Just finished fitting my 70 kit (Polini cast iron), and have also fitted a [cheap] over-range variator http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... 0184155648 What weight rollers should I fit, I've got a mixture of 4 and 5g in at present, making 4.5g average.. does this seem a bit light?
A little experimentation is required Try fitting 5.0g and see if it goes better...if not youve got plenty of rollers in that kit to try out
