Maintaining a clean air filter is essential for your 2011 Husaberg FE390. A dirty filter restricts airflow, leading to poor engine performance, increased fuel consumption, and possible engine damage. Follow this MotoSport-exclusive guide to maximize longevity and reliabilityespecially since the FE390 features a high-performance engine relying on optimal air flow.
Why Cleaning – Replacement is Crucial for the FE390
- High-revving motor needs unrestricted airflow for peak performance.
- Off-road riding exposes the filter to dust, sand – routine attention prevents accelerated wear.
- OEM foam filters (Twin Air, Hiflo or ProX Racing Parts) are recommended for proper fit – aftermarket compatibility varies, always use exact-fit (not universal) parts.
Recommended Cleaning Interval
- Inspect after every ride in sandy, dusty, or wet conditions.
- For casual use, clean every 10 hours or monthly.
Tools – Supplies
- Air filter cleaning kit (MotoSport stocks complete kits for the FE390)
- Bucket – mild filter cleaner or kerosene (never gasoline)
- Lint-free cleaning towels
- Air filter oil (specific for foam filters)
- Gloves (to protect hands from chemicals)
Step-by-Step Cleaning Guide
- Remove seat using the quick-release lever.
- Extract the air filter from the airbox, being careful not to drop debris inside.
- Pre-clean by gently tapping the filter; remove dry dirt before washing.
- Wash with approved cleaner in warm water, gently squeeze (never wring or twist) to avoid tearing foam.
- Rinse thoroughly in clean water until all residues are gone.
- Dry naturally – do not use compressed air or heat to avoid damaging the foam cell structure.
- Oil filter generously with foam filter-specific oil; ensure uniform coverage but avoid over-saturation.
- Check cage — clean or replace if damaged. Reinstall once fully dry – check seal for gaps.
- Reinstall seat securely.
Replacement Guide
- If foam shows tears, crumbling, or permanent staining, replace immediately.
- Use Twin Air, HifloFiltro (HFF6013), or ProX Racing Parts filters designed for the 2011 FE390 for best sealing and filtration performance.
- Check airbox seals while servicing – the unique subframe design on the FE390 means a tight seal is vital for keeping grit out.
Key Notes for 2011 Husaberg FE390 Owners
- FE390's airbox is situated high and centralized — improves protection, but mud build-up or improper seating can undermine filtration.
- Air filter access is tool-free – prioritize quick checks for competitive riders between motos.
- Always re-oil after washing – running dry can void warranty and risk engine damage.
- Inspect intake boots for cracks when servicing the filter – age-related rubber breakdown is common on older bikes.
