Great video on the work bench sequences. I learned quite a bit. Also, glad to see you are being careful with chemicals. When I worked for Sunnen Products in the 1970s we used 1,1,1-trichloroethylene in the ultrasound machine and for degreasing. Maybe you have something safer now. I hope so. Very dangerous. I think '111-trich" is still out there in the motorcycling world as an additive for dirt bike air filter oil to help it flow. You can avoid contact by putting the foam filter in a plastic freezer bag and work the oil into it, then squeeze the excess back into the bottle. And I would go so far as to say don't try to clean dirty foam filters with solvents, especially "111-trich".

Thanks for the information. I have a 1982 SUZUKI GS 550 L that I rescued, and my next job is to pull and rebuild the carbs. Now, it fires on #3 and #4 but not on #1 or #2. After I run it for a minute or more, gas ends up in the exhaust pipes. Carb issue? By the way, I cleaned the tank of rust by first cleaning it with Spray 9 and then Metal Rescue. It worked well.

I guess it keeps things interesting, but when I was researching carbs, I was so annoyed by the many different layouts. As well as things having different names. It was nice hearing you mention the little things that I did (as well) on my own that was right. When actually watching this, I was amazed with everything that I got right, and I actually wondered how I knew some of the stuff (like the assembly sequence for the mixture screw). I guess that's what happens with a lot of research and a workshop manual .

Just came across this video. Now looking forward to getting the carbs off (81 GS550) & checking them. I paid someone to repair/rebuild them last year & it ran great after. Then after I let it sit about 5 wks the carbs started leaking whenever you start it...and I assume that it is the floats sticking? Gas pretty much just flows out of 2 of them after a few seconds of running. This video will certainly be a help. Thanks for posting it.

[@BrickHouseBuilds]

Im happy to hear its helpful! Yes, stuck float. Simply tap on the carb bodies with the handle end of a screwdriver and it will hopefully stop. If not it has some debris in the bowls

[@kanuckelwolfe4490]

I know you are busy, but maybe you will see this: I replaced the needle & seat(of what I thought was the offending carb...#2) & all bowl gaskets, put the carbs back in then it leaked worse :( Maybe it's leaking somewhere else? Once it starts, the fuel drips under #2 and #3 and seems to be coming from the middle of the carbs. Where is the fuel supposed to leak out if it is a stuck float? (I plan to replace the remaining needle/valves before I wrestle it back in) Thank you.

[@kanuckelwolfe4490]

Discovered that the fuel inlet tubes between 1&2 and 3&4 were the leaking culprits. Now just waiting on some o-rings and JIS set to give it a try.

I am working on 1983 GS450L and it has the Minuku carbs on it, i,m sure different jets and things from the 550. But my question is about the fuel control needle. I have torn a few carbs apart and have never seen one that has no connection of the needle to the float assembly, so it just opens from the fuel flow? The float does not pull it down? Great video by the way, I prefer detail over some of these guys skipping over what they may think is unimportant. They don't realize the big majority of watchers are inexperienced knuckle busters such as myself. Have a 550 to do next so really glad I found this.

[@BrickHouseBuilds]

Correct some do not have a tab to "pull" the needle down as that is forced down from fuel pressure and gravity. Im glad you found the videos helpful though as I do try to pack in the details

I noticed when you reassembled your bowl, you didn’t put the seal back that’s on top of the aluminum cylinder that acts like a check valve. (It is right under the portion of the gasket that protrudes from the rectangular shape). You can see it as the bright aluminum circle right before you lay the gasket over it at 31:28. When I took mine apart I had a small circular rubber seal with squared edges that sat right on top of that. Did you not have one/ did you remove that cylinder to clean? Also - thanks so much for making this line of videos. It has helped me a ton with my bike.

Not sure what you mean. The black rubber passage plugs are shown being installed before the bowl gaskets. There are no other parts of the bowl gaskets

Thats not fun!

[@RyanBielman]

I am rebuilding the carbs on my GS550L now. The rebuild kit I bought - the pilot jets don’t have the perforation holes on the sides. Just the through hole lengthwise. From my understanding these holes are used for adjusting the air fuel mixture by feeding air through those side holes into the pilot jets at lower RPMs - but only when you have an air screw for adjustment on the air box side of your carbs. I don’t see that on the OEM carbs. What’s your opinion if this pilot jet would be okay to use?

[@BrickHouseBuilds]

You need to use exactly what your carb came with. There is very much a difference

[@bKoelle689]

Very helpful, this is the next project to tackle. Got the body work all done on the gas tank. Any advice for rejetting the carb to run pod filters and a 4 into 1 exhaust?

[@BrickHouseBuilds]

Hey Ben glad this was helpful. For intake/exhaust jetting here are my tips: Buy quality pods - not Amazon. Look for UNI, k&n, DNA. The same advice goes for jets. Expect to buy multiple sets of mains and multiple sets of pilots as you will have to make changes as you go. EXPECT to not get it right the first time, 2nd time, or 3rd time. Make sure carbs are synced and there are no simple issues.. Start with tuning the idle circuit using mixture screws and pilot changes if necessary. Then start working on part throttle which can be tricky if you don't have adjustable needles. Then focus on WOT main jet tuning paying close attention to the plus and timing marks. ONE CHANGE AT A TIME! Adjusting mixture settings is one change. A different pilot jet is one change, etc. Write changes down and test.

[@bKoelle689]

@@BrickHouseBuilds Awesome, thanks for the advice! Was going to buy those K&N filters from the start. Was going to go the ebay route with the jets, would make since to buy the higher quality jets from the start as well.

There was a set of jets pilot jets you put in under the rubber plug ..you said make sure you've got the 6 hole instead of the 8..what does the engine do if you've got the wrong jet in it ..what it's symptom..?? I've got a 1980 Suzuki GS 850 L ..had the carbs apart cleaned..adjusted jets and needle height several times .. Starts and runs at idle ..after 1/4 throttle just looses power ..bogs out ..won't build rpms ..with pod filers..no filter ..air box on ..the only way it'll build rpms is if I close off air inlet to air box .. After seeing this video ..wondering if this jet may be my problem..oh..it has 4 into 1 pipe ..has muffler in it ..

[@BrickHouseBuilds]

The holes dictate how much fuel passes through that jet so they need to be correct. I believe I saw your question on a Suzuki GS page yesterday actually. To me, without being there it sounds like your slides are not moving as they should. Possibly a poor seal on the diaphragm sealing surface, torn diaphragm, blocked vents, needles dragging on the emulsion tubes, etc. If the slides don't rise you will not get adequate fuel. When you block off the inlet you are creating more of a vacuum across the carburetors which is raising your slides. Not a jetting thing. This is also only if all things are set correctly. Set your floats to exactly factory spec and all exactly the same...exactly the same. All mixture screws the same, no air leaks, then vacuum synced. ONE CAHNGE AT A TIME. Write down your results like a science journal.

[@theandyvioletteproject3385]

Hey sorry could you clarify where you measured float height - seems there is competing info online, did you mean from the well where the gasket sits, to the max top height of the float (part where the metal is fused to the plastic)? or did you mean the rise (or "lip') of the gasket well to the max top height? And could you please indicate mm value, just so I know, thanks!!!

[@BrickHouseBuilds]

You always measure from the body surface where the gasket would lie to the top of the float. I don't have the service manual near me which has all of this information in it. I always recommend buying a service manual with any motorcycle.

[@erniewebster792]

Where does the vacuum for the 4 internal constant velocity spring loaded diaphragm's get supplied from? I didn't see any vacuum lines going to the carburetors. Are there internal lines within the carburetors?

[@BrickHouseBuilds]

The vacuum comes from the intake pulse. The piston moves down as the intake valve opens and draws air through the carburetor. That is the vacuum pulse which raises the slides

[@gerardojimenez5465]

Hello, I have a question, why did you put 4 plugs? It affects something not having them when trying them

[@BrickHouseBuilds]

The rubber passage plugs need to be in these carburetors to control fuel flow. Not all carburetors have them. Your service manual or parts diagram on partzilla will show if your bike requires them.

[@djlancer88]

So I have almost identical carbs on my bike 85 xj700 (Mikuni) b33 I think) and I noticed when fixing a float leak issue that the pilot jets dont have the rubber plugs on them. The bike has pretty much always ran fine with out them. Should I get some plugs? The previous owner rebuilt/restored the bike so I feel like he might of known what he was doing or just forgot lol.

[@BrickHouseBuilds]

You should look at some parts diagrams to see if they are needed. Some carbs don't use them. Usually if you have a passage from your pilot to second you would need them.

Doing this on my gs650gl that I actually also got for free haha. How do you know when the mixture screws are properly “seated”?

I know I’ll have to adjust them when I go to sync them all I just didn’t want to break the needle if I screw them in too far.

[@BrickHouseBuilds]

You can just tell. As you thread them in theybare smooth and consistent in the force required to turn them and then you feel a resistance. Stop immediately and start backing the needle out while counting the turns. These will always be set the same amount for all 4 carbs. Sync screws are different

[@nlfishing1302]

Do you remember the float height spec

[@BrickHouseBuilds]

From memory no. Quick Google search will do it though

[@413Garage]

Did you have any hanging idle issues ? I have an 82 GS550L and It won’t return to idle if I rev over 2k rpm. It doesn’t seem to change when I adjust the mixture screws on the carbs. It’s been very frustrating. Lol

[@BrickHouseBuilds]

That sounds like a lean issue. Possible air leak around the intake manifolds or the mixture is far out. The carbs must be in sync and all mixture settings must be the same for each carb

[@413Garage]

@@BrickHouseBuilds looks like I need to invest in some tools. Color tune and some vacuum gauges. Thanks for the info!

[@BrickHouseBuilds]

@@413Garage I've never used a color tune. Set the mix at the factory setup and make small adjustments from there

I've got an 81 gs 850 ..carbs keep leaking .. Must have pulled them apart and reassembled 15-18 times in the last 14 days ..keeps acting like floats aren't doing there thing by shutting off furl...pouring out gas through air intake and air jets ...ive set and reset floats as many times as I've had it apart ... Any suggestions ...anyone .. Originally just cleaned up clogged jets and ports ..ive got a carb kit in it with new jets ..

[@BrickHouseBuilds]

A- are they brass floats and are they leaking fuel inside of them B-Are the needles in good shape? C- Are your fuel lines connected to the correct spot? There are fuel inlet ports as well as larger vacuum ports when can be confused.

[@jerryking1434]

@@BrickHouseBuilds needles are in good shape .. Also installed new needle kit .. Float are the black backolite style floats .. Going to check on my fuel hook up ..pretty sure I'm on fuel hookup ..not vacuum... 😉👏👍 Thanks .. 2 vacuum lines and one fuel line ..

[@jerrybigrig9475]

Update .. Got floats working properly .. Doesn't leak at idle anymore .. Now it runs ..won't go past 1/4 throttle ..with air box..without ..no vacuum leaks ..it's got a 4 into one exhaust ..it's got #115 and #40 jets ..idle screws were at 2 turns out ..went to 4 turns out ..no better no worse .. Any advice ..?? Changed out air jets from 190 to 180..made a slight impovement.improvement.. I'm wondering if I should solder them closed..drill the jets out to 170..?? Or drill out main jets from 120 to 125..??

[@ripntearslayer9101]

Hey, I'm working on an 82 gs850. Same carbs. I see a tear in one of my slides diaphragms, is that an easy replacement or do I have to find a new slides?

[@BrickHouseBuilds]

I think you can fin a new diaphragm but I do not know where to point you. Id do some forum searches but again I believe you can replace just that.

[@ripntearslayer9101]

Well I figured it out. I found replacements at jbm industries. Requires me to cut off the old diaphragms and retention plastic, but hey I'm willing to see if it works.

[@jerrybigrig9475]

@@ripntearslayer9101 did it work..??

[@evilestrook8180]

Would have been helpful if you would have actually shown measuring the float height and where

[@BrickHouseBuilds]

You measure from the carb surface that the bowl gasket sits on to the top of the float itself at the highest point.

[@gerardojimenez5465]

For Yamaha xj550 do they also have to be mounted?

[@BrickHouseBuilds]

See my previous comment

[@gavingerdes7749]

Hey I was wondering where to get parts at for a full rebuild?

[@BrickHouseBuilds]

Hey Gavin, check randakkas, z1 enterprises, or even partzilla for parts. K&l makes a lot of kits as well. Just take your time and know exactly what kit you need as there are many.

[@vincenzodimatteo2003]

I have the same carbs as you and I have a problem, the first two lose petrol but the tank gasket is fine, the needle and the float also do their duty, but nevertheless it loses fuel, what can I do? I thank you!

[@BrickHouseBuilds]

Like it drips out visually?

[@vincenzodimatteo2003]

Yes, you can see that the drops come out between the first and the second carbs in fact the first two carbs are dripping

[@BrickHouseBuilds]

@@vincenzodimatteo2003 so you have bad carb orings or bowl gaskets

[@vincenzodimatteo2003]

The bowl gaskets are good

[@BrickHouseBuilds]

So the o-rings between the carb bodies are likely bad. Common on old Suzuki carbs.

[@NeoGenesisCustoms1986]

Whats the spec for the floats? I didnt notice that mentioned

[@BrickHouseBuilds]

Factory height

[@angel2mayhem]

Hello ..wondering the float height ? what is the optimal setting..? :)

[@BrickHouseBuilds]

Per the service manual for the BS32 carbs like these the level is 21.4-23.4mm Be sure they are the same for all 4 and don't vary.

[@guillermomgarza3837]

How did you fix the tower?

OOps, I think you skipped that video in the series. Here is the dedicated video I made on that repair: kzbin.info/www/bejne/d52Qd6iLmax7rpI

Any idea what you set the float height to?

[@BrickHouseBuilds]

Just whatever the factory spec would have been. I don't know from memory

You undo the jam nuts on the cables and slide them out

​@BrickHouseBuilds carbs are back together, and it's running lean with my new pod filters on. Does tightening or loosening the fuel screw make it more rich? I'm getting conflicting info everywhere.

[@BrickHouseBuilds]

@justinbond9327 watch this video from Cody motorcycle MD. There will be no confusion afterwards. Also note that cheap pod filters on cv carbs do not mix. You may want to make sure the bike runs well without them first before making the switch kzbin.info/www/bejne/p2qkY4eCbreprbMsi=nG5c1DAFb_4ddGAo
