i think i got the same problem. I installed the R1 and had to undo the tensioner but its got a little bit of noise at the moment so i think it needs wearing in again..

JMM has previously said the dev 5 cam profile is prone to causing timing chain noise.

and ebs_4l has previously said to fit a stiffer tensioner spring, this has worked on others with (not so much big, but rough) cam profiles...
where to get one, take yours out, take it to a spring maker, and have one made with a lot more tension.... i found a spring laying around that worked. ive had custom springs made by a spring shop before, only cost me $50 for 10 custom made stainless springs made to my dimensions

it also could be the tensioner is not set propally
