    Welcome to the Asylum/Forum. There is a wealth of info here and many members will have parts or know of sources. Carbs can be rebuilt as well as many other things. We like pictures if you have em and any questions will be answered as well as possible. You have come to the right place. Many parts on these are interchangable but you will have to be specific when you ask as many have subtle differences. Seats would be an example of that.

      i just got my bike in february first thing i did was sign up here these guys love these bike and are a huge wealth of knowledge.first thing down load the owners and service manuals.cataonic bug has the link. i got mine on my smart phone and can acess it while im working on her. a bunch of these guys have good used parts alot cheaper than ebay. nobody here will try to burn ya either. as far as iv'e seen anyway. these guys are in to restoring and riding not taking all my cash on a part its kinds nice. even on the hard to find or impossible to find parts someone on here allways has a way to fix and keep riding. if your looking for another xs11 or trying to sell one this is the place to do it.

        Thanks for the info. I love this bike! If i could just get it in working order. Ill get some pics as soon as i find my woman's camera.

        I have pulled the carbs off for a good cleaning and found that somebody has broke one of the float towers off(The reason it always poured fuel out everywhere). Got that fixed and seems to work fine. Then after i started tuning i found that #1 mixture screw was stripped and jb welded on. It has 110 mains in it and 42.5 pilots. I havnt opened up the diaphragm side yet but it seems to me that it hasnt been jetted right for the exhaust. From what i have found those are the stock jets for it. Its stock other than a kerker 4 into 1 and im wanting to add pod filters. So in less i come up with some ingenious way of fixing to mixture screw ill prolly be looking for new carb bodies

          Hey there Jeffrey,

          You're able to tell what your pilots are, so sounds like you were able to get them all out, which is a big thing because they like to get corroded in their towers, and then the soft brass head slots like to break/crumble when trying to loosen them! I have an 81SH and ran a 4-1 pipe on it and never rejetted it from the stock 110's for 8 years, ran fine. But when I put on Indy Pods and did a big bore kit, I then rejetted for that, so yeah, with Pods you will probably want to rejet...that combo usually calls for 3 sizes as a starting point ~117.5.

          You said the Mixture Screw.....so I'm assuming the screw that's down IN the tunnel on the top front of the carb body, that perhaps the side of the tunnel got broken off, and so the PO JB welded it?? Yes, pictures would be very helpful. BTW, did yours have the rubber plugs on/over the Pilot jet towers when you pulled the float bowls off? There have been reports of bastardized transition carbs with the sharing tunnel between the pilot and main jet tower with a matching slot/hole in the main jet needle/emulsion tube, so that the pilot jet would be fed via the main jet, so the pilot jet tower needs to be blocked off. But if there isn't the sharing tunnel, then your pilots feed from the bowl like the mains, so no tower caps.

          HOW did you fix the broken float post...hopefully NOT with JB Weld, it's been reported NOT to hold up with constant fuel exposure. More mechanical methods are required to fix the post.

          Back to the mixture screw/pilot screw....does the screw still screw down to the carb body so that the tip can just slightly protrude thru the throat of the carb...see the little holes on the top engine side of the carb in front of the butterfly. IF the tower is partially broken, you can use a same thread size bolt threaded down till it stops with a little oil on it, and then apply JB weld around it to be able to build up the threaded tower section, let cure, and then unscrew the bolt, and the pilot screw should then be able to thread into it and still work properly!

          T.C.

          PS, you said cleaning, hopefully you've read the Carbs 101 thread, and learned NOT to soak the entire carb bodies in CHEM DIP type cleaner, will destroy the butterfly shaft seals=vacuum leaks!!

            The pilot jets came out easy. There was no tower plugs over them. The float tower was broken about half way up so i just drilled and tapped both ends. Grinded them flat and threaded it back together with a small stud. Its slightly shorter but ill fix that with a washer when i go back in there for a rejet for the filters. Yea rubber and old plastic never like chem cleaners.

            The number 1 mixture/pilot screw is stripped completely. The whole tower has been broken off at the base and jb welded back on. You can push it down and it pops back up to where it was but it wont come out. I been riding it the last couple of days so i haven't been real worried about getting it out. It idles real good and runs awesome but it pops ever 5 or so mins out the number 1 carb when it warms up. Jets will be here tomorrow so it will be coming apart soon. Goin to check out the valves and chain as well(slight clatter)

              Congratulations! These bikes do get a hold on you in a way that is hard to describe.
              Yep, my 80SG has the same serial number so I think you are right on track.
              Sounds like you are doing well and the guys with all the experience and know how have already answered your questions.
              Welcome.

                Were you lucky enough that the same carb that had the broken float post had the broken mixture screw? Sounds like you have the later body style carbs. Someone may have a carb body they would sell you to fix the set you have.
                Life is what happens while your planning everything else!

                When your work speaks for itself, don't interrupt.

                    Well i pulled the carbs back apart to adjust the little tab on the float that keeps it from opening the valve to much and getting jammed opened(#2 would puke fuel everywhere if u ran it hard enough to lower the fuel level in the bowl). Threw in the new 120s mains and 45 pilots new fuel filter. Took it for a spin with the new pods on and discovered that they block all the ports around the mouth of the carb( Crap didnt know that was goin to be a problem. Should have look at what pods were used by members on here.) So i cut the flared end of the boots that goin into the oem airbox off and used them as a adapter for now. Runs good but the exhaust is more prominent now of accel and especially on decel. Sounds like a little bumble bee on decel. Not backfireing or nothing like that. Got new plugs as well to do some more testing to see how close it is to being right. After that need to check valves and chain tension. Redo both petcocks. Carbs are currently feed off one port on one petcock. Change the oil and shes ready till something else breaks
