HOW TO Install & Tune a Nibbi PWK Carburetor (step by step guided!!) 

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

Use 30/120.

Yes! Please check the shop links below to get the both main and pilot jets kit for your Nibbi PWK carb.

Hi friend, contact us via email plz: help@nibbiracing.com

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 there, thanks for your interest! More info about this Nibbi PWK carbs will be released soon, stay tuned!! :)

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. :)

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! :)

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

Gotta love how they mis label the "choke" too It's an enrichment circuit (allows more fuel in, instead of choking off air)

Man I a rolling wrench pwk. 175$. It's on a qmb 39 with bigger head an piston

Hi MJ, any questions about installation and tuning, feel free to shoot us emails at help@nibbiracing.com!😊

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!! :)

yep thats what my pwk does on my predator 212, every damn time its high idle on choke then dies off choke. but the pe runs fine. whats up with this? i swear these pwks dont work on 4 stroke predators.. dont know how anyone runs em

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

Do you refer to the power jet on the PWK?

Hi, it's 3mm. :)

@@nibbiracingusa thx

Yes! Here is the link for the 24mm, I hope it helps. Thanks again for your interest! :) The Nibbi PWK24 Carburetor: nibbiracing.com/products/pwk-carburetor?variant=42278397051045

@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! :)

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! :)

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.

​@@nibbiracingusawhat is the proper way to tune the air/fuel screw

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
