Stiff Clutch Springs for 4 post Dry Clutch

[koko64]

Got a billet, 4 post clutch hub weighing 450gms in my M900. You can feel it combined with light plates and basket. Since there are only 4 springs, does anyone know a source for stiffer springs?

Ducabike and DP make 4 spring slipper clutches so that will guide my enquiries.

I've got 6 of some quite stiff springs, they're stainless.
And they're all but useless to me, I've tried 4 but with a Yoyodyne slave the pull is nice and light but feel is just not there.

Can you remember what brand they are mate? I'm using 4 TPO polished springs that are hanging on at present. I think they are some type of special material.
Im interested if you dont want them.

Had 'em kicking around in my spares, no idea at all where they came from.

I'll dig 'em out and measure 'em up, make sure they're not the same as you've already got
