Hey, I have to (let) restore a Honda CB600 PC34 Carb... mainly, the rest can I do. But it is totally weak at around 1400 to 1800 rpm, the sound there is not clean onto that, did mean a mechanic. Do you think, such can be a calibration thing? The pre-owner said it was cleaned a while ago, but she was lying about some problems. And I know... internal are as well calibration possibilities, but this should be expensive here...
One thing i learned. Before you connect all four gauges to different carbs you should connect all gauges to one carb to make sure they are reading the same vacuume. they can be off and you'll have to compensate on your adjuster.
well said. no good trying to sync your carbs with gauges that are not calibrated. maybe thats why the mercury tubes read differnt. thats why number 4 was out on both sets. those knurled nuts he was turning on the gauges are dampers to dampen the deflection of the pointers. maybe it would have been better if he put the carbs out of sync then brought them back into sync and done proper demo.
Exactly. I have a four-into-one manifold that I attach a vacuum source to and can calibrate all four at the same time. This is only for the dial gauges.
I know you posted this a while ago, but I hope you see this message anyways. Recently I bought my first street bike. I've only ever had dirt bikes before now, so I've never been familiar with anything but one cylinder. I noticed very bad gas mileage after riding my bike around for a couple of weeks. I took off the carb rack, cleaned everything out, and adjusted the throttle plates. I had no idea what syncing the carbs were until now, after I've already put everything back together. It's such a relief that I did something right, granted without the perfect tools, and adjusted something for the better. Now in hindsight, because I actually know what syncing is, thanks to you, I'm so glad that I adjusted those plates, because they were MILES off a proper setting. Thanks you again so much.
I just picked up a guage set from a guy retiring from boat motor wrenching . It's got about 6 different sets of vac needles all labeled 25 bucks . The carbs you rebuilt for my 78 cb750ss are doing great . Awesome job ! . You said I should sinc them . 2k miles later I will thanks to this video . It's almost riding weather bro , let's GO. Thanks again .
Great Video. I have a 1982 v45 Magna, since 1984. I put it away in 1990 and just started to restore it again. Carbs seized and Shifter rod seized. So I tore it apart. Had the motor sitting there studying it for a year. If you ever seen the carbs for a V45 it would scare you. Looking at you video inspired me. I remember the nighthawks, unfortunately Magnas smoked them. Scared my brother in-law back then. Well Great Video Thanks. I will Show a video of the magna when I start that. Oh, in 1982 the Magna was way ahead of it time, Anti-Dive, Electric Fuel Pump, Water Cooled, Shaft Drive, Hydrolic Clutch and Brake, And probably the best bike ever made in its time. And So fast. Great Video, Your Awsome
I second Kneedown on this. I like seeing a pro doing it right showing detail for people. I spent 10 years as a diesel tech before I went into bridge welding so for working on my bikes I search youtube to get info. Nice to find people giving real info not a cletus hack job. Keep up the good work my man, and keep the bike vertical.
I’ve been using CARBSTIX Mercury gauges for many many years and I love ‘em. BTW on these Japanese bikes those screws that appear to be Phillips head screws are NOT! They are JIS screws, Japanese Industrial Standard which is why everyone strips them out using Phillips head screwdrivers. Excellent work BTW and I believe I’m going to get a set of those sync gauges, you’ve convinced my 60 year old self!🤘🏼
What a find! Yes its from 2016 but this is the cool thing about YT. I've been working on bikes for 30 years now and this is, by far, the clearest explanation yet. I've got this to do, just rebuilt the carbies on my 1985 GS850, she starts, idles with a fart and a pop but isn't pulling much above 3000rpm. Carbs were bench synced only so I'd expect nothing less than dog rough! You're a gold mine, if only to confirm what we know (or thought we did!) Love you man.
Cody I bought a 1980 cb900 it has a gsxr750 engine fitted its been sitting in a shed since 2001 carbon were full of jelly your video's are great all I need to know to get jobs done never had any trouble with cars till I bought this all the best keep making great informative video's
Mate, absolutely brilliant video. The comparison between vacuum and mercury was interesting, and a full description of why and how was invaluable, I am now a subscriber.
If you calibrate the gauges to each other they will have more accuracy. All you need is a syringe and 4 port manifold to create a common vacuum, then use the calibration screws on the affected gauge. Best to pull the vacuum to the normal operating value during cal-in your case around 20 cm/hg. The cheap Emgo gauges have a cal screw under the glass. If the gauges don't have adjustments then note which are off or mark the bezel for error correction. You also need to dial or damp more bounce out of all the gauges.
if you calibrate them on a monday - you will have 6 more different calibrations by Sunday, if you calibrate them at 1000 revs they will be out on 1500 revs - if you use seperate dial gauges you will never know.....but in truth this isnt about accuracy - it is only about getting them into the working zone.....at best.... but lol on the damping - you tell me what you want them to read and i will dial in the damping and all unequally on every gauge.......
The best I have found over the years for dampening the gauges are iv drip emitters from the medical industry that go on the vacuum lines Between them and the valves on the gauges 0 bounce
Best video I've ever seen on teaching someone how to sync carbs! Put out an entire series of videos! Your direct, to the point and don't mess around with "so now I'm gonna loosen this screw...that's just not coming off is it" stuff. Thank you for such a professionally done video!!!!
Awesome video. My english isn't that good but I understood nearly everything. If your not already an instructor you would be one of the best instructor ever. I wouldn't hesitate to take lessons. I immediatly subscribed to your channel. Thanks!
I bought a 73 cb750 that had been parked for 43 years. Oil down the cylinders, carb clean, oil change, new plugs, air filter, cleaned points, got it running. It ran poorly, so I removed the carbs again and found a drill bit that fit nicely under one carb slide that I knew was working well. Adjusted the other 3 to match. Voila! I was riding! But a little sputter just off idle, where I do most of my riding bothered me. I built a manometer. Got them adjusted really close to the same. Now it actually runs a little worse. I'm buying some gauges today (quality used ones) and gonna try it again.
Definitely not wasting my time. You are very thorough in your explanation. Much better than any video I've seen so far. But got only question. Shouldn't the valves be adjusted before this procedure? Brother keep up the great videos.
Not sure if I have left a message previously or not. But thank you for taking the time to do this video. It takes a lot of work to do it. Greetings from Western Australia.
Fantastic info. You saved me from buying a synchro kit for a recently purchased 1985 VF1000. After cleaning the carbs, everything ran better than Imagined.
Hands down the most informative and professionally made motorcycle mechanics videos on the web. You def need your own tv show. Keep up the good work, im learning more from you than a combination of multiple other people combined. Great work bro, keep em comin.
what I learned how you easily set the sync without gauges is: remove the carb-bay from your bike take the smallest drill you can (one that is not grimy nor with burrs) get mark one side of the shaft with a Edding(or whatever permanent marker you can get) for repeatability of the position for the next step: BE GENTLE! using force might damage your carb fataly open the butterfly by turning the RPM screw in, so that the drill will juuust fit between the "Master"-butterfly and the carb-body with the mark facing up (make notes for the turns on the RPM screw) repeat with the "Slave"-butterflies so that the drill will juuust fit underneath those close the RPM screw back to normal by screwing it out insert the carb back into your bike and take a ride to warm up the engine adjust the idle to spec RPM
I love this video. You went over how the carbs work, how to fix it, and what are things to know. How you explain things, in order and what to watch out for is awesome. You answered questions i didn't even know i had, and things like the base carb, never knew existed. But that makes sense. Awesome video, Instant sub. Keep doing what your doing.
I drop a stupid port screw and washer down into the middle of the engine /EVERY/ time I do this. They are such a PITA to get back!!! New subscriber here and wanted to say you did a very nice job with this video. I noticed you have pods. I have a 93 CB750 and I know the reputation Nighthawks have running with pods. It demonstrates to me you really know what you're doing. Keep up the good work - really happy I stumbled across your channel.
You explained the procedure well and I like that you showed the difference between both style tools to check the carbs. Everything was clear to see in the video. Thumbs up
Best instructional video ever, well presented, no unnecessary talk, great style , fantastic information. Told me everything I needed to know. Keep it up!
Thanks for making this video. I’ve learned more in this video in regards to carb adjustment and different types of gauges than I have in any other video on here.
Depending on how the carb vacuum layout is you can have 2 banks of 2 carbs instead of 1 master carb. Keihin FCR's are like this. Carb 1and2 are tied together and 3and4 are ties to gether. With port linking the 2 banks of 2 together. You make 1&2 the same, 3 & 4 the same then bring both pairs together with the center spring screw.
This is the first vid of yours I've watched. It's given me a start on what I should be looking at with my G1 6R Ninja dying on me. Thanks for sharing your expertise. It's invaluable.
Just wow, I’m new to bike and have made a silly mistake with a bad manometer, hopefully my bike will survive the water manometer it sucked it in! YUP! Any way draining the oil and pulling the plugs for a few spins and hopefully I’ll get away with it !!!!! I’ve watched lots of online videos but NONE come near the quality and content of this one here. I have just subscribed and this will be my come to place to learn more IF my bike has survived.
Great editing Cody! The reason for the difference in the vacuum vs. mercury is the vac gauges need "sync'd" to each other before use. I do it every time I use them. I can share the link to my video on doing that if you'd like. Also note, the Mercury gauges need "sync'd" too. Its common the many folks (not looking like you do) store the gauges on their side and little by little small amounts of mercury (or the later used blue fluid) separate of leak out and cause you to think the carb are out of sync. The big point here is your carb sync is only as good as the gauge sync. Keep Wrenching pal...H2W
G'day from Australia Beautiful non-bullshit video, well done. Only thing I'd have added is an explanation about the base carb being directly connected to the throttle cable and is where the the idle speed is adjusted. Great stuff, thanks
Good clear information thats why i subscribed . What would cause number two carby to flood cylinder, even when engine is running fuel is leaking out exhaust manifold . Fuel is also getting into the engine oil and raising the oil level within 5-10 minutes running time. I have checked floats on all 4 carbs ( multiple times ) new jets new inlet rubbers new hose clamps carb bodies cleaned ( multiple times ) . Its a 1981 gsx 1100
Good video 👍 where did you get the extensions for your pod air filters and I'm assuming it's a better setup than just putting the pods right on the carbs. I have a 1982 CB 750. Thanks
I measured how far I wanted the dimensions and size of the tubes. Ordered them pre-cut, raw aluminum from online metal place. Polished them myself and installed.
Great video. Thanks. I have a 1982 cb900c. Just cleaned and did all the assy. But see 3 and 4 are running too hot and if I feed more gas it revs to 5k. Then goes. So I need to go to #2 and adjust 3 and 4. ?thanks
Awesome video! Watching this video gave me the confidence to sync my 1981 cb750k. I too have the mercury gauges, and I wondered which gauges were better. You answered that question, and more. Thanks!!!
Cody thank Yoxford your video's they have helped me sort my bike out in stages now getting it ready for mot just wiring and odds and sods to do you demonstration on the balance gauges has given me the know how to set them carbs up to get them close I used a sewing needle to get them close as it was really rough to start with and wouldn't idle now it idles to place gauges on to balance keep the videos coming regards mark
So great video thanks. Now I may have missed this but shouldn’t you disconnect each of the carb linkages prior to doing the adjustment to make each carb independent. Just asking
Lots of good info here man. I've come from 4wheel land where a two wheel friend wants me to rebuild his carbs and get his bike running again and I'm just going and researching everything I may need to do. So thank you. 👍🏻
hey man, just wanted to let you know that you present information is great. straight to the point and has warnings. my view was just a random click, but i will be viewing more videos and subing to your channel. keep up the good work.
Hi there , thank you for sharing your knowledge about carb synchronizing, can you please do a video on synchronizing carbs on a GL 1500 Goldwing . Thanks
Good info. How does the hawk run with the pods and velocity stacks on the CV's? I have a 91 cb750 im working on and was reading about the CV's being hard to tune with pods.
Thank you. Would it make sense to connect all 4 dial gauges together to same vacuum source and then adjust them to match each other before connecting them to their individual intakes?
Can you do a video for your pod setup and tuning. I have a 79 cb750f put pods and jetted the carbs. I sync the carbs and ran thru for vac leaks. But I noticed you pipe your pods. I like to know more about that setup.
Same here I want pods for a cafe racer look so get rid of the bulky airbox but apperantly cv carbs don't like pod filters. I don't care about the noise or power just want cleaner look!
@@Tryant69 I've found that CV Carbs work better with Unipod filters vs the pleated/KN type pods filters...it's a smoother airflow as the slides use this airflow to move up/down. Alternatively, you could add tubing, or better yet velocity stacks, to the back of the CV carbs and then add the pleated style air filters which will help to smooth out the airflow.
@@ticosandoval first thanks for you reaction! But unipod? Do you mean like the cilinder shaped foam filters instead of the paper+mesh pod filters? I was thinking about cutting the original box to only keep the mount and velocity stacks and then fit one big foam filter over al 4 stacks. Was hoping that would work.
great video question on where to hook up hoses . on my manifold i have four ports .I also have a vacuum port on carb two witch to petcock hooks up to . do i use the four on the manifold or three on the manifold and the second hose to the carb its self thank you
thanks Coddy,for your involvement in helping us with our bike,my question is did you ever do this on an old GoldWing like my GL1200 1984?? i need guidance.Thanks gervais
love your vids mate, it looks like the old school mercury sync gauge is more accurate than the new gauges. As mercury is a substrate that can't be altered, it's automatically in calibration, and perhaps the gauged calibration setup has gauges that could possibly be out of calibration? But as you said, you can get the synchronisation in the ball park with close tolerances.
great video bud cheers been sorting my own bikes for years never too old to learn new things picked up a tip with the snapping back the throttles simple trick but makes so much sence ;-) Respect fella ride safe
Great tips, Cody! I am wondering, will the 4 gauge tool work on a dual carb motorcycle? Can you leave two gauges disconnected or is there anything that has to be done on the 4 gauge tool before it's used on a dual carb machine?
great job I have question i have zg1000 do you have a take apart carb demonstration rebuild for that model ? I bought car the engine blew up was not told it was bad they somehow doctored it . so i needed a transportation and bought a bike to find out the carbs are bad . sooner or later something good should happen. any advice would help thanks
Hi, I am really happy you made this video! And I understand that you have the Knowlege!! I Have just started a project building a Junior Drag Bike for my son, and are just now working with the Carburettors to get them to work. This is really helpfull!!
Excellent video, it should be watched by all who fear multiple carb setups. It would be great if those gauges had some sort of internal damper to stop the oscillations.
I know I’m years behind on the party but I just want to let you know this is a great video. I can’t find anything that says my ‘77 Honda CB550F has a specific carburetor for which I’m supposed to set the rest. I noticed yours was carb number two. Do you know if there is a specific carb that I’m supposed to set first? It looks like all of my carbs have an adjustment screw on them
I got my first junker and I'm restore the 91 Suzuki GSF 400 so I got a lot of questions,first being how to tune the carbs for economy but have her leaning a little to the 'rich' fuel mixture side. Secondly does replacing the default air filter box for individual sports air filters add more air making run even leaner?

Definitely useful info here, short and sweet too, carb balancing has been a mystery to me for years but after watching this it makes total sense
You are a life saver. I am restoring a mid 90's Ducati and was looking everywhere to find where to attach my synchronizer!
this guy is like a service manual for me. best information and tips
Hands down the most informative and professionally made motorcycle mechanics videos on the web. You def need your own tv show. Keep up the good work, im learning more from you than a combination of multiple other people combined. Great work bro, keep em comin.
what I learned how you easily set the sync without gauges is:
remove the carb-bay from your bike
take the smallest drill you can (one that is not grimy nor with burrs) get mark one side of the shaft with a Edding(or whatever permanent marker you can get) for repeatability of the position
for the next step: BE GENTLE! using force might damage your carb fataly
open the butterfly by turning the RPM screw in, so that the drill will juuust fit between the "Master"-butterfly and the carb-body with the mark facing up (make notes for the turns on the RPM screw)
repeat with the "Slave"-butterflies so that the drill will juuust fit underneath those
close the RPM screw back to normal by screwing it out
insert the carb back into your bike and take a ride to warm up the engine
adjust the idle to spec RPM
Great video. I guess we all have things we hate doing, this has always been one of mine, carb sync and spoking a wheel.
This guy knows his stuff. I've always used the mercury gauges. he gets it right.
I love this video. You went over how the carbs work, how to fix it, and what are things to know.
How you explain things, in order and what to watch out for is awesome.
You answered questions i didn't even know i had, and things like the base carb, never knew existed. But that makes sense.
Awesome video, Instant sub. Keep doing what your doing.
Thanks man! 🤙🤙
dude. amazing video. totally understood everything the first time youwent over it and was able to sync up the carbs on my 1993 nigthawk

Love the video MC MD. The clear no nonsense step by step tutorial is great, really makes it seem not so intimidating.
This is by far The Best Video For Carb Sync!
Thanks a lot!
G'day from Australia
Beautiful non-bullshit video, well done. Only thing I'd have added is an explanation about the base carb being directly connected to the throttle cable and is where the the idle speed is adjusted. Great stuff, thanks
You sound so knowing what you do you get yourself a follower
This is exactly what I have been looking for. Even better is that it's the same bike that I've defiled for my own project.
Good clear information thats why i subscribed . What would cause number two carby to flood cylinder, even when engine is running fuel is leaking out exhaust manifold . Fuel is also getting into the engine oil and raising the oil level within 5-10 minutes running time. I have checked floats on all 4 carbs ( multiple times ) new jets new inlet rubbers new hose clamps carb bodies cleaned ( multiple times ) . Its a 1981 gsx 1100
Good video 👍 where did you get the extensions for your pod air filters and I'm assuming it's a better setup than just putting the pods right on the carbs. I have a 1982 CB 750. Thanks
I measured how far I wanted the dimensions and size of the tubes. Ordered them pre-cut, raw aluminum from online metal place. Polished them myself and installed.
Thanks man. Appreciate the info 👍
Great video. Thanks. I have a 1982 cb900c. Just cleaned and did all the assy. But see 3 and 4 are running too hot and if I feed more gas it revs to 5k. Then goes. So I need to go to #2 and adjust 3 and 4. ?thanks
Awesome video! Watching this video gave me the confidence to sync my 1981 cb750k. I too have the mercury gauges, and I wondered which gauges were better. You answered that question, and more. Thanks!!!
Excellent explanation and tutorial. Could not be more complete. Congratulatons!
Your videos are amazing ! Thanks for what you do and being on point without any carry on , love ya work mate ! Learning lots from your videos.
Great production value and teaching. I'm watching a bunch of your videos right now and learning so much!
Cody thank Yoxford your video's they have helped me sort my bike out in stages now getting it ready for mot just wiring and odds and sods to do you demonstration on the balance gauges has given me the know how to set them carbs up to get them close I used a sewing needle to get them close as it was really rough to start with and wouldn't idle now it idles to place gauges on to balance keep the videos coming regards mark
So great video thanks. Now I may have missed this but shouldn’t you disconnect each of the carb linkages prior to doing the adjustment to make each carb independent. Just asking
Absolutely superb demonstration of spot-on, detailed, and pertinent carburetor synch process. ++Awesome++
Your mechanic skills are fantastic, but your teaching skills are beyond excellent. Keep up the great work!!!
Lots of good info here man. I've come from 4wheel land where a two wheel friend wants me to rebuild his carbs and get his bike running again and I'm just going and researching everything I may need to do. So thank you. 👍🏻
hey man,
just wanted to let you know that you present information is great. straight to the point and has warnings. my view was just a random click, but i will be viewing more videos and subing to your channel. keep up the good work.
Thanks man, learned about this in school but needed a refresher, gotta sync 3 carbs on a Honda outboard
Hi there , thank you for sharing your knowledge about carb synchronizing, can you please do a video on synchronizing carbs on a GL 1500 Goldwing . Thanks
Brilliant video mate. Would have been nice to see what happens when the other adjustment screws weee moved. Some great points though 👍🏻
Except tutorial , I’ll be doing mine today & you just took any worry out of it. Having never done this on a bike before.👍🇨🇦
Your video is the best.I will use your advice when I synchronizes my carbs today.
Good info. How does the hawk run with the pods and velocity stacks on the CV's?
I have a 91 cb750 im working on and was reading about the CV's being hard to tune with pods.
Easy listen to instructions and simple instructions, I’ll definitely be giving it a go . Cheers man
Best video / tutorial on carb syncin I have ever seen! Thanks for your effort!
Thanks man!!
Thank you. Would it make sense to connect all 4 dial gauges together to same vacuum source and then adjust them to match each other before connecting them to their individual intakes?
Such an informative introduction alone
This is the best video I have ever seen ! Outstanding information, thank you
Can you do a video for your pod setup and tuning. I have a 79 cb750f put pods and jetted the carbs. I sync the carbs and ran thru for vac leaks. But I noticed you pipe your pods. I like to know more about that setup.
Same here I want pods for a cafe racer look so get rid of the bulky airbox but apperantly cv carbs don't like pod filters.
I don't care about the noise or power just want cleaner look!
@@Tryant69 I've found that CV Carbs work better with Unipod filters vs the pleated/KN type pods filters...it's a smoother airflow as the slides use this airflow to move up/down. Alternatively, you could add tubing, or better yet velocity stacks, to the back of the CV carbs and then add the pleated style air filters which will help to smooth out the airflow.
@@ticosandoval first thanks for you reaction! But unipod? Do you mean like the cilinder shaped foam filters instead of the paper+mesh pod filters? I was thinking about cutting the original box to only keep the mount and velocity stacks and then fit one big foam filter over al 4 stacks. Was hoping that would work.
@@Tryant69 Yes, UNI filters: unifilter.com/ vs. the pleated kind like K&N: or other folde style. Not sure about your concept, but might work?
Yep, some old dudes from yesteryear used to sync with a piece of tubing by ear and good at it too
great video question on where to hook up hoses . on my manifold i have four ports .I also have a vacuum port on carb two
witch to petcock hooks up to . do i use the four on the manifold or three on the manifold and the second hose to the carb its self
thank you
thanks Coddy,for your involvement in helping us with our bike,my question is did you ever do this on an old GoldWing like my GL1200 1984?? i need guidance.Thanks gervais
Man, this video is awesome, so simple explained, so clear.
Congrats.
New suscriber here.
You can still use the vacuum to get your pilot air screws to a good baseline or as a sanity check if you're investigating a rough running engine.
love your vids mate, it looks like the old school mercury sync gauge is more accurate than the new gauges. As mercury is a substrate that can't be altered, it's automatically in calibration, and perhaps the gauged calibration setup has gauges that could possibly be out of calibration? But as you said, you can get the synchronisation in the ball park with close tolerances.
This is at least the third time I've watched this. Great content. The royalty free music though... it's loud in some parts of the video
just finalizing my bandit 400 carb effort. Many thanks, really helpful!
you sound and look like a really cool guy to have around! and your videos are way more informative than any other ones I saw on YT so far, Thank you!
great video bud cheers been sorting my own bikes for years never too old to learn new things picked up a tip with the snapping back the throttles simple trick but makes so much sence ;-) Respect fella ride safe
Fantastic video. Explains everything perfectly.
Great tips, Cody! I am wondering, will the 4 gauge tool work on a dual carb motorcycle? Can you leave two gauges disconnected or is there anything that has to be done on the 4 gauge tool before it's used on a dual carb machine?
great job I have question i have zg1000 do you have a take apart carb demonstration rebuild for that model ? I bought car the engine blew up was not told it was bad they somehow doctored it . so i needed a transportation and bought a bike to find out the carbs are bad . sooner or later something good should happen. any advice would help thanks
Hi, I am really happy you made this video! And I understand that you have the Knowlege!! I Have just started a project building a Junior Drag Bike for my son, and are just now working with the Carburettors to get them to work. This is really helpfull!!
baklys So glad I could lend you a hand on the build with knowledge! Have fun with the build! I would love to see pictures when it's all done!
Great video i have a Suzuki gt750 could you show a video of a carb setup with the original setting
Excellent video, it should be watched by all who fear multiple carb setups. It would be great if those gauges had some sort of internal damper to stop the oscillations.
I know I’m years behind on the party but I just want to let you know this is a great video. I can’t find anything that says my ‘77 Honda CB550F has a specific carburetor for which I’m supposed to set the rest. I noticed yours was carb number two. Do you know if there is a specific carb that I’m supposed to set first? It looks like all of my carbs have an adjustment screw on them
How and when is a air/fuel ratio mix adjusted?
I got my first junker and I'm restore the 91 Suzuki GSF 400 so I got a lot of questions,first being how to tune the carbs for economy but have her leaning a little to the 'rich' fuel mixture side.
Secondly does replacing the default air filter box for individual sports air filters add more air making run even leaner?
