Step-by-Step Instructions
-
Warm up the engine
Start your 2013 KTM 65SX and let it idle for a few minutes. This helps the oil become less viscous, ensuring a more complete drain.
Caution: The oil and engine parts may become hot. Use gloves and care when working on the bike. -
Secure the bike
Turn off the engine and place the bike upright on a stand. Make sure it is stable before proceeding.
-
Remove the oil fill cap
This allows air in and helps the oil drain freely.
The oil fill cap is typically located at the top of the crankcase, right side of the engine. -
Locate the drain bolt and place the catch pan
The drain plug is on the left side of the engine, behind the shifter – use a 13mm socket or wrench to loosen it. Put your drain pan in place to capture old oil.
The drain plug may be hard to spot the first time, but it's tucked behind the shift lever assembly. -
Remove the drain plug
Carefully loosen and remove the drain bolt. Allow the oil to drain completely. Tip the bike gently to one side to encourage all the oil out if needed.
Replace the crush washer or O-ring on the drain plug at this time if necessary, as leaks often begin with worn seals. -
Inspect and clean the drain plug
The 2013 KTM 65SX uses a magnetic drain plug. Check for any metallic debris collected on the tip—it’s normal to find some fine metal filings in a 2-stroke gearbox. Clean with a rag before reinstalling.
Replace the O-ring if it appears cracked or worn. -
Reinstall the drain bolt
Hand-tighten the bolt first, then snug it down with your wrench or preferably a torque wrench set to the correct spec. Over-tightening can damage threads or the case. For most KTM 65SX models, tighten to 20 Nm (14.8 ft-lbs) if using a torque wrench.
-
Add the correct oil
Pour in 300 ml of fresh gear oil using the funnel to prevent spills. Pour slowly and do not overfill.
Double-check the oil type recommended by your KTM owner’s manual. -
Replace the oil fill cap
Wipe any spilled oil around the fill opening and re-install the cap securely.
-
Check for leaks and clean up
Start the engine and let it idle while checking for leaks at the drain bolt. Inspect the area under the bike and wipe any drips. Shut off the engine, wait a minute, then check the oil level with the sight glass (if equipped) or dipstick as needed and top off if required.
Model-Specific Call-Outs for 2013 KTM 65SX
- Drain Plug Location: Uniquely, the 2013 KTM 65SX drain plug is located behind the shift lever; older or different bikes may have it in another spot. Always confirm location before starting.
- Oil Volume: This model takes exactly 300 ml of gear oil, not engine oil. Overfilling can damage seals; underfilling can result in rough shifting and gear wear.
- Crush Washer or O-ring: Replace every change to avoid leaks. Universal O-ring kits work, but the best fit will be OEM KTM parts.
- Magnetic Drain Plug: Check for debris each time. Some fine metal shavings are normal, but large chips can signal internal gearbox issues.
- Recommended Oil: Use oil specified in your owner’s manual for the 2013 KTM 65SX—consult it for viscosity and compatibility, especially for racing conditions or heavy use.
Pro Tips
- Warm up thoroughly for the best drain results.
- Careful with the drain plug threads—never over-tighten. Use a torque wrench if available.
- Take your time: Patience ensures you won’t spill or miss a step.
- Set a reminder for the next oil change. For racing or hard use, change more frequently.
