What carbs?????

I,v been reading some specs on my 78 kz400b1... it says that the carbs are keihin cv32x2, but i also read that there is a misprint and that they are keihin vb32x2. I want to look into getting carb kits for it but not sure which carb it is. Which one is on my bike and whats the difference between the two? I know that mine has the rubber diaphram in them.

I don't know about your particular bike but have you tried the KZ400 site? If nobody here knows then they would be your best source.
