To clean a K&N filter on a Harley Sportster, first, remove the filter from the airbox. Then, use a K&N cleaning kit, which includes a specially formulated cleaner and oil. Spray the cleaner onto the filter, allow it to soak for about 10 minutes, then rinse it with low-pressure water from the clean side to the dirty side. After it dries completely, apply the K&N oil evenly and reinstall the filter.
If it is a stock paper filter, no it needs replacing, if it is a k&n high flow, yes, clean it with k&n filter cleaner and rinse with gentle running water let it dry and oil the filter with k&n filter oil.
That's not a complete sentence, but the Sportster was introduced as a replacement for the K Model in 1957.

To clean a K&N air filter, you typically use K&N's own cleaning solution, which is specifically formulated for their filters. This cleaner is designed to effectively remove dirt and debris without damaging the filter media. After cleaning, the filter should be re-oiled with K&N's air filter oil to maintain its filtration efficiency. Always follow the manufacturer's instructions for the best results.

The frequency of cleaning a K&N filter depends on driving conditions and the environment. Generally, it's recommended to clean the filter every 25,000 to 50,000 miles, but if you drive in dusty or off-road conditions, you may need to clean it more often. Regular inspections can help determine when it needs cleaning, ensuring optimal performance and airflow.

Try 24 hr filter cycle and more chlorine. And clean the filter frequently. k
I use a mild dishwashing liquid and water mixed together then spray it clean with water under pressure such as a garden hose, let dry and then apply k and n oil. Works great everytime and I'm still using a 5 year old filter.
