identifying carbs

[vcman27]

I want to thank Viennahog for his help with my leak. But now i need to figure out what kind of carb it it is on this beast. It's a 01 fatboy that is stock and the reason i dont know is this is my first real bike . Any help in this matter would be great.

If it's stock, then it is a 40mm CV. Nice carbs.

Does anyone have a write up on how to clean the carb and replace the air filter on a 2000 softail?
