Measure the outside diameter [D] of the seating pattern on the valve seat.
If the outside diameter is too large or too small, repair the seat (see Valve Seat Repair).
Valve Seating Surface Outside Diameter Standard:
Exhaust 23.9 24.1 mm (0.941
0.949 in.)
Intake 30.4 30.6 mm (1.197
1.205 in.)
Measure the seat width [E] of the portion where there is no build-up carbon (white portion) of the valve seat with a vernier caliper.
Good [F]
If the width is too wide [G], too narrow [H] or uneven [J], repair the seat (see Valve Seat Repair).
Valve Seating Surface Width Standard:
Exhaust 0.8 1.2 mm (0.03
0.05 in.)
Intake 0.5 1.0 mm (0.02

the tires until they are bald.
Measure the tread depth a ...
