Sample
Applications:
Retune
your
shim
stack
to
match
a
specific
clicker
setting:
A
common
tuning
problem
is
needing
to
"re-center"
the
clickers
to
produce
a
softer
or
stiffer
suspension.
This
example
retunes
a
stock
stack
to
be
three
clicks
softer
by
adding
a
crossover
shim
and
adjusting
the
stack
clamp
shim

.
Oil
Viscosity:
Tune
your
stack
to
duplicate
5wt
oil
performance
using
10wt
oil
Suppose
after
putting
5wt
fork
oil
in
you
bike
you
fell
in
love
with
the
feel
of
the
suspension.
You
want
to
switch
back
to
10wt
oil
but
maintain
the
suspension
feel
of
the
lighter
weight
oil.
What
changes
to
the
shim
stack
do
you
need
to
make
the
stack
behave
like
it
was
working
with
5wt
oil?

Cavitation:
ReStackor
pro
calculations
are
capable
of
determining
suspension
cavitation
limits,
the
suspension
velocity
where
cavitation
initiates,
the
magnitude
of
the
cavitation
event
and
the
performance
of
the
suspension
when
driven
beyond
the
cavitation
limit.
This
gives
you
the
capability
to
tune
the
stiffness
of
the
base
valve
shim
stack,
mid-valve
shim
stack,
mid-valve
float
and
bladder
or
ICS
pressurization
system
to
control
cavitation
and
the
suspension
performance
when
driven
beyond
the
cavitation
limit.
Weight
Scaling,
Correct
damping
rates
for
a
spring
rate
change:
A
popular
application
for
Shim
ReStackor
calculations
is
scaling
of
the
stock
damping
rates
to
correct
for
a
spring
rate
change.
The
scaling
process
restores
the
balance
of
weight,
spring
rate
and
damping
the
manufacture
intended
for
the
phantom
weight
of
the
stock
rider.
While
the
calculations
may
not
give
you
the
optimum
damping
for
the
speed
and
terrain
that
you
ride
it
does
provide
a
solid
starting
point
to
begin
the
tuning
process
on
a
new
bike.
A
special
worksheet
is
included
with
the
ReStackor
demo
software
for
these
calculations.
This
example
walks
you
through
the
calculations
needed
to
correct
for
a
spring
rate
change

XR650:
Borynack
Valve
Stacks:
For
those
of
you
with
an
XR650
that
have
not
seen
Bruce
Borynack's
web
page
let
me
introduce
you.
Bruce
has
several
valve
stack
recommendations
for
an
XR650.
A
common
question
is
"How
do
these
stacks
compare
to
my
stock
stack?".
This
example
compares
Borynack's
stacks
to
the
stock
valve
stack

CRF450:
Correcting stock damping for a spring rate change:
This
example
problem
applies
the
baseline
Shim
ReStackor
code
to
scale
the
damping
rates
of
the
stock
suspension
to
the
weight
of
a
heavier
rider
and
retunes
the
shim
stack using the
fundamentals
of
spring-mass-damper
theory.
