Man, this video really hit the spot for me. I got a Nibbi carb for a Yamaha I got without the factory carb on it. You just filled in the blanks for me as to why my bike is idling so high. Well done!
I do have a question, If your slow jet is big, will it make the idle stay high? I'm having troubles getting my bike to idle low. Wondering if my slow jet might be big.
No problem glad I could help I definitely wanted to make it easy for everyone to understand. Plus I had a hard time finding anything that explains this process good.
Hey man can you do a video on adjusting the idle on the knock off mikuni? So many people want to see this because mostly everyone has the amazon one. That would be soooooo helpful!
Why the best carb for your bike is the one that will come on it! Don't through it away a nibbi carb adds no value to a bike ads like stock parts? Having said that I done the same thing let people convince me it's the first thing you should do! Add see how it rides first try resetting your stock carb!
Needle jet is for like 1/4 - 3/4 throttle the needle is tapered so that as you open the throttle it meters the amount of fuel coming through the main jet
Rejetting at different altitudes while riding in the mountains seems like a pain in the butt. Wish I knew how easy or tough it would be on the XPro Hawk250.
I've been able to only tune my carb very basically and just got a new one, which so happens to be a nibbi and never really learned about the jets and inside of a carb besides cleaning them. This helped alot appreciate it
Omg I am driving home right now and cannot wait to try adjusting the air screw first. The idle and tuning my PE 28 has been driving me insane. I hope and I think that this is going to help! Weeehooo
Can you adjust the throttle position? I feel like mine is closed and on start (maybe it should be) but it bogs and dies. Could be turning I’ll try this.
You always start with the main jet, then work your way towards the idle circuitry. Main jet is full throttle. Midrange is dependent on your " JET NEEDLE" Position. Low end on the pilot jet size. And idle with the air/ fuel mixture screw. Which is set at idle, for the highest idle point. Which can be one to three turns out. Any further then three you need to upsize the pilot / slow jet. Which is where you usually get low speed "BOG" if not enough fuel during rapid off idle runs. Float height is very critical, and common knowledge is to always get sparkplug readings for both cruise, and full throttle blasts.
You got it right on point. All my carbs had to adjust the float and on some vm22 I had to adjust slightly higher for the pilot to pick up. Somehow the design had a flaw and the pilot kept screwing inside the carb to the tread and not the seat.
Dude, thank you so much. This saved my bike. I bought an RPS Hawk 250 as a project bike and for my commute to work, and put a Nibbi on it. I have ZERO experience with any kind of small engines/carburetors, and after I first installed the Nibbi it was idling at 4500RPM and would bog down/cut out with any acceleration. I was panicking, but thanks to your video I got it tuned perfectly. Idling at 1200rpm, zero stuttering/bogging throughout all acceleration, and its running BEAUTIFULLY. Thank you so much again!!
Hi . I’ve got the nibbi pe26 on my thumpstar 125cc pit bike 2021 model and it’s a Lafan Engine . I’m having trouble with bogging towards the top end of the throttle .

I Hava a NIBBI Racing Performance Carburetor 32MM Motorcycle Carburetor, would you know where the two hoses on the side of the carb leads to or where it should be connected to on my 250cc motorcycle? I know where the standard hoses, like fuel and bowl lines connect. But the hoses on the side have me at a loss.
engine is a 165FMM (230cc) Valves both at 0.10mm carb is a NIBBI PE28FL with a pod filter. Needle is as high as it can be, (5 slot) air screw is exactly 2 turns out 42 pilot 115 main Slight bog off idle and screams everywhere else. Any deviation up or down on the jetting makes it fall on its face. Line on the side of the float is exactly parallel with bowl flange when upside down How the hell can i get that last little bog to go away. Sucks big time when you need to pop that front end up, and it hesitates. bringing the needle down makes it terrible on the bog, larger pilot one size up (45) and need in any position is terrible. same if i go down one size on the pilot (40) Have to fully remove all plastics, seat, and fuel tank to mess with the needle, and carb with intake manifold has to be removed for jetting. Spent almost 16 straight hours getting it where its at now. Bike is brand new, only 40 miles on it. Original carb was a PZ30 china clone and non adjustable.
I have a question nobody else seems to have an answer I'm looking for the clip not the e clip that holds the needle but the one that shaped funny and holds the whole needle and eclip to the round slid on a nibbi 26 mm cant find one since I've been watching your videos you were the one person I thought might would know
That's not a fuel screw, it's a slide height screw. It's your idle level screw, it lifts or lowers your slide which gives your engine more or less air. The pilot air screw changes the fuel mixture at idle. You have a good hold on what's happening with the carburetor. Good advice to newbies. Good job!
Cool video but for a 125cc you have a nibbi pe22 how the heck did you end up at #48 #120 I have a 160 and am panicking #38 #118 is to rich on a pe26 my 140cc runs so good with a pe24 #37 #115 my pe26 was running great till about a week ago now I'm stumped?
when you say change the jets do you mean physically taking the carb apart and unscrewing the jets and screwing new ones in? I just ordered a pe28FL carb and im wondering if its just plug and play with a little adjustment or am i going to have to buy different kinds of jets to get my bike to run properly
I only get bogging when I try to throttle fast and hard right away I’m new to this but I’m guessing that would be the pilot jet? I’m at about 50ft elevation (this is for the nibbi carb) really need help with this
I have a stock SSR 125, but my main jet seems to be much longer than any jet kits I find online? Know what specific jet form factor I have so I can find the correct one? I have a 38 pilot that is short and round. 85 main that is longer than the typical results online. Im bogging from idle to WOT transition. I assume my main is undersized.
I've put a nibbi pe26 on my z155 engine and getting backfire. Would you recommend going up a size or down a size with the jets. Also what jets would be right sizes?
@@throttlefamily4655 Really? Thanks, I was just about to spend the extra money and get the Nibbi too! I would have thought after you finally tuned it, it would have been better than the knock off mikuni but guess not?
@@throttlefamily4655 One thing I didnt hear mentioned is the carb size. Was you engine stock? If it was 28mm might have been a strong factor why you came to the "not that good'" conclusion.
I just installed my nibbi carb on my 250cc Templar X Pro 4 stroke and I'm about to start it up so we will see where the idle screw and fuel screw helps.
hey question i have a nibbi kit 28 mm 150-250cc carb with 48mm air filter kit.I cant for the life of me find where the idle screw is.Bike runs fine but dies at stop signs and lights unless i leave the choke plunger open. Or warm it up for like 15 minutes.
What jets u running I have the 24mm 115 main 45 pilot and it goes good but when I go to flip the throttle in neutral itgoes to bogg out on me dosent die but just bogs
Just installed my nibbi carb and the idle sounds real high that my exhaust pipe coming out the head started glowing red what can i do Its on a apollo 125
I have the knockoff Mikuni VM22 and get aggressive bogging in 2nd gear and such (seems mostly anything more than 15-25% throttle so definitely main jet). Ride in 7,800 to 9,000 foot elevation mostly; how would one go about getting jets for the knockoff Mikuni?
@@throttlefamily4655 THANK YOU!!! That is going to help an absolute ton. I got my Uni air filter installed to my carburetor, tuned the fuel mixture screw and throttle clip, and the bike now runs only on choke but goes through all the gears perfectly on choke. Doesn't idle and still bogs without the choke regardless of idle screw adjustment and such so adjusting to a bigger pilot screw seems essential! I'm gonna open my carburetor up and potentially come back with jet sizes. Thank you, again. VERY much appreciated.
@@throttlefamily4655 By default mine had a K38 pilot and K95 main. Definitely great bogging through the throttle range without that choke. I looked on Amazon and these keihin jets have mixed reviews for the Mikuni knockoff. Some say only the main jets fit and others say they're not working at all. Do you have any recommendations for getting a jet kit?
i just got a nibbi 26mm carb for a 140cc lifan dirt bike swapped. It comepletly bogs when i give it full throotle fast if i do it slowly then its fine, it comes stock so idk what it has it came with 3 extra jets a 35 pilot jet, 108,112,118 main jets i live around 50 feet elevation what should i do? ive tried the air/fuel mis screw and idle screw and nothing works, help
This carburetor is very difficult to set up you may like the mikuni knock off a lot more it’s a lot more user friendly this carburetor took me a few days to get dialed in
What jets would you recommend for a yx140cc engine. I have a 112 main and I’m getting popping from the exhaust on deceleration and partial bog at anojt 1/4-3/4 throttle
Popping on deceleration is a lean state try one or two sizes richer on pilot jet, As for the bog maybe try the needle jet one clip up from position you are currently running.
I need help with my carburetor on my 125 cc Coolster dirt bike. The exhaust was off and it caught fire for about 10-15 seconds and only 2 of the breather tubes got burned at the ends. I’m confused on the one nearest to the choke. It looked like a very short tube just for overflow maybe? Not the one that goes downward and it wasn’t the fuel lines. It was a very short one and it’s still connected the ending is just closed now from the flames. And I put the exhaust on so the flames it was spitting doesn’t hit the the gas that was leaking. I’m gonna replace the carburetor next week but for now Please help me out yall! I’m new to bikes.
@@throttlefamily4655 i tried my heart out trying to get the 26mm to work, so i went with a smaller one the 24mm nibbi, i believe it will work better since the 26 is just too big. Wish me luck.
Hi bro. I have problem with starting engine. 140cm3, Nibbi24 stock jets 112 and 40 and it is hard to start it. I have to kick it with chocke and then trying without it. If it starts I have to hold throttle until it will be hot. How to solve it?
Yoo, I would really appreciate it if someone could send me a name or link of the manifold.... Got the same nibbi carb but I just realized my old one has mounting holes for screws. The nibbi one needs a tube... So I'm missing a manifold from the engine to the carb with a end piece to put a tube and a clamp like in this video
For my bike I installed it how it was set at factory, it kicks on no problem but doesn’t want to stay on without me having to give little throttle bumps. What do you suggest I need to adjust?
I installed the knock off mikuni on my db14 110 and I for the life of me could NOT get it to run right. It would rev to the moon all by its self. I ended up going back with the weak ass carb that came stock on it.. lame AF what the hell could I possibly be doing wrong here?
Two things here could be your problem one you didn’t have the cable installed right on the top or two you could have put the slide in wrong I face timed another subscriber and the second one was his problem he had the slide in 180 degrees backwards
Problem I’m having with mikuni knock off . Bike ran and idled great for a few months. Now it runs great as long as your giving it gas. Let off the gas it won’t idle. Adjusting the idle higher don’t help. Plz help
You will need to take the jets out and clean them I have to do that every once in a while as well I will be posting a video tomorrow that will have it explained in the video
Huge thank you for this video brother. I know nothing about engines but bought a used grom clone with a faulty carb. I followed your instructions on the install and tuning to the tee and it worked perfectly! You just made my weekend, huge thanks again!
@@throttlefamily4655 you vid is really helpful I was messing with the settings on a diff carb and kept getting the hesitation on the 1/4 turn when reving. When I start it again tomorrow I’ll play with the fuel mixture screw to see if I can fix it.
Why do most people buy the mikuni knock-off carb when you have the adjustment screw on the bottom of the carb. Pain in the arse to have to keep taking the thing off to adjust.
I bought a nibbi pe26 for my kawasaki klx 140r. I've tried different needle clip positions, different size pilot jets (35 & 40), and different size main jets (105, 108, 110, 112). In all scenarios I can get a good idle, I can get steady midrange rpms, and I can get steady full throttle rpms. In each of these scenarios I have a rapid throttle bog. In other words, from idle, rapidly twisting the throttle I get a bog. Although it won't bog moderately twisting the throttle. Any ideas?
Hi...good day... Im cary from the phillipines How can i get a rigth tune of my carburator...i own a honda.beat carbtype scooter...from 110 cc to 120 cc...carb i use is nibbi 24mm The main jet 112 slow jet 32...
Well it sounds like you are on the right track personally I like the knock off mikuni from amazon they are much better and only cost around $35 and are very easy to tune you will probably be spending more money in time with tuning and jets then it is worth.
Great video man ...I just installed the nibbi on a hawk 250 and it wont start ...I smell fuel like crazy and probably need a smaller pilot jet ...not completely sure at all but I'm trying stuff ...do jets need to be screwed in all the way.. I have no clue about that either...any info would be great
@@throttlefamily4655 I got it right finally ...my bike (2021 hawk) loves this carb ..got more speed more power starts 1st time everytime , it's good stuff ...ur videos helped alot ...thanks man ..ride on !!!
I recently replaced my carburetor to a “Mikuni” I bought off Amazon. My issue is the bike bogging in those higher RPMs. Dude you explained everything I need to know unlike other videos I’ve watched where they explain one thing, but not the other. Thank you!!
@@throttlefamily4655 I’m referring back to this video because I’m having carb issues again. Im bogging out on top gear (4th gear) my main jet is at 125 and pilot at 38. I have no issues with idle at all. Only when I get to higher rpm the power is just crashing. I even went as low on my jets to see if it will help.. low as 88 on my main jet. I messed with the needle. Pretty much did everything. I have a new spark plug.. recently changed the oil. Anything you recommend?
@@nicholassaldanatuning a carb can be a big pain in the but and specially when your new to it. I hade also the problem that my bike ( 2 stroke ) would not get in to its powerband. After trying idk how many jets and try a lot of different needle heights. I was slowly getting there. Some times it can take a couple evenings to get it right specially when your new to tuning carbs. Just try and try and probably you will get it right one time. Just watch out that your not running to lean so you don’t damage your engine. 😉😉 that 2 stroke was my first time tuning a carb. But afterwards if heard that ingaf a carb and air filter that where hard to tuning in and get it right 😅😅
@@briantruax1682 yea I looked it up it’s exactly 2 1/4 for air n gas is 2 3/4 for proper tuning to start at 2 out is just a basic start which most ppl do 2 n half turn
U need to do plug cops at idle ,mid range and full throttle to completely tune your carb with a new plug ever time because a plug don't lose color wants it has it so if u want to take it to the next level thats your next step
Hello I need some help with my ssr125cc i have the real vm26-606 mikuni and I can't find anyone to help me jetting it any recommendations would be greatly appreciated thanks
throttle family okay I think I got the carb adjusted properly, but the Engine bogs and dies wen I give it throttle, do I change my needle jet or main jet?
@@throttlefamily4655 Do you have a insta at all? I'd quite like to send you a video and ask for some advice if that's ok? I'm new to this and I tried adjusting my carb and made it worse 😅
my pitbike runns way too high rpm in neutral and when u ride it it feels like you ride a 80cc but its an 160cc.... what jet do i have to adjust and how much rotations.... i was told to habe the two main jets in the middle all the way in.....
No, if you're talking about the pilot jet, the one on the side of the carb, ideally you want to be around 2 turns out. Fully in should make the bike cut out if not your pilot jet is too rich and need a smaller one. If it bogs on full throttle u need to put a different size main jet, midrange is on the needle which you can adjust needle position to run richer or leaner... Your spark plug will tell you all you need to know on how your bike is running, if to rich or to lean
I just put a new exhaust on my KP MINI 2 days ago and have a nibbi carb. Its still running okay.. Its back firing every now and again when I get on the throttle. Also, Is it normal to have to kind of roll into the rev? If i go from idle and just pin the throttle my bike will bog of stall... if I give it a couple quick revs its fine and when I am out riding I can just send it.. full pinned. EDIT: as I got deeper into youre video you touched on exactly what I needed to know! Thank you! I want to go mess with my carb right now but now I am terrified of messing with that thing. I would also like to add that your explanation on the mechanics and function is amazing
I have the knock off Mikuni which worked on my ssr 110 perfect but on my 125 I have to turn the idle screw so far out that its rattling loose so that it isn’t idling crazy high
Lower your pilot jet. I just got the carb and my bike was idling high with the Jets that came in the carb it’s a PE28mmFL stock 112 main jet 40 Pilot. I went down to a 35 Pilot and now I’m actually able to idle normal. Gotta do a couple more adjustments but other than that I’m Gucci.
I really don’t know you are going to have to experiment with jet sizing but if your using the nibbi believe a 42 pilot 110 main should be close but I’m not 100%
@@tylerwells8640 I'm using a pe28 nibbi on a dbx1 140cc at 550 elevation and find that anything below a 40 and a 118 does not work well for me In fact I'm going to try a 125 or 130 main and a 48 or 50 or 55 pilot due to the elevation but I will play around since at the moment my mixture screw has to be way past 3 turns and at top end I get abit of hesitation so I know I have to raise the number ,, the 115 and 35 work like crap .
Just installed my Nibbi and set it at the baseline setting you used. Idles good with choke off but its cutting off over half throttle blip. Haven't changed the jets yet, would I be running too lean or too rich? Just unsure where to start with changing jets, and which ones needed to change.
@@throttlefamily4655 Ok I'll try that setup and see what it does. With the knock off mikuni did you have to change jets with it? If not do you think the fake mikuni jets would fit in the nibbi?
I just ordered a pwk 28mm for my 1977 Yamaha dt100. It is supposed to come with the right jets and screws. I see a lot of confusing info that this carb doesnt work with a 2 stroke. Are people saying that the two stroke oil reservoir cannot be hooked up to the carburetor? If thats the case, do you just mix the 2 stroke oil straight into the gas tank instead? Or are people just posting bad information. This seems to be hard to figure out how everything gets swapped out and adjusted. This video helped with a lit though, thanks.
Hey, can you send me the link for the adapter? My Amazon Knockoff carb is sadly junked, looking to buy a Nibbi 24mm for my 2019 Apollo 125cc X-18. I would go with a genuine mikuni but god I HATE how the tuning screw is on the bottom. So going with the Nibbi. But yeah if you could send the adapter link i would applrexite it
I took my carburetor apart and originally it was to make sure that there was no blockage within the Jets before this my bike did not start and after my bike started and would turn on only with the choke and I would have to rev it to keep it running what do you think is my problem?
@@throttlefamily4655 do you know if the pilot jet and main jet inside the carb should be screwed all the way in or just until its snug or should they be turned out by 1 turn or 2 because I took them out to clean and put them back in but I tightened them all the way now bike starts up really high revs
If you're gonna give hundreds of people advice...you should REALLY work on your terminology. You're calling tabs and clips, pins...you're calling grooves, rivets...you're calling the idle screw, the fuel screw...you're saying press down instead of bend. I heard SEVERAL things that are totally incorrect terminology. You've got the mechanics and operation of a carburetor DOWN PAT!! Seriously my dude, YOU KNOW YOUR SHIT...but your terminology is WAYYYY OFF. It could EASILY confuse a newbie that is trying to tune his/her bike. I think you just need to slow down and think about what you're saying. It just seems like you're getting in a hurry and spitting stuff out. Keep up the good content 👍
I have a 125cc but didnt came with the correct carb it doesnt have power it came with a PZ20 chinese carb but i have ride other bikes like mine an they have alot more power than mine am odering a PZ25 do u think that will do a better job? Or if it those not i will jus have to order main jets.

I have a question nobody else seems to have an answer I'm looking for the clip not the e clip that holds the needle but the one that shaped funny and holds the whole needle and eclip to the round slid on a nibbi 26 mm cant find one since I've been watching your videos you were the one person I thought might would know
That's not a fuel screw, it's a slide height screw. It's your idle level screw, it lifts or lowers your slide which gives your engine more or less air. The pilot air screw changes the fuel mixture at idle. You have a good hold on what's happening with the carburetor. Good advice to newbies. Good job!
Fuel screw = idle screw/slide height. Beautiful work
Which direction would lower idle speed?
@@connordillon1312 left
what kind of carberator I this so I can get me one
@@AC-nr8kk the exact carb he’s using is linked in the description 👍
So what the air fuel screw before you turn it a half and then fullturn do you want it all the way in?
Cool video but for a 125cc you have a nibbi pe22 how the heck did you end up at #48 #120 I have a 160 and am panicking #38 #118 is to rich on a pe26 my 140cc runs so good with a pe24 #37 #115 my pe26 was running great till about a week ago now I'm stumped?
Is it the stock jetting you used or did you change the jetting in the nibbi??
Changed it
Hey so wat if the problem is when giving it throttle it revs up, but when releasing throttle its still revving high
Love all the carb videos i just got a 125tr with a 140 piranha conversion and ive been trying to get it running right
What jets
Got the same problem with that same motor. Did you ever fix it up?
I have the same set up and would love to know what size jets and what size Nibbi you are running
when you say change the jets do you mean physically taking the carb apart and unscrewing the jets and screwing new ones in? I just ordered a pe28FL carb and im wondering if its just plug and play with a little adjustment or am i going to have to buy different kinds of jets to get my bike to run properly
You should do a things to know about dirtbikes video like the simple maintenance
That zip tie in the camera almost had me thinking a driveway drain was in the frame but it’s just a zip tie 😂
I only get bogging when I try to throttle fast and hard right away I’m new to this but I’m guessing that would be the pilot jet? I’m at about 50ft elevation (this is for the nibbi carb) really need help with this
Yes that would be the pilot jet
I know you said you use 120 and 48 but your at a higher elevation so should I be running bigger?
Thanks alot got my Gy6 150cc Running Smoothly got full Nibbi kit installed today 😅😂😊.. super 😎 Cool.
I have a stock SSR 125, but my main jet seems to be much longer than any jet kits I find online? Know what specific jet form factor I have so I can find the correct one? I have a 38 pilot that is short and round. 85 main that is longer than the typical results online. Im bogging from idle to WOT transition. I assume my main is undersized.
I've put a nibbi pe26 on my z155 engine and getting backfire. Would you recommend going up a size or down a size with the jets. Also what jets would be right sizes?
So what's the final verdict, is it worth tuning the Nibbi or just going with the knock off Amazon mikuni?
Get the knock off amazon mikuni
@@throttlefamily4655 Really? Thanks, I was just about to spend the extra money and get the Nibbi too! I would have thought after you finally tuned it, it would have been better than the knock off mikuni but guess not?
Tony Alves yea they are not that good I even ordered a knock off mikuni for mine
@@throttlefamily4655 One thing I didnt hear mentioned is the carb size. Was you engine stock? If it was 28mm might have been a strong factor why you came to the "not that good'" conclusion.
Should I buy this brand?
I'm also digging on that DC2 Integra with a JDM front swap.
I just installed my nibbi carb on my 250cc Templar X Pro 4 stroke and I'm about to start it up so we will see where the idle screw and fuel screw helps.
Hey man I have a 127cc engine, what do you think is the optimal size nibbi carb to run..?
What does your plug look like? You never showed.
What is the lever at the top
hey question i have a nibbi kit 28 mm 150-250cc carb with 48mm air filter kit.I cant for the life of me find where the idle screw is.Bike runs fine but dies at stop signs and lights unless i leave the choke plunger open. Or warm it up for like 15 minutes.
I’m not to familiar with the 28mm carb sounds like the pilot jet may be too big considering it takes a while to warm up
@@throttlefamily4655 ahhh makes sense thanks
Love the vids
Thank you!
On the nibbi pe30 do I take out the little plastic cover that’s over the main and pilot jet
Yes you do have to remove that when changing the main jet
Ty brother these dam nibbi carburetors a pain in the a$$. Just had to drop the main jet down thanks helped me alot
What jets u running I have the 24mm 115 main 45 pilot and it goes good but when I go to flip the throttle in neutral itgoes to bogg out on me dosent die but just bogs
Just installed my nibbi carb and the idle sounds real high that my exhaust pipe coming out the head started glowing red what can i do
Its on a apollo 125
Adjust the idle screw but you may need to put a smaller pilot jet in
@@throttlefamily4655 the main jet
If your exhaust was glowing its definitely a too lean problem.
I have the knockoff Mikuni VM22 and get aggressive bogging in 2nd gear and such (seems mostly anything more than 15-25% throttle so definitely main jet). Ride in 7,800 to 9,000 foot elevation mostly; how would one go about getting jets for the knockoff Mikuni?
They use the Kiehn size jets and you can get them off Amazon
@@throttlefamily4655 THANK YOU!!! That is going to help an absolute ton. I got my Uni air filter installed to my carburetor, tuned the fuel mixture screw and throttle clip, and the bike now runs only on choke but goes through all the gears perfectly on choke. Doesn't idle and still bogs without the choke regardless of idle screw adjustment and such so adjusting to a bigger pilot screw seems essential! I'm gonna open my carburetor up and potentially come back with jet sizes. Thank you, again. VERY much appreciated.
@@GamingWithFusion your welcome and you are definitely on the right track 👍
@@throttlefamily4655 By default mine had a K38 pilot and K95 main. Definitely great bogging through the throttle range without that choke. I looked on Amazon and these keihin jets have mixed reviews for the Mikuni knockoff. Some say only the main jets fit and others say they're not working at all. Do you have any recommendations for getting a jet kit?
@@GamingWithFusion they have worked for me also I believe I was running a 42 and a 115 but I can’t remember off the top of my head
Mine idles and runs great but when im in gear it sputters between ¼ and ¾ throttle. How can i fix this
i just got a nibbi 26mm carb for a 140cc lifan dirt bike swapped. It comepletly bogs when i give it full throotle fast if i do it slowly then its fine, it comes stock so idk what it has it came with 3 extra jets a 35 pilot jet, 108,112,118 main jets i live around 50 feet elevation what should i do? ive tried the air/fuel mis screw and idle screw and nothing works, help
This carburetor is very difficult to set up you may like the mikuni knock off a lot more it’s a lot more user friendly this carburetor took me a few days to get dialed in
@@throttlefamily4655 well maybe but what do you think I can do to my existing Bobbi carb? Should I change the main jet?
What jets would you recommend for a yx140cc engine. I have a 112 main and I’m getting popping from the exhaust on deceleration and partial bog at anojt 1/4-3/4 throttle
Having same problem. Did you fix it up ? Could use that info
Popping on deceleration is a lean state try one or two sizes richer on pilot jet, As for the bog maybe try the needle jet one clip up from position you are currently running.
Also my bike is only working with the black twist knob (I think it’s the choke) pushed in. I pull it out and it turns off
In is choke off
Whats your elevation?
I need help with my carburetor on my 125 cc Coolster dirt bike. The exhaust was off and it caught fire for about 10-15 seconds and only 2 of the breather tubes got burned at the ends. I’m confused on the one nearest to the choke. It looked like a very short tube just for overflow maybe? Not the one that goes downward and it wasn’t the fuel lines. It was a very short one and it’s still connected the ending is just closed now from the flames. And I put the exhaust on so the flames it was spitting doesn’t hit the the gas that was leaking. I’m gonna replace the carburetor next week but for now Please help me out yall! I’m new to bikes.
Thank you bro
Your welcome
Hi im rocking the same tune as you with the 48 pilot and 120 main, do you get a bog whipping the throttle from idle to full?
I was not after I tuned it but I have since then swap to other carburetors
@@throttlefamily4655 i tried my heart out trying to get the 26mm to work, so i went with a smaller one the 24mm nibbi, i believe it will work better since the 26 is just too big. Wish me luck.
Hi bro. I have problem with starting engine. 140cm3, Nibbi24 stock jets 112 and 40 and it is hard to start it. I have to kick it with chocke and then trying without it. If it starts I have to hold throttle until it will be hot. How to solve it?
Yoo, I would really appreciate it if someone could send me a name or link of the manifold.... Got the same nibbi carb but I just realized my old one has mounting holes for screws. The nibbi one needs a tube... So I'm missing a manifold from the engine to the carb with a end piece to put a tube and a clamp like in this video
For my bike I installed it how it was set at factory, it kicks on no problem but doesn’t want to stay on without me having to give little throttle bumps. What do you suggest I need to adjust?
I installed the knock off mikuni on my db14 110 and I for the life of me could NOT get it to run right. It would rev to the moon all by its self. I ended up going back with the weak ass carb that came stock on it.. lame AF what the hell could I possibly be doing wrong here?
Two things here could be your problem one you didn’t have the cable installed right on the top or two you could have put the slide in wrong I face timed another subscriber and the second one was his problem he had the slide in 180 degrees backwards
Problem I’m having with mikuni knock off . Bike ran and idled great for a few months. Now it runs great as long as your giving it gas. Let off the gas it won’t idle. Adjusting the idle higher don’t help. Plz help
You will need to take the jets out and clean them I have to do that every once in a while as well I will be posting a video tomorrow that will have it explained in the video
where do i buy pilot screw for this carb mine bogs 0-1/4 throttle
Xeby’s shenanigans you can buy them on amazon
Huge thank you for this video brother. I know nothing about engines but bought a used grom clone with a faulty carb. I followed your instructions on the install and tuning to the tee and it worked perfectly!
You just made my weekend, huge thanks again!
No problem I’m so glad to hear I could help
@@throttlefamily4655 you vid is really helpful I was messing with the settings on a diff carb and kept getting the hesitation on the 1/4 turn when reving. When I start it again tomorrow I’ll play with the fuel mixture screw to see if I can fix it.
Why do most people buy the mikuni knock-off carb when you have the adjustment screw on the bottom of the carb. Pain in the arse to have to keep taking the thing off to adjust.
I bought a nibbi pe26 for my kawasaki klx 140r. I've tried different needle clip positions, different size pilot jets (35 & 40), and different size main jets (105, 108, 110, 112).
In all scenarios I can get a good idle, I can get steady midrange rpms, and I can get steady full throttle rpms.
In each of these scenarios I have a rapid throttle bog. In other words, from idle, rapidly twisting the throttle I get a bog. Although it won't bog moderately twisting the throttle.
Any ideas?
Sounds like you need a bigger pilot jet Try one size up to 42.
Hi...good day...
Im cary from the phillipines
How can i get a rigth tune of my carburator...i own a honda.beat carbtype scooter...from 110 cc to 120 cc...carb i use is nibbi 24mm
The main jet 112 slow jet 32...
Well it sounds like you are on the right track personally I like the knock off mikuni from amazon they are much better and only cost around $35 and are very easy to tune you will probably be spending more money in time with tuning and jets then it is worth.
My bike only runs on the choke after putting the nibbi on and won’t idle down, help???
My bike will only run with my hand over where the filter should be but doesn’t want to stay running idk what’s wrong with it any help appreciated
Just uploaded a video that should help that definitely means it’s not getting enough fuel
I’m stalling with this carb first it just wants to take off without throttle now I’m just stalling in the street if I don’t keep giving it gas hml
So is it worth buying a nibbi carburetor
I would say you are probably better off with the mikuni knock off
@@throttlefamily4655 thanks bro you honestly always reply fast thanks
@@brayanvazquez7857 no problem also I believe I have a link to the mikuni knock of carb we use in the description I believe it’s still around $30
Would you prefer the PE series nibbi or pwk series for a 140cc?
PWK is a better carb I think nibbis are a real pain bro
Great information brotha! You guys are rockin the subs pretty fast it seems. 👍
Great video man ...I just installed the nibbi on a hawk 250 and it wont start ...I smell fuel like crazy and probably need a smaller pilot jet ...not completely sure at all but I'm trying stuff ...do jets need to be screwed in all the way.. I have no clue about that either...any info would be great
Definitely too much fuel will make your bike not run at all
And yes the jets do need to be snug
@@throttlefamily4655 I got it right finally ...my bike (2021 hawk) loves this carb ..got more speed more power starts 1st time everytime , it's good stuff ...ur videos helped alot ...thanks man ..ride on !!!
Can you do this for the Amazon carb ?
Yes I can
Ssr look small cuz the front tire is the same as the back front should be bigger better controll
The front tire is bigger than the rear
I recently replaced my carburetor to a “Mikuni” I bought off Amazon. My issue is the bike bogging in those higher RPMs. Dude you explained everything I need to know unlike other videos I’ve watched where they explain one thing, but not the other. Thank you!!
You are very welcome thank you
I got the same problem
@@throttlefamily4655 I’m referring back to this video because I’m having carb issues again. Im bogging out on top gear (4th gear) my main jet is at 125 and pilot at 38. I have no issues with idle at all. Only when I get to higher rpm the power is just crashing. I even went as low on my jets to see if it will help.. low as 88 on my main jet. I messed with the needle. Pretty much did everything. I have a new spark plug.. recently changed the oil. Anything you recommend?
Really surprised cause what worked for me before isn’t helping…
@@nicholassaldanatuning a carb can be a big pain in the but and specially when your new to it. I hade also the problem that my bike ( 2 stroke ) would not get in to its powerband. After trying idk how many jets and try a lot of different needle heights. I was slowly getting there. Some times it can take a couple evenings to get it right specially when your new to tuning carbs. Just try and try and probably you will get it right one time. Just watch out that your not running to lean so you don’t damage your engine. 😉😉 that 2 stroke was my first time tuning a carb. But afterwards if heard that ingaf a carb and air filter that where hard to tuning in and get it right 😅😅
I know he dosent care what anyone online thinks buuuut he just tuned it with the choke on 😅

U need to do plug cops at idle ,mid range and full throttle to completely tune your carb with a new plug ever time because a plug don't lose color wants it has it so if u want to take it to the next level thats your next step

my pitbike runns way too high rpm in neutral and when u ride it it feels like you ride a 80cc but its an 160cc.... what jet do i have to adjust and how much rotations.... i was told to habe the two main jets in the middle all the way in.....
No, if you're talking about the pilot jet, the one on the side of the carb, ideally you want to be around 2 turns out. Fully in should make the bike cut out if not your pilot jet is too rich and need a smaller one. If it bogs on full throttle u need to put a different size main jet, midrange is on the needle which you can adjust needle position to run richer or leaner... Your spark plug will tell you all you need to know on how your bike is running, if to rich or to lean
I just put a new exhaust on my KP MINI 2 days ago and have a nibbi carb. Its still running okay.. Its back firing every now and again when I get on the throttle. Also, Is it normal to have to kind of roll into the rev? If i go from idle and just pin the throttle my bike will bog of stall... if I give it a couple quick revs its fine and when I am out riding I can just send it.. full pinned. EDIT: as I got deeper into youre video you touched on exactly what I needed to know! Thank you! I want to go mess with my carb right now but now I am terrified of messing with that thing.
I would also like to add that your explanation on the mechanics and function is amazing
I have the knock off Mikuni which worked on my ssr 110 perfect but on my 125 I have to turn the idle screw so far out that its rattling loose so that it isn’t idling crazy high
Lower your pilot jet. I just got the carb and my bike was idling high with the Jets that came in the carb it’s a PE28mmFL stock 112 main jet 40 Pilot. I went down to a 35 Pilot and now I’m actually able to idle normal. Gotta do a couple more adjustments but other than that I’m Gucci.
Good information about your tuning carburetor thanks happy trails
What jets would you recommend for 98 feet about sea level??

Just installed my Nibbi and set it at the baseline setting you used. Idles good with choke off but its cutting off over half throttle blip.
Haven't changed the jets yet, would I be running too lean or too rich? Just unsure where to start with changing jets, and which ones needed to change.

I just ordered a pwk 28mm for my 1977 Yamaha dt100. It is supposed to come with the right jets and screws. I see a lot of confusing info that this carb doesnt work with a 2 stroke. Are people saying that the two stroke oil reservoir cannot be hooked up to the carburetor? If thats the case, do you just mix the 2 stroke oil straight into the gas tank instead? Or are people just posting bad information. This seems to be hard to figure out how everything gets swapped out and adjusted. This video helped with a lit though, thanks.
Hey, can you send me the link for the adapter? My Amazon Knockoff carb is sadly junked, looking to buy a Nibbi 24mm for my 2019 Apollo 125cc X-18. I would go with a genuine mikuni but god I HATE how the tuning screw is on the bottom. So going with the Nibbi. But yeah if you could send the adapter link i would applrexite it

If you're gonna give hundreds of people advice...you should REALLY work on your terminology.
You're calling tabs and clips, pins...you're calling grooves, rivets...you're calling the idle screw, the fuel screw...you're saying press down instead of bend. I heard SEVERAL things that are totally incorrect terminology.
You've got the mechanics and operation of a carburetor DOWN PAT!! Seriously my dude, YOU KNOW YOUR SHIT...but your terminology is WAYYYY OFF. It could EASILY confuse a newbie that is trying to tune his/her bike. I think you just need to slow down and think about what you're saying. It just seems like you're getting in a hurry and spitting stuff out.
