Hey. I have a '97 Polaris Magnum 425 4x4, push button AWD .... Well here recently it has been engaging into 4wd without me pushing the button. Like just will randomly go into 4wd when i dont need it to, or when im climbing a hill it will engage? Can someone give me some things i can check to see why it is doing that? And another question, is it bad for me to keep riding it like this?
