Calculate the maximum admissible re-cutting dimension
–  Introduce the valve and press it hard against the seat.
  Note!
If the valve is changed during the reparation, use the new valve for the measurement.
   
–  Measure the distance -a- between the end of the stem and the upper edge of the cylinderhead.
–  Calculate the maximum admissible re-cutting dimension starting with the distance measured -a- and the minimum dimension.
Minimum dimensions:
Intake valve 43.4 mm
Exhaust valve 43.2 mm
Distance measured less the minimum dimension = maximum admissible recutting dimension.
