The round slide (VM series Mikunis) ID is often difficult to find and to see as it is small and engraved into metal. It is on the flange of the outside carb as shown in this picture. The number can be four or five numbers and letters but most Suzuki Mikuni VM carbs seem to be five numbers in the 4nnnnn series. The number in the manual may be 41234 but it will be stamped on as:

4 1 2
3 4

and will be located here:

Just checked the number on the 1000S and it reads

P9
61

Nothing else in that spot.
