Why Air Filter Maintenance Matters

This model’s robust engine depends on a clean, well-oiled air filter to keep dirt and contaminants out. Neglecting air filter maintenance can lead to reduced power, poor throttle response, and in the worst case, engine damage.–

How Often Should You Clean or Replace?

  • Clean every 10 hours of riding if conditions are dry and dusty.
  • Replace if torn, excessively dirty, or not sealing properly.
  • Inspect after every ride in heavy dust, sand, or extreme mud.

Tools – Materials Needed
