BS34 carbs, but from what bike?

Searching around the parts fishe and couldn't pinpoint what bike these carbs came from. Correct me if I'm wrong but that shield piece only came on the later year shaft drive bikes right? Those bikes came with a different type of choke actuation though. At any rate, open to suggestions...

The shield thing is just an improvement above the spring wire thing that holds the clutch cable is my thought. They would work on most any bike with the choke knob coming up the center of the steering stem like the 750L I mentioned. His bike is chain drive too by the way but has that style choke linkage.
 
The choke linkage is typical of '80/'81. It was changed to a J-tube that pulled from between carbs 3 and 4 in '82.

I have seen the shield several times, but never noted a pattern as to which bike they were on.

Looks like an 80 or 81 GS1000. There's a faint black writing that has the assembly number imprinted on the side of the carbs near the top. If it's still visible the post the number. Should be something like 49160.
 
The parts fishe says the first year for the shield was 1982. It wouldn't be the first time the fishe was wrong though.

'82 had the different choke linkage.

Of course, a previous owner might have changed something, too. I have '82-style choke linkage on my '80 850.

I've seen too many 1980 and 81 models that had that plate style guard to be coincidence. What's interesting is that the 1981 parts fiche for the 1000G doesn't show either the wire or the plate style cable guard while the 1000GL shows the wire style. Could just be another Suzuki parts fiche error.

I think it less likely that someone would have replaced the choke linkage from the newer style to the older style then replace the wire guard, that's known to break, with the metal plate that never fails. I know that I've converted several older choke styles to the newer lever style choke.

Bottom line would still be the configuration number on the side of the carb body.

My 82 1100G has all the same brackets and guard, but different choke linkage as Steve says.
I just overhauled my carbs and could find absolutely no reason to keep that steel guard plate. I suppose it was for the clutch cable, if located between 1 and 2 carbs. I have my clutch cable outside for less internal friction.
There is even a wire cable holder near the petcock for the clutch cable, so that plate must be an assembly line appendix.

I'm beginning to think that the 1000G's came with the metal plate while the GL's came with the metal wire. Could also be a parts use up thing while transitioning from one to the other.

Either way, if the carbs came from a G then it doesn't really matter since 80 and 81 were identical. Now if those came from an E then that's another matter. That why I would like to see if the assembly number is visible.
 
82 1000 Kats use BS34SS Mikunis. Carb ID #49300. Main jets #110, Needle Jet X-1, Jet needle 5D58, Pilot jet #45.
 
Good info everyone. Thanks. 1000G carbs they are then!

I've got the carbs to the point where I'm putting them back together now. Bead blasted the outsides and replated all the hardware.

The float heights are really low. In the range of 18mm. The float needles and seat are OEM so I'm confused about the float height. I put a good bend on the float tang and now I've got the float height up to 20mm or so. I'm going to try them and measure fuel level the way they are. There is no reasonable way to get them up to 22.4mm like the book says. I've seen this before on different carbs but never have understood why.

Ya, seen the same thing as well. Seems like some require a very large bend on the tab while others are almost flat. Seems like swapping the needles out makes the biggest difference. I'll pay a little more attention next time to see if I can nail it down as to why. Maybe chef can chime in as well.
