Routine oil changes are essential for maintaining the performance and longevity of your 2019 KTM 350 EXC-F. While this process is straightforward, KTM has specific requirements for the EXC-F that owners should be aware of. Below is a comprehensive, proprietary guide covering the necessary tools, step-by-step procedure, and model-specific tips for a successful oil change on your KTM 350 EXC-F.

Tools and Supplies Needed

  • 13mm wrench or socket: For drain bolts and oil screen cap
  • Drain pan
  • Torque wrench
  • Measuring cup: For accurate oil refill
  • Clean rags or shop towels
  • Parts cleaning brush
  • Replacement oil filter (OEM-recommended)
  • Replacement crush washer and O-rings (as needed)
  • Engine oil—Motorex Cross Power 4T 10W-50 (KTM recommended)
  • Paper funnel or plastic funnel
  • Contact cleaner: For cleanup
  • Nitrile gloves (optional, for a cleaner job)

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    • Start your motorcycle and let it idle for 2-3 minutes. This helps the oil flow out more easily and suspends debris for removal.
    • Shut off the bike and place it on a stable stand or use the side stand.
  2. Remove Skid Plate (if equipped)
    • Use the appropriate wrench to take off the factory skid plate for easier access to the drain bolts and the oil screen.
  3. Drain Old Oil
    • Place your oil drain pan directly beneath the engine. Remove the main drain bolt (13mm) under the bike; be mindful of the copper crush washer and do not lose it.
    • Allow several minutes for the oil to drain completely.
  4. Clean and Inspect Drain Bolt
    • The drain bolt has a magnetic tip—clean off any fine metallic debris before reinstalling.
    • Inspect the copper or aluminum crush washer and replace if it's deformed or damaged.
  5. Remove and Inspect Oil Screen
    • The KTM 350 EXC-F features an additional oil screen accessed via a second bolt (also 13mm). Remove the screen carefully and inspect for debris.
    • Check the O-ring on the oil screen cap; replace if worn or damaged.
    • Clean the screen with contact cleaner or solvent, allow to dry thoroughly, and reinstall.
  6. Replace the Oil Filter
    • Use pliers, a socket, or your hands to remove the oil filter cover on the engine's side.
    • Pull out the old oil filter and dispose of it properly.
    • Before installing the new filter, fill the filter cavity about one-third full with new oil to help prime the oil pump (especially important on this KTM model).
    • Insert the new filter and replace the cover, ensuring the O-ring is in good shape.
  7. Reinstall Drain Bolt and Screen Cap
    • Hand-thread bolts before tightening. Use a torque wrench to tighten to manufacturer's specs (consult your service manual, but typically around 15 Nm for drain and screen bolts).
  8. Add New Engine Oil
    • Remove the oil fill cap atop the engine and use a funnel to add oil.
    • The 2019 KTM 350 EXC-F calls for approximately 1.2 liters (1.3 US quarts) of oil (always check your owner's manual for exact volume) .
  9. Check Oil Level and Final Inspection
    • Start the engine and let it idle for 30 seconds. Shut it off and wait one minute for oil to settle.
    • Check the oil level using the sight glass or dipstick, and top off if needed.
    • Inspect for leaks around the drain, screen, and filter areas.
  10. Dispose of Used Oil Responsibly
    • Take your used oil and filter to a recycling center or hazardous waste facility. Never pour engine oil on the ground or in drains.

2019 KTM 350 EXC-F: Important Model-Specific Tips & Call-Outs

  • The main drain bolt uses a copper washer, and the oil screen cap uses an O-ring. Replace both if they show any wear or leakage to prevent future oil leaks.
  • The KTM EXC-F series features a magnetic drain bolt—always check for accumulated metal shavings during each oil change.
  • Fill the oil filter housing 1/3 full with oil before installing the new filter—failure to do so can cause a temporary oil starvation condition at startup.
  • It's recommended to change your oil every 10–15 hours of use, or sooner in harsh conditions, to maximize engine life.
  • Always tighten bolts to manufacturer torque specs; overtightening can crack the engine case or crush washers/O-rings.
  • Keep any spilled oil away from tires, brakes, and plastics as it can cause slippage and degrade finishes.
