If your handlebars are not in the center or straight, you can easily fix this issue. The clamp that holds the handlebars is always bolted through the top yoke. Under the top yoke, there are 2 nuts. Loosen these nuts slightly by turning them back for half a turn. Then hold the bars and straighten them easily.  It will also help to loosen the handlebar clamp so that the handles can shift inside the clamp. Simply loosen them and place the handlebars in the center. Then tighten all the attachments, and it's done.
