Scooterotica

I was thinking of getting my flywheel lightened and balanced at the same time but was wondering what would be the recommended final weight , I thought about 1.8 - 2.0 KG. Its an SIL flywheel so would it need to have the fins machined down to achieve this.
Any input would be appreciated.

Cezeta and i had ours done by chalkie not sure what the weight was but give him a call
