Step-by-Step Oil Change Procedure
-
Warm up the Engine
Start your ES 500F and let it idle for 3–5 minutes in a well-ventilated space. Warming the oil helps it drain completely. -
Remove the Skid Plate (if equipped)
Use the appropriate socket/Allen to remove the skid plate, allowing easy access to the drain bolts. -
Clean Around the Drain Area
Use a clean rag and contact cleaner to remove dirt and debris, preventing contamination as you open the case. -
Position the Drain Pan
Place the drain pan directly under the main drain bolt. -
Remove Oil Drain Bolts and Screens
Unscrew the main drain bolt (13mm or as specified). Allow oil to flow completely.
Remove both oil screens with the appropriate tools (snap ring/pliers may be needed). This is important, as debris can collect here.
Remove the oil filter cover bolts (usually 8mm or 10mm), then pull out the used oil filter. -
Inspect and Clean Components
Wipe drain bolt and clean or replace the crush washer. Clean oil screens with brake cleaner/contact cleaner and inspect for debris. If metal shards are present, note or photograph, as this may indicate internal wear. -
Install New Filter and Reassemble
Lightly oil the new OEM filter, then insert into the case (ensure proper alignment). Replace the oil filter cover and torque bolts to manufacturer spec.
Reinstall cleaned oil screens.
Thread in the drain bolt with the new crush washer and tighten to specified torque. -
Add Fresh Oil
Remove the oil filler cap. Pour in 1.2L of 10W/50 full synthetic oil using your measuring cup and funnel.
Reinstall the filler cap. -
Check Oil Level and For Leaks
Run the engine for 1–2 minutes, then turn off and let sit for a minute. With the bike upright, check the sight glass or dipstick (if equipped) for correct oil level.
Inspect around the drain plug and filter for leaks. If any are found, shut off and address immediately. -
Reinstall Skid Plate
Once satisfied, reattach the skid plate. -
Dispose of Old Oil Responsibly
Pour used oil into a sealed container and take it to a local recycling center or auto parts store that accepts motor oil.
ES 500F-Specific Tips
- Always use a new OEM crush washer for the drain bolt to prevent leaks.
- Check for two oil screens: one on the engine’s left lower side and one in the front lower area–both must be cleaned at every oil change.
- Inspect the magnetic drain plug for metal shavings–small amounts are normal, but excessive debris can indicate engine issues.
- If you’ve added any aftermarket engine protection or larger skid plates, removal may require extra steps or different tools.
Torque Specs and Capacity
- Drain Plug: 10 Nm (always verify in the owner's manual for changes)
- Oil Filter Cover Bolts: 8 Nm
- Oil Capacity: 1.2 liters (when replacing filter)
Notes and Cautions
- Never use non-synthetic or non-motorcycle-specific oil, as it may harm clutch and engine components.
- Tighten bolts to spec–do not overtighten, to avoid stripping threads in soft aluminum cases.
- Keep a close service interval, especially after hard racing or dusty rides. This will greatly increase your ES 500F’s lifespan.
- If you encounter oil leaks or engine warning lights after your service, discontinue use and consult your dealer or MotoSport.com for further troubleshooting.
