To make it easier for some of you, try not to worry so much about the science. Just do the mechanics of it. Turn the spring collars downwards till you get to the ride height desired! jack up the car, turn the collars are few turns, and get in the car. Do it till your at a hieght that makes you happy!. Front should sit a bit taller than the rear, this will put more leverage on the rear for improving traction and control.
run the front crossovers all the way up to the collars so to soften the ride a bit with the stock springs. If your car is loaded, you don’t have a lot of threads in the front with the shorter top springs, but should be enough. You can also add nitrogen pressure that will raise the ride height also. It will firm up the ride some, so you can back the dial out a bit. It will firm the sway characteristics also as the shocks only have about 100 to 110 psi stock. The stock Foxes have a bit ridiculously firm valving, There is so so much room to make the KX ride smoother!
my Kx set ups are getting out and about!! Find one and get a ride!
have fun! Moto!
