VALVE AND SPRING
Insert the valves, with their stems coated with
SUZUKI MOLY PASTE all around and along the
full stem length without any break.
Similarly oil the lip of the stem seal.
Install valve springs, making sure that the
close-pitch end of each spring goes in first to
rest on the head. The coil pitch of both the inner
and outer springs vary: the pitch decreases
from top to bottom, as shown in the illustration.
CAUTION:
When inserting each valve, take care not to
damage the lip of the stem seal.
Fit valve spring retainer, compress spring with a
valve lifter and insert cotters.
