Welcome aboard! Nice bike! Here's a link to some info that should be helpful in maintaining your bike.

Until you can get a hardcopy, here's a link to an electronic copy of the Kawasaki Service Manual that covers your bike. The 1982 GPz 750 is the KZ750-R1. This manual contains info on that model (model list is on last page of manual).

Regarding parts cross reference; Kawasaki.com is a great site that has that info. Here's how to use it.
Go to Kawasaki.com. On left side put cursor over "Owner Information" then on drop down menu click on "Parts Diagrams." The click "Continue" next to "Motorcycles" and click on model/year/etc. on drop down. Once you get the list of parts for your bike you can click on the category of parts - such as "Air Cleaner" and you will see a diagram of all the parts for that category. Then when you click on an actual part number on the list under the diagram it will say if the Item Status is "Active." If it is "Active" Kawasaki still sells the part through dealers. Also, at that little page you can click on the yellow highlighted question mark for a cross reference of which bikes share that part or click on the red highlighted S to see earlier part numbers for the same part.
If you want to change bike models you can enter the new model at the top. Also, you can put in just the first part of the model (i.e. KZ650) and it will list all the years and sub models. You also can put in a part number up top and switch the word "MODEL" to "PART NUMBER" using the little drop down in that box. If you do that it will show all the models that part is used on.
Good luck with your "new" bike.
