Carb fitment was created by Schu

I acquired this carb with the purchase of two MX250As and it is not correct for that bike. I have a bunch of Yamaha Enduros and I would like to know if this carb would fit any of them. Can anybody help me determine proper fit?

That at least looks like a DT360 carb. I do know those carbs had the boss mark near the choke.

edit: that 25mm looks to small to be a vm30ss. going check my drawings.

Schu, the number stamped on it will help id what it's from. Unfortunately, Imgur no longer offer their service here in the UK, so I can't see your photo! Could you post here what the number is? Ta.

I don’t see a number stamped anywhere on it. It has raised text that says ISO on the lower right side, and on the lower left side it says MIKUNI, and up near the top it says JAPAN. I will put the photos on YouTube shortly and post a link.

Thank you guys!
The previous owner of those two MX250s gave me that carb. He said he bought it thinking it would fit the parts bike that doesn’t have a carb and obviously it doesn’t. And of course I don’t have a DT250A……yet.
