Guys
I've been in communication with Quaife and our production supply team, I've asked that they keep me copied in with communications.
I'm lead to believe that a number of factors can contribute to the perceived noise, belt tension and alignment being the primary factors.

Thanks Mark - would be interesting to see what can be done about improving belt tension and alignment (tolerences)... I'm guessing something like a jig for dealers would be ideal!
