The tacho needle is erratic in the video - why so?
sticky mechanical cable?

I haven't seen the video - but my favourite reason for such variation is scrabbling for grip, less so when its an open diff in a long corner, but all the same.

Mechanical tacho? Maybe the cable is snatching or there might be wear inside the casing so that the drive magnet is catching or getting too close?

Am now thinking the tach might be chronometric.  Posh 50s GP cars have them.  Some old british bikes.  The needle flicks between readings.
