If you wish to perform auto repairs to your Honda XL 600 LM then it will always be a good idea to own a Workshop Manual to use as personal reference if you want to know methods to strip off a particular component such as the Exhaust and install it again in the correct way.
Honda XL 600 LM Workshop Manuals are able to offer specified diagnostic guides for the vehicle so if something is faulty it helps you identify what the situation is and tips to correct it. You can then determine if this can be achieved yourself or if the job is too big you could book your XL 600 LM right into a nearby garage.
