I've got a set of 39mm narrow glide forks on my shovel. It dives like a mother! I added race fork oil but it still dives too much. I know some people have preloaded their forks with pvc. What size pvc did you use? How large or a spacer did you use? I'm assuming you added a washer between the pvc and the top spring. Any tricks on getting the cap back on with the newly preloaded fork?
