Chain and Sprocket question?

I am sure this has been asked many times before. My Clymer manual shows the Chain as being a 630 thru 1981. However, nowhere, even in the suppliment for 1982 and later, does it show the chain size for my 1982 KZ750R or GPz. It lists the sprockets and ratios but no chain size for the 1982. Any help appreciated

Thanks,
Richard Z.

The 1982 KZ 750R has a 630 chain. It is part listed for that year model as: EK 630SX88. Go into the link below, click continue, then type in your info. You will eventually come to part numbers/descriptions/exploded part pics etc. This is applicabable to almost any Kaw year/model.
