I have a presumably stock '00 XR600R. This morning I decided to install my new Race Tech FRSP 3750-46 (.46 kg) fork springs. When I took the original springs out, there was no preload spacer in the fork tubes, and the stock springs free length was 7/8" shorter than the required set length. In other words, with the fork cap unscrewed from the fork tube, but still connected to the damper rod, I had .875" of free play (slop) for the spring to bang around. I've done a few forks in my time, but I've never seen a "free floating" spring inside a fork before. Now get this, my heavier weight Race Tech springs are 3.875" shorter than the stock fork springs. I needed to install a 4.750" long spacer between the spring and fork cap just to eliminate the empty gap. I also wanted to add 1.250" additional length to the preload spacer to firm up the ride a little. So I ended up using a 5.750" piece of PVC pipe plus two .125" thick washers. Am I just naive, or is it okay for fork springs to bang around inside the forks without a spacer for compression? And by the way, I'm gonna have to cut about an inch off my spacers. I went riding today and beat myself senseless with a set way way too stiff forks.
