It is quite common for the chain to have that loose slapping sound in between the take up points of the tensioner. At times they can sound bad for weeks on end then one day it is quiet till the chain wears a bit more etc. Don't panic yet ! If you install the extenders too soon you can damage the chain runner seriously enough to create a catastrofic situation. The tensioners must be near bottom of stroke before needing them.
If your tensioners are at full extension, then you will be able to use the extenders, BUTT be aware that when the chains wear and get longer, the cam's are being retarded by an equal amount, and the only true fix is to put on new chains, which admittedly is an ordeal requiring top end and side covers removal.
Retarded cams are noticeable and a worn chain can put it back by approx 3 deg. If you check it out you will find that the specs for cams and timing are usually spec'd out to a few Minuit's of a degree !
