Calculate your K-Value?

Example

K = 10 x number of revolutions of the rev meter cable / tire size in cm.

You can determine the number of revolutions of the rev meter cable: remove the km counter cable from the odometer. Put a paper clip on the square inner cable and turn the wheel exactly 10 times (note on the tyre).

Meanwhile, count the number of revolutions that the paper clip/rev meter cable makes.
For example: 10 x 27.5 revolutions / 202 cm = 275/202 = 1.36 is rounded 1.4
