Mine still clicks (sounding like several soft electrical mouseclicks), but only after about 150km of riding ....strange, isn't it? Seems that the clicking sound only appears when the bike is really hot or something.
Well, today I made a tour of couple of 100 kilometers, but almost immediately the clicking sound started and was hearable all of the tour, so it isn't engine heat related I think. It was about 30 degrees Celsius outside.
I think it's coming from the airbox or injection system ........
