the best carburator

Hi
From which bike(from 1985 and on) I can take the carb set for gs1000e 1980 bs34ss and its bolt on without any modification?

The GSXR carbs 36mm Flatside will work but they will have to be jetted.
You'll also have to buy K&N filters for these carbs.
I do believe the years for these carbs are 88-91

I HAVE ALWAYS WANTED TO KNOW,WHAT IS A FLATSIDE CARBURETOR, AND WHY ARE THEY BETTER?

The problem in the design stems from the basic slide design. Its length and the shape below the slide promote turbulence which hinders proper airflow and atomization. The key problem is that (when looking at the front of the slide) the back part of slide is much lower than the front and the transition is not airstreamed. The incoming air hits the back of the slide and then bounces down toward the needle jet and what is not deflected down is spun into the inlet.

This problem is minimized on flatslides by making them much shorter; that generates a stronger pulse below the slide because the air flow is increased. On the D-slide [as on PWK] this problem is even further rectified by making the slide even shorter and the mid section of the slide is airflowed to minimize turbulence.

Thanks! What then are 'semi-flat' and do they offer a significant performance advantage over the stock carbs ('82 1100E).......I am talking about the 36mm's off a Suzuki RF900 (1994). Or are they not worth the bother?

Any of the flatslides or semi-flatslids will be better than the round slides. The true flatslide are the best but when you get those from the GSXR or the RF900 bolted on and jetted it makes a huge difference. You just have to make sure that they get jetted in right.

Are these the same carbs we're talking about here? These are supposed to be 34MM smoothbores?? How good would these work, jetted of course, on a basically stock 83 GS1100E?

They look like either 33's or 34's and they will work a lot better than stock. There are a lot of choices and it depends on what you want to do.
