It is generally recommended to replace the air filter every 15,000 kilometers. For motorcycles frequently operating in harsh environments, replacement should not exceed every 10,000 kilometers. Extended information: Air Cleaner/Air Filter: Primarily used in pneumatic machinery and internal combustion engines, its function is to provide clean air to these mechanical devices, preventing them from inhaling air containing impurity particles during operation, which could increase wear and damage probability. Components: The main components of an air filter are the filter element and the housing, where the filter element is the primary filtering part responsible for gas filtration, and the housing serves as the external structure providing necessary protection for the filter element. The operational requirements for an air filter include the ability to perform high-efficiency air filtration, not adding excessive resistance to airflow, and being capable of continuous operation over long periods.

I've been riding motorcycles for five years, and the air filter is that thing that protects the engine's air intake. Usually riding in the city where there isn't much dust, I generally check it every 3,000 to 5,000 kilometers. When I open it up and see the filter element is dusty and dirty, I either blow it clean with compressed air or wash it directly with water, let it dry, and then put it back. Remember when off-roading in dusty areas, I need to be more diligent, maybe cleaning it every 2,000 kilometers. Otherwise, if it gets clogged and can't suck in air, the engine will struggle, lose power, make loud noises, and consume more fuel. Regularly keeping it clean ensures the bike runs smoothly and extends its lifespan—don't wait until there's a problem to fix it, as that'll cost more. Developing the habit is pretty simple; doing it yourself takes just about ten minutes, making it both convenient and safe.

Regarding air filter cleaning frequency, it really depends on the environment. I often ride on mountain roads where there's heavy dust, and the filter gets clogged quickly, so I basically check it every month. If you only ride on clean roads, checking every two to three months might be sufficient. The key is to observe the color change of the filter element—if it turns white, it's clean; if it's gray or dirty, address it promptly. When cleaning, avoid using hard objects to poke through it; gently blow off the dust or replace the filter to prevent small issues from becoming big ones. By the way, while cleaning, take a quick look at other components, such as the carburetor connection, to ensure there's no air leakage. Long-term neglect can lead to increased engine carbon buildup, higher fuel consumption, and even sudden stalling, which is quite dangerous. Don't skip this small detail just to save trouble.

Regularly cleaning the air filter is a money-saving trick. I commute by motorcycle and clean the filter element myself every 4,000 kilometers. Simply disassemble the housing, blow off the dust with a hair dryer or wipe it with a cloth. A new filter costs only a few dozen yuan, but using it sparingly and cleaning it to extend its lifespan can save on repair costs. The engine breathes smoothly, the bike runs smoothly and saves fuel, allowing an extra few dozen kilometers per tank. The key is timing—don't delay too long, as dirt can affect performance. Learning to do it yourself means hardly ever needing to visit the shop, saving on labor costs—worth the time spent. On the road, avoid lingering in dusty areas for better protection.
