Mike, don't be afraid to turn the clickers, that's what they're for. Check out Jer's tuning guide at
www.mxtech.com It will give you good direction on what does what. Just take note of where you started, if you make it worse, just put it back to those baseline settings (original postion).
As for respring and revalve...the spring holds you up, the valving controls the damping (controlling the movement). Your manual will show you how to set sag, and how to determine if you need stiffer of lighter springs from that setting.
The valving controls the movement of suspension (basically it keeps it from bouncing like a rubber ball). Many revalve their suspension to meet their specific needs, weight and terrain. This is kind of a "fine tuning" deal. I think you would be well served to experiment with the clickers. If you can't get what you want with the clickers, then it's time to revalve.
Keep reading posts on this forum, there is a wealth of info hear....lots to learn! This is a GREAT place to learn!
