Speedo damping?

[dalec]

Hello.
I have a 750f1 speedo apart for refurb, but it has no damping.
What substance should i use & where do i put it?
Obviously i dont want a bouncy needle on a rebuilt speedo.
I already have clock needles like windscreen wipers on my T500. Most annoying.
So your help would be appreciated.
Brodie.

I have the same issue on my '82 Supersport. I had assumed it was a cable cleanliness/lubrication issue. It's on my list.

Inside there’s a pot with a silicone fluid for damping
