Raise the motorcycle with a bike stand, milk crate, etc., so the rear wheel
is just slightly off the ground. If your bike has the factory sidestand
it must be taken off by removing the 2 Allen headed bolts. Remove
the two 17 mm nuts from the link mounting bolts that hold the stock “H”
link to the rocker and the engine cradle. Push both mounting bolts
out the left side. (The front mounting bolt has the chain roller attached
but can be left on the end of the mounting bolt) *The swing arm may need
to be raised slightly to allow the first bolt to slide out freely.
The new links come with only the bearings and seals, so install the center
from your OEM
into the new KoubaLink. Install the new link on the bike (bearing end forward)
with the grease fitting facing down and towards the rear by pushing the
front mounting bolt (the one with the chain roller on the end) in from
the left side. You may have to raise the swing arm slightly to allow
the center of the bearing end to move back enough to allow the bolt to
align with the center of the bearing sleeve. Next install the fork
end mounting bolt. You will have to raise the swingarm to install
the fork end mounting bolt. *Left link engraving will be upside down
and backwards, right side will be readable left to right. You need
to pump some grease in now as sometimes tightening the mounting bolt nuts
can seal the bearings too tight to allow the air to escape. Install
the 17 mm nuts on the mounting bolts and torque to 35 lbs-ft.
If the link is used for lowering purposes only we recommend the rear race
sag be set at approx. 4.0" and you will get the amount of laden rear lowering
claimed for that link. You can run less rear sag for a better ride
but that does take away from the laden lowering amounts. If you need
to reset the rear race sag 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
turn the spring and the preload 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 after setting the
You can slide the fork tubes up approx. 3/4" from the stock position (our
bike had the fork tubes set at the 2nd index line) by loosening the pinch
bolts on the triple clamps. How much you need to slide them up will
depend on the amount of rear race sag. Just keep in mind that lowering
the rear more than the front slows the steering but makes it more stable
on the striats and visa versa. However much you change the fork tubes,
be sure they are both set at the same position and that the triple clamp
pinch bolts are torqued. *Do not over torque the triple clamp bolts.
(TM recommends 11.0 ft. lbs. for the lower clamps and 14.0 ft.lbs for the
uppers.) Sliding the fork tubes up farther than 3/4"could allow the
tire to hit the fender if the forks are bottomed. :-(
Raising or lowering the rear more than the front can change the geometry
and could affect the handling, so be careful out there.
