Proper air filter maintenance on your 2011 Suzuki RM85 is crucial for maximizing engine performance and longevity. The RM85's two-stroke motor is especially sensitive to air intake conditions, so regular filter cleaning and timely replacement are essential. This guide from MotoSport covers step-by-step air filter service for your bike – including expert tips unique to the 2011 RM85.
When to Clean or Replace Your Air Filter
- Clean the foam air filter after every ride in wet, sandy, or dusty conditions.
- Inspect the filter for tears, excessive staining, or rigidity – replace with a quality filter if needed.
- If your RM85 feels down on power, bogs, or won't idle consistently, evaluate air filter condition before troubleshooting more complex issues.
Tools & Supplies You Need
- Clean nitrile gloves
- Metric socket set or wrench (to remove seat – typically 10mm or 12mm)
- New or freshly cleaned air filter
- Quality air filter oil – specifically for foam filters
- Bucket or tub with mild, filter-safe cleaner
- Grease (for sealing the filter rim)
- Paper towels or lint-free rags
Step-by-Step Air Filter Removal
- Remove the seat by loosening the seat bolts at the rear of the frame.
- Unclip or unscrew the airbox cover to access the air filter assembly.
- Reach in and carefully pull out the air filter and cage – check for any loose debris in the airbox. Wipe the inside of the box clean with a damp rag if necessary.
Cleaning the Air Filter
- Gently separate the foam filter from the plastic cage.
- Submerge the filter in a bucket of mild cleaner. Squeeze (do not wring or twist) to work dirt and old oil out of the foam. Repeat with clean water until the filter is spotless and residue-free.
- Allow the filter to air-dry completely before oiling.
- If the filter shows any rips, hardening, or significant compression set, replace it immediately to prevent dirt ingestion.
Oiling & Installing the Filter
- Apply air filter oil evenly throughout the foam. Massage the oil in, ensuring full saturation, but avoid pooling excess oil.
- Lightly coat the rim of the filter with grease to ensure a positive seal inside the airbox – an important step for the RM85's air intake design.
- Fit the filter back onto the cage, then install the assembly into the airbox. Align any locating posts or tabs properly.
- Secure the air filter assembly. Double-check for proper seating and contact all around the rim to keep unfiltered air from entering the engine.
- Replace the airbox cover and reinstall the seat, tightening all hardware according to the service manual.
Special Notes for the 2011 Suzuki RM85
- The RM85 airbox allows easy access for filter changes, but it's vital to inspect the sealing edge and surrounding air boot for any signs of dirt tracks, which point to filter leaks.
- This model benefits from installing a filter screen if you frequently ride in muddy or sandy conditions, as it adds extra protection against fine debris.
- Always use recommended filter oil and never run the RM85 with a dry or inadequately oiled filter.
Conclusion
A clean and properly oiled air filter is your RM85's best defense against engine damage and loss of power. With the steps above, you can extend the life of your bike and enjoy peak performance on every ride.
