Yes, it is probably your camchain that is worn. Test by pushing in just a bit more the plunger of the tensioner, as the spring is not strong enough to push it all the way. First remove the large 'coverbolt' on the tensioner L/H side of cilinder. If sound stops it is the camchain.
Another indication: remove coverbolt and spring on tensioner. Remove tensioner. Count number of notches out on the plunger. If more than 60% of total replace chain. Spring to be remoived first, otherwise the spring will push out he plunger all the way and you loose the actual reading of thenumer of notches.
Replacement of chain does not require new sprockets, see post about two months ago.
