rev needle bounce

[Bibio]

K7 twin spark.

i have never noticed this till now as i have always had a spaznav stuck to the rev counter. keeping a steady speed of say 60mph the rev counter needle bounces a little.

anybody else notice this or do i need to investigate?

its not bounce as such and more of a flutter of a few revs. all the connections are clean and have been sprayed with acf-50 then air dusted so there is just a light coating.

its no biggie in the grand scheme of things and wont notice when i stick the spaznav back on.. lol

might get the sds tool out and do a reset.

May be vibration causing it on an analogue speedo, either from road or engine.
