Can anyone please tell me what kind of carbs these are? I need to get a rebuild kit and I’m not sure what I’m looking for exactly. Thanks for your help👍🏼
My bike is a 1977 XS400D. 2A2.

I need some help identifying these carbs. I want to get a rebuild kit but I’m not 100% sure what the best kit would be. Any help would be greatly appreciated. 🙏

Mikuni BS34. They are the stock carbs on all XS400s. Probably pre-1980 as I don't see the drain screw and nipple on the bottom of the float bowls (could be the angle of the shot though, or it is hot out and I have had a few cold ones and can't see too well).
 
Those look like Mikuni BS34s to me too. The drain screws are located on the left-hand side, and I think the angle/recessed position makes the drain spout hard to see.
