If you wish to do adjustments on your Yamaha XT 600 K then it is always a good plan to own a Workshop Manual for a guide if perhaps you want to know the best way to take off a particular part such as the Brake Discs and match it again appropriately.
Yamaha XT 600 K Workshop Manuals will give distinct diagnostic guidelines with regards to your car therefore if something is not working it will help you figure out what the issue is and how you can resolve it. You can then decide if this can be achieved yourself or if the job is simply too big it is possible to make a reservation for your XT 600 K right into a nearby garage.
