Measuring the chain slack is not easy: A ruler is not easy to position, you get dirty....
So I have made this simple instrument with a picece of hard wood. Cut an angle of the piece and mark the zone width a with from 44mm to 49mm. The recomended slack is 51mm to 56mm but measured to the center of the chain, what adds 7mm.
It is useful to tape a small mark in the swingarm where the measurement has to be made.
With this tool daily chain measurement is possible, easy and clean.
