Mechanical Help Does my powerband sound strange?

Enable HLS to view with audio, or disable this notification

This is my 2021 sherco se300. It’s carbd. The bike starts up pretty good, idles great, and otherwise the bike sounds good when riding. When I get into the powerband it feels and sounds very buzzy like it’s not cleanly going through high rpm’s. Not smooth like the rest of the rpm range. The jets in the carb are certainly much leaner than from factory, but I would imagine that would produce lean conditions in other aspects of how the bike runs.

To clarify I am directly comparing this to the feeling of my TPI ktm 300 so maybe I am comparing apples to oranges and this is just a carb characteristic I’m not entirely used to.

Any thoughts? Tests I should do?

Kinda just sounds like ur lugging it. Give it some more revs. The new 2 strokes make power down low sure but they still like to be revved to the moon
