Model-Specific Callouts for 2017 KTM 350SXF
- Your KTM 350SXF uses 1.1 liters of oil—do not overfill or underfill. Check using the sight glass located behind the brake lever once oil is added and engine is warm or cold.
- Use Motorex 10W-50 synthetic oil for best engine protection and warranty compliance.
- This model's oil check sight glass requires pushing the rear brake pedal down to get a clear reading
- There are two bolts to remove: first, the large drain plug for fast draining; second, the oil screen cap, which needs gentle handling and minimal torque (about 7–10 ft-lbs).
- Always prime your oil filter (optional)—consider briefly turning the engine over with the kill switch engaged to circulate fresh oil before running the engine fully.
Step-By-Step Oil Change Instructions
- Warm up the engine for a few minutes to thin the oil and help contaminants suspend, ensuring a more effective drain.
- Place your KTM upright on a stand and position the drain pan beneath the engine.
- Remove the skid plate if equipped, for easier access.
- Remove the drain bolt (under the engine, usually 13mm socket) and let the old oil drain completely. Clean the drain bolt and replace the crush washer with a new one—this step helps prevent leaks.
- Remove the oil screen cover and slide out the oil screen. Clean the oil screen with contact cleaner or solvent, then inspect for debris.
- Remove and replace the oil filter (side cover, usually 8mm). Insert the new filter and ensure the O-ring is clean and lightly greased. Set the cover back on and torque to specification (about 7.4 Nm or 5.5 ft-lbs).
- Reinstall the oil screen and drain bolt. Hand-tighten to avoid cross-threading, then snug them with your torque wrench—never overtighten.
- Add fresh oil. Remove the oil fill cap (right side), insert a funnel, and pour in 1.1 liters of oil. Go slowly to avoid spills.
- Prime the system by holding the stop button and turning the starter just a couple seconds—this circulates oil through the filter before full start-up.
- Start the bike and check for leaks. Let it idle for 30 seconds, then shut off. Inspect drain plug, screen cover, and filter for any oil seepage.
- Check oil level via sight glass. With the bike upright and the brake pedal pushed down, verify oil is between the middle and the top of the glass. Top off if necessary.
- Properly dispose of old oil at your local recycling center; never pour into storm drains or trash.
Extra Maintenance Tips for 2017 KTM 350SXF Owners
- Check and change oil every 10-15 hours under aggressive riding; follow KTM's service schedule for less frequent use.
- Inspect old oil for metallic particles or unusual debris—these could indicate abnormal engine wear.
- Wipe up any spilled oil with a clean rag and use contact cleaner for a spotless job.
- Don't overtighten fasteners; aluminum threads in your KTM's engine cases are easily stripped.
