Need help to ID this HUGE mikuni

Brandon Weiss (Detective brandon to you) /

Offered to help somebody with their Yamaha Riva 125, and somebody before them had slapped this giant mikuni on it and didnt tune it, and I may need jets. Can anybody help ID it? It doesnt have a size or model on it, and it might even be a knockoff....unmarked jets. It's a 4 stroke carb, it has a butterfly valve and a diaphragm operated slide.

It looks like it might be a Generic version of the stock carb. Like the cheap ones you buy on ebay. The biggest difference I see is that it has a manual choke rather than the stock electric choke. i would measure the diameter and thread of the jets and see if mikuni jets are the same.

I didnt think to check, but now that you mention it I do recall the main jet being about the same size as 5mm dellorto.

This carb is much bigger than I think the stock carb was (dont have the stock carb), somebody had cut a hole in the plastic fender so the bowl would fit.
