Long shot but does anyone have a manifold lying about to fit bike carbs to a xflow motor, don't mind a bit of fabrication to make it fit. Alternatively a plate cut to suit inlet ports would do !!

i recently brought of ebay a basic steel plate cut for a zetec and in his advert said done other engines and materials, may be worth a search under 'zetec manifold'
alternatively will get contact when get home tonight.

I cut my xflow manifold flange out of 12mm thick aluminium using a wood working coping saw with plenty of cutting fluid . Used a manifold gasket as a template after making sure the gasket matched the ports . Turned the stubs up to suit the T/Bs and got them welded up . Total cost about £55 and a bit of time. Get the carbs first
