Yamaha XV 1600 Wild Star Workshop Manuals will give certain diagnostic guides on your vehicle so if something is faulty it can help you work out what the situation is and some ways to correct it. You can then assess if this can be achieved by yourself or if ever the job is too big you are able to book your XV 1600 Wild Star right into a local mechanic.
