**03 KX250 requires 2 mm flat washers on each end of the mounting
                                                 bolts to allow  for tightening.  (Stock links are 2 mm's thicker) 

2) Raise the motorcycle with a bike stand, milk crate, etc., so the rear wheel is just slightly off
    the ground.  Remove the 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 and push it out.  Both links will now be 
    off and your 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
    on most year models.

3) When 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. 
    50 lbs-ft.

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 approx. 1 inch depending 
    on the year model and axle adjustment. If the best performance is desired we recommend 
    a race sag setting of  3.00 to 3.50 inches, depending on how quick the stearing is desired.
    * Less sag = quicker stearing less stability. More sag = slower stearing 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
    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 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.
