lightening a flywheel

[Seabee]

Has anyone ever lightened a flywheel on a 300EX? If so, how do you do it?

I have had flywheels lightened before when I used to ride a 250R. It has to be but in a lathe and machined down.

I can mount it on a brake lathe weight  it before and after, I know that the YFZ if to light with create deflection. anything more the -6 degrees

You usually turn a fly wheel when ever you do a clutch job on some cars and large trucks. Take it to a machine shop that is reputable and they should be able to turn (cut) it with precision.
