How about the power jettings explained, and how it works?
Didn’t even mention the power jet and adjustment screw.
Where do you install the vacuum for the fuel cock?
What is better? pwk or pe?
Hello! I've bought PE26 for my yamaha DT125 and jetted it to 30/135. It runs good, but when I set the air/fuel ratio it is either very stong on low RPM and weak on high RPM when I give it more air, or strong on high RPM and weak on low when I give it more fuel. Any ideas what should I do? Maybe a diffirent carb like PE28 or PWK26?
Use 30/120.
Has anyone used nibbi on outboard motors?
dp you sell the pwk jet kits? i see just pe and the pwn jets

Can any Carb gurus help me answer a question? Recently, when I turn on the gas valve on my bike, fuel constantly flows out of the overflow and flows out of the intake. I believe its a problem with the float but haven’t had the time to take it apart and mess with it yet. It used to do that sometimes and shaking the bike would fix it. Now the ole shake method doesnt work and its constantly dumping fuel. Any tips or suggestions on what It could be?
Hi, please check if there is anything blocking the needle valve. We suggest taking and float chamber off for cleaning to see if it overflows again. I hope this helps, thanks! :)
@@nibbiracingusa turns out gas was seeping into one side of the float. took it apart and half the float was filled with gas. I'm pretty sure that doesn't happen very often. kinda crazy!
Hi i have NC 450 engine on my 2021 Kews 450 so can you tell me which nibbi carb i need for it?
Hi friend, contact us via email plz: help@nibbiracing.com
Hi ! Where can we found the powerjet setting ?
Hi there, thanks for your interest! More info about this Nibbi PWK carbs will be released soon, stay tuned!! :)
How do you tune it and where do all
Those extra hoses go my PE nibbi 22 doesn’t have all those hoses
Hi MJ, any questions about installation and tuning, feel free to shoot us emails at help@nibbiracing.com!😊
Bought a bike with a nibbi carb. Is there a way to identify if Its a PWK or PE?
Yes! They're different in the throttle valve. The Nibbi PE carbs have a round slide design, while the PWK carbs have a semi-flat (D) throttle valve. I hope this helps, thanks. :)
Non riesco ad aprire la vaschetta come faccio
Think I could get a 38mm to work on a drz 400e?
Yes, I believe the PWK38 could be compatible with the 400cc 4-stroke engine. Kindly head to the site to learn more about the specifications of the carb. I hope this helps, thanks! :)
Whne connecting the carb to the bike with the boot do u need a o-ring? I have a pwk 24mm hooked up to my predator 212 and i cant seem to get it to run correct. The carb be cold to the touch after it euns for a while and once the bike starts it bogs when i give it gas and almost shuts off during take off. I need help
Hi there, thanks for getting in touch and we're sorry for this issue. To get Nibbi carbs to fit on your Predator 212, you may need the specific manifold, and for the model of carb, we'd like to recommend the PE24FL/PE26FL carb. I hope this helps, thanks!! :)
I just wanna know if the pwk carbs come tuned from factory?
Yes, tuned for general, and also jetting needed when installing on your bike.
Need adjust for your bike manual
Allways check your purchased engine parts. Manufacturers supply a standard setting in all means. I upgraded my little 50cc two stroke to 74cc. Admission and Exhaust timings were not so good, transfers not fully open, piston ring gap too small and compression Ratio very high maintaining a reasonable squish. So, talking back about Carburators, it´s very important start with rich and go back step by step because lean kills the engine. So in my case, because of a high compress burning, i go with higher Octane and i mix 20% Ethanol. For that i need special bigger jets. Ethanol does not need more air then gasoline, it transfers Oxygen molekules. So, no bigger carburator diameter is needed, only bigger jetting. Just allways check what you got supplied and the settings for your needs. Cheers dude.
@@danijuggernaut yes my pwk carb was way off I returned it cuz I couldn’t tune it and I got the round slide carb with much better results
There is a difference in the 2 stroke and 4 stroke version. What about this carb???
Hi, the Nibbi PWK carbs could fit on a 2/4 stoke bike, and perform well for 2-stoke. I hope this helps, thanks! :)
@@nibbiracingusa what would be the proper size PWK on a genuine Buddy 125 cc two stroke scooter?
@@louisalcaide5885 Hi, could you please provide the stock carb spec, please? :)
NONE
This is not tuning.......what is the high speed oiling device for?
Do you refer to the power jet on the PWK?
I don’t want oil in my carb….Just saying
I saw that too, might be problematic
Translation issue, lots of Chinese carbs say oil instead
I mean if it's a 2stroke then yes but not a lot lol
what size was the hex driver
Hi, it's 3mm. :)
@@nibbiracingusa thx
hello i was wondering if a pwk 28mm would work on my yamaha blaster as ive heard good things about nibbi carbs and would like to use one my build
Is there a 24mm intake?
Yes! Here is the link for the 24mm, I hope it helps. Thanks again for your interest! :)

@NIBBI Racing I should have been more specific. An intake manifold not the carb. Was thinking of getting the carb but can't find an intake manifold that would fit.
@@facepalm015 Hi, the outer diameter of the intake side for this PWK24 carb is 35mm, you can get the manifold in this size. I hope this helps, thanks again! :)
Is this carburettor will fit with honda cb250 1993 ?
Hi there, is the stock engine of your CB250 bike a parallel twin one? If so, you may need to confirm with the manufacturer if it needs to be modified since this carb can fit on most single-cylinder engines, not the twin. I hope this helps, thanks again! :)
Will a 38mm nibbi pwk work on my 1991 Yamaha wr250z? What size jets come in the carb?
Guys… I get it. You have to outsource your manufacturing in China. That’s the way of the world now. But the robot narration? Really? You don’t have anyone stateside to read this? Or at least edit it?
Gotta love how they mis label the "choke" too
It's an enrichment circuit (allows more fuel in, instead of choking off air)
How to install and tune I don't see anything about tuning
More videoes about tuning will come soon, please stay tuned!
Hell I don’t see anything about installing. Can’t figure out where the throttle cable attaches to the needle slide.
DROP THE RUBBER GLOVES @@nibbiracingusa
Connect the hose to "it"... WTF was IT?
Power jet, they suck at explaining. When theres enough vacuum from full throttle fuel will get sucked up the hose going down the jet mixing with the air rushing into the carb. This means better atomisation and higher fuel content in the chamber plus more air so engine makes more power
Oil Level...? 😂
Why the fuck is this taken apart
You mean gas intake not oil
