If the speedometer needs repair and you fix the problem by changing the gear you will then have a problem with the odometer. Charlie Stephens

The standard gear for 4:11 is 21teeth. Speedometer accuracy is affected by tire size and inflation, as well as condition of the speedo itself. Five percent variation isn't rare.
