Sonic springs gives you a long tube of PVC pipe to make the spacer. Cut the spacer to length and clean up the edges to prevent loose pieces of PVC from floating around.

Step 18: Add fork oil and bleed. This is done without the GVE or spring or anything else (other than the damper rod) in the fork tube. Add enough oil that when the fork is completely extended the oil still covers the inner tube. Pump the fork up and down a while until you hear (and see) no more air coming out. Not too complicated.

Step 19: Assembly and setting the fork oil level. As gently as possible so as to minimize a big splash of fork oil, drop the GVE down into the fork tube. Fully compress the fork. Measure from the top of the fork the distance to the fork oil. This is the important thing: the fork oil level. Racetech recommends 130mm of fork oil. Sonic Springs (and others on this website) suggest 115mm. 125mm was chosen by our rider. Remember to take your time. Set up a jig or something to hold the fork upright at this point so you don't spill fork oil.

Step 20: Install the fork springs, then a washer, then the spacer, then another washer. Place the fork cap back on. If everything is done correctly, the cap will be 1/2" (preload setting) above the ring. So, you'll have to compress the spring to get the circle/ring clip (or [[How do I remove the fork caps/pistons?|new circlip]]) back on:
