Your 1987 Kawasaki KLR650 is an iconic dual-sport motorcycle known for its dependable design and rugged versatility. To ensure optimal performance and engine longevity, regular air filter maintenance is crucial. This guide, unique to MotoSport, covers the necessary care and specifics for your KLR650's air filter, whether you ride trails or tour long distances.
Understanding Your 1987 KLR650 Air Filter
- Type: The OEM air filter element (part number 11013-1152) is crafted to provide efficient airflow and top-tier filtration, capturing dust and debris common in off-road and dual-sport riding environments.
- Construction: Filters from leading manufacturers often combine multiple layers, typically with an outer coarse-foam to catch larger debris and a finer inner layer for tiny particles.
- Reusability: Most aftermarket options (K&N, DNA, etc.) are washable and reusable, making them ideal for long-term maintenance.
When to Clean or Replace Your Air Filter
- Inspect the air filter after every long or dusty ride.
- Clean the filter at least every 1,000 miles or as conditions require. For frequent off-road use, inspect and service more often.
- Replace the filter if it shows signs of severe wear, damage, or if it cannot be cleaned thoroughly.
How to Access the KLR650 Air Filter
- Remove the seat using the rear fasteners.
- Unclip and take off the side panel (right-hand side), exposing the airbox.
- Release the airbox cover fasteners and carefully remove the cover.
Cleaning the Air Filter (Foam/OEM Type)
- Carefully remove the filter, making sure not to drop loose debris into the intake.
- Tap out loose dirt. Rinse the filter in a bucket of warm water mixed with mild detergent–squeeze gently, never wring or twist.
- Rinse with clean water until it runs clear. Allow the filter to air dry completely (out of direct sun or heat).
- Once dry, apply air filter oil evenly if using a foam or cotton filter (follow manufacturer recommendations). Avoid over-oiling, which can restrict airflow.
Reinstalling or Replacing the Air Filter
- Ensure the filter is entirely dry and properly oiled, if applicable.
- Place the filter securely in the airbox. For aftermarket filters, confirm the seal is airtight to prevent unfiltered air from entering.
- Reattach the airbox cover, side panel, and seat.
Specific Tips for 1987 KLR650 Owners
- The 1987 model uses a rectangular filter element which fits snugly. Always check for a tight fit to prevent bypass and maintain filtration integrity.
- If using washable filters (like K&N or DNA), let the filter dry fully before oiling&installing, and use only the recommended filter oil, as incorrect oil can affect performance or filtration.
- Inspect the airbox sealing gasket for degradation each time you service the filter. An air leak here can allow harmful particles into the engine.
Why Routine Air Filter Maintenance Matters
- Proper filtration protects the KLR650's single-cylinder engine from premature wear caused by dust and debris.
- Caring for the filter helps maintain engine power, fuel economy, and throttle response–especially important on a bike known for adventure and endurance rides.
For the best results and longest engine life, make air filter care a standard part of your Kawasaki KLR650 maintenance routine. MotoSport offers OEM and aftermarket filter options so you can keep your dual-sport running strong ride after ride.
