Wow what a great video Black66! Keep those videos coming out please.
I hope everybody appreciates how much money and effort you save them with these videos, I sure do! Big THANKS C.O. 💪
Thanks!
This video just taught me what I needed to know to get my bike running again. I was so close to taking it to get tuned somewhere but thankfully I saved money because you showed me how to do it myself 🔥🙌
Man u are a God send I don't see y this video doesn't have more likes! This doesn't just work with minibikes but also with any carbureted bike! Thank u.
The only people I respect who build mini bikes. Are black66, and royalJz. Nobody else. They are the mini bike kings. Keep up the work 66 I love the content
Whos royaljz 😂
@@oswaldocastillo6305 TH-cam it.
Surprise minibike expert didn't pop out 🤔
Thanks for this, Ive been struggling to get my Suzuki king quad to run right. Using OEM jets and just did a carb rebuild. Finally opened up the throttle setting for max richness and she runs great
Best videos for mini bikes by far👍
Must’ve watched 100 videos of yours by now
Thanks! Thanks for watching the videos!
needed a video like this haha just dialing in the tuning on my 22mm mini this really helped out!!
We do it opposite here. We don't turn down the idle screw. Over here we either turn up high idle on the idle screw, then tune to the air/fuel screw to it's highest sound.
Or u can just turn the throttle up and hold it and adjust the air/fuel mixture screw to it's optimal.
Every mechanic in the shop does this too.
It's fun doing things differently. Check out the other carb-tuning videos on the channel. Thanks for watching!
ive been o2 tuning all my carbs gives me a really good range
Another great how to!!
Great video. I share the heck outta the Vm22 one... I'd also mention make sure there are no intake manifold leaks or all your tuning won't react well.
Thanks! Yes good point!
Quick question sir someone was asking you a question about this carburetor and you referred them to watch the build video but this video is a 24 mm carburetor. The one on your build is a 28 mm so why did you switch out from the 28 mm to the 24 on this video? Was the black carburetor u did with the original video is something wrong with that one vs this one ?
Really like these tuning videos it helps a lot with understanding these carbs better keep up the great work 👍
Also question, what carburetor size do you recommend to sue with a 272 cam? I haves a stage 2 predator that had a cl1 cam and vm22 carburetor ran good. Swapped in the 272 cam and now its an absolute pain to start and spits flames out the exhaust. Adjusted valves and everything.
Just got my pwk 28mm in. Going to follow this video for tuning
where did you get your pwk 28mm from?
@@kevinzarate5681 I got it off Amazon as a kit, came with intake, filter and Jets
Great video 👍 I have 4 of these carburetors on mini bikes and they can be a little tricky sometimes. The one I am trying to tune now seems to work fine except when I tip the bike over on the kickstand it sounds like it's flooding out and sometimes dies. Float to high maybe?
Can you make. Video on how to make a header pipe for the Doodlebug stock
I was wondering if you would do a video on different types of mufflers. See if any help performance as opposed to hurting performance.
SOMEBODY GIVE THIS MAN A TROPHY 🏆
This is a really nice carb kit for only 33 bucks! I just saw your review on Amazon of it Mr. Black!
Question: I have a genuine tm-24 that I’m about to put on a Tilly 212 going on a full size rascal, and I would like to purchase a jet kit for it. I’m in south Louisiana where the elevation is -8 to +30. Could you tell me where I could get a good jet kit for this and the range I should get for my elevation/ area?
Can you tune a stock or mod 212 carb? loved to see it.
I have same carb and wen I had it all the way it blogs a Lil then it goes I got 110 jet u think I need a 115 and my needle is at the top slot
Need help. Live in Houston Texas. Still can’t get this pwk 28mm right. It is an absolute pain in the ass to start. Once it’s running it runs pretty good other then some hesitation when you go WOT but for now I want to get it to start properly. Predator 212, billet rod, flywheel, 26lbs springs and 272 mongoose cam. I tried watching both your tuning videos but I can’t get it right. Engine ran good before with vm22 and CL1 cam. This issue started with the install of the 272.
What about the "power jet" on that carb? I'm trying my first pwk and that's new to me.
Do you have to advance the timing 8 degrees in order to upgrade the carburetor and it run efficiently im getting muddy trottle at 3/4 so i thought needle but after some research was told i needed to advance my timing to 32 degrees with a 8 degree keyway or a aftermarket flywheel with 8 degree advance built in does this sound correct to you
I needed this video. My pilot is too lean
do you know what size pilot and main jet i should run? i live in florida
This is were Im having trouble at too, I currently got a 40 slow pilot jet and a 155 or 150 jet. After what I just watched, I have no idea what I am doing. Thanks for the help sir
40 pilot jet way too rich . .normally these carbs run a 35 pilot jet and a 115 to 120 main jets with needle clip in middle position
Depending on elevation
Hey I ran my mini without a exauhst thing sounded like I was underwater then this genius told me I can warp my valves so I bought a cheapo one for the meantime till I grab that chrome 3stage center exit from gps the bubbly sound had me loving it tho I was gonna do a vid but I got discouraged
Does this apply to the fuel screw too?
Dam, was trying to tune my nibbi pwk & forgot about the idle screw 😂. The air screw was around 1/4 turns out. I put a 35 pilot now but no fuel lol so if its 1/4 out i need bigger when i put the screw at 1.5 turns?
Hey man what main jet were you running ?
Hey man just found your channel and I have a question. Im looking to build a mini bike from scratch with new parts as cheaply as possible. Unless there’s a kit cheaper then sourcing parts individually, what do you recommend. Right now I’m looking at Azusa frame but I can’t understand what tires and rims fit on the frame that work along with bushings.. thanks in advance
GoPowerSports has the Maverick98 minibike for less than $500 right now. The Rascal Lite is another inexpensive option for a complete bike.
@@Black66 cool I just looked at this kit and it’s a really good deal thank you. Also for the future, does a predator 212 fit on that frame?
I turn the air screw all the way out put the idle at like a 1/4 of the way in pull the bike over on choke if it doesn’t fire up turn the mixture screw in a bit pull it over then when it starts then I let the bike run for awhile at idle on a milk crate then i rev it up if it pops or backfires I add fuel how I gage if it needs a different jet is when it’s on flat ground and I’m on the bike when I give it gas if it doesn’t have good throttle response or if it it takes off decent then you feel like the power kicks in and not power all the way until you max out I rejet
I’m going to try this I’m having a hard time to get it fired up it turn on after 4/5 pulls
Sometimes if the bike sits awhile it starts rough and if you turn your gas off after every ride it needs to prime a bit I’ve noticed to get a first pull start pull the bike over slow a few times get it on top dead center pull should fire up easier
Does anyone know why I am still getting bad throttle response when I tried all the needle adjustment slots?
Do lean means to much power
im still confused, im running a 12-14 tooth sequential clutch with a 60 tooth axle gear and i have a gx200 with a big valve head (gx240 head i think), governor removed and a vm22 carb and when im out driving it doesnt wanna go sometimes i have to have it slightly about idle for a few the go and when i go to a bigger main it bogs when fully throttle, ive tried EVERYTHING and doesnt work beside idle jet bc ion got it also maybe doesnt help to be in sugar sand which is soft sand but does it on grass too
need help 😭
What throttle cable are you using with the pwk
Check out the build videos. The part links are in the description of the videos. th-cam.com/video/Qmoop0FkxOM/w-d-xo.html
What is the best carb for a 125cc apollo im running a nibbi 24mm 115 main 45pilot and it goes just bogs when i hit the throttle fast
Maybe switch to a 35 or 38 pilot. It could be bogging because it's too much fuel
Thanks man i moved the clip up a notch it leaned it out @thatcobradude4496
I have a vm22 on a pred 212 non hemi and I've messed with the screws some and still can't get it fired up it the engine has 18 pound valve sprins and a Billet flywheel any suggestions to get it up and running?
Vm22 requires the 17 pilot jet and 110 main jets with needle clip in middle position and air)fuel screw set 1 full turn out from seated
@dabtech7456 there's 2 adjustable screen one on the side and one on the bottom do both need adjusted?
I bought a pwk carb
Put it on a gx 200 (stock/header and 24mm gov delete)
105 main
35 pilot
Is that to big on the pilot and that’s why I have a bogging issue and sometimes if I give it throttle quickly it wants to die and slowly rises back
(Happens way often when engine is warmer 5-10 min of driving and it becomes nearly impossible to start going without the bog and slow return to idle ?
Same here. Pwk are more of a dirtbike carb. I bought a mikuni vm22 from gopowersports and it's perfect. No bogging on full throttle
Can I put a vm22 on a 79cc predator? I’m using a 120 pilot in Florida. Rn, lowest main jet I have is a 88. It won’t accelerate unless I leave the choke on…
VM22 is big. Check out this video, it shows the slide carb to use on the 79cc th-cam.com/video/Q59x_l7kiAY/w-d-xo.html
Cool. Very informative. Thanks. 19mm is the ticket
Can I use this tutorial to tune my Mikuni VM22?
Use this one...th-cam.com/video/MnQvIlFX8hM/w-d-xo.html
Nice vid! What altitude are you?
3700 foot elevation
@@Black66 perfect thank you, I'm at 5100ft and had a fuelling problem, totally diffrent jetting to my other bikes, turns out the float bowl was over fuellng.
I think on the pwk if you turn screw in its leaning mixture thats why bike idles low and shuts off and turning out richens bike wont turn off if you turn it out just idles bad correct me if im wrong
On the air screw if you turn it out it's leaning the mixture. You are letting in more air. On the fuel screw if you turn it out you are richening the mixture.
@@Black66it ain’t the air screw I have the same set up and it ain’t the air screw it’s the mixure screw which you left out of video ☝🏼
@@MoHunnidzGunCollections I explain the air screw and fuel screw at the beginning of the video.
@@MoHunnidzGunCollections air to fuel mixture screw is the air screw you dork lol
Would u suggest a 26mm carb over a 28 on mild built engine
Pwk only 28 mm suit the 212 better 40 pilot 130 main
@@zo-pm4bgyou kno you’re elevation?
I have a viper mini bike with a stock predator 212, the engine shuts off when I hit a bump too hard or come down from a wheelie too hard.. how can I stop this from happening
Sounds like either your plug wire is not tight fitting or your oil sensor is causing shut off. Disconnect the wire from your magneto to the oil sensor. See if that works
If Black66 gave my bike one pull he would be proud 💪🏼💯💨💨💨 long as the string don't broke lol so is he telling us to try these over the Vm22 skis
Quick question, whats your main jet?
I'm running a 120 in this set up. I live at 3700 foot elevation .
How do you tune for full throttle from a stop? I have a bike right now that’s tuned perfectly but if I’m stopped and I full throttle it, it dies completely and I have to restart the bike
Too lean or too rich
Does it cut out or does it bog
Yes I have this issue to it's like 1/4 to half throttle it dies but then wide open it rips not sure what's going on I think mine is lean. Help
@@spencerjohnson1499 adjust the needle to be richer
@@user-ru7he6qj2w thanks I did that's and you were Right it was the needle and a leaking intake manifold I sprayed it carefully with wd40 when I got it idling so it was a combo of a few things!
What does it mean when I start it up but will not stay on
Could be your spark plug air leak or carb bad
what frame is that?
Check out the GTS bike build videos th-cam.com/video/Qmoop0FkxOM/w-d-xo.html
what if it won’t run at all
Where should your idle screw and air screw be set at before you start any tuning, you don’t say this information
You should make your bike too rich/ lean and do a test to show how it sounds and how it affects performance.
Not gonna lie, I’ve kind of gone the way of the Nibbi carbs.
I’ve thought about it how are they?
@@reddaily11 great quality, power, and very easy to tune.
What shout I do
Just like the roadrunner watch out for the coyote
Mini bike wants to take off when on put a new carburetor on
Defective carb
Stay stock carb....... Less headaches
Slide carbs are the way to go. Never have a problem with them.
@@Black66plus you get way more power
Throw that in the garbage get a mikuni 😂
I say have fun with minibikes and use any carb. 😂😂
depends on what your building the mikuni is wank for my build
🤠👍
