My experiences and feeling to that issue is that it also depends on the outside temperature and the clutch/variator/gear temperture. Sometimes its better, sometimes worse and sometimes pretty smooth like almost gone. I don´t care much anymore as long as it works and gets me to the places where I want to be. If I needed a replacement one day because of worn clutch/facings, I would look for a quality aftermarket product.
But maybe this chatter is also (partly?) caused by the belt slipping somehow. Who knows.
By the End of July I might reach 10.000km on mine and will rip apart the drivetrain for a closer look, at least cleaning everything and changing the belt.
