Adjusting The Engine Idling Speed - Yamaha FZ6RC Service Manual

TIP
The thickness "a" of each valve pad is marked in
hundredths of millimeters on the side that touch-
es the valve lifter.
Example:
If the valve pad is marked "158", the pad
thickness is 1.58 mm (0.062 in)
d. Calculate the sum of the values obtained in
steps (b) and (c) to determine the required
valve pad thickness and the valve pad num-
ber.
Example:
1.58 mm (0.062 in) + 0.05 mm (0.002 in) =
1.63 mm (0.064 in)
The valve pad number is 163.
e. Round off the valve pad number according to
the following table, and then select the suit-
able valve pad.
