  • You should clean the air filter about once a month on a regularly used ATV.
  • If it has been a while, the air filter cover may stick and need to be pried up with a flathead screwdriver.
  • Be very careful when removing the air filter cover so as not to damage the gasket seals. If you damage this gasket, or if it looks worn, you will have to replace it.
  • Breaking the seals or tearing your air filter will allow dirt and debris into the engine which can cause engine damage.
