[. . . ] With the correct preload on the spring, with no load on the bike, the forks should come within 3/4" to 1" of returning to full extension after being compressed. Too much sag, add (1) 2mm or 5mm spacer. Note if your fork has a build up or an excess of stiction, complete basic service first before preload adjustment. 3 Tuning continued figure 3 Tuning Your Hydraulic Damper Adjusting the hydraulic damper should only be done after you are completely happy with your spring choice, and the proper spring preload has been set. Your White Brothers UD180 fork comes with the damping adjusted in the middle of its' range. The standard setting is 3 turns out from all the way in (clockwise). Use the following guidelines to determine if further adjustment is needed. SLOWER (cw) FASTER (ccw) A) If your forks rebound too slowly, turn the adjustment screw on the top of the right fork leg all the way counter-clockwise (6 turns out is the maximum)(figure 3). The forks should absorb and return fast enough to absorb the next major obstacle. A sign that your forks are rebounding too slowly is if they feel like they pack-up or continue to compress as you go through rough sections. B) If your forks are rebounding too fast, turn the adjustment screw on the top of the right fork leg clockwise 1/2 turn at a time. If the forks appear to be relatively clean, you can probably go 40 hours between servicing. If the forks appear dirty, you should service them every 20 hours. The three things that will most effect the service interval and performance of your forks is water, mud and dust. Depending on how much time you use your forks in those conditions will determine how much service they require. NOTE: When cleaning the fork, it is not recommended to direct water spray at the seals. NOTE: Neglecting proper fork maintenance will reduce the forks life. Internal build up of water and dirt, or a lack of lubrication will cause excessive wear to the forks. In harsh condition it is advisable to inspect the forks for dirt ingestion after each ride. Basic service should include disassembly the forks, cleaning and re-greasing all shafts and seals. At this time, the forks should be carefully inspected for wear and damage before reassembly. NOTE: Disassembly of the hydraulic damper should be left for a dealer who is familiar with servicing the WB forks hydraulic damper. * White Brothers recommends that you consult with a qualified technician before performing the following: Basic Fork Disassembly 1) Disconnect from brake caliper. Remove wheel assembly by loosening fork axle seat pinch bolts loosening and removing front axle.
