Shop parts for a 2010 Suzuki RM85 Dirt Bike.
Keeping the air filter of your 2010 Suzuki RM85 clean and properly maintained is essential for optimal engine performance and longevity. The RM85 uses a foam air filter designed to trap dirt and debris before it reaches the engine, but its efficiency depends on routine cleaning and replacement. Here's MotoSport's proprietary guide tailored to your bike.
Why Your RM85's Filter Needs Attention
The RM85's high-revving two-stroke engine is highly sensitive to air flow restrictions – a dirty filter can impact performance, increase wear, and even cause engine damage. Regular maintenance ensures reliable starts and strong low-end power, characteristics prized in the RM85's competitive class.
Tools & Supplies Needed
- Non-flammable cleaning solvent (e.g. foam filter cleaner)
- Foam filter oil
- Grease (for sealing)
- Clean towels or shop rags
- Nitrile gloves (recommended)
- Replacement air filter (if needed)
Step-by-Step Cleaning & Replacement Instructions
- Remove the seat by loosening the seat fasteners with the appropriate wrench or socket.
-
Remove the air cleaner cap to access the air filter assembly.
Tip: Take care not to let dirt fall into the intake when removing the seat or filter. - Detach the air filter by unscrewing and gently pulling it away from the filter cage.
- Inspect the filter – replace if damaged, torn, cracked, or excessively worn.
- Cleaning: Immerse the foam element in a pan with a non-flammable filter cleaner. Squeeze (do not twist or wring) to release dirt and old oil. Repeat until clean.
- Dry completely. Use a clean towel; air dry if possible.
- Oil the Filter: Pour filter oil into a clean plastic bag, add the element, and work the oil in thoroughly. Squeeze out excess oil.
- Apply a thin layer of grease along the filter's sealing edge for added protection against dust leakage. This is especially important for the RM85, whose compact airbox can accumulate fine debris during hard riding.
- Reinstall Filter & Components: Ensure holes on the filter and cage are aligned. Secure tightly without overtightening.
- Reattach air cleaner cover and seat.
Replacement Tips Unique to RM85 (2010)
- The RM85 filter is compact and vulnerable to dirt infiltration after repeated washing. Inspect the foam for fine cracks and hard spots - replace if found.
- Use only recommended foam filter oil to prevent airflow restriction and preserve foam flexibility.
- The sealing rim of the filter should always be greased, since the RM85's airbox design has less margin for error.
- Replace the filter after prolonged heavy racing, excessive mud riding, or whenever filter damage is suspected.
- Inspect the intake tract for debris before installing the cleaned (or new) filter and cap.
Quick Reference Maintenance Intervals
- Clean after every ride in dusty or wet conditions.
- Clean/re-oil after every 2–3 rides in average conditions.
- Replace with a new filter at least once each season, or more often if damaged or heavily worn.
Note for RM85 Owners
