Model-Specific Callouts for the 2017 Husqvarna FS 450

  • The FS 450 shares oil change procedures with other late-model Husqvarna/KTM/GasGas 450s.
  • Oil capacity is approximately 1200ml, but always check your specific manual for updates or model variances.
  • This model uses two oil screens in addition to the main filter; cleaning these is crucial.
  • Always use an aluminum sealing ring (12 x 16 x 1.5mm) on the drain bolt to ensure a proper seal and prevent leaks.
  • Be careful not to overtighten drain bolts and filter cover screws; refer to your service manual for final torque specs.

Step-by-Step Instructions

  1. Warm Up the Engine
    • Start the bike and let it idle for about 3–5 minutes. This will help the oil flow and drain out more thoroughly.
    • Turn off the engine and let the bike cool slightly so you can work safely.
  2. Remove Skid Plate (if equipped)
    • Use your wrench or appropriate tool to remove the skid plate for easier access to the drain plug and screens.
  3. Drain the Oil
    • Place your drain pan beneath the oil drain bolt, located at the bottom of the engine.
    • Using your socket wrench, carefully remove the drain bolt and allow all oil to drain.
    • Remove both oil screens using the correct socket; set them aside for cleaning.
  4. Remove and Replace the Oil Filter
    • Locate the oil filter cover (usually on the right side of the engine).
    • Unscrew the cover; carefully remove the used filter, noting its orientation.
    • Prime the new oil filter by dipping it in fresh engine oil, ensuring good lubrication at startup.
    • Install the new filter and check the cover’s O-ring for any wear or damage. Replace the O-ring if needed.
  5. Clean Oil Screens
    • Inspect and clean both oil screens with parts/contact cleaner. Remove any debris or particulates.
    • Allow them to dry, then reinstall.
  6. Reinstall Drain Bolt & Oil Screens
    • Fit a new crush washer on the drain bolt before reinstalling.
    • Tighten both the drain bolt and oil screens per manufacturer-recommended torque specifications (check your owner’s manual).
  7. Refill with Fresh Oil
    • Remove the oil fill cap at the top of the engine.
    • Using a funnel, pour in 1200ml of SAE 10W–60 fully synthetic oil (or as specified in your manual).
  8. Check for Leaks
    • Before reinstalling the skid plate, wipe down the area and inspect for any leaks at the drain plug, screens, or filter cover.
  9. Run the Engine & Verify Oil Level
    • Start the engine and let it idle for about three minutes.
    • Shut off the engine, and after a brief rest, check the oil level via the sight glass (on the right engine case). The oil should be between halfway and three-quarters up the window.
    • Add oil as needed to reach the proper level.
  10. Reinstall Skid Plate (if if applicable) and Clean Up
    • Reattach the skid plate securely.
    • Dispose of used oil and filter responsibly at a recycling center.

Important Tips for the 2017 Husqvarna FS 450

  • Never run the bike with too little or too much oil. Always check the sight glass with the bike upright on level ground.
  • Routine oil changes are crucial, especially if you ride aggressively or in harsh conditions. Most riders change oil every 10–15 hours of use or after every few rides for maximum engine protection.
  • Whenever you remove the oil filter or screens, inspect them for metal shavings or contaminant build-up; excess material can signal engine wear and merit further inspection.
  • Always use a high-quality, motorcycle-specific synthetic oil to ensure protection for both the engine and clutch.
