    GS850 Carb replacement question

    I wasn't able to find anything in the search about it, so I apologize if this has been answered or is an insane question .

    The carbs that I got with my bike are shot, almost completely disassembled and no parts with them, so I am currently looking for a new(used) set of carbs.
    It is my understanding that the 850 has 32mm CV (BS32ss) carbs. Are these carbs the only ones I can use, or will the 34mm (BS34ss) carbs from a GS1000 work?
    I noticed a couple threads about using different sizes of VM carbs, but...
    Total newbie, first bike. Teach me please .

    34s might work, but you will lose a lot of the low-speed crispness in the throttle response.
    They might also have different spacing between carbs, I don't know.

    If your carbs are that bad off, there are a few sets available on eBay right now.
    (I know, I just spent the last hour browsing through about 1/3 o the 2800+ listings for 850s.)

    If they seem to be a little expensive, just compare that with what it might cost to add all the parts to your current set.
    Send me a picture of what you have, I might even be willing to buy them for spare parts.

      Found a bank of BS32's at a flea market for $5!

      Thanks for all your help Steve. I'm posting the pics of my carb sets here for everyone else.

      This is what came with the bike.


      This is what I just got. Looks like maybe off of a 750? The carbs are the same, but the gap between #2 and #3 is slightly narrower, less than 1/2".

        Contact chef1366 http://www.thegsresources.com/_forum/member.php?u=448, he has loads of carb parts and experience in rebuilding them.

          Dan,
          Thanks, I may look into that, though I am so close to Steve, he is helping me (I'm VERY grateful for this!) so I'm sure he will know of the available resources.

            Those are probably from a 650, I think if you swap carb number three, the choke rod, fuel T, and the two mounting rails, the central spacing will be correct for you 850. I have several partial racks of 850 carbs, maybe I have any parts you need as well. I need some 650 pieces too, we can swap.

              I have been conversing with him via PM. I have most of the parts that he needs, and I feel that between his original rack, the "new" rack and my spare parts, we'll have him going in the week that I will be home.
