Mikuni Dual Carb Identification problem

Hello…I’ve got a 1981 Xs400 that the previous owner had converted into a cafe racer. They changed out the stock carbs and installed a Mikuni dual carb. I’d like to rebuild the carbs with the appropriate kits but I cannot figure out which type of carb it is. The “Mikuni” and “made in Japan” are in the cast and I know it’s a legit Mikuni I just can’t find the type or model number.
There are markings on it but they do not match anything I’ve searched for. I will attach the pics of the markings that are on the carbs. Could someone help me figure out what model carbs these are so I can purchase the right rebuild kit? Thank you for reading!!View attachment 37900

Mikesxs.net sells a mikuni kit with the vm32s, maybe that's what they put on?

Welcome. I don't know what carbs they are just from the numbers - can you post a pic of the entire carb?

If they are not stock, I agree that they are probably Mikuni VM slide valves as retrofit kits are available for the XS400 from a number of sellers. A picture of the carb will tell us the type and a measurement of the bore will tell us the size. From there you should be able to order rebuild parts.
