My neighbor bought this four wheeler and had never heard it run. He brought it home and asked me to take a look at it and get it going for him. It now runs and the standard shift is working fine, but it will not shift out of Super Low. So i'm asking for some help in trying to determine what I need to do to try to find and correct the problem. I just got the four wheeler today and have done NOTHING to it today. I'm hoping this is an easier fix than his Rubicon 500 was. THank you for any input you might give me.
