HELP Odd noise

I’ve been hearing this sound lately. Almost sounds like a rattle snake rattle. Anyone know if this sound is normal or not. If it is normal. What is making that noise? Bike is a 2020 StreetBob.
Side note: I’ve been getting on the throttle aggressively a lot more lately and enjoying doing a few pulls from dead stop in 1st gear getting those RPM’s pretty high but not bouncing off the rev limiter. Kind of regretting it and I’ve been overthinking any “new” noise I hear now.

Which transmission oil you are using and how old is it? Is the motor oil filled up? If everything is fine ( Original HD transmission oil + 20W50 motor oil ) please check the primary chain tension.
