sag adjustment and rear spring stiffnes

as a beginner i got help in yamaha Forum and every body suggesting me to adjust my sag properly . i have done it but i never could get more than 60mm(2.3inch) !?? 

last week i just looked at my rear spring stiffness and i underestand it is 60Nm which is for some one much heavier than me , i am 187lbs(85kg) . 

i wanna order a softer spring  but i dont know how much softer i should get !? i am thinking to get a spring with stiffness around 52 !? do you think its ok or i should go up or maybe down to 50Nm !? 

And if i order a shock with 52Nm from öhlins is it the same as 52Nm from twenty , or it can vary from different manufactures.

Call Factory Connection or email them. They will give you recommended based on body weight. Just installed my springs front and rear for my 200lbs, set my preload and I have 100mm race sag naked, and 105mm race sag in gear. Perfect.
