when i go sit on it its 1cm
thiss are the measurements with the spring off the 1100 that i putt on it. and its a hole lat better than it was before

do you now the exact measurments off the sag that i need???????

If you go to race tech and do a valving search it will give you the spring rate you need, also on there web site is how to do a sag measurement or you can go to the penske web site download one of the shock manuals and there is the procedure listed there. Basicly what you need to do is pick up the back end and measure from the axle to some fixed point vertically up on the bike with the suspension unloaded, record this dimension then set the bike on the ground gently and measure again this differance is the static sag, then sit on the bike and measure again and the difference is total sag. Looking for about 35mm total sag for street. If you have too much increase the preload on the spring. If you can get the correct total sag but the intial is wrong you have the wrong spring rate for you. Also when you check do an average from both directions this will tell you how much friction is in your linkage repeatable measurements within 2-3mm is good 10mm bad 15mm rebuild the linkage or you over tightened the frame pivot bolt and its binding the swingarm.
