Yep. Looks like some really old mikuni carbs, probably 34-36 mm by the looks of it. I wonder how it runs like that? Should run damn good considering the type of carbs they put on dirtbike engines with about the same size cylinder.

From the apparent vintage of the engine probably older.
Maybe AMALs.
