If you wish to execute maintenance tasks on your Kawasaki Z 400 then it is always a great idea to have access to a Workshop Manual to keep just for a guide if perhaps you need to know proven methods to take off a specific part for example, the Brake Pads and match it again effectively.
Kawasaki Z 400 Workshop Manuals offer you particular diagnostic information for the vehicle so if something is faulty it can help you determine what the problem is and some ways to fix it. Then you are able to analyse if you can do this by yourself or in the event the job is too big you can still book your Z 400 in with a decent mechanic.
