2017 Street Cup Noise Problem

Hello guys, I think I need some help, I not sure is this a normal sound for the street cup's engine? I not sure what problem could it be. Valve or cam chain, i don't know.
But this noise only came out when engine is hot.
This is the sound when the engine is cold.


And there is the sound with a hot engine.

 

Thank you for the response but the local dealer is so far from my home.
I plan to take my bike there soon.

 

3800km,I think so too,still wanna ask could it be the cam chain's problem.
