navada 750 speedometer problem

[zari]

Often the speedometer starts to jump and that as a result of the snail flap that sits on the wheel just buckles something causes snail stuck for a moment and then the wheel keeps spinning around twisting it out I greased the cable and the snail, but the phenomenon continues Should I check the clock itself?

Yes, but I reckon it's probably the cable.
