What is the method for cleaning a motorcycle's air filter?

Motorcycle's air filter cleaning method is: gently tap it on the ground to shake off some dust, then use an air pump to blow from the inside out to remove the dust. Functions of the air filter: 1. Ensure the air filter fits tightly against the housing to prevent unfiltered air from entering the cabin; 2. Separate dust, pollen, and solid particles from the air; 3. Adsorb moisture, soot, ozone, odors, carbon oxides, SO2, CO2 in the air, with strong and lasting moisture adsorption; 4. Prevent car windows from fogging up, ensuring clear visibility for the driver and safe driving; 5. Maintain clean air in the passenger compartment and prevent bacterial growth.
After years of motorcycle maintenance, cleaning the air filter requires careful steps: Turn off the engine and wait a few minutes for it to cool down. Locate the plastic box near the engine, commonly found on the left or right side. Use a screwdriver to remove the cover, being careful not to drop any screws. Take out the filter element and handle it according to its type: For sponge-type filters, soak them in mild soapy water for 5 minutes, gently brush off the dust with a soft brush, rinse thoroughly, and let them air dry overnight—avoid using a hair dryer to prevent deformation. Paper filters generally shouldn’t be washed with water; instead, use compressed air to blow out dirt from the inside out, or replace them directly with new ones. After drying, inspect the filter for any damage. If the bike requires a wet-type filter, apply a small amount of specialized engine oil before reassembling and tightening the cover. Remember to do this every 5,000 kilometers to prevent the engine from inhaling dust, which can lead to sluggish acceleration or high fuel consumption. The tools needed are just a screwdriver and a basin—keep it simple. This routine can significantly extend the engine’s lifespan.
I enjoy DIY motorcycle maintenance, and cleaning the air filter is simple and cost-effective. I choose a sunny day, first park the bike and turn off the engine, then locate the filter usually under the fuel tank, remove the cover, and take out the filter element. If it's a sponge filter, I soak it in water with mild dish soap for a while, gently scrub off dirt with an old toothbrush, rinse it, and let it air dry naturally—avoid direct sunlight. For paper filters, I can only blow out the dust or replace them. I always check the rubber gasket for aging while at it. After drying, I reinstall it ensuring a good seal. I do this every quarter or after riding on muddy roads to prevent dust clogging and engine efficiency loss. The whole process takes about 10 minutes. Using a bit of soap or specialized cleaner is inexpensive and saves on repair costs. Making it a habit keeps the engine running smoother with fewer issues.
As a beginner learning motorcycle maintenance, I found cleaning the air filter quite approachable. First, turn off the engine and let the bike cool down. Locate the air filter box, usually positioned near the side of the bike, then use tools to open the cover and remove the filter element. For sponge-type filters, wash them with water and soap, gently scrub, rinse thoroughly, and let them dry for a day or two. Paper-type filters should not be washed—either replace them directly or blow off the dust. The key is to avoid wetting other parts. Before reinstalling, check for any damage. Beginners often worry about causing harm, but the steps are actually simple. Following the manual or video tutorials ensures safety, and the tools required are basic and hassle-free. Doing this regularly protects the engine.
