Air Filter Cleaning & Replacement Guide for 2007 Suzuki RM85L
Shop parts for a 2007 Suzuki RM85L Dirt Bike.
The 2007 Suzuki RM85L is a competition-grade mini motocross machine, famous for its high-rev two-stroke engine performance. To sustain peak horsepower and throttle response, regular maintenance of the air filter is critical–especially for a bike that thrives on clean, unrestricted airflow.
Why Air Filter Maintenance Matters on the RM85L
This RM85L features a high-output 85cc engine with sensitive carburetion, making optimal filtration essential. A clogged or deteriorated air filter limits power, increases engine wear, and can even cause premature engine failure. Since this bike is often ridden in dusty, off-road conditions, cleaning or replacing the air filter should be a routine part of every ride day.
Choosing the Right Air Filter
- Dual-layer foam filters are standard for off-road use and the RM85L, offering excellent dust filtration and airflow. Suzuki-specific options like Twin Air, HiFloFiltro, and Maxima ProFilter provide direct-fit solutions with dual-stage foam for depth filtration and optimal performance–several of these are washable and reusable, but disposable oiled filters are available for minimal maintenance–check your filter type before cleaning or discarding.
How to Remove the Air Filter on the 2007 RM85L
- Locate and remove the seat by loosening the bolts under the rear fender, then slide the seat backward to access the airbox.
- Unfasten the airbox cover clips and gently pull off the cover.
- Remove the air filter from the mounting plate by unscrewing or unclipping the central retaining bolt. Take care not to drop dirt into the air intake tract.
Cleaning and Oiling the Air Filter
- For washable foam filters (such as Twin Air or HiFloFiltro), gently wash off large debris, then submerge the filter in a bucket of air filter cleaner or mild detergent. Work the dirt out by hand, rinse well, and squeeze gently to avoid tearing seams.
- Allow the filter to dry completely before proceeding (do not use high heat).
- Coat the entire filter with foam air filter oil, massaging the oil into the foam to ensure even coverage. Do not over-oil, as excess oil restricts airflow. Specialized filter oils are recommended for maximum dust protection and engine safety.
- If your filter uses a grease-less sealing ring (common on certain aftermarket models), ensure a proper seal around the rim when reinstalling.
- For disposable pre-oiled filters (like Maxima ProFilter RTU), simply discard the old unit and replace with a fresh filter–no cleaning required.
Reinstalling the Air Filter
- Inspect the airbox for dust or dirt. Wipe with a clean, damp rag before installing the clean filter.
- Reattach the filter, ensuring it is fully seated and the mounting plate or clip is secure.
- Reinstall the airbox cover and seat, following the reverse steps of removal.
Tips & Model-Specific Notes for the RM85L
- The RM85L uses the same air filter design from 2002-2014, giving riders broad aftermarket options for replacement.
- OEM and most aftermarket filters have foam designed for repeated cleaning–disposables are an option for race weekends or time-saving needs, but are not reusable.
- Always inspect the filter cage and sealing surfaces for any cracks or warping before reinstallation, as this can let dirt bypass the filter.
- Check the rubber mounting grommet for tears or wear–a poor seal can lead to catastrophic engine damage due to dirt ingestion.
- Given the small displacement and high-revving engine of the RM85L, filter maintenance intervals should be even more frequent if riding in sandy or especially dusty terrain.
Recommended Cleaning & Replacement Intervals
- After every major ride or race in dry/dusty conditions: Remove and clean or replace the filter.
- Otherwise: Inspect after each ride; clean every 3-5 hours of riding, or sooner if the filter appears dirty.
- Always replace filters showing signs of permanent clogging, foam breakdown, tears, or seam failure.
Keeping your 2007 Suzuki RM85L’s air filter fresh is a simple process that yields serious benefits, protecting your investment and ensuring top-level performance ride after ride.
