have checked them there in good condition.have been wrapped in polythene to stop the water getting in.but took it off to check anyway and all pins in clean good condition so sprayed some wd40 in and reconected and re covered.but thanks for advice.have noticed one of the pipes coming from amal valve that went to the old airbox is still in situ but obviously now just venting to air could that be anything to do with it as it would normally be recirculating back into air filtr box if fitted
