Raise the motorcycle with a bike stand, milk crate, etc., so the rear wheel
is just slightly off the ground. Remove the two 17 mm nuts from the
bolts that hold the stock link to the rocker and engine cradle.
Push the bolts out the right side/front mounting bolt first. The
swing arm may need to be raised slightly to allow the first bolt to slide
The new links come with only the bearings and seals, so be sure to remove
and install the two piece center sleeves from your old OEM link into the
bearing end of the new Koubalink. Install the new link on the bike
(grease fitting facing down) by pushing the mounting bolts in from the
right side. *Front mounting bolt is the longest. You will have
to raise the swing arm to align the second set of holes. Be sure
the 90 degree grease fitting is facing down. **Left link engraving will
be backwards, right side will be readable left to right. Grease the fitting
now as sometimes tightening the mounting bolt nuts can seal the bearings
too tight to allow the air to escape when pumping the grease in.
Install the two 17 mm nuts on the mounting bolts and torque to 35 lbs-ft.
For the best performance, set the race sag (amount of vertical movement
of the rear axle FROM no weight to bike weight plus rider weight) at 3.25"-3.50"
with rider in full riding gear, standing on the pegs. Loosen the
triple clamp pinch bolts and slide the fork tubes up until they barely
clear the bottom of the stock bars. *Do not over torque the triple
clamp bolts. (14 ft. lbs. lower, 17 ft. lbs. upper) If
the link is used for lowering purposes ONLY, rear race sag can be set at
100mm/ 3.90" and will lower the rear approx. 1 ” with the HL8-1 link and
approx. 1 ½” with the HL8-2 link. ***The HL8-2 link may require
some filing on the swing arm tunnel or the shock’s spring and retainer
for clearance when the swing arm is fully extended. (Please have
a look at the picture below.) The easiest way we have found to adjust
the rear spring preload is to use a long punch to loosen the top jam nut
and grasp the spring from the right side just above the swing arm and turn
the spring and the top adjusting nut at the same time. ** You may
have to put some lube on the shock threads to allow the nut to turn freely.
Turning the spring/nut "clockwise" increases the preload and decreases
the sag. **Do not forget to tighten the jam nut with the punch after
setting the sag.
Lowering the rear more than the front can change the geometry and could
affect the handling, so be careful out there.
