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?.

[@user-vr8wr3xt1s]

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!

[@desmo8755]

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.

[@draizwrm]

​@@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

[@desmo8755]

@@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.

[@draizwrm]

@@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.

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!!

[@TheMotorcycleMD]

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 KZbin.

[@GBCobber]

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.

[@hoody0778]

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...

[@mikestackhousemusic]

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!)

[@TornadoCAN99]

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.

[@claytonbenes7774]

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.

[@wadenvern]

[@jonnoMoto]

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.

[@salvatoregiovanni8967]

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.

[@1crazypj]

For maximum performance, 13:1 is common on street engines. It may get richer a when accelerating as rpm is still building.

[@tudorXcorbul]

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.

[@sky-im6zg]

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.

[@ihateemael]

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.

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.

[@anonimous2451]

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.

[@grebermuncie3904]

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

Good stuff bro I bet you're a kick ass mechanic. This was very helpful. I just installed a card on my bike and have to initially said the carb. There are not a lot of professionals like yourself making videos, most are by average dudes so it's refreshing to have a professional giving advice. Keep up the good work and once again thank you.

[@akshatgangwar7759]

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

[@henrysmith8012]

Been doing this my whole life. Very good explanation.

[@StandonBiznessofficial]

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🥂💫

[@soulriderman]

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.

[@formegolf]

Hey, great videos, I just wanted to tell you that this technique has helped me with my project and now I will be using this method for all my build. Thank you so much for making this video and sharing your knowledge. Have a great day! Mark

[@richwiebe8084]

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.

[@MapleCorsair]

I watched your video at 2AM last night before going to bed and now my 2 stroke went from bogging to running smooth as a swiss watch. Thank you very much for the informative video, helped me out a bunch!!

[@TheMotorcycleMD]

Fantastic!

[@donaivanbacorro3916]

Really helpful. I really dont have any idea how my uncle fine tunes my motorcycles. Now i know what i am looking for. ❤

[@bradley7723]

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. Your video is great for those who may not have the tooling or like I've had to do in the mountains field set your carb for elevation changes. Great video.👍👌

[@jeromewilliams2678]

Bro i change six plugs in 2 months and watch sooo many carb videos and your vid helped me mine is an fuel screw thow.....thanks👍🇯🇲

[@KrogPog]

I just bought a bike and I've been really struggling turning the carb after I cleaned it this video was very helpful thank you so much

[@tayloroneill2332]

Thanks i put new exhaust on and had lean issues good to see someone explain attention to detail well explained

[@robertedge6902]

Thanks for this lesson. Just put a new carb on my bike. This will help me get it perfect.

[@jeremyfasulo2974]

You sir are brilliant. I actually understand the process now to DIAL IT IN!!! Thank you very much.

[@JiggaDubbz4K]

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!! ✊🏽

[@carlosgomes6074]

Thank you for your great explanation, going to apply this technique to my car with carberator. I have the exact same problem you described. .

[@booboo9886]

Think for the end definition explanation on turning a carb iv been doing it for 17 to 20 years with my grandpa and professionally 6 years on small engine by ear and the way you brake it down makes sense now Think you man

[@stefaandeconinck1531]

Thank you so mutch. I’m 50y/o and I have a CJ 750 boxer engine. I gonna try this for sure.

[@DaveLowe28]

Such a simple yet effective method. Alongside your jetting for pod filters video, I'm finally on the right track to getting my bike running right. I was so far off but this technique let's me know that quickly and easily.

[@TheMotorcycleMD]

🤙🏻🤙🏻

[@dave-d]

Awesome! Just took on a 27 year old Yamaha TDM850 twin and having to re-hone my mechanics skills! Ain't seen a carb in years. Thanks Sensei.

[@fredsmith4106]

If you have problems with trying to get a stable idle on the TDM - I/E idles too high and dies if you try to drop it down, there is a very common problem. Over time, the slide needles will ‘peen’ the inside of the emulsion tubes, making the hole oval in section. Replacing the emulsion tubes is pretty simple and cheap. It was a very common problem with the TRX/TDM series.

[@jessegalea5524]

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

[@iblokeversion1]

Exactly the information I currently need. I love learning new things. Thank you.

[@ericbatty4441]

excelent tip, my dad taught me this as a 15 year old, great video

[@kellysmallwood6205]

Love it When you explain yourself that’s how I rebuilt my carburetors

[@timmichael3554]

Thank you for taking the time to make these videos to help others. Well done!

[@Big88Country]

New Sub, thanks my man!! Trying to buy me an old Harley Evo with a carb. I had a 05 Electra Glide twin cam that was carburetored and it took me awhile to find the best jets and mixture for it. When I first got it I could tell it was running really rich. I was barely getting 150 miles to a tank of fuel. When I finished I was hitting 200 per tank and it was running better than ever. Love these bikes with carburetors! The sound alone is much better than the fuel injected bikes. I'll be checking out all your videos!

[@elkabong8460]

Talk all you want. I appreciate your sharing. It works for me.
