Yes, you have the understanding of the function of the aftermarket valves. I used a straight rate spring so that the valve will work more efficiently over the stock or progressive spring which for one, the stock is way too soft for my weight and two, the progressive is counter productive to the valves. In my case the ricor's. I chose a mid length pre-load (15mm) and 10wt oil to see how it felt, if I wanted a change I could at this point cut or take out some pre-load or go to a lighter 5wt oil. 5wt is just the suggestion, its thin so it blows through the valve easily one direction and slows the return of the spring the other, dampening it. I wanted a sport bike feel so I used 10wt.
