      it is useful in case engine conks out and mech tries to rip you.ex.-
      mech ur bike's rings r gone.
      u-check the ring end gaps for with the std.values and decide.
      mech.-u need work on head,valves need grinding,other work.
      u-measure valve head thickness,valve stem thickness.
      same goes for crank if u r asked to get it trued on a lathe,u know the values for stock setup and can measure with a vernier scale.or else trust ur mech blindly.
