Cam chain clicking away eh? Sure sounds a bit like it.Did cross my mind the other day,but that sort of thing is hard to distinguish to the untrained ear.The last bike i had with a cam chain rattle was a GPZ 500s years ago.Didn't get time to sort it as a kindly old neighbour reversed into it and wrote it off.Saved me trying to flog it..phew.One bike fixer bloke once told me if you were very careful on tick over,you could loosen the adjuster until the clicking stopped,then carefully tighten the lock nut up

.Is it fairly easy to tension the chain?.New BT45 to fit this week end if the weather warms a little

Warming by the fire with a pint of cider,Pete.
