This guide is proprietary to MotoSport.com and details every step needed to change the oil on a 2020 Husqvarna FC350. We'll cover the tools required, step-by-step procedures, and specific notes applicable to this model.

Tools and Supplies Required

  • Triangle stand or center bike stand
  • Drain pan to catch used oil
  • Socket wrench set (13mm deep socket, 8mm socket, 1/2” wrench)
  • Needle nose pliers
  • Paper towels and shop rags
  • New oil filter (OEM recommended)
  • Replacement engine oil (SAE 10W-50 full synthetic is recommended)
  • Measuring cup or graduated cylinder (recommended for accuracy)
  • Clean funnel (optional, but helpful)
  • New crush washers (as needed)

Before You Begin: Model-Specific Call-Outs

  • The 2020 Husqvarna FC350 oil capacity is 1.1 quarts (1.0 liter).
  • Use SAE 10W-50 full synthetic oil for best performance and protection.
  • This bike uses both an oil filter and an oil screen—both must be addressed during the change process.
  • Consult your owner’s manual for torque specs on drain bolts and covers. Always use proper torque to avoid stripping threads or leaks.
  • Changing oil every 10–15 hours or after every race is highly recommended for optimal engine longevity.

Step-by-Step: Changing the Oil

  1. Warm Up the Engine
    • Start and run the bike for 1–2 minutes. This warms the oil, helping it drain more completely.
  2. Stabilize the Motorcycle
    • Place your FC350 on a triangle or center stand to keep it upright and stable during oil draining.
  3. Drain the Engine Oil
    • Place a drain pan under the bike’s bottom end. Use a 13mm deep socket or 1/2” wrench to remove the main drain bolt on the engine case.
    • Allow all oil to drain completely.
  4. Remove and Clean the Oil Screen
    • Locate the oil screen bolt (often on the right lower engine case). Remove it using the appropriate wrench. Carefully extract the screen using needle nose pliers.
    • Inspect and clean the screen with brake or contact cleaner and a shop towel. Remove any metal particles or debris.
  5. Remove the Oil Filter
    • With an 8mm socket, remove the bolts securing the oil filter cover.
    • Pull out the old oil filter. If oil drains from this area, allow it to finish draining.
  6. Reinstall Oil Screen and Drain Bolts
    • Thoroughly clean and dry the bolts and screen before reinstallation.
    • Install new crush washers if needed. Reinsert and tighten the oil screen and main drain bolt to factory torque spec.
  7. Install New Oil Filter
    • Lightly oil the new filter with fresh engine oil. Insert it into the oil filter housing, ensuring correct orientation and that it “clicks” into place.
    • Replace the cover and tighten to torque spec. Make sure the area is clean and free of debris or excess oil.
  8. Add New Engine Oil
    • Set the bike upright and level.
    • Using a funnel and measuring cup, pour in 1.1 quarts (1.0 liter) of SAE 10W-50 full synthetic oil.
    • Reinstall the oil fill cap.
  9. Check Oil Level
    • Start the motorcycle and let it idle for a minute, then shut off and wait a few minutes for the oil to settle.
    • With the bike standing straight, check the oil level through the sight glass (if equipped) or via the dipstick. Oil should be centered in the window or at the “full” mark when cold.
    • Add oil as needed, but do not overfill.
  10. Final Checks
    • Inspect all bolts and spouts for leaks.
    • Wipe off any spilled oil and ensure bike is clean and ready to ride.

Special Notes for 2020 Husqvarna FC350 Owners

  • Always refer to your owner’s manual for torque specs and recommended oil brands.
  • Replace the oil filter and screen every oil change for maximum engine health.
  • Always use full synthetic 10W-50 oil for high-performance four-stroke engines.
  • This procedure is nearly identical for KTM and GasGas 350 models, but confirm capacities and filter type.
  • If riding in extreme heat, muddy, or sandy conditions, shorten your oil change interval.

Conclusion

Changing the oil in your 2020 Husqvarna FC350 is straightforward and vital for peak performance. Always use manufacturer-recommended parts and lubricants, pay close attention to each step and, when in doubt, refer to professional resources or your owner’s manual for guidance. Performing regular oil changes ensures your FC350 remains reliable and race-ready ride after ride.
