Shop parts for a 2024 Sherco 300 SEF FACTORY Dirt Bike.

Keeping your 2024 Sherco 300 SEF Factory running at its best means regular maintenance, and changing the engine oil is one of the most crucial tasks. This detailed guide, proprietary to MotoSport.com, walks you through everything you need, every step, and model-specific tips for a successful, clean oil change.

Tools and Materials Needed

  • 17mm socket (for drain bolt)
  • 8mm socket (for filter cover bolts)
  • 4mm Allen wrench (for pre-filter)
  • Torque wrench (to retighten to spec)
  • Drain pan (minimum 2-liter capacity)
  • Shop rags or paper towels
  • New oil filter (replace every change)
  • New crush washers (required for drain bolts)
  • 1 liter of SAE 5W40 motorcycle oil (high quality synthetic recommended)
  • Funnel (optional, but helpful)
  • Latex or nitrile gloves (recommended)

Step-by-Step Instructions

  1. Warm Up the Engine
    Run your Sherco 300 SEF Factory for about 3-5 minutes to warm up the oil. Warm oil drains more completely and carries contaminants out with it.
  2. Prepare Your Workspace
    Turn off the engine and set the bike upright on a stable stand. Make sure your work area is well-ventilated and avoid working on grass or dirt to prevent contamination.
  3. Remove the Skid Plate (If Equipped)
    If your bike has a skid plate, remove it to access the drain bolts easily.
  4. Locate and Remove Drain Bolts
    The 2024 Sherco 300 SEF Factory has two oil drain bolts underneath the engine. Place the drain pan under both. Using a 17mm socket, unscrew both bolts carefully and allow the oil to drain completely.
    Note: Each drain bolt uses a crush washer. Always replace them to ensure a proper seal and prevent leaks. Be cautious of the magnetic drain plug; clean it thoroughly as it collects metal particles.
  5. Remove the Oil Filter Cover
    Use the 8mm socket to remove the bolts securing the oil filter cover on the right side of the engine. Pull off the cover, then carefully extract the old oil filter.
  6. Replace the Oil Filter
    • Lubricate the rubber sealing ring of the new oil filter with a dab of clean engine oil.
    • Install the filter, making sure it seats correctly, with the sealing ring facing the engine case.
    • Replace the oil filter cover with a new O-ring or gasket as needed; torque the bolts to 8-10 Nm (spec check: 8mm cover bolts, do not overtighten).
    Sherco factory recommendation: always replace the filter at every oil change for maximum protection.
  7. Inspect and Clean the Pre-Filter
    Use a 4mm Allen wrench to remove the pre-filter (screen). Clean it thoroughly with fresh solvent and dry it before reinstalling.
  8. Reinstall Drain Plugs and Pre-Filter
    Ensure both drain bolts have new crush washers. Torque the bolts to 15 Nm as specified by Sherco.
    Reinsert the cleaned pre-filter and secure it.
  9. Add New Engine Oil
    Open the oil fill cap (right side, top of crankcase). Use a funnel, pour in 1 liter of SAE 5W40 premium motorcycle oil (Sherco recommends high-quality full-synthetic).
    Tip: Pour slowly and allow oil to settle to avoid overfilling.
  10. Check Oil Level
    Stand the bike vertical and inspect the sight glass or dipstick (see manual page 27). Level should be between the upper and lower marks. Top off if needed, little by little.
    Important: Do not overfill, as this can cause foaming, leaks, and engine problems.
  11. Start the Engine and Inspect for Leaks
    Start the engine and run for 1-2 minutes to circulate new oil. Turn it off and let it sit a minute, then re-check oil level and inspect around the drain plugs, filter cover, and pre-filter for any signs of fresh oil leaks. Tighten as needed (always to spec).
  12. Dispose of Old Oil Properly
    Pour the used oil into a sealed container and take it, plus the old filter, to a certified recycling or hazardous waste facility. Never pour engine oil down a drain or into nature.

Critical 2024 Sherco 300 SEF FACTORY Model-Specific Call-Outs

  • Oil Quantity: Always add exactly 1L of oil as per Sherco's official specification for the 2024 300 SEF Factory.
    Overfilling may lead to engine issues; underfilling risks inadequate lubrication.
  • Oil Specification: Use only SAE 5W40 motorcycle-specific oil for best clutch and engine performance. Older recommendations varied, but for 2024 this is official.
  • Drain Bolt Torque: Factory torque for drain bolts is 15Nm. Using a torque wrench minimizes risk of thread damage or leaks.
  • No Impact Tools: Never use an impact wrench on engine case fasteners or drain bolts. Hand tools only for safety.
  • Frequency: Sherco recommends a minimum oil change interval of every 50 hours or at least every season. More frequent changes are beneficial for racing, hard enduro, or dusty conditions.
  • Magnetic Plug: The magnetic drain plug should always be cleaned thoroughly at each oil change. Metal filings are a warning sign of excessive wear and should be monitored by Sherco or a professional mechanic if excessive.
  • Filter Replacement: Always replace the filter and O-rings on every change. Pre-filter (screen) must be cleaned every time. Not doing so risks oil starvation and engine damage.

Final Checks and MotoSport Pro Tip

  • After your first ride, re-check for leaks and top off the oil if needed.
  • Inspect the oil after each ride for unexpected darkening or contaminants, which could indicate engine problems.
  • MotoSport.com carries all Sherco-compatible filters, O-rings, oil, and tools for your 2024 300 SEF Factory. Using the right parts ensures warranty compliance and longevity.
