@Jung Wasn't the tensioners. They were spotless. Seems like new cam chains. This will be very interesting.
The tensioners come out clean but the self regulating spring can weaken and that affects the ratcheting mechanism. Seems odd as your bike isn't that high mileage.
Are you doing the chain replacement? Does it need the sprockets replaced too?
