heh... not even 80 lbs.  the spring rate is way too low, you'll top
out and bottom out a lot with the 900rr spring.  swap the spring or it
will suck in all sorts of ways.

to get the sag proper with a low spring rate spring (like a 900rr)
you'll need to put lots of pre-load on it.  This works so long as you
never ride the bike.

as soon as you hit a bump the shock will bottom out, because the
spring isn't strong enough.  when uyou come out of a corner the back
end of the bike will bounce way up because the spring force won't fall
off fast enough when it extends.

Here's an analogy:

take two gallon jugs of milk, and two rubber bands, one big fat
thick one, one longer thinner stretchy one.  Tie the ends of the
rubber bands to the handles of the two gallons of milk. (one each)
then lift the milk with the free end of the rubber bands.  

you can lift the one with the thin long band (900rr spring) by holding
the end of the band over your head, but if you lift and raise the free
end (this is like going over bumps and setting the bike into and out
of corners)  the milk doesn't move mutch, you can't really controll it
very well, it kinda just wants to stay at the same height.  This works
really really well if you have 11" of suspension travel, but you
don't, you have 4 inches, so you'll top out and bottom out the shock
all the time.


Now do the same thing with the gallon of milk with the big thick heavy
rubber band.  you don't have to lift your hand so high, and when you
move the free end up and down the gallon of milk follows much more
closely, you can actually control the position of the milk pretty
well.

This is also whey heavier people use heavier springs in the forks and
on the shock.  as you add milk to rubber band you need a heavier
rubber band (spring) to control it well.
