Which Other Carbs Fit 1982 GS850GL?

[Philmsphee]

Building a 1982 GS850 and need to replace the 4 carbs. I'm finding on Ebay and other units from other years and models. Having a hard time deciphering what will work.

Looking on Ebay I see several sets but confused as to if they will work or not. Example, one for a GS1100, will any of these work? If not how do I best search and find a replacement?

Thank you in advance!!

Why do you need to replace the carb rack?

Why do you need to replace the carb rack?

Not knowing I pulled the idle tube that pulls from the bowl. I did it on all 4, thus rendinging it useless. I was pulling out the jets and other to clean and pulled / broke those thinking I would replace them but now I understand I need a new / used set.

Neither of those will run properly
There's a guy on the FB GS salvage yard selling a set

I did get on there and see there are some sold. However they are 28mm, and I've read it might be 32mm and other places say 34mm. So the more I look the more confused I get.

Did you look in the factory service manual or some specifications from Suzuki?

Those tubes you pulled are not "idle tubes", they are the pickups for the "enrichment" system, otherwise mis-labeled as the "choke". You may have a difficult time starting the bike when cold, but once started, it would run OK.

You have 32mm carbs. They were used on 550s through 850s from '80 and up. The 1000s and 1100s used 34mm carbs, they will not fit in the boots in the airbox or the engine.

Did you merely pull the tubes from the bodies or did you break them off? Either way, they might be repairable.

I do have a set of carbs for an 850, but they came from an '80. The jetting is pretty much the same, but the "choke" mechanism is different, and would have to be changed to match your '82 cable.
