It's probably too late, but if you ever do end up immersed in a carburetor addiction please try out the DCOE equivalents from other manufacturers. The Dellorto DHLA is in my opinion
a very worthwhile option as it seems to have the all of the best features from the weber and Mikuni range.

I have found Mikuni's to be a great carb too.

I'm about to run some 35mm DHLB which are a tiny version of the DHLA (but with exactly the same (choked) bore size) They have a closer bore spacing which one could argue is better flowing (into the ports).
