NOTE.·~
_
High altitude specifications apply to operation at an altitude
of
more than 1506 meters (4500
tt),
Since the clutch weights are secured in place
by the
sheave
cap bolts, the centrifugal force
that
can alter clutch characteristics comes
from the weight
of
the lever on the spider. To
adjust clutch engagement and clutch shifting
rpm, add or remove roller shims
from
the
spider as indicated by the chart .
.Clutch shifting rpm can also be adjusted by
changing the preload on the secondary
sheave
spring: 160
