5. Setup & Installation
This air filter is designed for universal fitment on motorcycles. It is crucial to select the correct diameter to match your carburetor's mouth outer diameter.
Installation Steps:
- Measure Carburetor: Before installation, carefully measure the outer diameter of your motorcycle's carburetor intake. Select an air filter with a matching inner diameter.
- Remove Old Filter: Disconnect and remove your motorcycle's existing air filter system. This may involve loosening clamps or bolts.
- Position New Filter: Slide the rubber connector of the new high-flow air filter onto the carburetor intake. Ensure a snug fit.
- Secure with Clamp: Use the provided adjustable clamp to firmly secure the air filter to the carburetor. Tighten the clamp until the filter is securely in place and cannot be easily dislodged. Do not overtighten.
- Check Clearance: Ensure the newly installed air filter does not interfere with any other motorcycle components (e.g., frame, fuel tank, engine parts) during full range of motion or operation.

6. Operating Principles
Once installed, the high-flow air filter operates passively to enhance your motorcycle's performance:
- Increased Air Intake: The design allows for a higher volume of clean air to enter the engine, which can lead to increased horsepower and improved throttle response.
- Efficient Filtration: The dual-layer steel mesh and non-woven fabric effectively catch impurities, dust particles, and foreign matters, preventing them from entering the engine. This helps to prolong engine life and maintain optimal performance.
- Engine Protection: By filtering out harmful particles, the air filter reduces engine wear and tear, contributing to better mileage and overall engine health.

7. Maintenance
The Universal High Flow Air Filter is designed for repeated washing and reuse, ensuring your engine always receives fresh, clean air.
Cleaning Instructions:
- Remove Filter: Carefully remove the air filter from your motorcycle by loosening the clamp.
- Clean: Gently rinse the filter with water to remove accumulated dirt and debris. For stubborn dirt, a mild detergent can be used, followed by thorough rinsing. Avoid using high-pressure water jets directly on the filter material.
- Dry: Allow the filter to air dry completely before reinstallation. Do not use heat guns or direct sunlight, as this may damage the filter material.
- Reinstall: Once completely dry, reinstall the filter following the steps in the "Setup & Installation" section.
Regular cleaning, depending on riding conditions, will maintain optimal engine performance and filter longevity.
