yup setup all the controls to suit you. as for prelaod it depends on your weight whether or not your going to actually get it within the ball park. so lets start with how heavy you are....

the complication of a miss matched spring preload to match a rider is you will either top out or bottom out the suspension travel with the rider off the bike.

i'll try to explain this. lets say you have springs on the bike that are suited to an 8st rider and you are 11st, more commonly people will wind the preload up till they can get as near to the recommended "sag settings" as they can. the problem with this is that you will "top out" the suspension when the rider gets off the bike. the bike needs "give" in the form of "bike sag" for the dampers to function properly. call it "negative suspension travel" and its purpose is to allow for slow chassis movement like braking and acceleration. lets say you are hard on the brakes and the rear of the bike lifts, with a "topped out" preload the rear wheel will lift off the ground a loooot easier than a bike with the proper "bike sag". with the rear wheel now off the ground you have diminished your braking performance as well as upset the chassis so more inclined to crash if you hit a bump.

if you haven't worked it out yet, its worse to set up suspension if its going to remove bike sag. so you set your bike up for bike sag only and wherever the suspension falls with the rider on it is better than topping out with an over preloaded spring. however if the rider is wayyyyyy over the recommended then its time for new springs or a different bike.
