carb id

how do you tell the difference between vm29's and 33's? thanks for the help.

Cant you just measure the inner diameter on the air cleaner side?
Im sure someone knows more but thats where I would think the easiest place to start is

The carb tops are very different. The 29mm carbs use the same top as found on all the KZ900 and all the 77-80 KZ1000 KZ650 carbs.

You'll see from the gaskets the how different they are.
