I took a peek at Guzziology this morning and Dave simply says that a piece of 1.5" ABS plumbing pipe can be used as a pre-load for insuffient spring rates. No indication of where to place. There is a diagram showing dimensions of this spacer. It shows 1" diameter and 1.5" tall with a narrower (0.59") diameter at top of the diagram. I'm not sure how to interpret this. I hope more people check in on what they've done in this regard, especially the dimensions and placement (top or bottom of spring). Also, someone once mentioned that with a set of new Wirth progessive wound springs, no pre-load was necessary. This right? Ray

As far as where to put the pvc spacer- it HAS to go on top. 1 1/2" > pvc will not set flat on the castellated nut at the bottom of the spring housing. It'll be obvious to anyone who tries it out.
Huh! My memory is failing me. I'm sure I put mine on the bottom. I used
a 1 1/2" inline coupler/splice unit that I cut 1/2" off each end. It's probably 1 3/4" od.
