Installing Extended Air Fuel Screw Mikuni VM22 and PZ30

[@jamesa6272]

Thanks for making us go deaf with the beginning of your video.

[@isaacgonzalez9295]

Dumbest place for a air fuel mixture screw🙄. Always have to take mine off to tune it

[@jerolehmuskoski5108]

same here...

[@skullcam]

AWESOME....NEVA SEEN THAT MOD BEFORE

[@jamesjohnson9833]

Amazing mechanic advice this dude is gold

[@yellowdemon16vt74]

You can get fuel screw at any dirt bike shop or online

[@poolman8201]

Why do you use the old spring and not the one that comes with it ?

[@roadgaper2570]

I'm going to try one of those but what I'm really looking for is an extended IDLE SCREW for my VM26 clone

[@ebkbk9902]

did it end up working i have a vm22 and they say theres no extended screws available but they make them for the vm26 which uses the same screw as a vm22?

[@roadgaper2570]

@@ebkbk9902 Oh man I got rid of that vm26 clone a long time ago and got a Nibbi PE30 and never looked back

[@roadgaper2570]

@@ebkbk9902 I never did find the right size screw for the vm26 though. Anyway trust me get a Nibbi PE30 OR a Nibbi PE28 and you will never mess with the VM's again

[@nickcr8]

Where did you buy this extended screw for a vm22 carb every where i look i can only find them for the vm26 or higher carb

[@nickcr8]

To everyone that is out there and is struggling to find one of these extended screw. i did my research and i found out that the vm22 carb and the vm26 carb both have the same size hole and thread size for the Air mixture screw so the ones on ebay that state there for a vm26 carb will fit in your vm22 carb. to be honest those these mkuni carbs are cheap and fake your better off buying a genuine mikuni Carb

[@stampydragon2739]

@@nickcr8 actually the vm 22 carb isn’t fake there made by Mikuni and they have been since the 1980s as they were used on the dr series of bikes there is just so much suply that a lot of Chinese motorcycle manufacturers use them as there cheap as hell due to the shear number that have been produced

[@danielkerr4100]

@@stampydragon2739 these carbs are fake tho they're made in china the legit mikunis say made in Japan the fake ones just say Japan also the legit mikunis have an idle screw you adjust by hand

[@warrenpeas]

@@nickcr8 did you try one? it might fit but the needle tip might be too different?

[@whiskeythrottle8680]

Just switched from the sock jet to a 115 now it has all kinds of throttle up high but just need to adjust it down low is bogging

[@grayghost832]

Okay so my pz30 on my hawk 250 had the mixture screw turned way out and it wouldn't run without choke. So I turned it in so it was only like 1 and a half out instead of 2 and a quarter. It will run without choke now so that tells me in is more of a rich mixture.

[@leecasteel9211]

I got a pz27. so your saying tighting the screw makes it richer? And loosening it makes it leaner?

[@grayghost832]

@@leecasteel9211 yes loosening it opens it up more inside and allows more fuel to pass through. Also if it starts popping bad you know it's too lean.

[@leecasteel9211]

@@grayghost832 oh okay thanks yeah my problem is when i try to snap the throttle from idle to wide open it bogs down and if i just hold it it'll die..but if i kinda just roll the throttle smooth it's perfect..my guess would be its too lean might have to get a bigger slow jet i tried adjusting that screw and it didn't do much.

[@grayghost832]

@@leecasteel9211 Yeah that might be your issue. There's the main jet and the pilot jet or whatever they call it and I just got some cheap ones off eBay. It will do some funky stuff if like that if it's not quite getting enough fuel at lower rpms.

[@danielkerr4100]

@@leecasteel9211 no if its only when full throttle then it means its too rich you need to make it slightly more lean

[@Maxumized]

These replacement screws are not the same. Notice the needle differences. The original is longer. The replacement has a totally different adjustment characteristic...beware

[@madfisherisme]

Hmm I been looking everywhere for a fuel screw for my pz30

[@stampydragon2739]

can you also swap the throttle side adjuster on the vm22 for the one on the vm26 and can you give me a link to part for vm 22

[@_mirooracing_]

i have xmotos 250cc XB-88 and i cant find normal.. carb mixture i have about 1/5 and bike start i warm it but its not rev full throttle? i hear booooo

[@alanhadley9848]

So will this fit a Vm22 26mm mikuni carburetor because I can only find ones for a Vm26 30mm carburetor. I have also been told by someone who sells carburetors online that the Vm26 carburetor mixture screw has a thread size of M6x.75 and the Vm22 is M6x.5 I'm a little lost can't seem to find the one I need and no one I ask can tell me if it fits the carb

[@alanhadley9848]

@the jealous gonad thanks for letting me know I ended up using a small screwdriver piece with some electrical tape wrapped around it done the job just fine

[@818westend7]

Wait so which one is it I have the same problem with it being a Chinese carb n jets are the wrong size

[@daneger21]

If you look close, the tip of the extended screw does NOT match the original air screw tip. Will this matter?

[@Kornatzz]

You should be fine

[@Maxumized]

It does matter. I can only turn out mine 1/4 turn for maximum idle. I don’t want to hear that my pilot jet is the problem. I’m running a 20 pilot jet at 800ft elevation...pilot jet is not the problem

[@danielkerr4100]

@@Maxumized it doesnt matter at all

[@petert696]

where can I buy one of these extender screws please?

[@SoloArtForm]

try aliexpress

[@Kornatzz]

amazon

[@4687878]

I thought the tighter was more fuel ? Counterclockwise is more air (leaner) !!

[@joelmayores307]

that is for air-fuel screw principle, the fuel-air screw is the opposite...

[@bugzbunny3223]

Depends on carb design

[@bugzbunny3223]

Some have fuel screw, which would be on the front of the carb, some have a air screw which would be on rear of the carb

[@bugzbunny3223]

Air screw adds more air as u loosen it, fuel screw adds more fuel as you loosen it

[@paulodwyer8626]

link for the extended mixer screw please.

[@mikeherzog8878]

Amazon sells them. I believe you have the o-ring and washers on wrong. They go below the spring don’t they?

[@dowser81]

no the o ring creates the seal so goes on last after the washer

[@danielkerr4100]

lmfao why would the o ring go after the spring

[@waseemullah07]

[@bernardmt7090]

This chinese mikuni vm very problematic to tune. As last I installed an Original Honda Keihin carburetor and its so easy to tune and been running the Keihin for 2 yrs now without any problem.

[@Revdonlee74]

I went to the website, what is the part called to enter in the site search?

I have a pitster pro x5 pitbike with a yx150 motor on it.. im having issues i got the bike running good and idleing fine.. now while im holding the clutch in and put it in 1st gear it jumps and instantly dies as if im not even pulling the clutch handle in put i am as far as it will go and still has this issue.. starts up fine in neutral till i put it into gear.. also online says its a start in any gear and in 1st gear with clutch pulled it jumps when kicked over as if clutch isnt working and its sitting just sitting in gear with no clutch used .. any ideas ??

[@phillipj4831]

Jeff Vanderwal adjust your clutch

[@stricknine8623]

It's probably a "wet clutch" ......They depend heavily on the correct oil viscosity if it is a wet clutch.

[@cruiserdonrussell4799]

can't be too smart calling the idle mixture screw assembly a " jet" ! 1D10T

[@rodneyws1977]

No reason to be mean like that. It's just an adjustment screw. I just got my first VM22 and this looks like a great addition.

[@Khantagious007]

Just curious why your here watching this video?

[@afkgang5076]

Could this cause high idle

[@jokezpaine3408]

Is that the Chinese vm22? Cuz mine doesn't look like that at all.

Yes it is,..I have the same copy,..and it bogs all day !!! I'm going for the genuine vm22 133

ur toast

yikes man grey is not good

a light tan/gray color tells you that the spark plug is operating at optimum temperature and that the engine is in good condition.

Isnt this the air screw?

[@Kornatzz]

yeah air fuel mixture

[@charlesgunzelman3323]

@@Kornatzz No it's a fuel screw for adjusting air/fuel mixture at idle. If it was on the airbox side of the carb, it would be an air screw. Most 2 stroke carbs use an air screw, except for Dellorto carbs, I've only seen them with a fuel screw on 2 stroke bikes.
