Regular engine oil changes are critical for maintaining the performance and reliability of your 2017 KTM 350 EXC-F. This guide walks you through the process with model-specific tips, ensuring a hassle-free oil change for both new and experienced riders.
Tools and Supplies Needed
- 13mm wrench (for drain bolt)
- Torx bits (to remove the oil filter cover, typically T30 or T40)
- Measuring cup or graduated container (for accurate oil measurement)
- Oil drain pan
- Paper towels or shop rags
- Oil filter (specific to KTM 350 EXC-F)
- Fresh engine oil (see your manual for recommended type and capacity; typical fill is around 1.1 liters)
- New crush washer (often included with oil filter kits)
- Contact cleaner (for cleanup)
- Paper funnel (optional, highly recommended for a clean pour)
- Grease (for O-rings, optional)
- Torque wrench (recommended for precise tightening)
- Bike stand (to securely hold your bike upright or slightly tilted if solo)
Model-Specific Notes – Preparation
- The KTM 350 EXC-F uses a shared engine design from 2012–2023, so this process is similar across these years, but always check your owner's manual for any updates on torque specs or oil capacity for the 2017 model.
Call-out: For this generation, KTM recommends filling the oil filter cavity partially before inserting the new filter to prime the pump and prevent dry starts.
Check all parts are KTM-specific and not cross-compatible with non-KTM replacements. - Make sure to change your oil every 15–20 hours of use, or more frequently in harsh riding conditions.
- Warm up the engine for a few minutes before changing oil to help old oil drain more effectively.
Step-by-Step Instructions
-
Warm the Engine
Start your bike and let it idle for 3–5 minutes. Shutdown and let cool enough to touch the engine without burning yourself. -
Prepare the Area
Place the bike on a stand. Position your oil drain pan underneath the engine's drain bolt. Have all your tools and parts laid out. -
Drain the Oil
Use your 13mm wrench to remove the main oil drain bolt located on the underside of the engine. Let the oil drain completely (“dead easy” process for the 350 EXC-F). Replace the crush washer if necessary when reinstalling the bolt. -
Remove and Replace the Oil Filter
Remove the oil filter cover using the appropriate Torx bit. Take out the old oil filter and dispose of it properly.
KTM Specific Step: Lay the bike on its right-hand side (handlebars against your stand or a stable block) and fill the oil filter cavity about 1/3 to half full with fresh oil. This primes the pump and reduces dry starts.
Insert the new oil filter slowly to allow it to absorb oil without spilling. Gently press into place and reinstall the cover, lightly lubricating the O-ring with a dab of grease if desired. Tighten gently by hand or to spec (7.4 Nm) to avoid overtightening. -
Replace the Drain Bolt
Once all oil has drained, reinstall the drain bolt with the new crush washer. Tighten to the manufacturer's torque spec (commonly 15 Nm for the KTM 350 EXC-F — always verify in your manual for your 2017 model). -
Add Fresh Oil
Remove the oil fill cap on the right side of the engine. Insert your funnel and pour in the specified amount of oil (typically around 1.1 liters, but always check the manual for your 2017 EXC-F).
Tip: Pour slowly to avoid overfilling or spillage. -
Check and Adjust Oil Level
With the bike upright and level, check the oil sight glass on the side of the engine. The oil should be in the middle of the sight glass circle. Add or remove oil as needed. -
Start the Engine & Recheck
Replace the oil fill cap. Start the bike and let it idle for a minute. Shut down and let it sit for a couple of minutes. Recheck the oil level and inspect for leaks around the drain bolt and filter cover. -
Clean Up
Wipe away any excess oil and dispose of the used oil and filter at your nearest recycling center.
Use a contact cleaner as needed to remove any remaining oil residue. -
Reset Oil Maintenance Interval
For models with a trip meter or maintenance reminder, reset your trip or log your hours to keep track of the interval to your next oil change.
2017 KTM 350 EXC-F Owner Call-Outs
- Always prime the oil filter housing before inserting the new filter; this is a KTM requirement to prevent dry start wear on this engine series.
- Check your service manual for exact oil type and capacity—using the wrong viscosity or over/underfilling can impact engine performance.
- Do not overtighten the oil filter cover or drain plug; use a torque wrench if possible to avoid stripping the threads, which is a common issue with this model.
- If performing your first oil change, inspect the old oil and filter for unusually large metal particles, which could indicate early wear or break-in debris—consult your dealer if excessive.
Final Tips
- Keep extra crush washers and oil filters on hand for future changes.
- Maintain a maintenance log to document hours and oil changes—especially important on high-value bikes like the KTM 350 EXC-F.
- Dispose of oil responsibly at an approved facility to protect the environment.
