Man, I went to school for motorcycle/atv repair, and have worked in shops for several years, and nobody has ever explained carbs as well as you just did! All I can say is wow, and thank you.!
Great video! At a point where I love working on everything myself , and this helped me so much about tuning a carburetor. So anytime you need to adjust pilot or main, you put different size jet in entirely? Needle jet you can adjust w the different rings on needle....
You was right the flow height need to be adjusted but I don't have nobody to do it ain't no good mechanic down here where I'm at they don't know nothing
I've been a mechanic for 7 years, I work on old cars, chainsaws, motorbikes, and have messed up more carburettors than I'd care to admit, to get to the point I'm at now. When I did my apprenticeship the training organisation only spent a 3 hour lesson on carburettor function, and we never worked on one. This video should be standard viewing for any mechanical course. It explains everything perfectly, and I'll be sharing it with anyone who cares to listen. Well done, and thank you!
@@RollingWrench Super informative content! I live in Albuquerque, which is the same elevation as Denver. And I am having an issue with my idol circuit. It is a 21 mm OKO Carb and I am running a 30 pilot jet and I'm still having trouble with the motor not wanting to stay running at idle. It came stuck with the 40 and I've been working my way down. Seems to idol a little better with the 30 but still not there yet. My question is, do you think it would be OK to go down to a 28 pilot jet. That is the smallest one that I can find for this carburetor. Mid range and wide open throttle are great. Thanks my friend👍
I got to this video because I built my own jetski, it idols perfectly but when I throttle nothing happens. So now I'm hear hoping that a carb tube up is all i need
2 years later and this video is still saving marriages! I was so pissed off trying to get my carb tuned and the enrire time i was trying to fix my idle by screwing up everything else. Thank you so much for putting this out there!
I like how you put marriages in there because it most definitely makes for an angry husband when he can't figure out how to adjust his damn carburetor! Haha! That was me a few days ago, now it's time to put this video to the test and adjust that carb!
Makes an angry wife also. All that time wasted trying to tune the carb, you coulda been working on that thing you've been promising to fix for several months @James-c8m8x
I've been tuning carbs for years on everything from 2 stroke to brig's to VWs to racing V8s and many multi carb set ups from street strip racing and off road rigs. You have definitely explained in 30 minutes what I spent many years early on to learn trial and error as a young man. I'm the go to guy for my buddies when it comes to tuning carbs and timing and over all engine flow from air in to the exhaust out the end of the tail pipe. From now on I'm sending the guys that come to me to your video so just maybe they can learn for themselves. Teaching guys about tuning carbs is like talking French to a Spanish taught cajon You got it covered down to plain English.
Having been a teacher part of my life and an engine DIY-er I think this video is one of the best I have ever seen. It is extremely well planned, documented and explained part by part. Hoping you will appreciate positive comment to make it even more perfect, you could spend a bit more time on pilot jetting versus the turning of its mixture screw (with the wideband in place). As an addition you could also mention some carbs have a separate idle air-jet on the filter side of the carb. Thanks a lot for taking the time to make the video.
Very informative and helpful, I have watched this video several times and it's helped me tune my Grom clone with a 212cc big bore race engine and Nibbi PWK 30mm carb. Your tip saying to make sure the "throttle cable has some slack and free play" saved me because my throttle cable was too tight and pilot jet was too small. Thanks for sharing your knowledge and keep up the good work!
A lot of work went into this and I hope everyone learns something and appreciates the trouble this guy went through. I'm 73, been flying two cycle ultralight aircraft since 1978 (call it 44 years) & recently Paramotors. Even I learned quite a bit from this. Many thanks to Mr. Rolling Wrench!
If a person can't tune a basic carburetor after watching and reviewing this they really don't have aptitude for this and shouldn't be messing with it. Truly a comprehensive video and very well explained. You are absolutely an asset to the engine community! I have tried a few videos and I don't get more than 500 to 600 views and very few subscribers. You are absolutely doing it right with video making as well as all the valuable education you dispense. Very much appreciated. I have your wheel set, while gy6 swap kit, the fat tire kit, carburetor and engine brain. Absolutely quality parts.
This by far and above the best carburetor, tuning informative RUclips video in existence. This mans knowledge & expertise makes all of these other RUclips video’s on carbs look elementary. Great job man. Definitely earned a sub.
I don't normally comment on videos but here we go. I'm 16 and do a lot of mechanics. I am self taught. Recently I got 2 of these carbs brand new for a snowmobile I'm working on, and I had NO CLUE what I was supposed to do. Non of the videos I could find were thorough and I couldn't find a good manual. AND THEN I FOUND YOUR VIDEO!!! Sir this is completely amazing. The way you took the carb apart and explained every single piece, and then actually showed yourself tuning it! I am so grateful for you. You earned my like and sub, and I wish I could give this video a thousand thumbs up. Thank you so much!
FINALLY!!! I got to understand carbs. This video is the BEST on the subject. Your "methodical" way of approaching the subject from start to end is exactly what we need to start knowing carbs. Thank you for this wonderful, educational video.
I am a snowmobile/ATV/PWC mechanic of many years. This video was exceptionally well done. Something to add.. You start with the pilot circuit because that jet is there from beginning to end. It continues to spray along with the other circuits. You need to get that one right first. He does exactly that, I am just pointing out why. Excellent video, well done sir!!
Thanks for this... i was wondering how that worked. It makes sense that all the jets just add to eachother because it will need more and more fuel when you open the throttle (air) more.
I've been shade tree adjusting carbs as needed for years, sometimes great sometime horribly. That just explained everything. Best tutorial on this subject ever. Thank you very much!
@@RollingWrench got a bog with rapid throttle snap otherwise runs perfect PZ30 pumper carb. On cg250 air Any thoughts? Cam bored and coolers + exhaust are done.
This is an excellent video. Months ago, I wrote of sharing value of your experience--instead of making info-tainment, this is the kind of thing I meant. I've worked on all kinds of mechanical contrivances, but back when I had my old motorcycles, they didn't have a power jet, so I learned something too. Thank you.
This is hands down the best carb tuning video I have ever watched. So much information presented in a way that is extremely easy to understand for anybody at any skill level. I’ve been working on small engines (ATVs, snowmobiles, dirt bikes, etc.) for the better part of 9 years and learned a lot of what I know through trial and error. Never have I ever seen somebody explain carb tuning so well and make it as simple as you have. Amazing video! I learned a couple things I wish had learned when I first started.
I can just tell by the length of the video and your intro that it's worth watching. I've messed with carbs on 2 strokes mostly and even have my banshee with 2 synced carbs working perfectly but really appreciate these videos. It's free continued education
I loved this video!!! It makes it so easy to understand and when you have that one customer that has got it all backwards ,this video can stop all the what if questions before they get started... Point Blank Period!!
Great video. Watched it at breakfast, bike carb out, cleaned, jetted and running better than ever by lunch. First carb service ever. Thank you. So happy.👍👍
Excellent video...My 2 stroke dirt bike was bogging down off the starting line, now I know why. Thanks to this video I now know what the problem is and how to fix it. Thank you !!!
by far the best explanation on how carbs work and how you tune them all in one video you did a fantastic job at explaining how and why a specific change effects the rpm and mixture
That was one very informative, easy to follow explanation of carbs! Thanks for taking the time to create such a great video, it is truly brilliant! Cheers!
Wow man that is the best tutorial and explanation I've ever seen! I knew a couple of the basics but you just brought everything to light and hit a home run! Thanks for the information.
YOO thank you my guy 🙏 just rebuilt the carb on my 1990 Suzuki DR250S but I was having some trouble tuning it, found this video and got the idle and fuel screw "set". But during the test ride i was stumbling at around 5k rpm when I full throttled it, and acceleration was poor overall. So I came back and watched more of the video and your test rides, and thats when it clicked. I checked and sure enough, my old main jet was bigger then the one I got in the rebuild kit. Since the main jet didn't necessarily need replacing, and i learned about the float bowl drain giving access to it, i was able to quickly rotate it, swap the jets, put it all back and just like that the bike is running good again. Long story short, while its been running and rideable, ive been troubleshooting, working on, and riding around many issues during this restoration project for the past 3 weeks, and just to top it off its my first bike lol so thanks again for helping me with this crucial step in the project! Next up are some proper enduro tires (currently has motoX) then a Trail Tech head unit and turn signals. Best of luck everyone, and ride safe 🤘
The absolute best lesson I have ever witnessed on the topic of carburetors! Introducing all the "players" at the beginning so as to establish a vocabulary was a classic instructional technique. Taking the time to explain not only the purpose of each part but how their functions were related was superb! The cause and effect scenarios for rich and lean and how to remedy the situation for a near perfect stoichiometric ratio were exemplary! You have a gift for taking what can be a very complex topic and making it easy to understand so that others can put the information to use with successful results!!!
Well done in order and layout, this is a process that needs attention to details, and you have identified every component to follow and understand functionality my 10 year old can tune a carb thanks to your demo . .
Well prepared, I've been trying to teach my son about how carbs work. You just saved me hours! This explains it better than I can. Also, I always thought back firing on decel was rich but logically, it's when enough fuel gathers to pop. Makes sense. Really appreciate your effort.
Subbed!!! I'm a Motorcycle instructor in Ohio and our carbed bikes are Teedubs, a ton of old Rebels, and a few Suzuki GZ's. My personal bikes have been carbed and I'm definitely no expert, but I have limped my way through adjusting them so they run. Your video clarified and integrated lots of the information I had cobbled together in my head. Excellent!
I stumbled onto your video, almost gave up on looking further just before I did. What amazes me is after watching your video twice, I have no questions and im not pulling my hair out. Some people like to hear themselves talk and provide little to nothing important, they should watch, listen and learn from you..i know i did. Thank you for taking the time on making your very informative, quality video. I am now a loyal subscriber. Gotta love it!
Mate I've been working on cars and bikes my whole life and have a lot of experience with carbies and I have to say your video is one of the most informative and very well thought out/planned videos on carbs I've ever seen! Good on ya! Cheers from down under! 🇦🇺
I found this really informative and as a keen motorcycle enthusiast with hardly any knowledge on how to maintain bikes I firmly believe that I could do what your video shows. I may need to watch it a couple of times more but I definitely will be having a go. Thanks for the lesson.
Thank you so much, got a old 2003 Yamaha ttr90 that sat for 10 years in a garage, got a new carb and kept rev bombing as soon as I started it, thanks to you it runs beautifully
Excellent tutorial, thanks for the work you put in to this. I rode modern sport bikes up until a few years ago, all with EFI, but recently got back in to riding with a single cylinder carbureted dual-sport. This will help me tune the carb and get the best performance possible out of this little thumper.
For dummies like me out of all the YT videos I’ve seen on how to tune a carb your explanation was the MOST thorough and understandable! I have a 2 stroke Daelim Cordi and just slapped on a power jet carb to see how it works. I had problems with what jets to use but after watching your video it runs like a champ 54mph I almost gave up on this carb but thanks to you I didn’t waste my money. Thank you very much keep up the good work 👍👍
Duuuude! You showed up exactly when I needed you. Have a PWK that I'm working on and couldn't find a decent video for that type of carb. Thank you!!! 👍
Thank you for all the time amd effort you put in to make this video. I thought I already knew how carbs worked and how to set them up and tune them. This video let me understand how my turning of screws actually altered how the carb functioned. I came across this video as the top You Tube recommendation after watching a video by Dustin of the "Smarter Every Day" channel. He had built a working see through Carburettor and uses a high speed camera To show how the carb uses the venturi principle to mix the fuel and air for to the engine to use. All though he had the choke and throttle on his see through Carburettor his video only showed the principles and not a real life carb. But by watching his video and then yours it gives a perfect understanding of the carbs working principles and then yours shows how those principles translate onto a proper engines Carburettor, what all the screws control and how to use them to tune the carb to its full potential. Both videos I think were brilliantly made, easy to watch, well thought out and turned a fiddly job into something much easier to do. Thank you for all the time and thought you put into creating a perfect mix of a good quality video and great subject and educational content. Keep up the amazing work, you just got a like, subscription and a notification bell ring. I'm now going to look at the videos you have made previously and probably binge out on them for a good while. Thanks again.
This video made me realize that the float has a needle, when I took it apart it bounced under the tire of the mower and I had no idea to look for it until watching this. Now it's running again and I can feel like a proper home owner lol
You nailed it, all in one technical explanation as connected to the actual site condition. Double Thumb's Up. This guy , he knows what he is talking about with solid output and really skilled unlike others that are pretenders .
Dude 2 years later and still relevant i was scared to change my carb on my 2023 ruckus due to the jetting, have a performance exhaust, air filter delete, and pressure tube and all i needed was the performance carb now im going to change it and see how it goes thank you!!!!
Thank you Rolling Wrench, i've seen videos about carburetor tuning and this is the most informative and helped me understand more easily. The demo shows that this was not based on books only. Appreciate this!
A friend shared this on Facebook. Well done 👍! I'm 58 and have been messing with engines probably from around 7-10 years old. I've blindly "adjusted" carbs, and kinda gotten things to run okay. New Sub.
I've watched a lot of tutorials about tuning carb, and by far this was the best among the rest. Best explanation ever made. Now I can do a lot better in working carburetor.
This was the best explanation about jetting. And I'm not mechanic. Got some knowledge all-around from my father's. And this is valuable for me because I'm setting up my 08 KLR. Got a Big Gun exhaust and k&n filter. Getting decel pops and idle mixture screw won't give me more flow. Running 2 turns , don't hear any increments. When I reach 3 1/2 turns, the bike shutdown. Let's do it 👍
Your instructions are truly amazing it makes a lots of sense because the needle controls every thing to make the engine gets a perfect performance, let me try that thing adjustments because the performance of my machine is so groogy, looks like spitting out so much gas, you're the best teacher on live performance
I am so happy you broke this down. I bought a Yamaha Virago 750 two years ago and did some cleanup including rebuilding the carbs and I know it can run better. Now I know just what to do. Thank you!
The front cylinder exhaust is almost non existing at idle but normal at cruising. Then when I get up to 65mph I am losing a cylinder which comes back when I slow slightly. This is a result of bad tuning, correct?
That was so informative. If someone is really interested on being a motocycle, ATV, UTV technician, this is not to long video. I'm thinking about getting that kit.
To be honest, for a beginner this is something to always come back and reference from. The skill will set in over time but this is really informative. I also learnt to be careful with gas on that "o" ring when you opening your carb. I also learnt that backfiring is not "rich" but "lean"... lol that really helps to know.
I learned that popping on decel is always a lean condition, thank you! I have a KLX250sf and it’s been popping since I bought it 10k mi ago (and with 10k on it) and I’m worried that I’m doing damage by running lean for so long and riding the piss out of it cuz it’s a 250. It has a fmf power bomb Q4. I’ve been thinking it never got jetted when the previous owner installed the pipe. This video is badass and you’ve got a new sub for life!
this is hands down THE best video on a carburetor on youtube! I'm buying a new motorcycle but it will be my first carburetor bike. This video is gold and will be in my favorites :D
Gotta say I really appreciate the level of detail. I just cleaned my 4 carbs and took the opportunity to re-jet my 2007 Yamaha RSV because I added Monster Ovals and K&N air filters last year. Since then, the bike only ran at 1/4 choke (Mikuni plungers). When I tore them down, all the jets were clear, but the float needle gaskets seats' seals were hardened and started leaking which is why I did the job. Went up from 15 to 20 on the pilot jets and from 115 to 122.5 on main jets in the front banks and from 123 to 125 on rear banks. (Something like that. Can't remember the exact original size on the rears. I still have all the original parts though). Set pilot screw at 3 1/4 turns. Got it put back together, and she started right up with little initiall choke and ran strong at cruise speed or WOT but was getting afterfire and a little flame on the left pipe during deceleration, which I didn't mind much. Actually liked it, but didn't want it ruining anything or fouling the plugs. Fast forward to 2 days later and it wouldn't run long on cold start. Choke didn't help but actually wouldn't run at all nor start with choke. So now after watching this video, I'm thinking I may have to lean out the idle circuit as I have a sightings better understanding

So I came back and watched more of the video and your test rides, and thats when it clicked. I checked and sure enough, my old main jet was bigger then the one I got in the rebuild kit. Since the main jet didn't necessarily need replacing, and i learned about the float bowl drain giving access to it, i was able to quickly rotate it, swap the jets, put it all back and just like that the bike is running good again. Long story short, while its been running and rideable, ive been troubleshooting, working on, and riding around many issues during this restoration project for the past 3 weeks, and just to top it off its my first bike lol so thanks again for helping me with this crucial step in the project! Next up are some proper enduro tires (currently has motoX) then a Trail Tech head unit and turn signals. Best of luck everyone, and ride safe 🤘
Thanks! Most clean and clear carb break down ever!
Thank you 🙏🏻 I really appreciate the kind words and super chat :-)
The absolute best lesson I have ever witnessed on the topic of carburetors! Introducing all the "players" at the beginning so as to establish a vocabulary was a classic instructional technique. Taking the time to explain not only the purpose of each part but how their functions were related was superb! The cause and effect scenarios for rich and lean and how to remedy the situation for a near perfect stoichiometric ratio were exemplary! You have a gift for taking what can be a very complex topic and making it easy to understand so that others can put the information to use with successful results!!!
I appreciate all the kind words 🙏🏻💯. It’s comments like this that keep me feeling significant in this world.
Well done in order and layout, this is a process that needs attention to details, and you have identified every component to follow and understand functionality my 10 year old can tune a carb thanks to your demo . .
Well prepared, I've been trying to teach my son about how carbs work. You just saved me hours! This explains it better than I can. Also, I always thought back firing on decel was rich but logically, it's when enough fuel gathers to pop. Makes sense. Really appreciate your effort.
Subbed!!!
I'm a Motorcycle instructor in Ohio and our carbed bikes are Teedubs, a ton of old Rebels, and a few Suzuki GZ's.
My personal bikes have been carbed and I'm definitely no expert, but I have limped my way through adjusting them so they run.
Your video clarified and integrated lots of the information I had cobbled together in my head. Excellent!
I stumbled onto your video, almost gave up on looking further just before I did. What amazes me is after watching your video twice, I have no questions and im not pulling my hair out. Some people like to hear themselves talk and provide little to nothing important, they should watch, listen and learn from you..i know i did. Thank you for taking the time on making your very informative, quality video. I am now a loyal subscriber. Gotta love it!
Mate I've been working on cars and bikes my whole life and have a lot of experience with carbies and I have to say your video is one of the most informative and very well thought out/planned videos on carbs I've ever seen!
Good on ya! Cheers from down under! 🇦🇺
I found this really informative and as a keen motorcycle enthusiast with hardly any knowledge on how to maintain bikes I firmly believe that I could do what your video shows. I may need to watch it a couple of times more but I definitely will be having a go. Thanks for the lesson.
Very informative and educational! I had a basic understanding, but you took it to the next level! Thanks, Don
Thank you so much, got a old 2003 Yamaha ttr90 that sat for 10 years in a garage, got a new carb and kept rev bombing as soon as I started it, thanks to you it runs beautifully
Made me realize how much I didn't know and taught me those things at the same time. Bravo!!
This is excellent! Thank you taking the time to explain this so thoroughly.
Excellent tutorial, thanks for the work you put in to this. I rode modern sport bikes up until a few years ago, all with EFI, but recently got back in to riding with a single cylinder carbureted dual-sport. This will help me tune the carb and get the best performance possible out of this little thumper.
This video helped me understand so much more about carbs that I hit the Like button 3 times!

Where were this video when I was suffering tuning my carb? 😥
Glad I found this video! Thank you very much! ❤️
For dummies like me out of all the YT videos I’ve seen on how to tune a carb your explanation was the MOST thorough and understandable! I have a 2 stroke Daelim Cordi and just slapped on a power jet carb to see how it works. I had problems with what jets to use but after watching your video it runs like a champ 54mph I almost gave up on this carb but thanks to you I didn’t waste my money. Thank you very much keep up the good work 👍👍
Dude! I really appreciate you taking the time to write this. It means a lot
Duuuude! You showed up exactly when I needed you. Have a PWK that I'm working on and couldn't find a decent video for that type of carb. Thank you!!! 👍
This video was a life saver getting my dual carbs setup. Thanks for such an informative video!
Thank you for all the time amd effort you put in to make this video.
I thought I already knew how carbs worked and how to set them up and tune them. This video let me understand how my turning of screws actually altered how the carb functioned.
I came across this video as the top You Tube recommendation after watching a video by Dustin of the "Smarter Every Day" channel.
He had built a working see through Carburettor and uses a high speed camera To show how the carb uses the venturi principle to mix the fuel and air for to the engine to use.
All though he had the choke and throttle on his see through Carburettor his video only showed the principles and not a real life carb.
But by watching his video and then yours it gives a perfect understanding of the carbs working principles and then yours shows how those principles translate onto a proper engines Carburettor, what all the screws control and how to use them to tune the carb to its full potential.
Both videos I think were brilliantly made, easy to watch, well thought out and turned a fiddly job into something much easier to do.
Thank you for all the time and thought you put into creating a perfect mix of a good quality video and great subject and educational content.
Keep up the amazing work, you just got a like, subscription and a notification bell ring. I'm now going to look at the videos you have made previously and probably binge out on them for a good while. Thanks again.
Was having trouble jetting my bike. Got it sorted because of your excellent video. Thank you for what you do.
Nice dude! I appreciate the support 🙏🏻🙏🏻💯💯💯
53 and started pitbiking.... (midlife...), due to you I understand the carb. thx, !
Niiice!
This video made me realize that the float has a needle, when I took it apart it bounced under the tire of the mower and I had no idea to look for it until watching this. Now it's running again and I can feel like a proper home owner lol
Most helpful video I’ve ever watched can’t thank u enough
Sweet! Thanks for watching:-)
Yes, same! So helpful
I don’t even own a ruckus but this seemed liked really useful info.
I appreciate you dude
You nailed it, all in one technical explanation as connected to the actual site condition.
Double Thumb's Up.
This guy , he knows what he is talking about with solid output and really skilled unlike others that are pretenders .
Fantastic job explaining this whole process. Extremely thorough while being easy to understand !
muito bom meu amigo, meus parabéns pela aula e obrigado por compartilhar o seu conhecimento!
thanks for the video i thought the whole carb worked together when running also how would you do this on motorcycles with 2+ cylinders
Dude, I think I just got my masters on carbs.
Lol yesss!
Next up will be learning Nitrous Oxide haha. I bought a book on it years ago, after reading it I didn’t add NOS to my car.
No comments. The best video I have ever seen! Sooo much too learn and sooo goood explanation.
OMFG, just what the Dr needed. A tutorial on Carb setup. Thank You, Thank You, Thank You.
I learned…..about a semester of community college mechanics
LOL sweet! That’s what I like to hear
I have never seen a better video on anything in my life ! Great job. I'm definitely saving this for later...
Dude 2 years later and still relevant i was scared to change my carb on my 2023 ruckus due to the jetting, have a performance exhaust, air filter delete, and pressure tube and all i needed was the performance carb now im going to change it and see how it goes thank you!!!!
The best video about this topic on the internet! Thanks you got us covered about all the questions 😀
Glad it was helpful!
Spinning backflip accomplished--subbed🤟
Thank you Rolling Wrench, i've seen videos about carburetor tuning and this is the most informative and helped me understand more easily. The demo shows that this was not based on books only. Appreciate this!
Thanks for the support! I appreciate you
the only guy that can actually explain things without making me think I'm stupid
That’s good to know :-)
Excellent video, man...I learned more about carburetion in the 35 minutes of this video than I had in the previous 48 years of my life...well done
53 years for me, including 30 of that in a maintenance capacity, you taught me more in 30+ MINUTES! Thanks Brother!
A friend shared this on Facebook. Well done 👍!
I'm 58 and have been messing with engines probably from around 7-10 years old. I've blindly "adjusted" carbs, and kinda gotten things to run okay. New Sub.
STILL the BEST video on RUclips... Thanks soo much for making this. i just did a zs190 swap on my Grom and your videos ALWAYS help
Best video on carb tuning ins and outs I’ve seen…hands down! Thank you bro
Heck yaaa! Thanks dude
I've watched a lot of tutorials about tuning carb, and by far this was the best among the rest. Best explanation ever made. Now I can do a lot better in working carburetor.
This was the best explanation about jetting. And I'm not mechanic. Got some knowledge all-around from my father's. And this is valuable for me because I'm setting up my 08 KLR. Got a Big Gun exhaust and k&n filter. Getting decel pops and idle mixture screw won't give me more flow. Running 2 turns , don't hear any increments. When I reach 3 1/2 turns, the bike shutdown. Let's do it 👍
Your instructions are truly amazing it makes a lots of sense because the needle controls every thing to make the engine gets a perfect performance, let me try that thing adjustments because the performance of my machine is so groogy, looks like spitting out so much gas, you're the best teacher on live performance
Thanks for the support 🙏🏻💯🖤
I learned a lot from this video! Every minute was worth it.
Put a carb I bought from you on my Tao Tao 50cc it was hard to start unplugged the auto choke it fixed the problem Thanks for the Learning Channel.
I am so happy you broke this down. I bought a Yamaha Virago 750 two years ago and did some cleanup including rebuilding the carbs and I know it can run better. Now I know just what to do. Thank you!
The front cylinder exhaust is almost non existing at idle but normal at cruising. Then when I get up to 65mph I am losing a cylinder which comes back when I slow slightly. This is a result of bad tuning, correct?
I bought a Rolling Wrench Carburetor 49cc 125 carb for my BBK build and it works perfect very happy with it best 65$ I've spent.
That was so informative. If someone is really interested on being a motocycle, ATV, UTV technician, this is not to long video. I'm thinking about getting that kit.
To be honest, for a beginner this is something to always come back and reference from. The skill will set in over time but this is really informative. I also learnt to be careful with gas on that "o" ring when you opening your carb. I also learnt that backfiring is not "rich" but "lean"... lol that really helps to know.
I'm working on my wpb and just cleaned the carb. You've earned a sub just for effort labeling the parts alone. Half way through the vid, very happy 👍
I learned that popping on decel is always a lean condition, thank you! I have a KLX250sf and it’s been popping since I bought it 10k mi ago (and with 10k on it) and I’m worried that I’m doing damage by running lean for so long and riding the piss out of it cuz it’s a 250. It has a fmf power bomb Q4. I’ve been thinking it never got jetted when the previous owner installed the pipe. This video is badass and you’ve got a new sub for life!
this is hands down THE best video on a carburetor on youtube! I'm buying a new motorcycle but it will be my first carburetor bike. This video is gold and will be in my favorites :D
I want to thank you for time and knowledge. This is one of the best videos I have ever seen.
Gotta say I really appreciate the level of detail. I just cleaned my 4 carbs and took the opportunity to re-jet my 2007 Yamaha RSV because I added Monster Ovals and K&N air filters last year. Since then, the bike only ran at 1/4 choke (Mikuni plungers). When I tore them down, all the jets were clear, but the float needle gaskets seats' seals were hardened and started leaking which is why I did the job. Went up from 15 to 20 on the pilot jets and from 115 to 122.5 on main jets in the front banks and from 123 to 125 on rear banks. (Something like that. Can't remember the exact original size on the rears. I still have all the original parts though). Set pilot screw at 3 1/4 turns.
Got it put back together, and she started right up with little initiall choke and ran strong at cruise speed or WOT but was getting afterfire and a little flame on the left pipe during deceleration, which I didn't mind much. Actually liked it, but didn't want it ruining anything or fouling the plugs.
Fast forward to 2 days later and it wouldn't run long on cold start. Choke didn't help but actually wouldn't run at all nor start with choke. So now after watching this video, I'm thinking I may have to lean out the idle circuit as I have a sightings better understanding
