Well my fz07 boosted build is near completion. Last order of business to solve is my clutch slipping. So originally I was running 6lbs of boost on stock engine on pump 93 octane and ebc 10%-15% stiffer did the trick, but now I'm on a built motor on e85 it made 132 rear wheel hp on 9psi and that is as much as I could turn it up without slip. I'm thinking there's gotta be some stiffer springs from another bike that would work. If anybody had access to measure maybe some fz09 springs or fz10/R1 might work. Any help or info greatly appreciated to try and save me from ordering random springs to try.
