A month ago I bought some new suspension for my '98 ST1100. Progressive 465 rear, and Progressive springs up front. I needed new seals and bushings, so just did the rear myself, and dropped it off at a dealer for the springs. I didn't ride it much since then (other bikes) but these springs are way too soft. I haven't measured, but I suspect the weight of the bike uses half of the travel. Is it relatively simple to add spacers? The new springs also squeak like crazy, is this normal?
