The purpose of the air filter is to filter the air from dust & any stray particles that may damage the engine internals. An air filter over a period of bike’s usage gets clogged with dust. It decreases the air flow & makes the bike run slightly on the richer side thereby decreasing the fuel economy & affecting the performance negatively. Hence it is recommended to clean it regularly. More so when the bike is subjected to riding in dusty conditions.
This is a detailed post of the process of cleaning the foam type air filter at home for the DIY enthusiast. During the process of cleaning the hands will get dirty. If the job is done carelessly one may end up throwing kerosene or diesel on his clothes as well. Happy cleaning.

Tools required:
Just Kidding

Screw Driver

Air blower (Vacuum Cleaner)
Cleaning Agents required:
I just used Kerosene,cant waste petrol

and a plastic mug
Procedure:
- Keep the bike on center stand.

- Open the LH side cover.

- Open the bolt of the air filter cover using a screw driver pull it out




- Pull out the dirty air filter




- Take Kerosene in the mug and dip the air filter and clean it rigorously.


- Now fold the air filter from the middle & gently rub it thoroughly. Now squeeze it completely till all the dirty liquid are squeezed out.After cleaning it thoroughly gently squeeze the air filter using both your hands. Caution: Do not twist & squeeze the foam air filter as it will damage it.
- Now blow air all over the air filter using a air blower so that all the remnants of Kerosene & Diesel are removed from it. In my case I have a blower i.e. vacuum cleaner
- Now take the air filter & pour a few drops of oil on the filter. Preferably use engine oil (any grade will work) as it is used by all the service centers. This is used so that the dust & the particles in the air stick to the air filter easily.
- I have used 2T oil here.costs around 8 bucks and the remaining oil can be used to oil the chain.





- Now put back the air filter into the metal glass kinda thing.

- Fit the LH side cover back.

Precautions:
- Never turn on the bike without the air filter. Foreign particles can enter into the chamber & damage the engine internals.
- Don’t let any dust enter the air filter box when it is open.
- Handle the air filter with care. Don’t twist it unnecessarily. Squeeze it gently using both hands.
- Make sure u do not use petrol or WD40 for cleaning the air filter. Petrol & WD40 are chemically more reactive & will damage the foam filter by breaking it down thereby reducing its life & adversely affecting the filtering efficiency. Use either Kerosene or Diesel which are relatively less reactive.
- Make sure u don’t dip the foam in water. Incase dropped in water let it dry completely for ample amount of time under the sun.
- Store the fuels in a safe place away from sunlight or any other source of heat.
- Make sure u have a vessel of proper size to collect the dirty fuel dripping down. In my case i have used my backyard where my bike is washed.
