I think the title about sums it up. How do you tell if a dual disk clutch is worn out. I see some heat cracks and it is slightly discolored but I am not sure if this is normal wear for this clutch or it is worn out. It is a sbc3600 12cb.

 

How many miles, hooks, burn outs? Power?

Small cracks in floater are from heat not necessarily mean its wore out.

 

Have you called peter forward him some pics let him be the judge afterall he built it.
