Factory Turbo Bike Question

Hello All,

Does anyone have any idea what cam was used in the Turbo prototype ?

I'm try to work out the best cam to use in a supercharge Morini and it would help to know what the factory used.

Not a definitive answer but this was in Bike magazine, June 1982:
"...the few changes Morini have made to the 500's internals. It runs a stock crank but the low compression pistons are forged. Only other change specifically related to turbocharging is a beefed-up version of the two-plate dry clutch"
Which suggests it used whichever cam the stock 5-speed 500 engine had.
But they were only development prototypes so they may well have made cam changes for production.
