My first reaction when I was looking for proper carb adjustment on this vid was, "How can even this help me?" Now that I have an idea I say, "WOW THIS HELPS A LOT!"
This video is humorous and very, very helpful at the same time. The sounds out of your mouth are spot on. I did the same thing when I explained my son how to tune his carb on his scooter. LOVE IT!
I very much liked your boldness and use of engine tones that indicate the type of engine complaint, as if he were a doctor distinguishing the type of baby’s crying, whether it was hunger or a desire to sleep.
Bro explained it better than the car videos I watched. I know it might be different for older cars but it’s helping me tune my carb on my gf Pontiac firebird. Appreciate you man
Shouldn't be different. Carbureted is carbureted, period. The only major differences in how some of them operate, is in the presence of absence of an accelerator pump. Acc pumps are designed to squirt an additional boost of fuel to mix with the sudden surge of available air when the butterfly snaps open and the venturi essentially becomes "unrestricted". The main jet can't supply enough gas quickly enough by itself to make sure that surge of air is at the proper AFR. But this information will apply to literally any gas engine that runs a carburetor as opposed to some variety of injection. Bike, boat, car, airplane, lawn mower, whatever. The base principles are the same regardless of the application. So any carb advice given in one specific application will generally be the same for any application. Cool that a bike video is able to help you with a car issue. 🙂
Dude you just saved me SO much time! I was misinterpreting my bike and thought the air:fuel ratio was too rich. I was going to spend all day tomorrow going down into smaller and smaller main jets in my carb trying to solve the bogging, but I would have been going in the wrong direction! Now I know what to do. Thank you so much!
I gotta give you a super big thumbs up sir, of all the videos i've search and seen, super long videos they didn't satisfy me on how to do these things. Your video is so short but explains everything that i need and you explained it for us/me to understand it so quick, been tuning my carb since this morning and after i saw your video, it just took me like 5-10 mins and its done!!! Thank you so much!!! More power and God bless!
Just got myself a 2T scooter and was think the previous owner might have moded it and put the old stuff back on and sold it to me. It does start and run but it just really has no power and doesn't rev out really, but the "rev limiter" you're talking about is EXACTLY what I heard when revving it on the kick stand. No others have really talked about that side at all so thank you for putting this up
The sounds you made finally helped me understand how to identify my issue. You made it so simple that even I who struggles not to drool on myself can understand.
this content is god tier. you just saved me so much time trying to guess whats happening based on everything ive read about carb tuning. the sound fx and gestures couldnt be more representative. thanks dude
@@MotocrossHideout oh it was just a saying! you know like above S tier haha. didnt mean to be disrespectful 😊 hey btw do you know how the hole number in the emulsion tube affects the carb seting? i came to understand every component and its effects but that one. i have from 4 to 32 holes for my carb and im pretty lost on the matter
it's a project bike. the carb is not stock so i dont have any default setting for my bike. i have to decide every setting by myself. hole quantity included. right noq everything is setted properly but i got bad throttle response, like lean bog when sudden throttle. i was hoping the right emulsion tube would fix that. i dont want to go for the acceleration pump
This video really helped me to realise my bog was due to fuel pressure. Oddly i think the low pressure caused it to run rich though, was guzzling fuel and popping and banging in the exhaust. Changed my in tank pump and filter as the brushes had broken down and fouled the filter bad. And then found my regulator was also stuck open. Went from 35 psi to around 48.
This just solved 2 separate bike issues in one shot!! My pit bike definitely has a lean bog and makes sense now. Added a nibbi and I’m positive the pilot needs to go up a jet!! Mint!!! And my kx250f may have debris/old gas residue or also needs a step up on pilot. I got the bike recently and it had sat a season with minimal starts by previous owner. So I need to check the pathway and if that’s not it it most likely the same issue. I’m sure it’s fuel related because he had receipts from a fresh top and bottom full build and had less than one hour on engine in nearly 2 years. So it’s either debris or possibly with the stage 2 hot cams and 78mm-83mm bore, fmf fatty 4.1 full it may not be getting enough pilot fuel. Because instantly after the initial bog it has ALL THE POWER and rips
Bro its so very helpful with all your splendid explanations from the bottom of my heart ♥. You just Speak the whole language of my bike. Thank you so much and i already downloaded two of your videos. I was looking everywhere for a mechanic to fix my bike but i don't come across any. Fact is we do not have any bike specialists or mechanics around here in my Province and district as not many riders are here. Therefore, thank you Lord for you are just a pill 💊 to my broken 💔 heart ♥. Why im saying all these because as a person from the third world country, i hardly find such a rare person like you to explain everything with such of your body gestures and simply English. May God continue to inspird you with lots of wisdom out there. ...
I bought a DRZ400, and your videos have been very helpful. Test riding it, everything seemed okay, but just in case, I have your terrific sound effects to go off of now!
We'll not talk about how outrageously big the main jet was in my DR350 when I replaced the carb. It's still a little rich overall but with a little luck and patience I'll have it nailed soon! Thanks for confirming what I thought was my issue.
Thanks, this video helps a lot. I have a lectron on my 02 yz250 and it has a lean bog, but ONLY when it is first started up before it has heat in the motor. Once it warms up a bit and gets some fuel through the carb it rips through all rpms.
I don’t know if you will get to this comment soon enough, but I am completely stumped I have watched countless of videos worked on carbs my self never had issues, this video is absolutely perfect and helps a lot but my problem is completely reversed on how u explained in the video. The bike is a yz250f 2006. Brand new carb, carb is tuned on a warm bike absolutely perfect idol, starts up first kick no bog, no chasing idol, perfect snap on the throttle it cracks it to the rev limiter and back to idol instantly. It’s like there is no problem but as soon as you put it in gear and start going it’s normal up until 20% throttle and then it stutters/rev-limits no acceleration. I slow back down and it goes back to normal but once I get those moving gear rpms up again it’s like I have a new rev limit and stutters a shit ton. I pull in the clutch and can rip it back no problem sounds perfect put it in neutral it’s perfect! But 1st 2nd 3rd all the exact same thing I’m stumped. I tried changing the main jet size and re tuning the idol and air fuel mixture screw but nothing. Just me taking a carb off and on only to get the same result. If you can help any it would be much appreciated. Thanks
Hmm, hard to say for sure. Have you checked the TPS? Maybe that came loose/moved. Did you buy a new OEM carb or Chinese knock-off? Also, did the bike run fine before this happened? If so, what exactly did you change?
My old 2-stroke Puch 50 used to do the lean bog thing with the stock pilot jet, but installing an Adjustable Pilot Jet fixed that, allowing me to fine tune it, giving rich when cold, lean when hot.
If it's getting that hot then it's probably too lean. Not sure what bike you have, but I would check for air leaks first - the intake boot/manifold could be cracked or the carb clamps loose.
I have a 4 stroke thats running fine below a certain RPM thresold but when it hits like 6000RPM it starts sputtering and not accelerating like you described when its running rich. But if i hold the throttle there for 4 seconds its like it gets past that point and starts accelerating hard. Is it running rich?

Dude those sound effects were exactly what I needed. You speak my language and that’s awesome.
Ha, glad you found it helpful. Thanks for watching!
😂 facts!
Thank you the info!
According to his sound effects I'm running rich. Lol
He took carburetor 4 in high school
Dude. This video might seem dumb to someone who doesn’t ride, but for the rest of us it should be included with the purchase of a bike. Thank you
Lol
My first reaction when I was looking for proper carb adjustment on this vid was, "How can even this help me?"
Now that I have an idea I say, "WOW THIS HELPS A LOT!"
You speak the universal language of moto! Thank you for breaking it down and going the extra mile
I try, ha. Thanks for watching, Robert!
Very educational. I was thinking my bike was running rich, until i saw this. Now i know its running lean. Well put together, thank you
Glad you found it helpful, thanks for watching!
For me completely the other way around lol
Sound effects EARNED my sub. Thank you for the video!
Ha, thanks for watching, Garrett!
Honestly after all my years of working on engines, your explanations have made more sense than anything I’ve ever heard.
same to me 🤣
We all need a man who understands engine language. Thank you for talking to us in braap, made perfect sense!
Couldn't have said it better.
Absolutely hilarious but very educational. Thanks!
Ha, thank you!
This video is humorous and very, very helpful at the same time. The sounds out of your mouth are spot on. I did the same thing when I explained my son how to tune his carb on his scooter. LOVE IT!
This is how you get subscribers, straight to the point and explaining in a way we understand
😊 This is actually very helpful, thanks for confirming the rich bog issue I'm having.
You're welcome, and thanks for watching!
Sound effects are really helpful to understand the differences, thank you!
Perfect. I’ve experienced most of these, but it’s amazing to have a single short video with perfect descriptions for all in one place.
Not a dirtbike rider but appreciated this video for my classic truck. Thanks man
Your rev limiter analogy made total sense. I'm not even working on a dirtbike, but am having carb troubles with a 67 bug and this video helped me.
I very much liked your boldness and use of engine tones that indicate the type of engine complaint, as if he were a doctor distinguishing the type of baby’s crying, whether it was hunger or a desire to sleep.

Your sound effects are spot on🤣
Straight to the point with no bs good vid!.
Ive been riding bikes my whole life, and your sound effects were right on! I laughed so hard becsuse i could relate so well
The sound effects in this video were the most useful information I've found on this subject so far!
Hollywood should hire him for the sound effects
Your sound effects are amazing man haha
Glad you think so - thanks for watching!
New to carbs and this helped me more than you'll ever know.
The fact he’s using sound effects makes my life so much easier 😂 respect for this video 😂 I’ve got a lean bog
I gotta give you a super big thumbs up sir, of all the videos i've search and seen, super long videos they didn't satisfy me on how to do these things.

Wow, that's quite the compliment - thank you, and I'm so glad you got it figured out! It sure is frustrating when the carb isn't dialed in...
Your verbal illustrations really help identify all the bogging situations! Great Video
Glad it was helpful!
I ve never rided a bike... I am able though to give tuning tips to riders while waiting in the car.. thanks to this great video..!!!

Big big help. Simple, to the point, and greate sound effects that actually made sense. 10/10
Thank you. I just used this to tune my scooter and it is really helpful.
Glad it helped!
Excellent noises. I knew exactly what you were referring to every time.
Boom!! Finally someone answered my questions about that four stroke bog!!
Brilliant, really needed to understand the lean issues/sounds, thanks
You're welcome, thanks for watching!
Thanks for the video, just picked up a couple bikes and it's been forever since I've messed with a carb, so this was a much needed refresher lol
best explanation WITH EXACT SOUNDS
Thank you Boss! Your videos help me to tune a cheap 28mm carb into my 125cc scooter
I'm tuning my 125cc scooter bumped to 175. This dude's sound is accurate and much needed 🤣
best explanation
I would recommend the video to everybody, and i'm sure everyone will understand
This is the best explanation I've ever heard.
Dude i have been searching for information on a rich bog for days any everyone would say its lean but my plugs were black. This was awesome!
Those sounds are the ones I am lokking for. Thank you soo much. I have a rich bog. Gonna fix it
This video really helped me to realise my bog was due to fuel pressure. Oddly i think the low pressure caused it to run rich though, was guzzling fuel and popping and banging in the exhaust.
Changed my in tank pump and filter as the brushes had broken down and fouled the filter bad. And then found my regulator was also stuck open. Went from 35 psi to around 48.
Thanks for be a humble human and simple sound explanation....💯
This is a great video and what makes it better is your spot on sound effects, lol. Time to go drive the family nuts making these sounds today.

Man, loved the way you described how it feels so easy to understand,
Nailed the sound effects bro
bro those sound effects with the facial expressions got it more understandable,
nice presentation, gotta love this kind of explaining 😁
I gotta work on my dirt.Bike sounds you've mastered it
Really diggin the scientific approach of this video ;)
You speak dirt bike so well! This was a very good video thanks!
Finally got my single carb swapped Virago dialed in, this video helped a lot
Day 8,469 of coming back to this exact video. Gr8 video!
I spent years racing two stroke radio controlled cars at national and international level. Everything you said is spot on, even for the tiny ones. 😂
This is one of the best carb issue videos out there. The sound effects are spot-on. Now I know that the carb on my girlfriends TW200 is too lean.
Glad you found it helpful - now go get her bike running like a champ so that she will enjoy riding more!
@@MotocrossHideout I think that she loves riding more than I do, and she has four other bikes to keep her busy!!
Oh wow, quite the fleet!
Super useful info, love the engine impressions. Genuinely really helps drive the points home
Finally someone I can relate. Thanks sir😊
hahahhaaa your killing me doing the sounds and sound effects!!!! keep up the good work and you gave me a great laugh in the morning
If it does "crazy frog sounds" the mixture is too rich.
Im barely getting into mini bikes, gas scooters and you did an awesome job explaining it was also funny lol thanks 🙏
The time he make that sound i know I'm in the right video.
Thanks man 👍
Thanks for making it soo simple! Love the sound effects 😅😎
Dude this is awesome thank you so much

Haha, congrats on your new bike!
This helps me a lot on my ATVs I have a 4 and 2 strokes that aren’t running right
thank you for info😎😎😎
Great description and sound effects to explain the difference.
I love explaining things with sounds. Lean is always "Booooowwwww....." 😂😂
Man your sound effects are right on!! 🤣 I didn't need anymore info after that lol..perfect bro 🙏🏾
We'll not talk about how outrageously big the main jet was in my DR350 when I replaced the carb. It's still a little rich overall but with a little luck and patience I'll have it nailed soon! Thanks for confirming what I thought was my issue.
Why did I just found you now??? All these mechanics yet non of them solved my problem. But you, sir, with the heck of a mouth sound effects, did.
Ha, thanks for watching!

dude really deserves a Grammy Award.
That's the kind of explanation that i needed. Thanks man. Keep it up !!!
No problem - thanks for watching!
The simulated sounds cracked me up but are also incredible helpful
Amazing videos and sounds are perfect the only video that made sense to me and now it is tuned properly and running amazing
Best diagnosis vid ever
only video that explains the exact symptoms
thanks for the sound effects that helped because i do the same thing !!
This was a great video straight to the point and quite amusing too well done
Best explanation ever bro.

Also, did the bike run fine before this happened? If so, what exactly did you change?
Perfect example thank you for the reference
Thank you for this, I will be referring customers to your video! I've not quite been able to articulate the nuance of tuning so well as you, friend!
You're very welcome - thanks for watching!
Those sound effects are awesome haha
The sound effects may be from THX, but for an mateur begginer mechanic like me, makes the bike response more understandable and easy to fix. Thx!

Nice, thanks for watching!
I love the sound effects! Thank you you earned a sub
If it's getting that hot then it's probably too lean. Not sure what bike you have, but I would check for air leaks first - the intake boot/manifold could be cracked or the carb clamps loose.
Then sound effects helped me understand more of my issues thank you
I know this signs but I don’t know how to demonstrate it to my friends. So this helps. Straight on target symptoms.
I cant give enough thumbs up for this video.
This is the perfect video
thanks for the knowledge 10/10 sound effects as well
Thanks! Will try to rich it up!
You're welcome - let us know your results!
I have a 4 stroke thats running fine below a certain RPM thresold but when it hits like 6000RPM it starts sputtering and not accelerating like you described when its running rich. But if i hold the throttle there for 4 seconds its like it gets past that point and starts accelerating hard. Is it running rich?
Yes, sounds rich. Either the needle or main jet is too rich. I'd try lowering the needle (raising the clip) 1 position and see if changes.
that sfx is top notch.
