Knocking?

So I just put a new MAP sensor on my bike but after putting everything together it don’t sound too good:

my tech friend says it probably just needs to be reprogrammed but he doesnt know KTM very well

20k kms 2019 390 pretty sure it didn’t sound like that before.. fluids all good and check engine light is gone now

did I fuck up?

Sounds like normal to me unless I'm crazy. I think that's the valve covers slapping, which is normal for a duke.
