the main drain bolt)
  • 8mm socket or spanner (for filter covers and screens)
  • Torque wrench (if available, for reinstalling bolts to spec)
  • Fresh oil filter (OEM recommended)
  • 1 liter of 4-stroke engine oil (check your owner's manual for recommended type and viscosity)
  • Clean drain pan
  • Funnel
  • Clean rags
  • Nitrile gloves (optional, to keep your hands clean)
  • Contact cleaner (optional, for cleaning parts before reassembly)

Step-by-Step Instructions

1. Preparation

  • Warm up the engine for a couple of minutes to help the oil drain more effectively.
  • Stabilize your bike on its stand or lift, and turn off the ignition.
  • Remove the skid plate. On the 2014 KTM 350 EXC-F, simply turn the locking pin and lift the plate off. This design makes access to the drain plug quick and easy.

2. Draining the Oil

  • Locate the 13mm drain bolt on the left side of the engine.
  • Position your drain pan beneath the drain bolt and oil screen area.
  • Slowly loosen the drain bolt, putting slight pressure toward the engine to prevent it from falling into the pan.
  • Once the oil is draining, remove the oil screen (if equipped) with your 8mm socket for a thorough flush.

  • Allow all oil to drain completely.

3. Removing and Replacing the Oil Filter

  • Use the 8mm socket to remove the oil filter housing cover on the left side of the bike.
  • Remove the old oil filter, noting its orientation.
  • Before installing the new filter, prime it by filling the filter cavity about one-third full with fresh oil (KTM recommends laying the bike on its right side to keep the cavity upright). This step improves oil pressure on start-up.

  • Insert the new filter, then reinstall the cover and tighten by hand before applying final torque (7.4 Nm; do not overtighten).

4. Reinstalling the Drain Plug and Oil Screen

  • Clean the drain plug, replace the crush washer if necessary, and reinstall. Torque to specification if possible. The oil screen should also be cleaned and reinstalled securely

    .

5. Refilling with Oil

  • Remove the oil fill cap (on the right side of the engine) and insert a funnel.
  • Pour in approximately 1 liter of oil. A little less may be required – refer to your manual for the exact capacity.
  • Return the bike to an upright position.
  • Start the engine for 20–30 seconds, then switch off and allow the oil to settle.
  • Check the oil level in the sight glass: it should be halfway up the circle.

  • Add oil as necessary, then replace the fill cap.

6. Final Checks and Clean-Up

  • Inspect for leaks around the drain bolt, filter cover, and oil screen.
  • Wipe down any spills and reinstall the skid plate.
  • Dispose of used oil and the old filter according to local regulations.

Model-Specific Call-Outs for the 2014 KTM 350 EXC-F

  • Skid Plate Removal: The 2014's OEM skid plate uses a simple twist-lock pin, making it among the easiest models for plate removal.

  • Oil Capacity: Confirm your exact oil capacity in the owner's manual. Typically, 1 liter covers the change but always check after cycling the engine.

  • Filter Priming: Lay the bike on its right side and fill the filter cavity one-third before inserting the new filter to protect the engine on first start-up.

  • Torque Specs: For all filter and screen covers, use very light torque — 7.4 Nm — to avoid stripping aluminum threads. Tighten by hand first and only snug with tools.

  • Oil Change Interval: KTM recommends changing oil every 15 hours for heavy/frequent use but intervals of up to 30 hours are generally safe with light riding.

  • Reset Trip/Hour Meter: Some riders use the trip or hour meter to track oil changes — reset after each service for easy maintenance logging.

Pro Tips from MotoSport.com

  • Always use a high-quality filter (OEM recommended) for best engine health.
  • Replace aluminum crush washers periodically to prevent leaks.
  • Keep a service log with dates and hours for resale value and long-term care.
  • Never overtighten bolts into the engine case—stripped threads can be costly to repair.
  • Dispose of old oil responsibly; many MotoSport locations or local auto parts stores will help.

Performing regular oil changes on your 2014 KTM 350 EXC-F is quick, easy, and crucial for engine longevity. With these model-specific call-outs and MotoSport.com’s trusted instructions, you’re ready for smooth riding all season long.
