Keeping your 2014 KTM 350SXF's oil fresh is one of the most important maintenance tasks you can perform for top performance and engine longevity. This step-by-step guide lays out the tools, steps, and crucial call-outs unique to this model. Let's keep your KTM 350SXF running like a champ and ensure your oil change is done right by following these detailed instructions.
Tools & Supplies You'll Need
- 8mm socket and ratchet (for oil filter cover bolts)
- 13mm socket and ratchet (for drain plug)
- Torque wrench (for reinstalling bolts precisely)
- Circlip pliers (helpful for pulling the oil filter)
- Drain pan
- Rags and contact cleaner (clean-up & oil filter area cleaning)
- Funnel
- Replacement oil filter (OEM recommended)
- Crush washer (replace the old one on the drain bolt)
- Fresh engine oil (see manufacturer's recommendation; typically 1.1L – 1.2L of high-quality 4-stroke motorcycle oil, Motorex is a common KTM spec)
- Gloves (optional, to keep your hands clean)
- Skid plate removal tool (if your bike's skid plate covers the drain plug)
Specific Call-Outs for the 2014 KTM 350SXF
- This model uses two screens plus an oil filter. Don't skip cleaning the screens; they trap debris missed by the filter.
- Oil capacity is 1.1L (performing a filter and oil change). Some first-gen models require slightly less — always check your owner's manual.
- The sight glass for checking oil level is partly hidden behind the brake pedal; you'll need to push the pedal down for a clear view.
- Torque your bolts carefully. Too tight can strip threads; too loose can cause leaks.
- Warm up the bike for a few minutes before draining oil to ensure it drains thoroughly and brings contaminants with it.
Step-by-Step: Oil Change Instructions
-
Warm Up the Engine
Start and run your KTM 350SXF for 3-5 minutes. This helps thin the oil for better draining and brings debris into suspension. -
Secure the Bike
Place the bike on a stand so it's upright and level. Turn off the engine and make sure everything is cool enough to handle safely. -
Remove the Skid Plate (if applicable)
Use the proper tool to release the pin or bolts and gently set the plate aside.
Pro tip: The KTM uses a quick-release pin on some models; just twist and drop the plate off the frame for easy access.
-
Drain the Old Oil
Place a drain pan beneath the engine. Using a 13mm socket, remove the main drain plug on the left side of the case.
Be careful. Apply slight inward pressure when unscrewing the plug to prevent oil spilling out too soon.
Allow the oil to drain completely.
-
Remove Oil Screens
There are two oil screens (one on each side of the crankcase, covered by small bolts/caps). Unscrew and carefully pull them out. Clean any debris from the screens with contact cleaner and a rag.
-
Replace or Clean the Drain Plug and Install New Crush Washer
Inspect the plug's threads and magnets for damage or metal shavings. Replace the crush washer every oil change to ensure a leak-free seal.
Reinstall the plug, tightening to 20 Nm (14.8 ft-lbs) using your torque wrench.
-
Remove and Replace the Oil Filter
On the right side of the engine, use an 8mm socket to remove the oil filter cover bolts. Carefully pull the cover (it's sealed tightly by an O-ring).
Use circlip pliers if needed to extract the filter. Clean the filter area thoroughly.
Pre-oil the new filter by adding a little fresh oil inside before installation.
Push the new filter in and ensure it seats completely.
Inspect the O-ring on the filter cap; replace if damaged.
Reinstall and torque the cover bolts to 7.4 Nm (or "snug," very low torque).
-
Clean and Reinstall the Oil Screens
Reinsert the cleaned screens. Install the caps and torque to 15 Nm (11 ft-lbs).
-
Add Fresh Oil
Remove the oil fill cap and insert a funnel.
Pour in 1.1 liters of recommended oil (Motorex or similar), stopping occasionally to let the oil settle.
Replace and tighten the oil fill cap securely. -
Check the Oil Level
Allow a minute for the oil to settle. On the 2014 KTM 350SXF, the sight glass is behind the brake pedal. Depress the pedal so you can see. Proper level is between the halfway and top marks on the sight glass.
-
Start the Engine and Re-Check
Start the bike and let it idle for 2-3 minutes. Shut it off and let it sit for a couple more minutes.
Recheck the oil level. Add a bit more oil if it's low; do not overfill.
-
Final Safety Checks
Double-check for leaks around the drain plug, oil screens, and filter cap.
Wipe down any oil residue. -
Reinstall Skid Plate
Set the skid plate back in place, secure the pin or bolts, and ensure proper fitment.
Rider Notes and Model-Specific Reminders
- Only use manufacturer-recommended oil. Engine longevity depends on proper lubrication and detergent additives.
- Record the service date and odometer reading for future reference.
- The 350SXF's twin oil screens are critical; always clean them, not just the filter.
- Proper torque matters: overtightening bolts can strip soft aluminum threads; use a torque wrench throughout.
- Always replace crush washers and O-rings as needed for a leak-free result.
