Input on suspension set up.

[turbowrenchhead]

I'm trying to set up my suspension for mostly trail riding. I do like running the mx pro courses when I have the chance. I have a nice set of stock yfz450's in the front and I had my rear rebuilt by GT speced out to the bike. I took some measurements according to GT's site. What should the numbers be?

 

How to measure ride height:

There are 2 places you need to measure from the bottom of the frame to the
ground (with rider standing on the pegs):
 

1)      

Right at the foot pegs
 

2)      

22 inches forward from foot pegs

To measure ride height - the rider must be standing on the foot
pegs and the measurement needs to be taken from the bottom of the
frame to the ground at the 2 points mentioned above.

How to measure race sag.

 

1.       
Race sag is the amount the quad settles from fully extended
with the rider on board.  First,
put the quad up on a stand,
measure the distance from the axle (vertically) to some point on the
sub frame (make a mark if you need to).

2.       
Take the quad off the stand, put the rider on board standing
on the pegs, have the rider hold onto something for balance, bounce
up and down a little to stabilize the rear end. 
Now again measure the distance from the axle to the point on
the sub frame where you took the measurement in #1.

 

3.       Now deduct the measurement from #2 from the measurement in
#1.  This is your RaceSag.

4.       To adjust Race Sag tighten or loosen the preload adjusting
collars.  If you have
too much race sag, you need more preload, too little race sag you
need less preload.
 

 

My measurements:

 

Race sag 3 1/2 inches

Ride height Peg 9 3/16" Front 9 5/8"

GT wants me to take the preload off and have it set 1 to 2 turns out. Measure the race sag, ride height and spring length.
