- Removal and rebuild of carburetors on 1980 1981 and 1982 Suzuki GS1000G Carburetors. This bike uses two different sets of carbs depending on model. This video works with the Mikuni BS34SS carburetors.
Does not include drilling and removal of air mixture screw. I was going to cover that in a second part to this video but the footage got corrupted and I will have to re-shoot when I have another set of these carbs in.
this seems pretty similar to my gs750e 83 carb, ill have to double check, but this looks promising. very detailed, and good camera work my guy
Just got my brothers 80 gs1000g. He passed away in November at the age of 40. Bike has been sitting for 15 years so I'm gonna start restoring it. I have tons of memories on this bike with my brother. I may have to message you for some help 😃
Man I'm sorry for your loss... That's way too soon! Definitely message me with any issues and I'll do my best to help!
@@MotoMedic thanks. I miss him so much. He always wanted to restore this bike. We used to ride it all the time back in 04-05. I've got a rebuild kit for the carbs. I should be able to handle that. I'm not sure how to sync them though. Do i need a special tool?
@@joshsutcliffe6099 you can use a small feeler gauge or even a guitar string to bench synch each butterfly valve. It'll get you where they're at least all the same, then fine tune from there, or go pick up a synch tool and watch a few videos on how they work... Helps having the service manual for that.
@@MotoMedic ran in to some trouble on the rear brake lever. It has sit so long that its seized up. I've tried heat,pb blaster,pry bars and jumping up and down on it...to no avail. Do you have any ideas? I was wondering if it could be pressed out and replaced or cleaned.
@@joshsutcliffe6099 I'd do whatever I could to get it off of the bike and throw it in a vat of solvent or maybe even let it soak in some lightweight oil.
Or chuck it in the old bin and hit eBay for a replacement! 😁 Good luck man!
4 separate carbs, holy sh*t
I see you didn't remove the float assembly pivot pin on camera...it's a difficult procedure. Pin impact tool is helpful there, as it's easy to break stanchions. Looks like a screwdriver with a sharpened end, you push, it loads pressure, lets go and knocks pin out.
@@davidkettlewell829 they don't always work as easily as we assume. Scroll my page to find the video where I had to drill one out because it was fused in after sitting for so long.
Had a 1978 GS1000. Never did the carbs on it. It was new when I got it, and I sold it a couple years later. Had a 1980 KZ1000 and did the carbs on it. I'm not a mechanic but I am pretty good at following instructions.
Great video, thank you. I need help, and I have a question if I may bother you?
I am rebuilding the same carburetors on the bottom side of the carburetors where you put the Jets in and the needle and seat in. In fact directly on the other side of the carburetor from where the needle and seat is, there is a hole with an aluminum plug in it.
I think these are called Welch plugs, the set of carburetors I have are missing one of these plugs, and I'm having an extremely hard time trying to find the right part or even the part number do you have any advice? Please 🙏 and thank you
Due to these being such an old bike I'm not sure where I'd know off hand. Start maybe at www.partzilla.com and see what they have. If discontinued... copy the part number and paste into a search on Ebay. Might get you what you need!
U NEED A MAGNIFYING GLASS TO CHECK NUMBERS,DIDNT REMOVE NEEDLE JET,AND FLOAT HEIGHTS.
Didn't need new needle jets. Yes I should have checked float heights. Got lucky and bike ran great. :)
Great video; I'm pretty sure I'm buying a 1000 gs tomorrow, wish I could had seen you set the float height, have to look for another video somewhere on how to do it.
I wish I would have done one!
Did you buy it?
No sure why you did not show removal of float pin...they are hard to get out. How did you do it?
@@davidkettlewell829 it's been so years since that video so I'm sure I got it out with curse words and alcohol.
dumb question are these carbs the same as the 1981 suzuki gs650g?
Most likely they're not. Chances are the carbs on the 650 are a bit smaller. But I would have to cross reference the two bikes to know for sure. All available on the internet if you wanted to do some snooping :)
Cómo puedo saber si está inyectando combustible ya que los míos no lo asen ya los lave y todo párese bien
Hello I have a 1980 Suzuki ge1000 it only has 3 lines coming from the carbs I can’t find the main fuel line I don’t know what happens to it I bought the bike for 800 dollars from an old man he said he bought it and never used it
Dude where is "Replacing the CV carb air screw and card sync" video as you promised at the end of this video?
Running a shop with 15 bikes to work on got customers means not every job gets recorded. It happens. I wanted to... I just didn't get the time to.
So my issue right now on my 1982 GS850GL is that:
1) the T-joints are leaking fuel. Should I just purchase whole new t joints from partzilla for $20~$30 each or is this an o-ring package that will do the trick.
2) the bike only runs on starter fluid, I figured the jets might be way too lean since I haven't rejetted since I put pod filters on, but I wasn't sure if it could be related to something else I didn't know about.
Answers to both would be a hard yes.
For that cheap might as well replace the T joints. I think they might even come with O rings but might as well get new ones there too.
Probable on that 2nd question. Always rejet when going to pods for sure! You're getting so much more oxygen that you were.
You forgot to take out the needle jet under the main jet to clean it.
If you can see daylight through a main jet there's no need to take it out and blow air through it but yes.... I didn't do that one in this video.
Wide open my 80 falls on its face. Other than that it runs ok. No air leaks. Think it's a main jet? Also how do I richen it up since these carbs have the air mixture screw instead of the fuel mixture screw.
falling on its face could be from already being too rich, if it backfires it could be too lean. Not a motorcycle mechanic but general carb knowledge
Are the same carbs as the 80s Honda cb900c? Can ya put pods on them with out to much hassle?
They're probably similar but not exactly the same. You can put pods on them, yes, but you'll want to re-jet the carbs since you'll be pulling much more air going to pods.
strange question, i have a 1980 gs1100e and i can not find were the fuel vacuum line goes to on the engine its had a new tank and not running right, usually there is a nozzle on inlets but these are all capped off is there a vacuum on the engine do you know. Its having my life right now haha
Did u figure it out brother!!??
Do you know where i can get fuel tubes for a 78 gs1000. I have a "T" but need to the 2 straight pieces. Would buy a bunch i have 2 78 1KE, 2 79 1KE, a 79 L model and 3 gs750s. Will be starting on getting them up to date soon.
First place I would start is Ebay... then start hunting around on forums that might be dedicated to these old bikes. You might find someone who has some.
I need some help man. I bought a 1980 Suzuki gs1000g as a project bike. I've rebuilt carbs and I'm trying to put all of the lines back together my issue is I have 4 ports on the carbs and 3 on the tank. I didn't undo any of the lines so I have no idea what line goes to what port. Any help for this?
Two of the ports, the ones in the center goes to the petcock itself, ones a vacuum and one is the fuel line. The third nipple on the tank is for overflow from the pump, it along with the two side ports just have hoses aimed at the ground.
The fuel gauge*
I have a 82 gs650. I can't remember where the line coming off the fuel sending unit goes. I think it's a breather routed to the bottom but I was wondering if you might be able to give me some direction
If I remember right I'm pretty sure you should have the main fuel line and a vacuum line going to the petcock. Vacuum line goes onto the smaller outlet and connects to carbs. The vacuum sucks fuel into the main line when the bike is running.
So the other two lines coming off would be breathers? I’m in same boat I only see two line hook ups but I feel crazy sense there’s 3 extra lines after that
I have as GS 1000 that I need to do this to. I am changing the original exhaust to a 4 to 1 Vance & Hines exhaust and I need to re jet it. What size jets should I use?
I don't know off hand what size jets you'll want to use. But what I would recommend is either the Dynotjet stage 1 or stage 3 kit. Depending on whether you're staying with stock airbox or not will determine which stage to get. If you're running pods, you're going to want stage 3. Stock airbox, stage 1 probably will get you done. But make sure you order make and model specific.
@@MotoMedic The airbox had already been removed when I bought it. It has pod air filters on it now. Thanks!
Why did you show how full of crud the float bowl was, then set it aside and proceed to call the float itself the float bowl 4 times in a row??
Who knows... Make a better video so people don't have to watch this horrifying garbage. 🤙🍻
Hey I'm working on a 1980 gs850gl having major problem I rebuilt all four carbs new parts an 3/4 still puking gas every where any suggestions
Did you double check your float heights? Sounds like it's just getting too much fuel and not closing off the supply. Float height being wrong can do that. Also check the float valves are seating!
hey i'm working on a friends 1980 gs 850. im having such a hard time figuring out the throttle cable to the carbs. they're so loose and i can't get them to tighten up for that snap in the handle. do you have any tips for an adjustment?
So there could be a couple of problems. First is that maybe the cables are just too worn out to get adjusted. Second and more likely... They're not the correct cables for that bike. Usually even work throttle cables will work, but if they aren't the right ones you'll fight with them.
Moto Medic You very well may be right. Nothing on this bike seems to be working for me lol
How did you remove the float pins??? You just cut the video and your float was out hahaha. Mine are stuck!
Oh you're right! I never explained that! I ended up taking the carbs off of the rail and getting each in a vice (gently). Then nicely tapping them out with a small punch and some patients. Eventually got a small vice grip on the pin and pulled.
@@MotoMedic You rock. Unfortunately my rail screws are all stripping, so I need to do the Ol' drill and torque key them out trick. Thanks for the advice!
@@nightkast0 I highly recommend an extractor kit. 👍👍👍
I am doing a rack on a gs1100 1980. Use a pin punch and a small,small hammer.
I would suggest using a vice with soft jaws to hold the rack.
I do this for a living.
why not replace the needle jet behind the main jet
Because needle jet was not in bad condition. I didn't feel it needed replacing.
I can't seem to find part 2, which is the parts of the bike I need video on.
Unfortunately I had some video get corrupted making the second part and haven't had another GS in to finish the series. Happy to answer any questions if I can though.
@@MotoMedic im having trouble figuring out what the clip, washer, and rubber o ring that are in the small pack in the rebuild kit go.. Cant tell whats what in the manual.
@@devindarwin9878 if it's a small circlip it's probably for a new needle if your kit came with one. A really tiny washer, spring, and O-ring are likely for the air mix screw, which is most likely not visible on your carbs unless someone has already done it. They have a small cap that you have to drill out to get to the mix screw. That's what I wasn't able to get in part 2!
@@MotoMedic thanks man. Hurry up and find a set for part two lol. I'll lend you mine for free...lol.
@@devindarwin9878 lol... If you're in Spokane Washington I'll be there by next month
Are all parts for true carb the same
What does this phrase mean...???
WTH! You did not show what you pulled out or replaced, close up so we could see
Dam.
These videos are to help. Not to show every little detail. That's what the service manual (the thing I'm using to know how to do the job) is for. Download it and use it to do this job.
Camera angles little difficult , other then that
You just skipped the air fuel jet!
Yeah... I sure did!
Where did you get the rebuild kit?
I believe I got this kit from All Balls Racing.
At 3:35 lmfao cause I'm sure alot of ladies are watching a video on how to remove carbs from a Gs1000 lol
Hey bro... You just never know. Not that it matters anymore because that beard is much shorter and I've got a rad girl so I guess it didn't work anyway 😂
Need yoy help please.
Please elaborate
@@MotoMedic My English is not very good, I hope you understand me. I saw the carburetor when he took it off his motorcycle, my question is if there is something else connected to the acceleration cable. My motorcycle does not want to start. Could you show me a picture of how it looks correctly? I've looked for it on the internet but it doesn't exist.
