O.k. now pay attention to the torque spec, it's not particularly tight
 so don't overdo it.  You actually want some ability for the fork to
 shift so if you bang the bike up it won't bend or break the forks,
 they'll just shift a bit.
 
 When you torque the bolts, keep rotating around them as when you
 tighten one, the other will loosen.  Took a good four rotations to get
 them all evenly snugged down for mine.
 
 My stem was very very loose when I got my bike used, snugging that
 down helped as well.  Now there's a nice even, light bit of drag on
 the bars turning.  Before I adjusted it, it would flop under its own
 weight from side to side.  Had quite a lot of slop to it.

There's a formula for sag on a dirtbike, Devon helped me with that, he
 knew it off the top of his head.  Google will find it for you, there
 are numerous articles explaining how you measure it.  It's helpful to
 have an assistant in doing so as you measure the height with and
 without you sitting on the bike.

What I did was replace the stock shock spring with a 500-560 LR
 Progressive.  I'd already bought it or after I did some reading would
 have just gone with a 500lb or so straight rate spring.  At any rate,
 the spring really helped.  The added spring kept my rear from dropping
 so far and thereby lightening the front end...which in turn makes it
 feel too light and skittish on the road.
 
 I also went to the LR Progressive fork springs and cut one of the
 stock spacers directly in the middle and used the halves as preload
 spacers.  Major difference in feel as well as being right on the money
 for my weight for preload height.
 
 One more thing to check carefully is your rear axle adjustment and
 alignment.  Measure from the swingarm pivot bolt center to the center
 of the axle on both sides.  It should be equal.
 
 If the rear of the bike is out of whack in any number of ways, the
 feel of it can manifest itself as though there is something off with
 the front of the bike.  It's all a sort of delicate balance and is
 amazing the difference even small changes can make.
