Welcome to the site. It is indeed 2 ball bearings like in the manual. Resetting the tensioner is quite a low risk job in itself. The main problem really is removing the carbs to get to it which is a bit fiddly.
If it is quiet enough you can count the clicks as you reset the tensioner and see if your cam chain is at the end of its life.
