Changing the oil in your 2023 Sherco 250 SEF FACTORY is one of the most important maintenance tasks to keep your dirt bike running smoothly and reliably. This guide from MotoSport.com will walk you through the process step by step, including all tools required and highlighting important tips specific to this model.

Tools and Materials Needed

  • 8mm socket
  • 17mm socket
  • 4mm Allen wrench
  • Oil catch pan/container
  • Replacement oil filter (replace at every oil change)
  • New O-ring for the oil filter cap
  • New crush washers/gaskets for drain plugs
  • SAE 10W60 motor oil (0.9 liters)
  • Clean rags or shop towels
  • Torque wrench (for precise tightening)

Important Callouts Before You Start

  • This bike uses two separate drain plugs and a pre-filter screen.
  • Always replace the oil filter and use new crush washers for the drain bolts to prevent leaks.
  • Never use power tools when tightening—hand tools and a torque wrench will prevent over-tightening and stripping.
  • Dispose of oil and used filters responsibly at a proper collection center.
  • Use only the recommended SAE 10W60 oil for optimal performance and longevity.

Step-by-Step Oil Change Process

  1. Warm Up the Engine
    • Start the bike and let it idle for 2–3 minutes. This helps the oil flow out more easily by decreasing viscosity.
    • Shut off the engine and place the bike securely on a stand.
  2. Remove the Engine Guard (if installed)
    • Use the appropriate tools to remove the skid plate or engine guard for easier access to drains and filter.
  3. Drain the Oil
    • Place your oil catch pan beneath the engine.
    • Locate the main drain plug (M19, 22Nm) and the magnetic drain plug (M12, 15Nm).
    • Remove both plugs using the correct sockets. Allow oil to fully drain.
    • Remove the pre-filter screen and let it drain; clean it with a lint-free rag.
  4. Remove and Replace the Oil Filter
    • Take off the oil filter cap with a 4mm Allen wrench.
    • Remove the old oil filter and install the new one, ensuring orientation matches the manual diagram. Use a new O-ring for the cap.
    • Reinstall the oil filter cap and torque to 15Nm.
  5. Reinstall Drain Plugs and Pre-filter
    • Reinstall the pre-filter, main drain plug, and magnetic drain plug using new crush washers/gaskets.
    • Tighten to manufacturer specs: Main drain plug 22Nm, Magnetic plug 15Nm.
  6. Refill with Fresh Oil
    • Remove the oil filler cap.
    • Pour in 0.9 liters of SAE 10W60 oil.
    • Replace the filler cap securely.
  7. Check Oil Level
    • Let the bike sit for a minute, then check the sight glass or dipstick. Top off if necessary, but do not overfill.
    • Start the engine for 30 seconds, turn off, and re-check the level after a minute—top off as needed.
  8. Reinstall Skid Plate/Engine Guard
    • If you removed it, reinstall using the proper hardware.
  9. Dispose of Oil Responsibly
    • Take old oil and used filters to a recycling center. Never pour oil down drains or into the environment.

Specific Tips for the 2023 Sherco 250 SEF FACTORY

  • Use the correct torque values: overtightening drain plugs or filter caps can crack engine cases or strip threads.
  • This model’s oil system requires draining from both plugs and cleaning the pre-filter screen each time.
  • Always double-check the orientation of the new oil filter; installing it backwards can cause engine damage.
  • If your bike has aftermarket parts (like a skid plate with limited access), you may need to remove these during the process.

Recommended Service Intervals

  • Many riders change oil every 10–20 hours of use for hard riding, even though Sherco recommends longer intervals. Fresh oil is cheap insurance.

Final Inspection and Test

  • Check for leaks around plugs and the oil filter area. Address any leakage immediately—usually a sign of worn O-rings or over-/under-torque.
  • Go for a short ride, let the motor fully heat up, then re-check the oil level. Top off if necessary.
