***Will not lower the 2012-13 models as the stock links are approx. the same length as ours.
2) Raise the motorcycle with a bike stand, milk crate, etc., so the rear wheel is just slightly off the ground. Remove the nut (left side) from the forward link mounting bolt and push it out the right 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 and push it out. Both links should now be off the bike. Push the stock 19 mm steel bushings out of the stock links and install them back in the new Koubalinks. ***You will have to tap the 4 bushings out of the stock links using a 19 mm OD punch, then install them into the new links the same way or by using a vice or press.
3) After Installing the KoubaLinks, (engraving to the outside and readable from the right side) the left link engraving will read backwards, as 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 ft. lbs.
4) After the links are installed, reset the race sag. If the links are for lowering purposes ONLY, sag can be set at 3.90", and will lower the rear of the bike 1 to 1 3/8th inches depending on the model and axle adjustment. If the best performance is desired we recommend a race sag setting of 3.25 to 3.50 inches.
* Less rear sag = quicker steering less stability. More sag = slower steering more stability. The easiest way we have found to adjust the rear spring preload/sag, 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, 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 top 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 1/16" 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.
