Waiting on the manual tensioner from Mark Krieger to be produced. Sent off some measurements and pictures.
Hope it will be soon. Don't want to put another automatic tensioner on it really. Also the manual tensioner will make it easier to install the cams and to set the timing marks more easily. It took me nearly 10 or so tries to get the timing mark set up properly with the stock setup.

The WRR I bought has 10,000 km on it and it too sounds like the cam chain is slapping around a bit.
Especially when you rev the bike and the revs fall back, there is a clatter at a certain rpm.
Have you resolved your would be tensioner issues.
As far as the timing chain is concerned mine on my WRF was stretched at 6000 Km as cam marks could no longer be aligned, so I replaced it. It's good that the R model is not wearing them out as quick.
