A long time ago I had a cable driven tach that failed. Of course it did not just break all the way, it would only go to about ¾ of red line. The problem never showed itself on the street. I don’t remember if it caused a problem at the track but I do remember revving it up in the shop till the valves floated, this was before rev limiters.
When Seed told me his ’91 RGV250 was cutting out on top and that he had good plugs and caps, a common problem on TZ250’s. I told him to check his tach and as he had a good spare this was easy to do. Problem solved.
