I also have a ticking sound that someone told me that his R6 had made that noise the whole time he owned it, and it was fine. But that dosen´t mean anything, I don´t think that it should make that ticking but it dosen´t effect the way it runs at all, so I´ll just wait till it blows up then build the **** out of it and make it sick, can´t wait.... ha ha.
