Next, Matt cut the spacers for each fork. The length of spacer needed for each fork was 3 1/2 inches from the washer sitting on top of the new spring to the top of the fork tube. He then cut two 3 1/2-inch spacers and removed the springs to install the fork oil. He collapsed the slider, then poured the oil in, pumped the slider up and down to suck out the air bubbles, then he used a fluid evacuating tool to get the correct amount of fork oil. Oil level measured 6.3 inches from top of fork tube (level varies depending on model). Lastly, he re-installed the spring, washer, spacer, final washer, and capped off each fork leg.
