I will also highly recommend lightening the flywheel and have the clutch/flywheel assembly balanced. You will like the difference it makes and it also helps in preventing crank breakages.
I asked JPC about lightening the flywheel and they suggested leaving it as it is, everything else I have heard and read suggests otherwise though. I'm not sure who else in Melbourne I can speak to about getting it all drilled and balanced.
