Cam chain rattle?

The last Kawasaki I had made a rattle.

I was advised to take the end out of the tensioner ( just the cover not the 2 small bolts holding it on) and push on the plunger inside.

apparently K's have quite large steps in the auto tensioner allowing it to be quite loose before it clicks over one notch.

The bad news is that I was working on a KLR 650 single and the tensioner was easy to get at.
Yours might be a little harder to access
