Slow death wobble at speeds

[solidsnake2431]

This just started out of the blue for seemingly no reason. At around 65-70ish the front wheel now starts wobbling or walking back and fourth slowly when on the road. The bike has 200 miles. I have had many dirtbikes and other motorcycles never had this problem. Also for some reason crossing the doubble yellow lines will send it into this condition at slower speeds.

Could it be because the tires are not balanced. I noticed that adding air pressure to the back tire helped a little for sure but the front pressure had no effect on it.

Now I am afraid to drive at normal road speed because I am worried it will get worse
