I've been thinking about that too. I haven't done anything yet, but I know that I've got too much sag in it right now.
It's probably a personal preference thing. I plan to tighten mine up in the next few days to see if there's a diff.
If I adjust one, do I have to adjust the other to match? Seems like the front shock would do most of the work when it comes to keeping the track on the ground, and the rear one handles ride comfort.
Am I right?
