Recutting the valve seats
Clean carbon and deposits from the valves. Apply some “Prussian blue” to the
valve face and lap it against the seat with a suitable lapping tool. Remove the
valve and measure the width “X” of the contact surface. If the width exceeds
0.06 in. the seat should be recut.
Standard width of the contact surface is:
A = 0.0354÷0.0433 in. for the INTAKE
A = 0,0354÷0,0394 in. for the EXHAUST.
The valve can not be ground. If the valve is damaged replace the
valve.
