clutch damper rubbers

[bazzer5115]

Can anyboby explain what the rubbers do on my 350ypvs clutch drum do?
Are they to damp any noise,are they required as one of mine looks a little damaged.Are there any advantages in fitting/not fitting them.Rebuilt many other bikes in the past and not seen them before?
Cheers

When I fitted upgraded race plates had to remove dampers or the set would not fit. A little noisier than before but no issues

they are v shaped cross section and when you pull the clutch I they help push the clutch plates apart to stop the clutch from dragging in my opinion they don't work as intended
and are better left out............
