Came from the fluid drive on a 1964 MK2 bike. One spring was stretched so I could never get it to work. Has been reassembled, per the pictures.
This clutch is required for the kick-start lever to work.
Note: Just to be clear, this clutch requires complete disassembly and reassembly using correct buyer supplied spring. One of the two springs works fine.
I will promptly remove this listing after it is sold so if you are reading this then the clutch is still for sale.
