The book I spoke of is the Sudco dealers manual/catalog.
If you are looking for a book to use at home there is the Sudco/Mikuni Tuning Manual...an excellent source for carb theory and practical jetting/tuning information, parts, diagrams...it is "step 1", in the "12 step program".
The book can be found on ebay.
