1) Before removing
the OEM links, take a race sag measurement (amount of vertical movement
of the rear axle FROM no weight to bike weight plus rider weight) with
rider in full riding gear, standing on the pegs. The race sag recommended
2) Raise the motorcycle with a bike stand, milk crate, etc., so the rear wheel is just slightly off the ground. Remove the 17mm nut (right side) from the forward link mounting bolt and push it out the left side. *You may need to raise the swing arm slightly so the bolt will slide out freely. Then remove the nut off the rear link mounting bolt (left side) and push it out the right side. Both links will now be off and you are ready to install the KoubaLinks. Some bikes have both the link mounting bolts installed from the same side and can see no reason they cannot be installed from either side.
3) When installing the KoubaLinks, the engraving should be to the outside and readable from either side. (Both links are identical.) Install the new links in the reverse order of the removal and torque the link mounting bolt nuts to approx. 40 lbs-ft. **You will have to raise the swingarm to line up the mounting holes.
4) After the links are installed, reset the race sag. If the links are for lowering purposes ONLY, sag can be set at 3.50", and will lower the rear of the bike approx. 1 inch with the KX100-1 links and 1 3/4 inches with the KX100-2 links. If the best performance is desired, we recommend a race sag setting of 2.75" to 3.25" depending on the conditions and the setup The easiest way we have found to adjust the rear spring preload is to use a long punch (we use a piece of 1/4" X 12" steel keyway stock, rounded on one end) to loosen the top jam nut from the right side, then grasp the spring at the bottom and turn the spring and the preload nut at the same time. 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.
5) The front forks can be slid up in the triple clamps until they almost contact the handlebars, which is a good starting point with the lowering links. Headshake or turns too quickly? Move them back down a little, like 1/8" at a time until handling is acceptable. Disclaimer: Sliding the tubes "up" farther can allow the tire to hit the fender and could lock up the front wheel, so be careful out there.
