                  Installation Instructions
       Kawasaki 04 KX250, 04-05 KX250F & 04-06 Suzuki RMZ250
                Lowers the KX250 rear 1.375" & 1.25" on the KXF/RMZ250
                      *Will not work on the 05-up KX250 Two Stroke.
 

1)   Raise the motorcycle with a bike stand, milk crate, etc., so the rear wheel is at least 2 
      inches off  the ground.  Remove the two 19mm nuts that hold the “H” link to the rocker
      and the engine cradle and push the bolts out.  (The lower chain roller needs to be 
      remove from the frame on the KX250 to get access to the front mounting bolt nut. The 
      lower chain roller on the four strokes also needs to be removed from the mounting bolt
      as it will not clear the footpeg pin when left on the end of the bolt.)  Remove the front 
      mounting bolt first on all models to allow the rocker to move with the swingarm so the 
      head of the rear mounting bolt will clear the chain buffer. **If you have  the Promoto 
      Billet side stand, it must be removed before the front bolt on the four strokes can be
      removed.

2)   The new links come with the bearings and seals, so install the center sleeve and the two
      step washers (flat side out) from your OEM link into the new link and install it on the bike
      by pushing the mounting bolts in from the left side, rear bolt first. **Front mounting bolt 
      on the KX250 two stroke comes in from the right side.  Install the outer washer/nut and 
      torque to 38 lb-ft. 

3)   When installing the KoubaLink, be sure the 90 degree grease fitting is facing down. *Left 
      link engraving will be upside down and backwards.

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. Then slide the fork tubes up until they barely clear the bottom of 
      the stock bars. ** Do not over tighten the triple clamp pinch bolts.  (14 ft- lbs. on the lower
      bolts, 17 ft-lbs on the upper bolts)  If the links are for lowering purposes ONLY, sag can be
      set at 100mm/ 3.90", and will lower the rear of the KX250 1.375" and 1.25"on the KXF-250 
      and RMZ-250F. The easiest way we have found to adjust the rear spring preload is to use
      a long punch to loosen the top preload/jam nut from the right side and grasp the spring 
      at the bottom and turn the spring and the preload nut at the same time. **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 with the punch after setting the sag.

5)  The front forks can be slid up in the triple clamps approx. .375 inches until they contact the
     handlebars. For additional lowering of the front, the bars can be spaced up by installing a
     washer of 1/4" max thickness on top of the flanged washer above the top rubber handle bar
     mount on both sides. This will allow the the forks to be slide up farther but is not 
     recommended unless you require quicker stearing. Disclaimer:  Lowering the rear more 
     than the front can change the geometry and could affect the handling, so be careful out 
     there.
