Where is the cam chain tensioner located on a Kawasaki?

How do you tighten a cam chain tensioner?
Slip the ball bearing and retainer spring over the pushrod. Place the assembly over the crankcase mounting position and insert the tensioner pushrod into the hole. Put a drop of blue Loctite on both mounting bolts. Tighten them by turning each a bit at a time.
How does a tensioner attach to a crankcase?
There are 2 bolts that hold the tensioner to the crankcase. The tensioner is under pressure from a rather strong spring, so be sure to back the mounting bolts out a little at a time on each side so the tensioner assembly does not become “cocked”. Take special care toward the end of the mounting bolts’ travel.
