1983 gas leaking between carbs

[Guest]

I have a 1983 GS850 and i am new to the Carb scene. I have a leak from
between my carbs and just want to know if there is a seal located where
im pointing to in the picture, and how to change it out.

Hi and welcome.
Those connecting pieces generally have o ring seals and are known leakers after time especially after a carb rebuild. Parts fiche will show it up. Carbs have to come apart or be ' de-ganged ' to get at them.
In case you haven't yet found it.........

PS there should be a vent pipe on that link and it's opposite number. Put it back on before reassembling the carb set as it's almost impossible to do afterwards.

You must ungang the carbs and replace all the various O-rings to do the job right. Check my signature for a link to a useful rebuild tutorial.

Thanks guys, I figured there was one. is it as easy as unscrewing the plate that goes across and pulling it apart? your links didn't work

Sure
First off those screws on the rack look original. That means they will not give up without a fight and they are not Phillips head but JIS. They will get damaged pretty quick if the wrong tool is used.
You need to have a close look at how the choke and throttle are locked to their respective operating rods as they have to be opened up too.
This would be a good time to consider a thorough clean and replace o rings inside the carbs.

There are TWO 'plates' that hold the carbs together. And, if you are going to take them apart even a little bit, it only makes sense to take them ALL the way apart and refresh the innards, as well.

The leaky area in question is the fuel transfer tube (not a vent as suggested above), hence the leak. A full set of new o-rings can be purchased very inexpensively from cycleorings.com, which is run by one of our members. While at that site, also seriously consider getting the intake o-rings and the stainless screws that hold the intake tubes to the engine. Do NOT waste your money on "rebuild kits". They frequently contain inferior parts and not all the parts you need to do a refurb.

Apparently the links are down to the carb rebuild tutorial, will have to find an alternate source for it.

Just go here: Rebuild Tutorial and you'll have all your questions answered.

I'm sure you are smart enough to take close up photos of the rack and mechanisms before you separate the set

this is very unfortunate - and on a scale of 1 to 10 it is over an 8 - beware a mistake will not only hurt the carbs functionality but screws getting sucked into the engine is a very strong possibility after a set is separated. - You really should never reuse the spiked throttle plate screws - and maybe ask the experts where to obtain them.

Take those carbs and send them off to Steve (if your in the USA) and have them pro cleaned and forget about it. Once they are professionally cleaned they'll be good to go for another 30 years if you take care of your fuel system. Sometimes is worth the $$$ to just have it done correctly. Also put in your signature where you are located

thanks everyone for the help. I just traded my 03 636 ninja for this bobber style 83 gs830 and the carbs were just rebuilt but had that 2 leaks. 1 leak was from the a bowl that was not tightened all the way and the other is from the fuel transfer tube from the far left carb so hopefully I only have to take that 1 off along with the gang plate and idk if the choke will be able to stay yet.

Do you feel lucky? Best to assume carbs were improperly rebuilt before your arrival. Only way to know is to do it yourself - these carbs don't like quickee fixes.

Do yourself a favor and replace every one of those JIS screws with SS allen head fasteners. On the carbs, gang plates, every where. Make sure and use lock washers in the right spots as well. They have kits available to replace every thing on the engine.

Ok so I fixed the leaking o ring but after I got it all back together all my carbs are leaking from the intake side out of the bottom right hole as shown in my picture.

Picture for last post

tap on the bowls..may be a stuck float from turning the carbs around.
