Post pics please, as there's 391 ways of describing pilots, jets etc...
Somebody with same carb will pick it up, specially if you don't have original carbs.:-D

Well I got my carb problems worked out, thats done. All I'm asking now is how other people got their carbs back on their bike. I'm sick of wrestling with the carbs do I have to move the airbox or something to get it on?
 
Wrestling with the boots and the carb IS the best way to put them back on. If they are new boots they are usually soft enough to make the job somewhat easy, but still not east. Patience is the best way. I like to put the boots back into the airbox first as my hand are really big. If you can loosen the airbox and move it back than yes that would certainly help. It sounds like you only have two carbs...great place to start. Try 4 8O

Thanks buster!
 
I don't know how much room your airbox will give you but on the Honda CB that I rebuilt, I could hold the airbox back far enough that you could put the front in first and bring the back up into place...the 1100 GS so far has been a big pain. Even the battery on mine is below the airbox so I will be searching out a maintenance free battery option if one exists.

I've heard alot of people talking about "Pods". I did some research using google on the subject last night and it seems to be little individual air filters that go on each port from the airbox to the carbs and replace the airbox all together making life easier. The only thing that makes me go "ugh" when I read about them is it said that most carbs will need rejetting. If I were to get these pods for my bike where would the air return hose from the top of the engine running into the airbox go to, or is that something I could just leave unconnected?
 
I'm kind of in the process of doing the same thing (rebuilding my carbs) on my '81 450L. Seeing that Mr. Barr is working on a 450 o-ring set is a very good thing!! I ordered one of the regular sets last fall, thinking that it would work well enough, and I'd have an extra set of O-rings if I messed something up, but now that I've actually got the time to start working on the bike, I realize that there are enough differences to halt my rebuild for now. I odn't even know if any of my existing O-rings will even fit. Kinda sucks, since I've got one carb dipped and cleaned, and I was going to assemble it as I disassembled the other one, just to reinforce my re-assembly memory.

On a mostly-related question regarding the fuel inlet T for these two carbs: the o-rings look to be built-in to the rubberized coating of the 'T'. Should this entire piece be replaced? The carb-clean/rebuild guide didn't really mention this at all, unless I missed it.

It should be ready in about ten days -- perhaps the 25th or so. Depends on shipping time from one vendor.

Now that I have a guinea pig to play with, I compared my existing CV kit with the sizes I need, and there's nothing that really works. I suppose the adjustment screw O-ring could stretch and seal, but it's really too small in ID. So the new kit will be all new sizes.

That rubbery 'T' can be re-used, provided it's still halfway supple. They're really expensive -- don't recall how much, but it's up there. I have no idea why they last so long, when the O-rings in the same set of carbs will be crumbly and crunchy.
 
Well, consider me on the list to buy a new kit!

the T's are about 25 bucks each (bikebandit prices), but I'm not 100% sure how to tell if my existing one is "supple". it's not squishy in any way, but it does seem to fit into the carbs in a snug manner. upon close inspection though, things are cracked, almost separating the "O-rings" from the rest of the rubber. I think I'll probably get one.

Bikebandit does have the O-ring for the main jet, at 83 cents, but they don't seem to have the gasket for the choke plunger assembly, or the O-ring for the pilot air screw. Fortunately, my gaskets (float bowl and choke) are both still flexible and undamaged.

Is your kit going to be O-rings only again, or will it include any of the orange-ish gaskets (needle valve seat, choke plunger) ?

I'm looking forward to actually getting this bike up, running, and on the road! Hopefully, getting around 60mpg too (47-70 was what I read somewhere that the manual specified).

Heres some pics of the bike, waiting for new airbox boots to come in, then I'm gonna clean it up and post some good pics, enjoy. The windshield came off about ten seconds after these pics were taken.

Hopefully you plan on putting the windshield back on sometime, too. That is a nice little shield.
You would be amazed at how much protection it gives you while tooling down the road.
As the insect population increases over the summer, wind(bug)shields become even more popular.

Just O-rings. The gaskets tend to last forever, and when they don't they're usually available somewhere else.
 
so, the idle fuel mixture screw oring IS my problem. it looked so close... as soon as its ready, ill be ordering a set too.
 
ALRIGHT!

Words cannot explain how happy I am right now. I was getting to the point where I was ready to say screw it and sell the bike but I held on and made it through. I rebuilt the carbs completely, replaced the boots on the airbox, replaced the fuel lines and cleaned the tank.

The boots came in Saturday morning and it was go time. I unscrewed my airbox and moved it as far back as I could and I swear to god it took me the next two and a half hours to get those boots back on. I got so frustrated I was ready to dump the bike over in the driveway and go do something else. I finally got the boots on, switched the petcock to prime, waited a bit, turned her over a few times, and she fired right up!

Brought the choke out after about 30 seconds and she purred like a kitten. No more idle problems without the choke, and no more throttle delay! It was very frustrating at first to do the work myself but it all paid off as soon as I was going down the street on my newly fixed bike.
 
Next up in my list of "to do"

The front wheel makes a little squeal while riding. Should I WD40 the axle but make sure to keep it away from the disc or does anyone know what could be causing this?
 
It may be time to dive into the next project...replace the bearings.:D

Yep! This project should be a breeze compared to getting carbs back on. LOL!

Your not kidding, I seriously feel bad for people with a four block carb, my two block drove me insane, forget a four block.

Been there, done that (see signature pic). Not fun. Seriously considering pods at some point in time.
 
Is the bearing problem something that needs to be taken care of like asap? It's got a little bit of break squeal it seems, so I'm not sure if its the brakes or the bearing making the noise but eaither way I'm worried about the bike being unstable at high speeds, or the front wheel locking up on me out of no where.

I had it up to 45 last evening on a back road and it was very stable.
