BMW double R racing engine

Moin from the north, I need your expertise, and I own a bmw s1000rr bj 2011, maybe someone also has a bmw or even a bmw s1000rr. To my question, from a speed from 40 kmh or from 3 to 4000 revolutions the engine rattles during the ride. As soon as I pull the clutch it is gone, I have heard that the engine from the noise background makes so many noises and you should get used to it -,- . Well, the control chain was first changed Of course, I was in a workshop again, which also drove the test and said it was all right. BUT! You love his motorcycle accordingly you still keep on thinking if that really belongs to that. It could also be a vibration story, in turn it would not make sense if the rattle after I pull the clutch away is, maybe the chain is just too loose, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no. I don’t know, maybe someone’s had similar experiences.
