Model-Specific Call-Outs for the 2024 Sherco 250 SEF FACTORY

  • Engine capacity: 1 liter of SAE 5W-40 is required. Overflowing or underfilling can harm the engine.
    Do not substitute oil weight as the engine is designed for SAE 5W-40.
  • Magnetic drain plugs are present; ensure they are cleaned during every oil change to remove metallic debris.
  • Replace all crush washers and O-rings with new ones every change–reusing them can cause leaks.
  • Oil change interval: Refer to your owner—s manual and riding conditions but consider around every 10–15 hours of riding. Although the manual may suggest longer intervals, more frequent changes prolong engine life.

Step-by-Step Instructions

  1. Preparation
    • Warm the engine briefly–about 2–3 minutes. This thins the oil and ensures old oil drains fully. Turn the engine off.
    • Carefully position your bike upright using a stand for stability.
    • Place your drain pan under the bottom of the engine to catch the draining oil.
  2. Removing Old Oil
    • Using a 17mm socket, remove the main oil drain plug and allow all oil to drain. Inspect the magnetic tip for metal debris. Thoroughly clean the plug.
    • Locate and remove the secondary drain bolt (if present on your specific model) to ensure all oil is expelled. Both bolts have crush washers; discard old washers.
  3. Changing the Oil Filter
    • Use a 4mm Allen key to carefully unbolt and remove the oil filter cover. Be mindful of the orientation and O-ring behind the cover.
    • Take out the old oil filter and discard it.
    • Lightly lubricate the new filter’s gasket with fresh oil. Insert the new filter with the gasket facing the engine.
    • Reinstall the filter cover with a new O-ring, torquing the bolts to the manual's specified 10–15 Nm (7–11 ft-lb). Do not over-tighten.
  4. Inspect and Clean the Pre-Filter (Strainer)
    • Remove the pre-filter cover with an 8mm socket.
    • Pull out the metal oil strainer and inspect it for debris. Clean thoroughly if reusable or replace if necessary.
    • Reinstall with a new O-ring or seal as required.
  5. Reinstall Drained Components
    • Install the drain bolt(s) with new crush washers, torquing to 15–25 Nm (11–18 ft-lb) per your manual.
    • Double-check all fittings for security and potential leaks.
  6. Add New Oil
    • Remove the engine oil fill plug (usually right side of the engine).
    • Pour in 1 liter of SAE 5W-40 oil. This is critical as overfilling or underfilling can damage internal components.
    • Reinstall the fill plug.
  7. Check for Leaks and Level
    • Start the engine and allow it to idle for 1 minute; then shut off and let it rest for a couple of minutes.
    • Inspect around the drain plug and filter for leaks. Tighten if needed.
    • Check oil level in the sight window with bike upright; add oil if necessary to reach correct mark. Do not overfill.
  8. Dispose of Used Oil Properly
    • Recycle all used oil and filters at a certified recycling facility. Never dump oil in the trash or on the ground.

Tips and Warnings

  • Always use fresh washers and O-rings to avoid leaks.
  • Never run the engine with low or no oil—severe damage can occur almost instantly.
  • The 2024 250 SEF FACTORY engine is equipped with a dry-sump style lubrication with two oil pumps. Complete draining and filter replacement during every change is vital for system integrity.
  • If you notice excess metallic debris on the magnetic drain plug or in the oil, consult a professional mechanic before riding further.

Final Thoughts

  • Routine oil changes are the most effective way to protect the high-compression racing engine of your Sherco 250 SEF FACTORY. Stick to quality oil, OEM filters, clean your drain plugs, and strictly follow torque specs on every fastener for best results.
