Need help identifying some parts

I acquire some parts in a storage unit clean out and need some help identifying them. Any help would be appreciated.

I think the little one is a 1972(ish) Yamaha AT1.




Maybe a Yamaha DT250?




Here's the top of that carb

 

Both big fuel tanks look like XS650s to me, most likely early '70s (70 to 72)models.

 

I think you're right! It's looking like the carb is XS650 also. I think the small tank is a DT series, as well as the tail light assembly.

 

NOt sure for the carb, I use to see them by pairs for these twins!

I know that Solex made carbs for the XS650s but maybe for other models too. The one on the pic looks like the ones on my '77 XS650 but it seems a bit different in small details.

 

I have another of that carb. I looked at a pic of the xs650 set and, like you said, it has small differences. I think when you look at the fact that it was with these two xs650 tanks, it probably is xs650 also.
