KZ400 vs TX500A carbs

Since I had a set of both all apart on my bench, I did a side-by-side. They are really similar. Some, but not all parts will interchange.

KZ400 will always be on top or to the left.

First we have the plates. As you can see by the choke spacing, the carbs are closer on the TX.

The KZ plate also goes deeper into the rubber holders.

It looks like the bowls are 100% identical.

Throttles physically fit, but the holes are in different places. Probably wouldn't run right.

Caps look identical. Gaskets look identical.

TX springs are longer. Might just be more worn...

Bodies look the same.

The bushing that goes into the choke area is different.

 Tops look the same.

KZ400:


TX500A:
60 next to the screw hole.
110 away from the screw hole.

Here you can see the brass restricting bushing difference.

 Same.
