I'm guessing you set it once and then never fiddled it again (and I can be way off here). The initial setup is just that, a starting point. To get it right you may need to try different combinations of settings to get the most out of any suspension. On my Bobber I increased the preload 3 times after break-in to minimize the sag and then had to back off the rebound damping 4 clicks to allow a faster recovery to full extension. This limited the shock from bottoming out over a rough surface so now it's a very rare occaision (the stock shock bottomed out early and often). With my T-120 I increased the preload twice until the sag was about 20mm and I increased the rebound damping 2 clicks and now it rides how I like it. There's a lot more shock travel on the T-120 vice the Bobber so it's setup is different than my Bobber. With my Thruxton R I have only three available preload settings. Most people don't add preload to their Thruxton's but I had to to accomodate my lard butt in the seat, so it's on the second setting. I also backed off the compression damping 2 clicks and increased the rebound damping 2 clicks. I may adjust that a bit further but right now it's running pretty sweet. I increased the preload on my S3 this last weekend and backed off the rebound damping 2 clicks. It's better but more changes are coming. What I'm getting to is it's adjustable for a reason, keep dialing it in till you have the best performance achievable. It's not a George Foreman Grill where you set it and forget it.
