Let me know if you really need a clutch. I could build you one if you can provide me a core pressure plate. I could either do a dual diaphram or change the clamping pressure.

As for discs.....I have tried those kevlar disc and they are very sensitive. you burn them once and they are done for. They need a certain amount of pressure or they will fail. It is hard to beat the stock Sachs disc and change the lining to better material.

let me know if you need more help.
