Hi All,
My super spec recently failed SVA at Shrewsbury on a number of minor points most of which are now done.
However one of the failures was on speedo calibration. I had fitted the blue/grey speedo drive gear with 25 teeth (can't remember the part no) but the inspector said that this was showing 2mph less that the true speed @70mph. Should I revert to the yellow gear or would this make the situation worse or is there another gear I could use.
