Special Call-Outs for the 2004 Husaberg FC450
- The oil fill capacity is 1 liter.
- Always use a fully synthetic oil formulated for high-performance off-road motorcycles.
- The oil filter cover features O-rings that should be checked for damage and greased on reassembly.
- Torque specs are critical: Tighten oil filter cover screws to 6 Nm–do not overtighten.
- After an oil change, always start the motorcycle and check for leaks at the filter cover and drain bolt.
Step-by-Step Oil Change Instructions
- Warm up your engine by running your bike for several minutes. This helps the oil flow freely and brings any contaminants into suspension for removal.
- Place the motorcycle upright and secure it. Position your catch pan under the oil drain bolt.
- Remove the oil drain bolt (and skid plate if needed). Allow oil to completely drain into the catch pan. Inspect the old crush washer and replace if necessary.
-
Remove the oil filter cover:
- Remove both screws from the filter cover.
- Screw an M6 screw into the center hole–only hand-tighten to avoid damage.
- Gently pull the oil filter cover off using the screw as a handle.
- Remove the M6 screw from the cover.
-
Extract the old oil filter using pliers.
Tip: Take note of the filter orientation for correct insertion of the new one. - Clean the oil filter housing and cover. Wipe all mating and sealing surfaces. Examine the cover's O-rings for damage and replace if needed. Grease O-rings lightly before reassembly.
- With the bike on its side, fill the oil filter housing halfway with engine oil (this helps prime the filter and reduces dry starts). Insert the new oil filter.
- Reinstall the oil filter cover. Replace the screws and torque them to 6 Nm.
- Return the bike to an upright position.
- Install a new or cleaned drain plug/crush washer and tighten to manufacturer's specification.
- Remove the oil filler plug and add 1 liter of fully synthetic 4T oil.
- Reinstall the oil filler cap.
- Start the motorcycle and let it idle for several minutes. This circulates oil through the filter and passages. Check for leaks at the drain bolt and oil filter cover.
- Turn off the bike and allow the oil to settle for a few minutes. Check the oil level and top off if necessary.
Extra Tips & Maintenance Notes
- If you've installed a Votex oil drain valve, simply attach the draining hose, open the valve, and drain oil directly into your pan. This minimizes mess and speeds up the process.
- Dispose of old oil and the filter at a certified recycling center.
- Inspect engine mounting and frame for any signs of leaks after operation.
