So most people seem to go to 5Kg. Is this a limit where Idle becomes a right arse if you go any lighter?? I'm just thinking of going a little further. Or is there just no more 'safe' material to remove, hence why SBDs ones go special after 5kG??
Does lightening the crank have the same effect as lightening the flyhweel then? The weight in the crank seems to be situated quite far away from the centre line of the crank..
