Just came across the below blurb about setting up the WP forks. I'm hoping to make the same change in the future and thought it may interesting to someone...I've put the interesting bit in Bold and italic typeface.



WP FORK SETTINGS
For hardcore racing, we ran this setup on the 2012 KTM 250SX (stock specs are in parentheses).
Spring rate: 0.46 kg/mm
Oil height: 370cc (380cc)
Compression: 7 clicks out (12 out)
Rebound: 12 clicks out
Fork-leg height: 5mm up (flush on a sandy track)
Notes: The cheapest way to fine-tune the KTM’s WP forks is to raise and lower the fork-oil height to get the smoothest midstroke action without bottoming, which is why we lowered the oil height by 10cc. KTM’s forks come with different oil heights for each model. The 125SX and 150SX have their oil set at 360cc, the 250SX has 380cc, and the four-strokes roll out of the factory with 390cc.

WP SHOCK SETTINGS
For hardcore racing, we ran this setup on the 2013 KTM 250SX (stock specs are in parentheses).
Spring rate: 5.4 kg/mm
Race sag: 105mm
Hi-compression: 2 turns out
Lo-compression: 15 clicks out
Rebound: 12 clicks out
Notes: We ran a 1.25mm-longer Pro Circuit shock linkage. Not only did it lower the rear of the bike by 10mm, but it stiffened up the initial part of the shock’s stroke to help widen the range of the stock 5.4 shock spring. Faster or heavier riders might be required to go to the stiffer 5.7 kg/mm shock spring. If you are savvy, you will use free sag to make the decision for you.
