- The GS550 carbs get a full teardown and cleaning in this video after getting removed from the bike. These carbs fought me hard with varnished fuel, stripped pilot jets, stuck needle seats,and even a broken float pedestal! I first show you how to disassemble these carbs before showing you how to approach some difficult issues before showing you how to clean them. This video is packed full of information so stick through it for many tips and tricks on the process. Be sure to look for the next part where I make more repairs.

I enjoyed the video, because I like learning stuff about carbs.
Happy the video had stuff to teach!
Good to see the whole process. Very informative and many thanks.
Glad you found it helpful!
Listen, you had me at "get the bowls off", but it was the head-waggle @2:17 beckoning me to coming along with you that hooked me in this episode. Once again... excellent job and info.
Hahaha I just had to go back and see what that head waggle was lol. I appreciate you checking it out and hope the info was helpful !
Even with your most EXCELLENT instructional video accompanying this disassembly and even though this isnt the bike I will be working on, its still intimidating to me man. But maybe it was to you the first time you tore into one too, I dont know. But I really really appreciate you doing this and showing me/us the way to go about it, the tools, the techniques and everything. I will have a shop manual and I will buy the appropriate tools and do my best. Thanks loads.
Oh of course it's intimidating! Even when I did this video I knew much less than I do now. Just know there is a large community to help along with endless resources for information
@@BrickHouseBuilds One of many things you have definitely convinced me of is to buy a GoPro and a tripod and film myself with ALL disassembly so I can replay that sucker and remember each 'Oh yeah, that went there' steps. Thanks and continued success. Reallly happy I found your channel and I'll be buying some merch to display in my shop for inspiration.
@@pipersall6761 really though take a ton of pics. I do that too
@@BrickHouseBuilds Will do! Thanks!
So I'm finally getting started working on an old barn find up here in Nebraska after watching your channel for the last couple weeks now. Different bike type, parallel twins, but it's gotten me inspired. Keep up the good work sir.
Hey Im just happy to help inspire people to take on projects! Excited for ya!
@@BrickHouseBuilds thanks. I have a channel that I build things, it's been cosplay mech suit stuff, but I'm going to run a series on this build. I have a couple bikes in the works currently. Ones a frame up custom, and then this current barn find freebie.
I love that my 79' non cv carbs have fuel and air mixture screws. PO forgot to replace a vacuum cap so it wouldn't idle.
Which ones do they have fuel or air? Typically is the adjustment point in by the air filter they are air mixture and if by the cylinder head they are fuel mixture. The cv carbs have fuel mixture screws
Hello, thank you very much for clearing my doubts, thank you, I learned something new, I hope to continue learning from your videos, thank you very much.
Sweet! Very helpful. Looking forward to seeing how you fixed that float tower!
It wasn't too bad I just hope it lasts. I'm glad its my bike and not a customers so if it breaks its not a big deal
Just got a GS550, starting the build pretty soon. I know this part is going to be challenging. Very informative, subscribed!
I appreciate you tuning in and the sub! These fought me but it all went well. Editing the assembly video now to hopefully go up tomorrow!
@@BrickHouseBuilds Awesome! definitely will be getting those screwdrivers and one of those ultrasonic cleaners. mine looks pretty rough in some spots.
@@bKoelle689 Those tools are a great investment. Your mind will be blown once you use some quality JIS drivers.
Very informative. Thanks for sharing, BJ. Heading to the next video with interest.
Just found your channel, good stuff, gs550l was my first bike, loved that it reved to the moon and the 6 spd! Sold it to finance my wedding 9 years ago. These days I have a couple cb750s and gl1100 that is waiting to be my next project. From what I have viewed so far great videos!
Hey I appreciate you checking them out! There is a constant flow of different bikes through my shop and I try to capture all I can but its tough. I hope I can just offer some good tech and fab tips along with some mild entertainment
I have done 3 sets of Honda 750 carbs and found after disassembly for the really small plugged orifices an "E" string guitar wire works perfect. Also if you don't have an ultrasonic cleaner, soak the carbs 24 hrs in Pine Sol. Most time you will find someone else has buggered up the Philips head bowl screws so I just replace them and all other philips head screws with Allen head screws available at Lowes hardware.
I have a large variety of wire and string for such jobs. Also have an ultrasonic. I use baking soda in my sand blaster to do heavy external cleaning combined with multiple U.S. sessions
@@BrickHouseBuilds Yeah I watch your videos, very helpful and informative. Japanese carbs can be frustrating for someones first attempt at restoring them.
For those of us who do bodge and tinker in the shed. Not everything is exciting but has to be done. I am intrigued to see how you fixed that post. I could feel it breaking as you hammered 😨
I hated hitting that hard but it took some force. I just got carried away
Fascinating. Complex and intricate work. Good video!
Thank you! Glad you enjoyed!
Awesome video. Tip: I hook up my Dust Collector to my Blaster when I’m using it. Makes the work easier to see in the cabinet and stops my shop looking like it snowed inside😂
Thank ya Dave! I haven't really perfected my dust control for the soda blaster but its definitely something that needs attention
Nice one B.J. I really enjoyed the explanations on that one. They came up real nice after the soda. And a great shout on the J.i.s bits, must get me some of them & an impact. 😉🏴🤘🙏
Thank you! The soda doesn't leave them vapor hone nice but damn nice none the less. Absolutely grab the JIS bits as they will change your life lol
@@BrickHouseBuilds Yeah they is nice alright... Oh they are on the 'to get' list. Ha. After getting some screwdrivers a few months ago, I can imagine the bit & socket method would be awesome!! 😉🤘🙏
Bro I really enjoyed this playlist, new sub here I have the exact same bike , I mean exactly inspired me to get busy thanks!!!
Glad you enjoyed! They are fun bikes!
I have a 550 to and exact carbs thanks for the time given and the post - very informative
Im glad the videos are helpful!
Very informative in depth tear down on these carbs. Best of luck with fixing the broken tower 😣
Yea it was bound to happen at some point but still sucks. I think I have it fixed pretty well.
23:55 I had to do that on the carb of my old LS650/Savage carb.
Massive thanks, I just got my zephyr running from watching your vids!
Thats awesome to hear!!
Still getting psyched for that lockset bolt (~reverse drill bit, vise grips and maybe a 2/4 with light pressure from below may get it to move. yada yada) But now thinking that the carburetors have not been out in a long long long time I am "Assuming" that I need to get them out and clean them. (not gonna spend $1000.00 at the dealer for this.). I know you have a vid about the 750 carburetors I'll check for that too. Aaand I did find the Motorcyclemd guy who has lots of stuff about carburetors too. If I watch any video I try to say thank you. So here I am again. Thank you! Thank you, Thank you, Thank you. 〰✨👍✨〰
I enjoyed it learned quite a bit
Something I want to point out now that I've torn into mine on my 81, HOLY CRAP these have been some of the toughest ones I've done, giving me nothing but problems. 2 of those mixture screws up top have committed self death and stripped out the flat head and one was buried, was really hoping no one had been in there before but with a 56,000 miles bike, was bound to happen, and they are stainless and not brass, spent 8 hours last night doing surgery on them trying to remove them, ended up having to drill them out and now need to clean up the threads a tad so for future reference, and I will update this comment once I find out for sure, but the thread is m6x0.5 if I am right, again, ill update that if I need to, but in my head, its a good idea to gently clean those threads and lubricate well so they are easy next time, at the very least maybe take the old one without the spring and with some anti-seize run the screw in and out over and over till the threads are nice and even. Just my two cents but please ,for the love of basement jesus, take it easy lol
Took me about a week. Broke off a hardened steel drill bit in one of the screws in the process of drilling for an easy out. Carbide dremel tool 1/8 shank bit saved my booty.
To confirm, the thread pattern is m6x0.5, I got this one, worked great, and after cleaning up all the threads, even the ones that came out easy, still cleaned up alot of junk, totally worth cleaning them up if you feel like ordering off Amazon. Probably fits multiple carbs and would be a handy addition to a tool cabinet just to flex on your buddies if anyone else ever has an issue.

Hi, to raise the temperature of the aluminium boiling water is none harmful and very effective. Richie.
The only way to fix float towers, is to put the hammer back in the bottom drawer, and get the really thin, sharp side cutter out. grab the head of the float pin, and squeexe it between the post and the head. Two drops of phosphoric acid will free up the corrosion. Flush well afterwards!
The most incredible thing here, is that You kept pounding away on those poor towers - even after You've already broken one. These kinds of mistakes, were something we did in the eighties - before TH-cam landed. nowadays, there's no excuse for doing what you did.
@qivarebil2149 How dare I learn a lesson. I don't do it this was any longer as yes, it wasn't the right way to do it. What is interesting is that by having a video out in the world, people expect nothing but perfection and often don't allow room for mistakes.
Thanks…a lot of good information on this video!
Thank you
For removing the jets you may look into hollow ground flathead screw drivers they’re less likely to strip them out, in the gun world they’re imperative for the same reason. You can buy kits that have different widths and slot thicknesses.
Very true however I grind my screwdrivers to fit jets. I use the same ones for the same jobs
Massively helpful video, thanks for posting. One question though - how did you replace the mixture screw caps as they were drilled off and I don't seem to be able to find replacements anywhere.
Thank you! The caps are not needed as that was just an EPA mandate and not necessary.
@@BrickHouseBuilds thanks for the quick reply! That’s great, I’ll stop trying to look for replacements now
HELP! HELP NEEDED! I started to disassemble my GS550E carb as in the video. When I got fuel/ air needle jets I found someone had taken of the factory plugs. Two of the jets came out with no problems but jet # 2&3 are stuck it there. Someone must have cranked down the needles all the way down. I tried to tap them with a small hammer and a screwdriver, sprayed lubricant and let them sit over night ( the lubricant didn’t even go down the threads, I tried a heat gun and lube .. nothing seems to work. I’m thinking try to drill them out but I know it will ruin the threads but I can always retread them. Any suggestions? Thanks!
I have the same problem and will fix soon thanks for the tips.
I also have a probe with one of the speed needles (mixer screw) What do you recommend?
What type of problem are you having?
It's nice working on something that hasn't been messed with before. That carb looked pretty nasty though.
Yea I guess it was a tradeoff. Virgin carbs but full of varnish. They really were nasty
I have a pristine totally stock 1981 Suzuki GS650L. According to the repair manual it has Mikuni BS32SS carburetors. I have cleaned and reassembled the carburetors. It runs very strong from about 1/4 throttle up. But rough idle. I suspect the pilot jets need to be replaced. Are the carburetors on your GS550 the BS32SS as well? If so where did you get your new pilot jets from? I know you said Mikuni but the only place I found those was from Great Britain. Is there a supplier you found in the states?
It may need adjustments on the mixture screws first to see if it wants more fuel. Check out jetsrus for parts
That r6 tho!!
Service job! Big variety of bikes in and out of the shop 😎
Hey, not sure if you have the time to read this. I understand if you don’t respond but I’m having an issue with my bike. It’s an 81 CM400C. It’s misfiring on one cylinder. Running pretty rough as you probably know. I’ve cleaned the carbs, replaced the floats and float needles. Re-jetted it. They’re immaculate inside! I’ve put on two different sets of coils and wires, currently have a performance coil and wires on with new NGK Iridium plugs and STILL! having the same problem on the same cylinder. I have 150 compression on both cylinders. Spark is excellent! Even installed a new CDI. What am I missing, man??
First, stop replacing parts. That is very important. You must first diagnose the problem before replacing things as you only get further from the answer.
Are the carbs vacuum synced?
Valves adjusted?
Mixture setting correct?
Were the carbs ultrasonically cleaned?
Did you remove the pilots?
You need to confirm the basics first.
Thanks for the reply!
I have not vacuum synced the carbs yet. I’m lacking the tool for that. And the only place that looks like they sell one that’ll work is Dime City Cycles. I don’t have a clear shot at the adjuster screw when the carbs are on the bike though and the tool is a long screwdriver and a hollowed out socket. It looks like I need something angled. I could be wrong though and just not seeing how to do it.
Valves are adjusted to spec in the Clymer manual.
Fuel mixture screws are 2 turns out. I tried 1-2 turns and got a change in the idle but didn’t fix the problem.
Just got them out of the ultrasonic cleaner two days ago and put back on the bike with zero change in the way it was running. HOWEVER! when I drained the ultrasonic cleaner today I saw a square brass fitting and a tiny spring in there. Must have worked it’s way out of one of the carbs somehow. Not sure where that goes 😐
I removed the pilots and cleaner all the fuel and air holes I could find. Jets are clear and the carbs look immaculate inside. Just need to find out where that tiny square brass fitting and spring go and then fire it up again. Any ideas where that thing goes and what I may have done wrong when cleaning them in the ultrasonic?
Carbs are Keihin
Think I found where it goes. In the accelerator pump housing, behind the spring.
@zackfebus7844 you are correct on the accelerator pump cover. Good catch on that. For syncing it is just a bit challenging to do. Check my Amazon Storefront for a basic vacuum sync tool kit.
I too just broke off the flange that holds the float pin. Will try JB Weld. I also am having a hard time finding the really small clip that holds the float needle in place. Of course, without it, the needle valve falls out!. Do some of these carbs use a "C" clip in lieu of the very small clip? Mine is a '79 GS550E, but it has the later square top covers over the slide valve. Can't figure this one out. Thanks for yur series of videos and any help you might throw my way!
Be sure to use JB marine weld and not regular. Many needles have no clip at all as they are held in place by the pressure of the float. There is a tiny plunger within the float needle that helps maintain that pressure as fuel level changes
@@BrickHouseBuilds Thanks for the help. It is the first time I have seen anything other than the float itself to hold the needle in place. The issue of different carbs on the bike has baffled me. I might have a late year bike with newer 1980 parts. Thanks again, keep up the good work.
When I get a key~ I was thinking about checking the gas tank, look around on the carburetors and see if I could start the engine w/o all of this. Any wisdom from you around just starting it up? Can I put something in the gas? I know there are a few things out there I just have never gone there. (95 750 Honda nighthawk 30k miles). Thank you! 〰✨👍✨〰
You will want to try to drain the carbs if they haven't been already via the single screw on the float bowl. With the tank off you can hook a fuel line up to an aux tank. Before adding fuel its a good move to put fresh oil in and rotate the engine off the starter for 5 seconds to help get some oil moved around. Then I'd say go for it. If it doesn't start you can start the diag with it being fuel, air, or spark and see which one is missing
This is gold. Thank you so much. Best wishes always.
@@BrickHouseBuilds
Where did you get that sonic cleaner? Thats massive compared to the one at Harbor Freigh! The HF you have to do one carb at time
It's actually already linked in the description
@@BrickHouseBuilds ah shoot, my bad, I appreciate it!
I just got done tearing a set of these down and the previous owner stripped every single screw by using a phillips head, it was not fun.
At least you can replace them now with what you prefer but yea HUGE difference with a JIS
hello on a suzuki gs 550 with mikuni vacuum carburetor, changing the filters and putting the cone ones by how much I have to increase the jets of the minimum and maximum. originals has 92.5 max and 40 minimum. thank you very much.
There is no exact science on that but likely 1 step on the pilots and 2 steps on the main jets to get in the ballpark. Do not buy cheap Amazon pods. Look for a quality UNI, K&N, or DNA
@@BrickHouseBuilds ok thank you
@@alessandrozecca4437 no problem
I have 1982 Suzuki 1100g and I pulled the bowls off mine it didn’t have the rubber plugs on the Pilot jets is it necessary to have them in it ???
I am not sure if the 1100g had them. You can see if they are required by looking at a parts fisch on a place like partzilla
Why was the one brass rod left in on each? I need to get mine out to replace them
You don't remove those from the carb bodies. You manually clean them and confirm they can flow air through them.
Hey buddy, I was trying the link for harbor freight tool but the link is broken, just letting you know !! .👍
Thank you for the good videos ..✌
Yeah I cant find those trays any longer either. I recently tried to update that link but no luck
@@BrickHouseBuilds quick question my friend, do you have any video on how to replace/repair the see through oil engine level glass.
I have a 2019 Suzuki burgman 400 that is resuming a little bit of oil in that area !!
Thank you in advance.
Best regards..✌
@@eddieg5466 no I do not sorry
@@BrickHouseBuilds got it, thanks for the fast response tho..👍
You didn’t want to replace the o-rings between each carb? You do need to break apart the rack to replace them. There is a guy who sells them on the GS forum
I've used that kit from cycleorings.com and really like them. On these I chose not to split the carb bank apart and the orings never leaked so the decision worked well. Most of the time the carbs go all the way down.
That’s good to know because I have not yet installed mine. Any tips you can give about breaking the carbs apart? I know some people strongly advise against it, but I figured I might as well replace those orings while I got them apart
@@jbo872 hmm, I'm not sure how much info I can really give in a response here. There are many areas to take care with just in regards to splitting them making sure things align and aren't binding when completed. For some carbs you have to disassemble the choke assembly and remove the blades to get the shafts out....the issue is the stalked screws holding them in. You run the risk of damage when removing and they can't(shouldn't) be reused with risk of getting consumed by the engine. The best advice is to take a million detailed photos and visually inspect how all linkages are assembled and how all it all operates. Just pay attention, go slow, use lubricant on the orings, and be methodical
Thanks for taking the time to respond. Between this video and the tutorial on GS forums I feel way more confident getting after it
How do you get the pilot jets out if they get stripped?
Hopefully an easy out
I have a 1983 Suzuki GS550E. Gas is leaking out of the bottom of the left 2 carburetors. The bike only has 4.8k miles on it. Any advice on where to look for a
Floats needles arent seating or bowl gaskets are bad. Mileage doesn't matter as its a 1983 so thats a lot of time
@@BrickHouseBuilds I'll look into it. Thanks!
I know this is an older video but I am having trouble pulling the snap rings for the needle retainers. What size do you use? None of mine fit.
This video is pretty recent actually. I actually have a cheap set of needlenose pliers with ground ends that have a slight bend added to them. You can see me use them during the assembly video of the same carbs.
@@BrickHouseBuilds ok I’ll try that appreciate it.
What model and make is your cleaner?
I actually linked my exact unit below
So how did you, get the pins out , I'm having the same problem?????
Try using a spring loaded center punch
@Brick House Builds I'm having problems with carbs #2,3,4, #1 was no problem I was thinking it's all in the angle, just if there was a punch that could go through all studs...
Definitely DO NOT try all at once. Take your time, use a bit of heat, penetrating oil, and careful force. I'm pretty sure I show how I remove the pins in this
Do you think JB weld would work?
I used a jb marine weld with a pin. I show in detail on Fridays video. Wasn't too bad to do!
How much will u charge me to replace my carbs
Im sorry I no longer do customer work
Velocity stack?
Im sorry I don't really understand what your asking. :/ Will it have a velocity stack?
