Sorta looked like somehow, it was connected to the inside of the inner cover and the transmission is on the opposite side.
Now see it's on the outside of the primary

Not until 2020 does Harley show it in the fish on the M8
Kept reading on here about oil transfers between the three areas and a retrofit of a external vent on the primary.
Did it take Harley 4 years to correct an issue with their vent system?

It is an inertial damper, it moves out of sync of the vibration of the cover, this can reduce vibration or change the frequency of the vibration to keep the component from vibrating at it`s critical frequency.

I was curious to know if its actually needed. Ive heard others saying to leave it out.
I thought it had to have a purpose, so I decided to put it back (hence question for torque spec).
Also Im using red loctite as I definitely do not want it to come loose, but Ive heard others saying to use blue loctite. I dont plan on removing it again so it should be fine using red loctite, correct?

Blue is all you need.
Have you been hearing of these things falling off? No.
