New Discovery: Someone tried to make the flywheel thinner
Usually lightening is done by drilling holes or cutting away portions of the flywheel while maintaining rotational balance. I've not heard anyone doing this by making it thinner. Thinner brings into question any heat dissipation issues along with changes to the clutch stackup dimensions and the ability to shift. I suppose this could be dealt with by changes in the clutch pushrod length, etc.
I can't see how a thinner clutch would "screw up" the bike in the short term but I think it presents some issues that might detract from its simplicity and long term operation.

It should also be easy to find a clutchplate from an M72 or similar bike.
Leszek at Oldtimer Garage coulc probably help.

Sorry I didn't explain "screwed up", I'm not exactly sure what happened, but I suppose the thinning of the flywheel would mess up the torque somehow if the weight was reduced and the surface area of the fly wheel's teeth were reduced. But then again I'm not an expert and didn't do so well on my physics final exam

The easiest solution would be to find an original flywheel with the correct clutch parts. Milling the flywheel thinner could also cause damage to the taper wher it mates to to the crankshaft. Hopefully this has not happened.

So here's my question:
What would happen if you made the flywheel thinner and tried to drive the motorcycle?
