1) Raise the motorcycle
with a bike stand, milk crate, etc., so the rear wheel is slightly off
the ground. Remove the 17 mm nuts from the two link mounting bolts
and push the bolts out the right side. The swingarm may need to be
raised slightly to allow the bolts to slide out freely. After removing
these two bolts the link will drop out the bottom and your about ready
to install the new link.
2) The new links come
with the bearings and seals, so put a little grease on the two needle bearings
first, and then install the "center sleeve"
from your old OEM link into the KoubaLink. You are now ready to install
the new link by holding it back in place with the bearing end forward and
the engraving readable from the right side. After aligning the link
eyes with the link mounts, push the mounting bolts back through from the
right side. You will need to raise the swingarm to get the eyes to line
3) After installing the KoubaLink,
be sure the grease fitting is facing downward. *Left side engraving will
be upsidedown. You may want to pump a little grease into the grease
fitting now before you torque the mounting bolt nuts as sometimes after
tightening the nuts the air will not escape from the bearings and is difficult
to get the grease in. Install the two 17 mm nuts and
torque to approx. 35 lb-ft.
4) For the 1.75" rear lowering,
set the race sag (amount of vertical movement of the rear axle FROM no
weight to bike weight plus rider weight) at 3.75" with rider in full riding
gear, standing on the pegs. This sag adjustment can be changed by
turning the two large nuts on top of the rear spring. (More preload
= less sag, and less preload = more sag. Turning the spring preload nuts
clockwise will increase the preload/ lessen the sag and visa versa.)
The easiest way we have found to change the preload adjustment is to loosen
the top jam nut, lube the threads on the shock and turn the spring and
all by grasping the bottom of the spring. It will turn easier if
the rear wheel is off the ground.
5) The front fork tubes can
be slid up in the triple clamps until they almost touch the stock handlebars,
we do not recommend going farther than the stock height handlebars allow
as we are not sure exactly when the front tire would be allowed to
contact the underside of the fender when fully compressed. :-(
If the front pushes or will not turn quick enough we recommend lessening
the rear sag rather than sliding the fork tubes up farther.
Disclaimer: Lowering the rear more than the front can change the
geometry and could affect the handling, so be careful out there.
