My 1986 alto with a 1990 f6a rsr motor in it has started surging when it gets hot.Any ideas ? Checked a few pipes & fittings .Been working on ex gillies 1990 rsr works alto.Got the crank & My new forged pistons in.Getting crank & cam seals tomorrow.there was none in the gasket kit.Thought they would have been in there.New ex valves in head and ready to go on.Trying to get it ready for the sunbury run.Have pinned & joined broken rear mid wing.Got to match up matillic paint.got the tension figures from local shop.cheers.
