I have an 02 foreman 450 es and when I engage my 4x4 I get nothing. I t has the traxlox on it from the factory. I know on my 06 500 foreman I can actually here it engage when I flip the switch. I am by no means an atv mechanic and have no idea of where or what to start checking. It seems to be a great running bike and I bought it for my kids but do not feel safe letting them ride it until I can figure out and fix the problem. Any help would greatly be apreciated. Thanks!!!
