Hope you know that by changing the filter by its self won't fix this problem. I have had the hose between the air box and the intake come off twice at the intake side. This allows dirt and sand to be sucked directly into the motor. This is a devastating problem and should be fixed before you go out riding. Especially if you are out of warranty. I was under warranty and they have given me a new top end. however, the original problem has not been fixed
or attempted to be addressed. Go Figure.
