I found this doing some EFI research....
This is a product distributed by Fox Injection. Does it look familiar?
It is called the Heritage Throttle Body and is designed for classic sports car builders/restorers who want the fuel management improvement that EFI affords with the look of the traditional Weber DCOE style carburetors. This carb was used by lots of custom bike builders in the 70's and 80's. It comes in four of the sizes most commonly used by classic car owners; 40, 45 and 48mm.
Hmmmmm......
..... I wonder how a big bore M8 would like drinking from straw like that....
Anyway.... you can read more about it at the link below...
