Using your K&N air filter is easy. First, make sure your motorcycle engine is cool. Then, locate the stock air filter and carefully remove it. Place the K&N filter in its position, ensuring it fits snugly. That's it, you're ready to go! When it comes to maintenance, check the filter regularly. If it looks dirty, clean it using a K&N filter cleaning kit. This will help keep the filter performing at its best. Remember, never use harsh chemicals on the filter as it can damage the material. Always follow the cleaning instructions provided with the kit. Also, when installing the filter, double - check that it's properly seated to avoid any air leaks, which can affect your motorcycle's performance.
