I have spent 20+ hours trying to get my dirt bike to run, trying to learn carbs. This video is a godsend and now my bike is running right!
Thanks for the explanation of hanging and high idle slowly returning to normal being a lean condition, and low idle creeping back to normal being a rich condition. These types of tips bring it back to the basics and make it much easier to understand. Much appreciated.
Yes this is the one we’re looking for. Couldve started the video from 7min onwards
Excellent Instructions keep on teaching

Hanging also can happen from a leakage on intake parts
Very thorough and informative. Thanks🤘
I am 74 years old and have doing it for 55 years. It works exactly like that for cars as well. We call it the sweet spot.❤🎉
I’m 72…you’re the old man with the wisdom…I’ve been working on motorcycles since 72….not quite as long (lol) but you’re absolutely right! Worked on my ‘72 gto in ‘72…..
I learned to tune carbs from an wise old man in 83 just after highschool. Works for any carb I have ran into since.
Yes sir!! Just finished tuning my '67 Mustang GT!! I upgraded the exhaust and changed the intake so it needed tuning.. got it right to the sweet spot once I figured out the electronic choke issue I was having.. I'm about ready to fuel injected with the Holly system!!

@@michaelneighbors9047just know that not all carbs are the same. I use to think i understood how to do one. Then ended up with a 4mix sthil weedeater which is entirely diff from the 1½ turns each and walk em in from there i was taught on most any other 2cycle.
Holy crap I'm 67 years old and I finally learned how to tune a freaking mikuni. Thank you very much you don't talk too much you talk just right and tons of information. Again thank you very much I'm a subscriber now
Couldn’t agree more
I don’t think you talk to much. I find your descriptions extremely helpful. One of the reasons why I watch your videos. The explanations are great and so helpful!
Agree!
I do think you have too much to say, just get down to the job in hand. Thanks.
I concur. I'm a d.y.i type of person. Love the way/why you explain things. Stay blessed
Very well explained, eventually, but no need for the: "I Will be talking about this and this and this". Nevertheless, thank you very much!
Great video, just rebuild my carburettor and upjeted it for i fitted a open air turn out exhaust, could not find my colour tune so fallowed you instructions to a T and bike is running perfectly. Also what would your options be on using the colour tune ? Do you think they are any good?.
Cody, you’re not talking too much. The person that would make such a comment has both an at attention span of one minute and a motorcycle that runs like crap. Keep up the good work.
Really Means a lot man thank you for that encouragement

Hi bro u got any vids of doing carbs on a 87 honda magna or any thing similar 4 carbed
I fully agree. I can see that you would be a great instructor! Dean Retired Teacher
Actually, he rambles on and on
Great advice, clear for those who just want to tinker at home! One note however; As a bike mechanic I've always been with the understanding that once you've found that sweet spot where the engine idles at it's highest, we should go clockwise 1/8 - 1/4 of a turn to make the mixture is ever so slightly rich. The rpm will still drop back great to idle (you wont notice), and it's a general rule of thumb that a teeny bit too much fuel is better than a teeny bit too much air. It keeps everything a little cooler. Engines always run most efficiently when running slightly lean (also in terms of power output). The down side of this of course is that it produces a more risky, hotter combustion. We don't need maximum power efficiency at Idle, and for this reason it's better to always adjust that 1/8-1/4 turn in. Keep up the good work!
Maybe if the ignition is strong enough at idle. Can also foul plugs and soot things up so I like to go a little lean at idle as a result. Not much. There’s so little fuel at idle and no load, so the lack of the extra piston cooling won’t matter.
@@desmo8755 At summer temps of 100+ stuck at stoplight in traffic, with air cooled engine, I'll take every bit of possible engine temp reduction i can get
@@draizwrm I hear you but it’s funny because I go a little lean because I don’t want the engine to load up … mainly for hot days idling. Depends on the machine and ignition I guess. I have a couple of old bikes and especially 2 strokes that do not like a rich pilot circuit. They may run OK for a while and cold-start well but the plugs will start getting dark if they’re idling on a summer day. Would be interesting to see how much hotter a lean burn causes at idle. Under load lean is bad, for sure, but I suspect the engine temp doesn’t change much with a lean idle. I might probe one sometime and see. And all my stuff is air cooled even an old beetle so I totally read you. If you have any test info or something let me know.
@@desmo8755 I can understand your reasoning on two strokes, i used to buy and sell little Honda 2 stroke bikes, generally the exhaust would be clogged with carbon , the sparkplug fouled, my bike is four stroke, a 2009 i bought in 2011 from the first owner, it hasn't seen an open highway in several years, it does see urban city traffic everyday , it is my primary mode of getting around town, i have no test data, or reference links
I always thought that if it’s running lean at idle then it would run lean at full power. Throttle and mixture control are two different things.
Cody your detailed description is perfect for me, ive listened to so many & still have to pause play pause play whilst im working on my bike. I was starting to think ive got a problem until i watched one of your videos on carb tuning & it was perfect, so thank you great work...
I've always struggled with adjusting the air, but you just explained it in 15 minutes. Love your videos!
Great video, very well explained. Fantastic for the generations who didn't grow up with carbs. This will help to keep our muched loved machines used and loved for generations to come.
Best carb video hands down !! Great training piece for us novices to watch and understand carb concepts from a seasoned expert. There’s huge satisfaction in becoming more self reliant / self sufficient. Many thx !!!
As a retired mechanic (who still rides) I think this is an excellent video. I have worked on everything from motorcycles (mostly kawis) to automotive to heavy truck /heavy equipment and that was a great description on carb operation and idle tuning. Happy to subscribe to your channel and look forward to viewing other carb vids. Congrats.
Thanks for the encouragement man! Happy to have you with the channel
Hey man I have a question, does the idle screw also affect low rpm power or do I still need to change the pilot jet? Thanks 👍
I need a mechanic
As a retired industrial engineer and maintenance manager I have worked with hundreds of people over my 45 year career. The key to teaching someone ANYTHING related to mechanics or industrial automation or most any other field, is to not only teach them what to do and how to do it, the most important thing to teach them is the WHY you do it! Teaching them the theory of how anything is supposed to work helps them to understand the WHY! Without the theory behind what they are doing they are just memorizing a few basic steps ie when I see this I do that. You sir are very good at teaching the theory of operation along with the what and the how. Keep it up!!
I appreciate this post. Many people bag on my lengthy rants. I get it, sometimes I repeat myself in three different ways lol . What everyone needs to remember is that I am a technician at heart. For me to fix something I have to know how it works. Just like you said. So my videos organically come from that angle. The why to me, is more valuable. I assume everyone thinks like that. But in actuality I’ve learned that it is what some people care less about on KZhead.
Yes, great point. I wasted years trying to teach people the first thing without explaining why they need to know it. Guess I thought it should be obvious that if you dont know the first thing, you don't sufficiently know anything. And No, this is not a disguised insult. I'm serious. The first thing is potential. The only property of the first, fundamental, and only necessarily eternal principle and absolutely unbrekable Law: Allowance. The idea Yes is fundamental to anything and everything. Only telling you because as an enginner, you may be able to appriciate the lonly real Law.
This was totally helpful. I am troubleshooting a DR650 carb. Based on your video, the carb was running rich. I got the carb dialed in now. Thank You! 🏍️✔️
I’ve been working old bikes for decades and just when I thought I’ve seen everything I guess I haven’t, thanks for the amazing information on this. The main thing I’ve learned about carbs is that to listen to your bike it’s what I tell all my friends. Believe me when you listen to her, it pays off in the end.
This has been the most helpful video I have viewed so far about personal motorcycle maintenance. Thank you
Good info here. I have been using a ColorTune see-through spark plug from Gunson to set the idle mixture....by watching the color of fuel burning in the cylinder. Yellow glow is too rich, white is too lean, good deep blue is the ideal mixture.
Your explanation of the lean and rich conditions of the how the engine operates was fantastic. Never had it explained that way to me and then backing it up with actual examples just really solidified it for me. Thank you so much!
Glad it helped man!
So good - thanks Cody! Just re-set the mixture of the Dellortos on my '75 Moto Guzzi. They were very lean as I had set them prior (per "conventional wisdom"), and I had all the symptoms you described. Now it warms quicker, idles lower, drops from a blip faster, and no flubby delivery from 2K to 4K rpm. Easy and fast to do too. Awesome!
I do not think you talk too much! Enjoy watching you explain things I seem to understand. (great job man) Thanks
Glad you made this, I have a friend who's having some trouble understanding carbs so i sent this his way
First time I ever understood how to actually do this. I also love the fact that you don't care what type or brand of motorcycle the viewer is riding and instead make everyone feel welcome. You have my sub to the channel, now I'm off to find a video of your on how to clean a carb properly, as that's where I'm currently at with my 1988 Yamaha YZ125. Thank you! :)
Thanks for hanging around Robert!
@@TheMotorcycleMDI have a 1974 ST90 Honda and need a recon head and jug can you help me locate these parts .thanks
This has been the most comprehendible carburetor video I've viewed. Thank you for breaking the process down in simple terms, and performing it live. I have much more confidence in tuning now thanks to you sir. I wish you the best.
Glad it was helpful!
I have struggled with this aspect of carb tuning for a long time. No one has ever explained the theory as you did. Simple steps to remember, hanging idle and drop being lean and the drop below idle too rich. Awesome, beautiful explanation very nicely done. My 95 Ducati SS and 74 Honda 360 are very happy. Thanks sir.
Couple of things. Not bad. However, do not blip the throttle. When you blip the throttle, slide goes up feeding fuel, and then drops cutting off air. It results in a rich mixture. The best way to adjust the pilot/low speed circuit is to stabilize the idle/warm engine, set the idle speed, and then start turning the mixture screw either in or out. (It doesn't matter which) if the idle drops, you're going the wrong way. If the idle goes up, reset your idle screw to bring the idle back down and repeat. You want to get to the point where turning the mix screw one way or the other either makes it worse or does nothing at all. That's your sweet spot. Much harder with a multi-cylinder motor. As for your comment about air screws being more sensitive to adjustment, it's likely because, if the carb has an air screw, it's probably either an old street bike or something that the EPA didn't require a fine adjustment. Because of this, the taper is fatter and produces a more pronounced change with the turn. The EPA carbs had a long slim taper. (Really easy to screw them up if you turn them in too hard so be careful) They require a lot more turns to equal what something like a 1/4 turn on a non-EPA carb would take. You also mentioned compression but left out valves. A tight valve, bad seat/valve is going to throw things off so, before adjusting a carb, make sure the valves have been adjusted and the engine run. Lastly, in the 80s Yamaha made dealers purchase Allen exhaust gas analyzers. You'd install fittings in each exhaust and get a reading from a single cylinder. None of my co-workers used it but I got familiar with it. Yamaha specs were out to lunch, but I figured a great way to use it. I received lots of favorable comments from my customers when they got their bikes back. Probably the biggest take away I got from using it was, after the carbs were set on the machine, I'd check turns out from seated. These were the thin taper screws, but they would range anywhere from 1 1/2 to as far out as 3 1/2 turns! (2 1/2 was baseline) It all depended on the seat in the carb and how badly the factory had wound the screws in. (I'd actually find some that were completely seated!)
Thank you Mike. You just fixed my low idle and backfire issue. A diamond Gentleman :)
Do you change the low speed jet if your fuel/air screw is to far in or out?
@@elmeradams8781 you can.
Where is yur shop?
Keep on talking, that's the best way we can learn anything. Great timing, I am just doing a single cylinder carb clean on my bike and this was the second video of yours I have got notice on. I'll be researching your videos to check what you have there...Thanks from an older biker who forgets too much. All the best from Australia.
Love your attitude and willingness to help us out with taking care of our motorcycles.
Hi Cody Greetings from NZ, I have slowly learned how to rebuild and sync my carburetors but haven't yet mastered the fuel mixture adjustments. Thank you for sharing your knowledge with me, I appreciate what you do.
My pleasure man!
I’ve watched your other videos that include mixture adjustments, glad to see you bring it back to light. In the past I never knew how it was supposed to be done. Thank you for sharing!
watched your short about the air screw vs fuel screw and this just sealed the deal im dialing in the 73 at3 this weekend for sure! thanks for making things simple for a simple guy!
I have been battling my 90 dr350 carb for weeks now and have been searching for a helpful guide. Nothing has worked. Then, first thing this morning, you post this. This video has been very informative once again. Thanks cody!!
Check valve clearances
I always did the highest rpm at idle and it has usually worked for me. Warm it up, then set a reasonable rpm for idle then fiddle slightly with the needle until you get the highest rpm possible.
Or highest manifold vacuum
Very well explained procedure, then emphasized with a well presented actual example of the procedure. I'll have to begin watching more of your videos. Very impressed! I am getting ready to begin some restorations on several bikes I've collected thru the years. This type of information will probably be really useful. Thanks so much for presenting your videos!
Really good much-needed tutorial video. Thanks Cody. 🤠Greets from Australia (200,000 miles circa 1962 - 1976, then 2-3 yrs about 16 years later on)
Wow am 62 years old and I did my carburetor on my ATC three wheeler thanks I followed your video how to clean and how to adjust it and I did it yes 👍 thank you so much 👍👍👍
You definitely do not talk too much, I would literally pay for this information I mean you explain it so well, better than most people. Thanks a lot brother!
All of your info is accurate, if i ever had to go past 2.5 turns out on the fuel screw though id always go to a larger pilot then start over to prevent the chance of the screw vibrating out over time. I personally dont feel like its got enough spring tension to hold the fuel screw in long term past 2.5 turns out.
Shit. Mine are way out
Your carb tuning tips are priceless! Thanks! Now if I can just remember all of them. A Mikuni HSR specific tutorial with explanation of all of the circuits would be awesome, too.
Bro you've just helped me with my new bike and the new carburetor I put on it. I had absolutely no knowledge of how to tune it and your videos saved me. THANK YOU I am so happy to hear my first bike run like a champ and I'm learning so much about bikes I'm glad I bought this cheap beginner bike to learn with.
Perfect! 👌 Very well said, very clear and with practical example, brilliant.
First off, i love the fact you “talk to much” i have learnt more from you, than for ANYONE on youtube (proud to call myself an MD member) This vid explained so so so much!! Keep them coming 😊 they are AWESOME!
Super encouraging to hear this man thank you
Thank you so much for the video. I'm a woman who works on her own motorcycle and I'm never awesome at tuning the carb so this helped a lot. I just put a whole new exhaust system on so I need my I might have to alter some things with the carb
You are the man. Best carb advice ever! Talk all you want. Your videos are the best
Your video could not have come at a better time. Tuning my rebuilt carb on my CM400E today. Thank you so much!!
I got a cm400t and I'm about to do the same. You mean carbS right? Lol.
You are looking for the highest idle with the mixture screw, which allows the slide to be adjusted to the most closed position which will reduce run on etc. The highest idle is the most efficient air fuel mix poss, hence why it idles the highest with the correct mix. If the screw ends up in to far or out to far to gain that highest idle then it is a guide to know which way to change the pilot jet to suit.
Bro Thank you this video is one of the only videos that actually gives detailed info on how to tune your carb and what to look for the correct way right on Brother! Blessings🥂💫
I use this method all the time back in the day when I started on motor with a carburetor works very well by listening at feeling the Motors 45 years easy
I've been working on carbonated engines (controlled fuel leak) for 60 years. I was predicting every move you made. Great video.

Of course! Glad it helped
Thank you so much, probably the best carb tuning video I've watched so far! really appreciate you sharing your knowledge and experience with us
Thank you. This really helped a lot. I work on a lot of small cheap carburetors that don't necessarily do what you think they would. With this information it made it a lot easier to figure out what was happening since most come without any idea of what they are and if air or fuel screw. Again thank you for making it a little easier.
ppl really complain about u talking to much. these are how to vids, i hate how to vids where u don't get enough information. ppl just like to complain
I just set the idle speed screw a bit fast, keep adjusting the idle mixture until the engine is at its fastest then richen the idle mixture by 1/4 turn and readjust the idle speed back to normal. However, on my 2stroke bike, I set it lean and leave it there. Not bothered by a hanging idle and it prevents the engine being fluffy from oiling up a bit when running slowly in woods.
Thank you for this great knowledge! I’ve got a dual carb which I was terrified to mess around with but your videos give me confidence to work on my bike!
Wow, I have learned a lot from this video. Doing a carb cleaning right now and wanted to make adjustments to the air/fuel mixture screw and now I know what to hear for. Thank you!
This is the best carb tuning video i have been able to find. Great explanation and real-time example
Would be interesting (for those of us who like to nerd out) for you to take a wideband o2 sensor and see where the mixture sweet spot ends up being on a gauge after you tune by ear as shown here. I’m guessing this method would produce mixtures around 12.5-13.0:1 air fuel ratio for pump gas.
For maximum performance, 13:1 is common on street engines. It may get richer a when accelerating as rpm is still building.
@@greatestevar Depends if your air or water cooled and if your using an over rich mixture to compensate for bad combustion chamber design (extra fuel to prevent knock)
Nice video and good explanations. Although as a generale rule you can tell what you are adjusting (air/fuel) depending on the position of the screw, there are exceptions. For example my Honda 50cc Joker which has an air adjusting screw but positioned on the 'fuel' side of the carburetor. What is worth mentioning is that a 100% way to determine what kind of adjusment you have is the type of screw tip you have. If you have a conic shaped end of the screw it is an air adjustment screw. If it ends with a very thin needle shape then it is fuel that your are adjusting.
Thank very much, you are the first who spoke logic into this situation. No you not talk to much, you explain things. Thank you very much.
okay I just had a little 22 scooter and I have watched so many videos I changed out my carburetor went with a bigger car never done any of this before in my life and I just watched KZhead figured out how to do it but I watched so many videos and none of them exactly tell you how to do the the air fuel mixture your video I followed exactly and it's cranked up every time it idles perfect and it runs great thank you so much for your videos that you do.
Hey Cody, thanks for your video and tips. Though you picked an easy one by working on a bike that only has one carburator. This technique is pretty hard to apply when working on a 4 or 6 cylinders engine. After years of trying this I finally came to the conclusion that the only (easy) way to fine tune the idle mixture screws is to use a colortune where you can see the color of the mixture when exploding in the cylinder.
Totally concur. Using a simple single carb while making it easy to see, hear and understand, simply does not apply well to multi carb setups. Whether that is 3,4 or 6 carbs.
Yep. Adjusting multi cylinder pilot (fuel) screws all at once and then judging results by how engine returns to idle is wrong. Carbs must be synced first and then each one adjusted one at a time while correcting carb sync and idle speed as you go along. Honda's method is called an "idle drop" using an accurate tach to determine proper adjustment but having a good ear is very helpful. Ex Honda Ser. mgr. @@anonimous2451
What is a "color tune" a movable O2 sensor or are you just referring to the plug porcelain tone after a short run with new plugs, or something else?
@@jeffreystroman2811 It's a Tool. Google it. u will see
Hi love your channel, have you ever tried welding wideband bungs and testing carbs AFR? I have AEM x sensor and two welded bungs to tune the carbs in all RPMS and i have found that my old Suzuki is way more sensitive for lean mix than rich. When you are leaner than 13 idle drops clearly, above 13,5 it start to pop. Between 13 and 12.5 rpms rise but not by much and to hear a significant drop in rpms you have to flood it bellow 11.
you've got it man. You need something to accurately measure the mixture. Back in the 70's we had CO meters which measured carbon monoxide % , most manufacturers published the designed %. If you check out old dyno vids you'll see thermocouples in each header to measure gas temp. Then came 3 then 4 gas infrared exhaust analysers (CO, hydrocarbons, O2, CO2). Now most seem to rely on only O2. It seems to get good results. cheers.
I’ve truly enjoyed and appreciate your videos. Thank you for all your help working on my carbs. I’m not sure who or why someone says you talk too much. Details are needed when explaining how to instructions.

excellent video, i love it, ive just turned 18 and i have my dad's 26 yr old hero-honda splendor and i've been adjusting that screw without knowing anything, i used it to get different power and economy and also changed to a leaner mixture in winters without knowing, never touched the fuel screw, now imma fiddle with it
Thanks i put new exhaust on and had lean issues good to see someone explain attention to detail well explained

Oh my goodness. Thank you. I have been have an issue with my 79 kz750 twin. Turns out I have the air mixture screw. Cant wait to get this dialed in!
I lost hours watching videos on this topic.. you just made it 100% clear in 10min.. subed and thank you soo much.. I will try this cuz I have very strange idle problems on my bike... it sometimes idles.. but most of the time if I let it idle for 30s, it dies the moment you twist the throttle(I can save it if I give it more than 50% throttle)... it restarts no problem and works like nothing happened.. but when idling for less than 5-10seconds it has great response, only when it sits idling for longer time it wants to die
As usual Cody - ypur Video are super helpful and make is so much easier to understand the dark art of carbies. Sharing your chanel with all my mates and others in my local Facebook groups. Keep up the great work and I am sure you will hit 100 K on no time.
mate you are the carby master you have enlighted me about the air mixtures and how to spot them just blip the throttle and listen best advice cheers
I used to use a color tuner worked awesome for sensitive carbs, especially multiple carb setups
thanks for the excellent video. showing us the lean and rich conditions help.
Thanks for this lesson. Just put a new carb on my bike. This will help me get it perfect.

Bro thank you!!! Other say you talk a lot but boy it helps tremendously for us folks that are just learning how to tune bikes. I have a mini bike carburetor issues. Trailmaster storm 200 Upgraded my air intake and jet then the carburetor started to leak but it’s the stock carburetor and after watching your video I’m feeling better and more confident on what to look and listen for!! Appreciate you!! ✊🏽
Exactly the information I currently need. I love learning new things. Thank you.
You sir are brilliant. I actually understand the process now to DIAL IT IN!!! Thank you very much.
Subscribed and liked. Seriously, been wrenching on bikes and cars since the 60s and have not heard this explanation of the idle screw position in relation to the main jet. If I have it correctly; if the idle screw is pre main jet, then that is the AIR adjust and if the idle screw is aft the main jet, that is FUEL adjust. Got it. Great info.!! Wonderful, and thanks man! rocket
Great info. I have my Armstrong MT500 to set up tomorrow. It's taking a while to settle back to tick-over, so now I know it's lean. I know what I'm doing now. Thank you.
Great, Clear and concise instruction - just about the best i've heard from anybody, Thank You!
That means a lot thank you!
On 4 stroke singles ive always used bike digital motorcycle hand tach then would lean the mixture out until it starts to stumble then richen it to the highest rpm before stumble then set idle and run thru the process one more time but at the end when ive got the richness set I'll turk it 1/16 of a turne more. It eliminates backfire on decel and takes away any hesitation from idle circuit transition to needle circuit. On multi carb ive always used a multi port mercury guage and calibrated carbs with that.
