Installation
Instructions
Fits: Gas Gas 2001-up 200/250/300/450FSE
Lowers the rear 1 to 1 3/8th inches depending
on the model.

1) Before removing the OEM
links, take a race sag measurement (amount of vertical movement
of
the rear axle FROM no weight to bike weight plus rider weight) with rider
in full riding
gear,
standing on the pegs. The race sag recommended by Gas Gas is 100 mm's (3.9
inches)
and
if the same sag is used with the KoubaLinks they will lower the rear 1
to 1 3/8 inches
depending
on the model. These longer links put more leverage on the rear spring,
so
bear
in mind the race sag may need to be reset after the longer Koubalinks are
installed.
Our
recommended race sag with the new links is 3.25 to 3.5 inches for the best
performance.
With
our sag recommendations, the rear will not be lowered the full amounts,
but will ride
smoother
on the small stuff and have more travel remaining.
2) Raise the motorcycle
with a bike stand, milk crate, etc., so the rear wheel is just slightly
off
the
ground. Remove the nut (left side) from the forward link mounting
bolt and push it out
the
right side. *You may need to raise the swing arm slightly so the bolt will
slide out freely.
Then
remove the nut off the rear link mounting bolt and push it out. Both
links should now be
off
the bike. Push the stock 19 mm steel bushings out of the stock links and
install them back in
the
new Koubalinks. ***You will have to tap the 4 bushings out of the
stock links using a 19 mm
OD
punch, then install them into the new links the same way or by using a
vice or press.
3) After Installing the
KoubaLinks, (engraving to the outside and readable from the right side)
the
left link engraving will read backwards, as both links are identical. Install
the new links
in
the reverse order of the removal and torque the link mounting bolt nuts
to approx. 40 ft. lbs.
4) After the links are
installed, reset the race sag. If the links are for lowering purposes
ONLY,
sag
can be set at 3.90", and will lower the rear of the bike 1 to 1 3/8th inches
depending on the
model
and axle adjustment. If the best performance is desired we recommend a
race sag
setting
of 3.25 to 3.50 inches.
* Less
rear sag = quicker steering less stability. More sag = slower steering
more stability. The
easiest
way we have found to adjust the rear spring preload/sag, is to use a long
punch (we
use
a piece of 1/4" X 12" steel keyway stock, rounded on one end) to loosen
the top jam nut,
then
grasp the spring at the bottom and turn the spring and the preload nut
at the same time.
Turning
the spring/nut clockwise increases the preload and decreases the sag.
Do not forget
to
tighten the top jam nut with the punch after setting the sag.
5) The front forks can
be slid up in the triple clamps until they almost contact the handlebars,
which
is a good starting point with the lowering links. Headshake or turns
too quickly?
Move
them back down a little, like 1/16" at a time until handling is acceptable.
Disclaimer:
Sliding
the tubes "up" farther can allow the tire to hit the fender and could lock
up the
front
wheel, so be careful out there.
