Dat modeling…
Have a 5 star rating! 
Just amazing.
Is this carburetor? Still needs help to understand what this part is
Firstly, well done with the modelling.
I found this forum post because I own one of these bikes and was searching for some info. I think it’s worthwhile creating an account just to let you know you’ve done a great job. I’m not a 3D artist, but I’ve used Blender before. Also, since I do my own maintenance, I’m quite familiar with most of the parts. Even I get a sense of satisfaction seeing them modelled in 3D.
Which leads me to my second point - that part is a throttle body/assembly.
If you ever need to figure out what a part is, or get some good diagrams for modelling reference, try searching for the workshop/service manuals. For example, you can find the ones for this bike on this forum post:

Thirdly, I don’t think the tank looks quite that wide. I could be wrong as things look different in person, but you should be able to see for yourself using photos from a different perspective, or from a top-view diagram.
Excellent work!
Sport1000, thank you so much for your kind opinion, its very important to me. And especially for the workshop. Thanks to you I know what this part is, and I can return to my work =) <img src="/uploads/default/original/4X/5/4/d/54d6cbe20b760987c65ade2abba070c96ea737d4.jpg" width="690" height="388"><br/> P.S. Yes, your right about the fuel tank. I`ll work on it.
ive gotta say, Im impressed. Im not a fan of classic bikes TBH. mostly modern sports bikes, but this one has my respect for sure.
That’s some of the best modeling I’ve ever seen. You are really talented. Is accurate mechanical design your job or are you just a hobbyist?
I like it, your modelling skills are outstanding !
Thank you, Thornton. I`ll try to do the best I can
Thank you, it was hobby at first, but last 2 years it looks more like a job )
Really nice modeling here, can we have a wire please 
?
Beautiful work Volden.
This is a modern bike
