how do you adjust the shocks? i want softer in the front and firmer in the rear.

z400 has 8.5" of travel in front, and 9.1" in the rear

free sag
this first measurement determines how much free sag your suspension has. free sag is the amount of suspension travel that is used when the auazd is under its own weight subtracted from the overall suspension travel. don't worry, it sounds more technical and tough than it is. dettermining these measurements for the front and rear suspension require two different methods:
front suspension: have a friend lift the front end of the quad until the a-arms are fully extended but the tires are still in contact with the ground. take a measurement from the floor to a center point on the front of the quad's frame. (mark the point with a marker because you must use that as a point of reference for future measurements) this is called the "unloaded measurement"
Once this measurement has been taken, put the unit back on the ground and bounce the front suspension to let it settle in. now measure from the ground to the same point on the frame. subtract the weighted measurement (the second measurement_ from the unloaded measurement (the first measurement) to obtain your free sag value. ideally, the number you get after doing the math should be around 10% of your quad's total suspension travel (ex: 1 inch of sag for 10 inches of total suspension travel)

i'm sick of writing all of it so now i'm putting up just the main points.

rider sag:
this is more important than the free sag. it is the measure of how much of the total suspension travel is used when a fully geared rider is sitting in normal riding position. it should be somewhere around 30% of total suspension travel of your quad (ex: 3 inches of sag for 9 inches of total suspension travel)
measure from grabbar to center of the swingarm and record. for the front measure from marked point on frame to ground just like you did for the free sag.
subtract the rider sag from the unloaded suspension measuremnets that you took when you did the free sag measurement. again it should be 30%

shock adjustments
compression: its speed sensitive and controls the shock over g-outs, whoops and jumps. turning clockwise makes harder/
rebound: controls speed of the shock as the spring pushes the shock shaft back out to its original psotition after being compressed.. it helps "fight" the spring in order to have a controlled spring return. mostly used in whoops, if you are going faster you need the rebound set faster. because if its not set fast enough the shocks will be completely compressed and won't absorb anything which will make it rough. to make rebound faster turn clockwise.
