                       Installation Instructions
                             Fits: 1990-1999 Suzuki DR250/350/S/SE.
                                                  (Links #1, 2, & 3.)

1. Raise the motorcycle with a bike stand, milk crate, etc., so the rear wheel is just slightly off the ground.  Remove the two 19 mm nuts that hold the links to the rocker and the swingarm, and push the bolts out the left side.  Sometimes the swingarm needs to be raised to allow the bolt head on the swingarm end to clear the chain, so remove the bolt from the rocker end first and the swingarm end second.

2. When installing the Kouba links everything is in the reverse order of the removal of the stock links. On the swingarm end you should have a steel flat washer, then the aluminum spacer washer (included with the Kouba Links) and then the new links with the engraving to the outside and readable. Torque the mounting bolt nuts to between 60-87 ft-lbs.

3. For the best ride set the sag (amount of vertical movement of the rear axle FROM 
no weight TO bike weight plus rider weight) at 2.5" inches with all the lengths of the DR350 KoubaLinks, with rider in full riding gear, standing on the pegs.  If the links are for lowering purposes ONLY, sag is set at 3.75", and will lower the rear of the bike approx. 2.0" with the DR #3 links, 1.75” with the DR #2 links and 1.5" with the DR #1 links.  The front forks can be slid up in the triple clamps until they contact the handlebars.  For additional lowering of the front, a second set of the top halves of the handlebar clamps can be installed under the bars and tightened with 3/4" longer bolts. That will allow the forks to be slid up an additional 3/4", but is not recommend as the tire could hit the fender when fully compressed if they are slid up too far. 
Disclaimer: Lowering the rear more than the front and visa versa will change the geometry and could affect handling, so be careful out there.

4. For the stock DR and DRS shock, set the compression clicker/adjustor (on the canister) to 1/2 turn in from full soft. On the DR dirt only model and the 98 and 99 DRS model, set the rebound clicker at 1/2 turn out from full hard. (No rebound clicker on the pre 98 "S" models.) If bottoming is a problem, try turning the compression adjuster in/hard. If that is not enough, a stiffer spring may be required.

*These setting are just a starting point and may not be the best for everyone, so
  experiment with them and find the best settings for you and the conditions.
