Thanks for this. I just got a new exhaust, went with the Stoneman, I'll probably switch to a 120 main 38 pilot. I'm in Southern Michigan around 9000 if I remember correctly. This video saves me time since I don't know carbs all that well.
Hey , great demo and info on how it works ...u nailed it ....I just installed a nibbi on my hawk 250 ...the bike flys now , its got power and top end , I'm loving it...pz30 is a super basic carburetor...its junk in my opinion...great video buddy ...keep em coming
Happy to help brother! I absolutely love nibbi carbs personally I find them impossible to beat for the money 4 for 4 with them so far as they all run great!
@@Jboost412 agreed!!! Nibbi cant be beat for the price and performance...its an amazing product ..but get this, the nibbi cone filter didnt fit the intake on the nibbi carb when I installed it ...strange right?? ...so had to bore out the rubber boot a little to get it to fit ..
Really?!? That is strange…for the 30mm or the 28mm nibbi we all run the nibbi 48mm it fits perfect in wondering if you got the right box but incorrect filter inside…but yeah that’s all just bore it out a little and you know you have a tight seal! Don’t forget to pick up some filter cleaner & oil personally I use maxima cleaner & oil as it really does a great job of cleaning then the oil isn’t runny plus it’s a distinct greenish blue color so you can see the oil is distributed across the filter evenly since k&n oil is runny for one but it’s also red and tends to lay on too thick affecting your air/fuel mix
@@Jboost412 so yeh after using a heat gun to make the rubber more pliable on the cone filter but it wasnt enough so after boring it out I was afraid little rubber chunks would get in the carb but I blew it out with compressed air and seems to be fine ...its day 5 running it and like I said , the bike moves now ..i can get the front wheel off the ground out of 1st real easy now ...so ur saying i should oil the cone filter?? ( I'm new to this obviously..lol 1st time ever doing a motorcycle carb swap ) ...what's the purpose in oiling it ..wouldnt sediment get stuck to it ...I Seriously never heard of oiling a filter . I just take it off after a trail ride and blow it out with compressed air ...but lmk I'd I'm doing something wrong ...your info and knowledge is greatly appreciated bro ...ty again and if you've checked out my videos , please critique...lol
Yeah it’s just something you do to the filter to aid in keeping out I guess we will call them micro particles that could otherwise potentially pass thru the filter so you just clean it up real good if it’s already been used and coat the entire filter part with the filter oil I clean and oil mine about every 4-5 weeks it’s always filthy on the outside but my carb & inside of the filter are always spotless I typically ride in really harsh dirty terrain so my filter probably gets allot dirtier then someone who rides on the street or in less rugged terrain but once you start running the pod filter like you are you’ll see when it’s at the point it need a good cleaning & oiling again for now blowing it out with compressed air is definitely what you wanna do to make sure it stays as clean as possible
Hello great video, you make it look simple. i know its been a year but can you please point me in the right combination of jets. I have the 28mm nibbi carb for my hawk 250 and i want to do the 300cc (70mm) big bore kit, will a 38 pilot and a 120 main give me the right amount of power, I want the bike to run at its full potential with these mods and not fall short. I live in Miami Im pretty sure we are below sea level (always getting flooded, lol)....thank you for your help
Hello, i live in a place where elevation ranges from 2,700 - 3,500 feet. I want to get a 28mm nibbi for my hawk 250 and rejet it properly. I want to remove the catalytic converter and get a new intake. What size jets would you recommend? Thanks!
Well jetting I would say start with a clean spark plug and go with a 115 main & a 36 pilot adjust the air/fuel screw for your pilot circuit around 1 1/2 turns out from all the way in and that should be about right for you…but ride it for a day and then check the spark plug to make sure! Don’t hesitate to ask any questions that’s why I’m here!
Instead of removing the cat itself for 89.99 i highly recommend the jfg exhaust system I have a video on the install basically a direct bolt on fit and there’s links in every video I have so everyone gets the right parts
Absolutely anytime! Always happy to help! I try my best to make sure everyone gets accurate information about these bikes since there’s allot of bad info out for them that can potentially mess up your bike pretty quickly!! I’m also on Facebook I run one of the largest groups for China bikes it’s called the chonda riders if you wanna stop by you’ll find allot of info about things I’m developing for them like big bore kits etc etc
I recently purchased a 2004 Yamaha 125 TTR and then purchased a 125CC 26 mm Nibbi carburetor for it. My problem is I don't know how to jet it or adjust the needle. And the moment it does turn over it will not idle and just shuts right off. Does anybody have any suggestions for me?
Carburetor size is correct for a 125 I believe off hand your main jet should be a 105-110 and the pilots probably something like a 32 air fuel mixture set between 1 1/2 turns out to 2 turns from lightly seated in hope that gets you running!
Just ditch the clone carb buy a Nibbi pe28 FL version it’s a direct bolt in carb no intake change no need for a new filter just use the jets you already bought and go!
Best video for helping us rookies!!! Thanks a lot. wish I would have watched before installing my nibbi pe28fl. Now I have to uninstall and reinstall lol
I have a TBR7 on order and plan on upgrading the carb to the Jfg pz30. Elevation where I am is 344 feet above sea level. Should the carb be ok out of the box, or should I go ahead and order jet kit? Or should I just try it and see how it does before re-jetting?
I genuinely don’t know what nets come in them but in my carb video you’ll find a jet kit that’s perfect as far as jetting a stock bike at that elevation a good place to starts around a 105-110 main and a 34 for your pilot reading the spark plug for fine tuning as black will be rich whites lean and you wanna see a brown-tan Color for optimal performance…also make sure you watch the valve adjustment video you’ll have to do that immediately! They come ridiculously tight out of the crate
Working on a whole new build brother! I blew the seals on my quarter windows so I had some water leaks to address so now I’m going b pillar walled to beat my 155 at 39hz! Had to be water tight first though 😂
Amazing video thank you Jay. I have a question, running an ace 250 with a pz30 pumper carb. I range from sea level to about 600 ft. I cut the muffler off and replaced with a stubby slip on. Bike came with the cheap metal pod filter already. I’m thinking 38 idle 120 main? Does that sound about right? Thank you I appreciate your time.
With the cheaper clone carbs there’s not really any different taper needle jets now for the genuine Mikuni vm26 yeah there’s different tapers you can try…the main jet being stuck just hold the emulation tube with a wrench I think 1/4” off hand and it should crack loose if you grab the jet with a screwdriver if not you’ll just need to replace it with another Amazon eBay carb they’re hit or miss sometimes but I don’t recommend them anyway as they’re called a 30mm carb but it’s really a 25mm carb acting like a bottle neck for the air & fuel
You may already require more fuel then a 110 can provide depends on some factors elevation being one of them my bike needed a 115 bone stock right out of the crate ask Google what your elevation currently is
Great video on the parts and explaining what/how they work! I am currently mounting a Honda gx240 (240cc big block 8hp) that has low hours on it, i'm putting it on a circle track Go kart I got from a good friend, I Want too change out the stock carb for a nibbi or Mikuni/clone, what size carb should I go with? Would a 34mm be OK or too big? And some starting jet settings? Thank you!
On the nibbi intake you have a link too says 60mm from bolt to bolt did you use it with the factory intake or how did you get it to work,my intake holes are about 33 mm? I'm looking for a new intake,and just want too get the right one ,, thank you
You remove the janky stock style carb & intake completely off the bike and then the new nibbi intake bolts directly to your head then the carb slips into the coupler that goes from the carb to the intake with 2 clamps it’s been the best intake I’ve used.:.and I bought every single version possible to see what works best
Sorry to keep bothering you. But I did the valves this morning 004 on exhaust and 003 on intake 115 main still only 53. 55 mph wth!! And with the 45 rear sprocket. Fyi the valve's were tight as shit! 🙄 I'm at a loss
Just to make sure recheck them again on a cold engine to verify you did it on the compression stroke & tdc happens often enough they get adjusted on the wrong stroke or possibly they’re a hair looser then you want anything.002-.003 is fine i like .004 on my exhaust because of the head work I do on these bikes we’ll head work big bore kits cams you name it I make it 😆
@@Jboost412 looks like my cat is plugged until I get my pipe I'll cut it open tomorrow at work and weld it back together. Thanks for all your help. I'll keep you posted on the progress
@@Jboost412 ok so I didn't tell ya before but the jets Amazon sent were for a Mikuni so I had to file the threads almost off lol but they went in tight. I got the cat out today and it was stumbling at wot. So I raised the needle jet and it seemed better but still only 50?? I'm gonna order a nibbi carb and set the valves at 002 and hope for the best.. thanks again Rob.
@@Jboost412 lol🤣 great news the damn throttle cable was keeping it from wot . It was a new one and I cut the casing back but not the spring metal on the cable I now have real wot👍🏻👍🏻👍🏻👍🏻
Hey bro I just got my jet kit in today for my pz30 pumper carb and need some recommendations on jet sizes to run I'm at 15 ft elevation(5m) currently has a 115 main and a random pilot jet with no markings. I just put full exhaust system on recently
Best video on carburetor jets I have seen yet , one question one the nibbi ,you said start with 2 turns out on fuel screw, which I believe is brass screw,, how many turns out is a good starting point on the idle knob? Thanks again
Happy I could help! Yeah 2 turns on the air/fuel is a good place to start your idle really varies typically ends up being set more then once with the bike cold then warm again
@@Jboost412 yes I understand that i have to adjust the knob after the bike warms up too get a good idle,but unfortunately I turned it all the way out too the point it will come out, and I'm trying to find a good starting point with it,, all the way in? All the way out? In the middle? Lol I should have payed more attention,but now my bike will not start,,hopefully that explains my ignorance of carburetor a little better lol
No worries typically threaded in around halfway is a good starting point I honestly don’t remember how many times that is roughly 5 but I could completely wrong there
@@Jboost412 thanx man ...my elevation is 765 ft according to google ..my nibbi came with a 40 in it and extra 38 pilot...I put the 38 in it instead and it had a 128 main in but I used a 120 instead ...seems to like it ..just wondering if I should change them out.. just trying to get the best performance from it ..and thanx again jay ..
So the jetting your running currently is pretty well right on as a safe baseline for fine tuning at that elevation….best thing to do from here would be pop your spark plug out clean it with a wire brush so it’s fresh & shiny ignore whatever soot or what not is currently on there as it’s gonna be from previous runs after a day of riding pull the plug again let me know what she looks like…but as a quick reference blacks rich whites lean & optimal will be a brown sorta tan color you’ll probably find it to be a little blackened for the first few tries at 100% fine tuning it but it’s always safer to start rich and dial back then it is to start lean trying to work your way up…just in case someone else reads this please never start lean! You might cook the motor before you find “your” optimal range
Hey man great video. I’ve got an Apollo 250 just got a pz30 for it and the jets your recommended. Just looking for a recommendation to start at. I’m at 745ft above sea level. I started at a 45 and 120 off someone else’s recommendation but the bike it way to rich at idol. Spark plug was black and wet after running for 5mins. Any advice is appreciated
Absolutely no problem at all…and yeah that’s way too much on the idle circuit I don’t know how anyone could recommend that jetting to a fellow chonda rider and sleep at night 🤦♂️ factory exhaust do you have a pod filter or anything like that?
And thank you I highly appreciate it!! Trying to build a chonda off UA-cam making sure your getting the correct information can be tough since people love sharing the wrong info 🤣 so I’m happy to see its all working out finally made it to 1,000 subscribers if you haven’t already & don’t mind hitting the like & subscribe button I highly appreciate everyone’s support!!
Thanks for the reply. Yeah man it’s been impossible to get good information. Hours spent researching and getting no where. Everything on the bike is stock and no problem liked and subscribed.
Highly appreciate the support!! So a otherwise stock bike at roughly 750ft ASL you’d be right around a 115/120 main & a 36 for the pilot jet with your air fuel mixture set about 1.5 turns out from lightly seated in with your needle jet in the center position for now!! Gone that a go & let me know what you think!! I’ve tuned so many of these engines with doing the performance work we do here big bore kits high flow ported / decked heads cams etc etc that while jetting is definitely no one size fits all I always have a good idea of where to start out!! Also clean your spark plug up with a wire brush or something mildly abrasive so you have A good clean spark & B no overlapping results from the prior jetting!!
Yeah that’s why I started making UA-cam videos & founded the group on Facebook the chonda riders…way too much false information about how these bikes run it how to set them up what things actually need done & how to do them it’s enough to make your head spin 🤦♂️ so always trying to make sure it’s easier to get the correct information about how to do something
Yo I need help my 2017 hawk has 800 miles on it I put a 110 jet in it and a 45 tooth rear sprocket with the stock 15 front waiting for the 17 tooth. But it still only goes 53 max mph??? At this point I'd be happy to get 60
Adjust your valve lash correctly on a cold engine and why a 110? That could be right or completely wrong the jetting gets picked by your elevation I see allot of people go with a 110 because a UA-cam said it was right but it’s usually not so shoot me your elevation so I can see how close that is to being correct
Good explanation 👏 I was wondering if you had any recommendations as I've been having a hard time getting mine dialed in. I've got a 2020 recon, racing cdi, Keihin 30mm carb, nibbi coil, and aftermarket exhaust. I'm at about 500ft elevation. Currently have it set at 35p and 125m with needle set at 4th down. I feel like I've bounced back and forth 100 times now with no luck. I would appreciate any insite
With the bigger ignition coil because there’s more spark now open the plug gap up to .035 versus the factory recommended .028…and what air filter are you using as the China Nibbi filters really restrict air flow so I find the genuine k&n filters helped allot with what i thought was a jetting issue with my bike had me chasing my tail
Got ya! Yeah I would start there as I had a similar issue..:.the k&n that I know for sure fits is in my video about a keihin pwk carb review down in the video description you’ll find a genuine k&n to ditch the China filter
Absolutely no problem at all! If you have any issues setting up your carb let me know I can give you a general idea of where your jetting should be with some info like your rough elevation and what you’ve done to the motor so far!
@@Jboost412 at 1.5 turns of carburetor of honda cg125, plug colour is white at tip but black at circular side. I have installed new plug so this problem is occurring while in old plug there was no plug like that.

I’ve tuned so many of these engines with doing the performance work we do here big bore kits high flow ported / decked heads cams etc etc that while jetting is definitely no one size fits all I always have a good idea of where to start out!! Also clean your spark plug up with a wire brush or something mildly abrasive so you have A good clean spark & B no overlapping results from the prior jetting!!
Yeah that’s why I started making UA-cam videos & founded the group on Facebook the chonda riders…way too much false information about how these bikes run it how to set them up what things actually need done & how to do them it’s enough to make your head spin 🤦♂️ so always trying to make sure it’s easier to get the correct information about how to do something
Yo I need help my 2017 hawk has 800 miles on it I put a 110 jet in it and a 45 tooth rear sprocket with the stock 15 front waiting for the 17 tooth. But it still only goes 53 max mph??? At this point I'd be happy to get 60
Adjust your valve lash correctly on a cold engine and why a 110? That could be right or completely wrong the jetting gets picked by your elevation I see allot of people go with a 110 because a UA-cam said it was right but it’s usually not so shoot me your elevation so I can see how close that is to being correct
But overall I’ll happily get you there!
@@Jboost412 so awesome dude. I'm in Minnesota. And yes I seen alot putting 110 jets in lol so I tried if the stock 98 almost seemed good?
Ask Google what your elevation is currently for me
@@Jboost412 1200 feet above sea level
Good explanation 👏 I was wondering if you had any recommendations as I've been having a hard time getting mine dialed in. I've got a 2020 recon, racing cdi, Keihin 30mm carb, nibbi coil, and aftermarket exhaust. I'm at about 500ft elevation. Currently have it set at 35p and 125m with needle set at 4th down. I feel like I've bounced back and forth 100 times now with no luck. I would appreciate any insite
With the bigger ignition coil because there’s more spark now open the plug gap up to .035 versus the factory recommended .028…and what air filter are you using as the China Nibbi filters really restrict air flow so I find the genuine k&n filters helped allot with what i thought was a jetting issue with my bike had me chasing my tail
@@Jboost412 its the nibbi air filter. If that's the case, I may have to find a k&n.
@@Jboost412 although it still isn't running right with the air filter off
@@Jboost412 I'll try gapping the spark plug real quick and see if that helps
Got ya! Yeah I would start there as I had a similar issue..:.the k&n that I know for sure fits is in my video about a keihin pwk carb review down in the video description you’ll find a genuine k&n to ditch the China filter
Any idea what size thread on main jets on 24mm nibbi
Off hand I don’t know but I can definitely check in the morning with my tap & die set and let you know what I find
@@Jboost412 yes sir thank you
Absolutely!
Looks to be a M4 style thread from what I’ve gathered hope that helps! What did you need the size for I’m curious?
@@Jboost412 100 was the smallest main jet that came with this 24mm nibbi I think it's just to big
bro? mikuni carbs are different from keihin. the only way they are similar is that they are both carbs. they are to be tuned uniquely.
An actual legit Mikuni absolutely these clone carbs no there’s no difference
@@Jboost412 yah I agree with that i should have been more specific lol
merci
Mixture screw setting
For best setting, how many turns from fully closed position
You always want to be around 1.5 to 2 turns but that requires you to have a correctly sized pilot jet
@@Jboost412 Thank you so much
Absolutely no problem at all! If you have any issues setting up your carb let me know I can give you a general idea of where your jetting should be with some info like your rough elevation and what you’ve done to the motor so far!
@@Jboost412 at 1.5 turns of carburetor of honda cg125, plug colour is white at tip but black at circular side.
I have installed new plug so this problem is occurring while in old plug there was no plug like that.
Please let me know that after what period new plug is inspected.
I installed new plug in the morning and checked in the evening.
