1) Raise the motorcycle with
a bike stand, milk crate, etc., so the rear wheel is slightly off the ground.
Remove the brake pedal return spring and the pinch bolt holding the brake
pedal pivot shaft into frame mount. Then remove the brake pedal to allow
the front link mounting bolt to come out the right side. Remove the
17 mm nuts from the two link mounting bolts (14 mm heads) and push the
front one out the right side and the rear one out the left 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 KoubaLink.
2) The KoubaLink comes with
the bearings and seals, so put a little grease inside the two needle bearings
first, and then install the "center sleeve" from your old OEM link into
the new link. Be sure the center sleeve from your stock link is clean
and greased the full length. 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. You will need to raise
the swingarm to get the eyes to line up. Front bolt goes in from
the right side and the rear bolt goes in from the left side.
3) After installing the KoubaLink,
be sure the grease fitting is facing back and slightly down. *Left side
engraving will be upside down. You may want to pump a little grease
into that 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 17 mm nuts
and torque to approx. 35 lb-ft. *NOTE: Always loosen and tighten
the nut, and not the head of the bolt.
4) For the 1.75" laden rear
lowering, set the "race sag" (amount of vertical movement of the rear axle
FROM no weight to bike weight plus rider weight) at 3.0" 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 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 under side
of the handle bars. We do not recommend over 3/4" of the fork tubes
showing above the top triple clamp not counting the thickness of the fork
caps. If the front pushes or will not turn quick enough we
recommend lessening the rear sag rather than sliding the fork tubes up
farther than the 3/4" showing.
Disclaimer: Lowering the rear
more than the front can change the geometry and could affect the handling,
so be careful out there.
