the HRC stiffer springs are much more progressive than the stock set. They start at a lower rate and end at a higher rate. This makes it real nice, as your preload actually adusts the rate. The more preload, the higher range in the progression the forks sit. Basically, you can use these springs for lighter and heavier riders.
The VTR springs are almost identical rates as the HRC ones, if I remember right.
If you dont like the Gold Valves, I also have the shimstack info from the stock RS250 89-90 conventional forks like our NSR's use. You can use this shimstack info with your stock valves. With the Gold Valves, you are most likely still going to have to shuffle the shims to find the best performance.
