THROTTLE CABLES
There are
two
throttle cables:
an
accelerator cable
for opening
the butterfly
valves, and
a decelerator cable
for
closing
them.
If the
cables
are too loose due
to
either cable
stretch or
maladjustment,
the excessive
play
in the throttle grip
will
cause
a
delay
in
throttle
response, which
will be
especially noticeable
at
low
