Another thread on here asked for the same thing.
Surely someone that deals these clutches can post this info online or at least in this forum for all to see.
A nice reference chart like Bully offers would be much appreciated.
Give Mike Curry a call, or the dealer for the brand that you are running. There are so many names and colors that these clutches go by - all come out of the same little shop in central Illinois.
I have a nice little chart for the .085" wire Gold Surge Spring....really need to take the time to make one for the Standard spring since no one else has in the last 15 years
My buddy Brian Barnes over at Pulse clutches has provided me with a new Silver (actually silver dichromate I think) spring that they are using in their new mini clutch that works a smidge better than the Stock OC spring. He is currently dynoing a clutch with the three main Viper levers available and creating a height chart for it. Should work for both springs to get the average guy in the ballpark on his workbench.
