What are these carbs from and what will they fit?

#1 PostAuthor: dave cullen » Sat Aug 30, 2025 1:06 pm

Needing bit of help with these carbs, I'm intending to sell them but want to make sure I describe them properly!

I think they are VM26 26MM carbs with the airscrew on bottom but I cant see any markings or codes on them anywhere, I've been all over them.

As i understand it, the Z900A4 and Z1000A1/A2 use the same carbuerettor?

Advice appreciated, thanks

They were rebuilt by Wired George in the States in 2017 but have never been out the box, i never needed to use them as my Z1000 had a good set but i thought it might be worth having spare ones.
I dont have any documentation now so i cant confirm jetting etc but he did a great job on my Z900 ones that Rob Meggit set up for me.
I will be selling these shortly, and will adverise on the site first.

Z900A4 has the air mixture adjustment on the side (airbox end.) A1000A1 has the fuel/air mixture adjustment underneath (engine side).

To be certain find the carb ID which is stamped onto the top front of each flange (engine side).
I have a lookup table of carb IDs:
