I just got a king quad 700 2007 and I rode it for about 5 hours the other day and at the end of the day all the sudden it would not come out of 4 wheel drive. Also the diff will not lock now, it just flashes. The button is functioning and I pulled it apart and its clean so its not gummed up. Anyone ever experience this and know how to fix it. I want to race it but dont plan on running in 4 wheel drive the whole time.
