Where is the air filter in 2000 suzuki marauder 800

There are two of them. One for each carb. The rear one is just in front of ht battery box under the seat. It can be removed by removingn the 4 screws under the right side cover. The front one is under the tank. you must remove the tank then remove the air box from the frame it's the black box near the handle bars. once the air box is removed the filter comes out the same as the rear one.
