Flywheel alazzurra pantah as aleggerirlo?

I would like to lighten the flywheel of my alazzurra, I assume that is the same as the other Pantah, someone already tried to remove as it can, and to what extent?
In addition, the flying of the 750 F1 is lighter or the same?
Waiting for answers from experts.

not an expert , but the most difficult is to release the nut at the end of the crankshaft ,
then it all come easy (rotor generator ,ignition wheel with starter/clutch wheel )
