If you wish to undertake auto repairs on your Jawa 350 TS then it is always a good idea to own a Workshop Manual to use as a reference if you want to know how to strip off a particular component for instance the Drive Shaft and match it again accordingly.
Jawa 350 TS Workshop Manuals will give distinct diagnostic information on your car so if something is not working it can help you find out what the problem is and ways to make it better. Then you are able to evaluate if you can do this on your own or that the job is simply too big you can still make a booking for your 350 TS right into a decent repair garage.
