Keihin carb identification

[attachment:2]C:\fakepath\image.jpg[/attachment]
Hi all

I'm a newbie from New Zealand any help you can provide would be appreciated.

I've got a KZ750 b4 and going off the manual and the Internet it seems like its got non standard carbs. I'm trying to find out what they come off so I can track down spares or a rebuild kit.

The Carbs are Keihin VB stamped with 31B D TJ and possibly a 9 or a Japanese character on the end.

Any help identifying these appreciated.

Regards Darren

no answer to this post yet??? I'm in the same ship except i have 3 sets of carbs that i know nothing about except one set are smoothies. tried search feature here but nothing concrete

Looks like carbs off a Honda.
Carb has 'old' style metal slides, KZs had rubber diaphrams in the early '80s.
For future reference have a pick of the inlet/air filter side,right side up.
And measure the inside diameter of the side that fastens to the engine.
This will tell what size they are,by millimeter, which 1mm = .03937 of an in..
