Just had a tootle round on Saturday and that reminded me that every idiot is out on a bike (peddle) at the weekend plus a few who knew how to ride OK.

All running well but noticed that the tacho was reading around 900 rpm low, so completely zero at tickover! The digital tacho was reading true and everything else seemed OK, so pulled over and turned off the ignition and removed the key for a bit - that sorted it back to normal 550rpm at tickover.

Anyone else had similar ?
