Well I stopped a the local motorbike spares place here in Canberra and found an R1 carb setup for $150, its a bit scrappy, some screws are missing off the choke rail, and one of the black plastic covers has a crack that should be easily fixed with some araldite... Going to consider this option if the single 40 delorto plan falls through tonite on ebay...
Some of the prices for the manifolds for the bike carb setup on ebay are pretty decently priced, and I know some decent welders so Ill let you all know what happens.
Cheers,
Rob
