Ok, so here is my first attempt at a small DIY.
Adjusting the preload isn't a really big deal, but if you've never worked on a bike before, it can be a little bit daunting! Since I was going to do it anyway, I figured I would take pictures and post it up here.
After having the chance to ride another forum member's bike, I realized just how mushy mine felt. Knowing that he'd adjusted his, I decided to give it a try with mine, and I like it much better now! The suspension is stiffer, and it's not as much the feeling that I'm turning in pudding or something...
So, to adjust your rear shock preload:
1. You need this thing out of your tool kit that came with the bike:
2. I reached in from the right side, preferring to avoid removing the chain guard and the grease on the chain if at all possible... I placed the spanner as far around as I could, and pulled:
it takes a little effort, so I used both hands:
3. And now it's on the second notch
That's all there is to it - rather simple really!
