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 off the
bolts that hold the link to the rocker and the engine cradle, push the
front bolt out the right side first. The swing arm may need to be raised
slightly to allow the bolt to slide out. Next remove the rear mounting
bolt out the left side. (Chain buffer may need to be pulled down
or removed on the bottom to allow the bolt head to pass by.) The
link should now drop out the bottom.
2) The new link
comes with new bearings and inner sleeves so be sure the sleeves are inside
the KoubaLink and that none of the needle bearings have fallen out in transit
and are laying loose in the plastic bag. If you find any of the needle
bearings have fallen out, reinstall them in the bearings with a bit of
grease and you should be good to go as long as all four bearings have a
full compliment of needles. Put the four outer seals from the stock
link onto the new link and your ready to install the KoubaLink on the bike.
**Note: The earlier XR650L KoubaLinks did not come with the inner
sleeves so if you have one of those be sure to use the sleeves from your
stock link in the KoubaLink.
the new link by holding it up inside the front and rear mounting brackets
on the bike (grease fittings facing down/engraving readable from the right)
and push the rear mounting bolt in from the left side first, then push
the front bolt in from the right side after aligning the mounting eye with
the front brackets. You will have to raise the rear wheel to align
these eyes. Install the two 17 mm mounting bolt nuts, and torque
to approx. 35 lb-ft. You may want to pump a little grease into the
two grease fittings at his point.
4) 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 3.5" with rider
in full riding gear, standing on the pegs. If the links are for lowering
purposes ONLY, sag can be set at 100mm/3.90", and will lower the rear of
the bike 1.750" on all the XR650L's. and near that on all other models.
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 at the
bottom and turn the spring and the preload nut at the same time.
**You may have too 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.
the eight (four per leg) 12 mm headed pinch bolts on the triple clamps
and slide the fork tubes up until they are even with the bottom of the
handlebars. There should be about 1" showing from the top of the
fork cap flange down to the top of the top triple clamp) Torque the triple
clamp pinch bolts to 15 lb-ft. *Disclaimer: Lowering
the rear more than the front can change the geometry and could affect the
handling, also sliding the fork tubes up too far will allow the tire to
contact the fender/triple clamp on full compression, so be careful out
