If you wish to accomplish maintenance to your Gilera Zulu 50 then it is usually a great idea to have a Workshop Manual to keep just for personal reference if you need to know tips on how to take out a particular component for instance the Drive Shaft and install it again perfectly.
Gilera Zulu 50 Workshop Manuals will give you special diagnostic info for your vehicle so if something is not working it helps you determine what the problem is and methods to make it better. After that you can analyse if this can be achieved yourself or if the job is too big you could book your Zulu 50 in to a nearby car garage.
