Changing the oil in your 2020 Sherco 500 SEF FACTORY is vital for maintaining peak engine performance and longevity. This guide from MotoSport.com will walk you step by step through the process, identify the exact tools and supplies needed, and call out specific details all owners of this model should know.

Tools and Supplies Needed

  • Socket wrench set
  • Drain pan
  • Funnel
  • Clean rags
  • Replacement crush washers (recommended)
  • Oil filter: HIFLO FILTRO HF611 or equivalent
  • Fully synthetic 4-stroke motorcycle oil: 10W-50 or 10W-60 (Motul 7100 10W-60 recommended for performance)
  • Gloves and eye protection
  • Torque wrench (for precise tightening–target bolt specs outlined below)
  • Degreaser (optional, for cleaning parts)

Model-Specific Call-Outs for Sherco 500 SEF FACTORY (2020)

  • This model uses a dual-drain-bolt system. There is a main drain bolt (with magnetic tip) and two additional bolts that secure internal oil screens—both need to be removed to properly drain old oil and clean the system.
  • The oil filter cover is located on the right side of the engine. Take care not to lose the O-ring when removing this cover.
  • Recommended oil capacity is around 1.2 liters, but always check your owner's manual for exact specifications and use the inspection window or dipstick to verify the correct level after refilling.
  • Tighten all bolts using manufacturer-specified torque values (usually 10 Nm on smaller screws/bolts around the oil filter and case) to prevent stripping or leaks.

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    • Start your Sherco and let it idle for about 2–3 minutes. This thins the oil slightly, helping it drain completely.
  2. Place Bike Securely on Stand
    • Turn off the engine and allow it to cool for a few minutes. Position the bike upright and level on a sturdy stand or lift.
  3. Remove the Skid Plate (if equipped)
    • This makes access to the drain bolts easier and reduces mess.
  4. Loosen the Oil Fill Cap
    • Loosen or remove the fill cap on the right side to allow air in and oil to drain smoothly.
  5. Drain the Oil
    • Position your drain pan beneath the engine.
    • Remove the main oil drain bolt (magnetic) underneath the engine. Let the oil drain completely.
    • While draining, carefully clean the bolt and inspect for any metal shavings on the magnet, which can indicate excessive wear.
    • Remove the two additional bolts that hold the internal oil screens. Pull out and clean both metal screens thoroughly. Use degreaser if needed, dry completely before reinstalling.
  6. Replace and Tighten Drain Bolts
    • Once all oil and residue are removed, reinstall the oil screens (ensure correct orientation), replace crush washers if worn, and reinstall all three bolts. Tighten to 10 Nm (factory spec) using your torque wrench.
  7. Remove and Replace the Oil Filter
    • Locate the oil filter cover and remove the screws. Remove the old filter and O-ring.
    • Lubricate the new oil filter gaskets and the O-ring with fresh oil.
    • Prime the filter by pouring a small amount of fresh oil inside the filter (optional, but ensures quick oil flow on restart).
    • Install the new filter and O-ring. Reattach the oil filter cover and tighten screws (do not overtighten).
  8. Refill with Fresh Oil
    • Slowly pour 1.2 liters of fully synthetic 10W-50 or 10W-60 oil using a funnel. Pour in increments and check the level as you fill.
    • Replace the oil fill cap.
  9. Check Oil Level
    • Ensure the bike is upright. Use the inspection window (should appear about two-thirds full). If it's low, add oil in small amounts as needed.
  10. Start the Engine and Recheck
    • Start the engine and run it for 2–3 minutes. This circulates the oil.
    • Shut off the engine and wait 2 minutes for the oil to settle. Recheck the level and top off if necessary.
  11. Final Checks
    • Inspect for leaks around all drain bolts and the filter cover. Take a short ride, allow the bike to cool, and check again.
    • Safely dispose of your used oil and filter at a recycling center or auto parts store.

Pro Tips for the 2020 Sherco 500 SEF FACTORY Owner

  • Always use fully synthetic oil designed for 4-stroke motorcycles, ideally with a 10W-60 viscosity for heavy-duty use.
  • Inspect both the magnetic drain plug and internal oil screens for debris every change; excessive shavings could indicate deeper engine issues.
  • Stick to maintenance intervals recommended by the manufacturer or more frequently if riding in extreme conditions.
  • Keep spare oil filter covers' O-ring and crush washers on hand to ensure proper sealing with every oil change.
