SRX Bender Clutchin

[heinz18h]

Does anyone know the spring rates of the yellow with blue stripe Bender spring that came with my clutch kit? It is a short spring with a 8mm spacer. I have a 47/43 bender helix, green secondary spring at 80 degrees, and stock weights. Would like to know what color factory yamaha spring would work best with this setup?

Just wondering if anybody has any ideas of what spring would work best with this setup. Looked at all the setups in the tech section, and did multiple searches and have not seen any setups like mine. Anybody have a suggestion on what factory spring to use with this, was leaning towards a www yamaha spring, is that the right direction to go. Don't have access to multiple springs to try so any help appreciated.
