Do I need to mess with stock cam chain tensioner on an 8800 mi Bike?

I'm getting my old KZ13 running after sitting since 1996. Been in dry storage and looks to have survived well
Do I need to put a ZX11 Can Chain Tensioner in? Bike only has 8800 miles on it. What else should I look for? It MAY be FS...Thanks!

Very important to modify or replace the tensioner. Expensive engine damage can result from failure of the original design.
