Tools and Materials Needed
- Socket set (including a 13mm socket for the drain plug; common hand tools)
- T-handle wrench and torque wrench
- Oil drain pan
- Funnel
- New oil (KTM recommends 15W50 fully synthetic oil for most conditions)
- New crush washer for the drain plug
- Replacement oil filter and/or inspection/cleaning of oil screens
- Contact cleaner and paper towels or rags
- Service manual (recommended for torque specs and reference)
- Protective gloves (optional but advised for cleanliness)
Pre-Changing Preparation
- Warm the engine for 2-3 minutes. This helps suspended contaminants drain out with the old oil and ensures the oil flows out smoothly. Be careful: the oil and engine parts may be hot.
- Thoroughly clean the bike, especially around the drain plug and oil filler cap, to prevent dirt and debris from contaminating the engine while open.
- Place the bike on a stable stand to keep it level.
Step-by-Step Oil Change for 2000 KTM 250 EXC
-
Remove the Filler Cap
Start by removing the oil fill cap located above the transmission case. This allows air in, which helps the oil drain faster.
Tip: Clean around the cap first to avoid introducing dirt into the engine.
Call-out: Use caution not to misplace the filler cap or introduce anything into the open filler neck while draining the oil. -
Position the Oil Pan
Slide your oil drain pan beneath the engine to catch the old oil.
Call-out: Make sure the pan is large enough (you will be draining up to 0.8 liters of oil). -
Remove the Main Drain Plug
On the 2000 KTM 250 EXC, the main drain plug is usually a 13mm bolt located at the base of the crankcase.
- Loosen and remove the bolt carefully. If the engine is still warm, the oil may flow quickly and be hot.
- Let the oil drain completely; this can take a few minutes.
- Clean the magnetic drain plug welluse a contact cleaner to remove metallic debris to monitor internal wear.
- Replace the crush washer with a new one to prevent future leaks.
-
Remove and Inspect Oil Screens/Filters
The 2000 KTM 250 EXC has a mesh screen and oil filter accessible during the change.
- Locate the long screen (accessible near or under the shifter) and the short screen (underneath the engine near the main drain bolt).
- Carefully remove both screens. Let any residual oil drain.
- Inspect and clean both screens with contact cleaner.
- Replace the oil filter (if equipped) following the manufacturer's guidelines; install a new filter if required.
-
Reinstall Drain Plug and Screens
Once all oil has drained and parts are clean:- Reinstall the cleaned oil screens (or new ones if damaged).
- Thread the main drain bolt in by hand, then tighten using a torque wrench to 20 Nm (14.8 ft-lbs). Overtightening may strip threads or crush gaskets; undertightening can cause leaks.
-
Refill with Fresh Oil
Using a clean funnel, pour 0.8 liters (800 ml) of 15W50 fully synthetic motorcycle oil into the filler opening.
- Pour slowly, pausing if needed to let the oil settle. Avoid overfilling.
- Use the sight glass (or dipstick if equipped) to verify oil level. The oil should fall between the minimum and maximum marks with the bike level.
-
Reinstall Oil Filler Cap
Replace the oil fill cap securely. Use a pair of pliers for a slight snug if needed (per KTM's recommendations), but do not overtighten. -
Final Check and Cleanup
- Start the engine and let it idle for 1-2 minutes. Check for leaks around the drain plug, oil filter area, and cap.
- Turn off the bike and re-inspect oil level, adding a small amount if necessary.
- Dispose of used oil and filters responsibly according to local regulations.
Model-Specific Tips for the 2000 KTM 250 EXC
- Oil Change Interval: For most trail riders, every 20 hours of ride time or after every few intense rides is recommended.
- Oil Quantity: Never exceed 0.8 liters; check your owner's manual if uncertain.
- Screen Cleaning: Cleaning the mesh screens during every oil change is essential for this year and model; failing to do so can hinder oil flow and endanger your engine.
- Drain Plug Location: Unlike some bikes, the 2000 250 EXC has both a main plug and an oil screen plug—be sure to service both.
- Torque Spec: 20 Nm is precise—too much force can strip the soft aluminum threads in the crankcase.
- Oil Type: Use high quality, motorcycle-specific fully synthetic oil, ideally Motorex 15W50, as recommended by KTM.
Conclusion
Following this robust, step-by-step process will help maintain your 2000 KTM 250 EXC in peak condition. Regular oil changes, component inspections, and attention to manufacturer recommendations will keep your bike running strong for years to come.
