Other than the NT not sealing all that great I'm sticking with it. I am not wasting my time trying to re-jet the Hp carb and the OKo personally I think it's too heavy for what it does. Not to mention I want everything inline not off to one side. Great video though Tony, Keep up the great work loving all the videos.
I hear you. There are bikes I have that the NT carb is perfectly fine. Then others the HP is great. That’s why I’m building the pink bike. So I can put all the crazy stuff on it 😁
@@tonytaylor5087You’ve definitely got some stuff I haven’t seen/didn’t know about!! Like the throttle for instance… I like the design.. and your expansion chamber!!! Dayum!! Got some nice welds!!! $pendy I’m sure! I’m gonna have to subscribe now,because I want to learn more! My son convinced me to get a motor finally…. So,new to this for sure,but learning fast!!! Just put an expansion chamber on last night….. hooooo-weeeee what a difference!!!

I know you already have the dio reed, but there has been some heated arguments on weather or not the OKO carb gives better performance with a G2 reed or a DIO reed. It would be great if you could make an episode on this subject.
@@tonytaylor5087 I personally run a G2 reed with the OKO on a YD100 and it RIPS. The thing has SO much torque, it'll buck you off if you arent easy on the throttle. Ive heard the Iron Bore engine has even more torque, so pared with an OKO, decent reed setup, a half decent spark plug, and a decent exhaust, that thing will be a beast.
Carb 1 has occasionally float balance issues and the lil float mount tab imo especially when I hit jumps or bumps. Its still awesome but once you bend over the prongs trying to make it cut off gas flow earlier I never got it back right. But I still found it very dependable and a side tap w a screwdriver on side of the bowl is instant fix. I upgraded to HP and its ok for 14$amazon. Anxious to try the 3rd option i didn't know about that one till now 😮 thanks for your opinion brother 😊
My hp carb is not working on my motor and i took it apart and it looks fine but i noticed that there is an air bubble in my gas line so it seems to be not sucking in gas properly? Can anybody help with any info
How is everyone putting on a big pwk carburetor with the stock throttle cable? Mine needs about another inch or inch and a half of cable coming out of the housing and it does have a choke you actually touched it several times
Good morning and maybe someone can help but i recently installed a HP carb and now I can’t get full power and now when I engage the clutch the motor cuts off!!!!!! Can anyone help
I’m using the 24 mm oko carb and it’s got 105 stock main I replaced it with a 130 now it’s runs good but if it was a 21 mm it would run good with the 105 and better with a 100 I’m looking for to trying the mikuni tm24 on my other bike
i have the first old carb (the one who leaks fuel by air filter, lol) and now i bought the NT carb, and a new acelerator cable, and i dont know how to tune it properly. im using a Z or curved intake cause it dont fits in my mtb bike frame and it happens that have to much lagg on decelation, and some times it remains acelerated. please anyone can helpme to fix it?
How can I fix no fuel going into the engine I've bought another nt carb and am still having the same problem tried cleaning the jet I don't know what else to do.
nt crap carburetor: stock, no jet adjustment, 12mm air/fuel mixture inlet, restricts the engine, makes the engine too rich hp: a little better but a Chinese copy of the 15sha whether in 15mm or 19mm model oko: the best possible
So I got the 60 680cc upgrade it came with two heads and for the carburetor one black one blue air cleaner one larger head one smaller your head which goes with which
Looking forward to seeing what to do with the iron sleeve jug as I have a couple of them. It's obvious that some work is needed, but I don't want to ruin it. I also have an oko carb.
I've cranked down the clamp on the NT carb so tight I thought I was going to either break the clamp or have it cut into the carb. I could probably THEORETICALLY pick my bike up by it now.
That's interesting. I tried an *HP* Carb on 3 different builds and got the same result(s)...Engine WOULDN'T idle no matter what I tried to do, although they DID run, wouldn't idle. Never tried the OKO, and the NT just gives me the best results and performance, but that's just me I guess...
Choke flap keeps vibrating loose an fall down choking out my engine i tried everything i could think of but it kept coming loose so I took it off and use my hand for now until I get a better cars
I used some blue thread locker on little nut if blue don't work use red. Torque snug to where choke lever is a little hard to move but not way too hard & let thread lock dry. Or might try tighter to where lever is hard to move then slightly bend choke flap away from carb hole.
The HP the seal on the fuel intake there rubber you can't get a replacement the others fantastic!.for one second with covid you should have seen the fully F@#@ out the box basically the hole engine had no one straight join fit and all but the primary piston had gone including the clutch in a year half a seal in the primary case missing after my first cheap Chinese that the carburettor went 3 months I got Australian upgrade that ran it's time perfect bloody awesome on nitro!. but the first try clutch was stuck so got a apparently upgraded and it's stock china standard at full upgrade price???.😃😄😁😆😅 5 Smile's Oko for me!. And the standard will do it's time use at moment!.
the NT is a leaky boi but it's the only one i can stuff on my 100cc 26 incher. it's already been a bit smushed by the engine and as it is i don't exactly have a top bar...
OK so where did you get that sick azz expansion chamber exchast on that pink bike from? I looked all over yalls site and couldn't find it. Right now I'm running a yamaha yz85 expansion chamber on my 80cc motor, reed valve 32mm carb, (came off the yz85 as well) having problems with rear motor mount. Has the 8mm motor mount bolts. Not enough room to put on bar. I'm using a 1972 schwinn has a bigger opening. Planning later on doing either twin motors or a 10hp honda 4cyl maybe even try putting a 150cc dirt bike motor. There's that much room.

@@tonytaylor5087 I hear you, If I had the money to just build the ultimate Bike it would probably do over 100mph with or without a rider. LOL
Use Teflon tape to get a better seal on intake to motor
Keeping everything in line will cause your carb to suck hot air but you do you

Thanks for the info. Looking forward to the comparison videos.
i took small engine repair back in the early 80's so i know everything you say is 100% true
Also that cylinder takes a 49mm piston instead of the 47mm I hope the kit you ordered came with the larger piston
i have a little question what is the better size jetting for oko carb on 80 cc thanks
I like that 21mm OKO Carb with my 80cc Reed Valve set up! It's a real Monster for sure! 💯👍
Great video,
Where did you get the expansion chamber on the pink bike from? As I would like one for my bike.
I noticed on a couple of things you don't know what you're talkin about that is not an air fuel mixture that's an idle set
what pipe do you have manZZZZZZ?
I know you already have the dio reed, but there has been some heated arguments on weather or not the OKO carb gives better performance with a G2 reed or a DIO reed. It would be great if you could make an episode on this subject.
Great thing to test! I’ll definitely dive into that.

Oh good to know!
On the Hp carburetor what jet you using
65 for me

Okay my question is the high performance carb how do you get the right idle
Best carb for 49cc SYX moto 2 stroke with goofit big bore kit (54cc)
Any suggestions much appreciated
My hp carb is not working on my motor and i took it apart and it looks fine but i noticed that there is an air bubble in my gas line so it seems to be not sucking in gas properly? Can anybody help with any info
Did you check the gas tank
I'm running a stage 2 blue head with a HP Carb Banana Pipe shes a beast looking to get out and ride this summer
Is this for the 100cc engine too?
I need jets for the nt ? You don't sell them on site? there 6mm I'm pretty sure
How is everyone putting on a big pwk carburetor with the stock throttle cable? Mine needs about another inch or inch and a half of cable coming out of the housing and it does have a choke you actually touched it several times
Good morning and maybe someone can help but i recently installed a HP carb and now I can’t get full power and now when I engage the clutch the motor cuts off!!!!!! Can anyone help
thank you! this isvery helpful
Will these carbs work for a 50 cc and 100 cc 4 stroke?
If not what do you recommend for a higher performance carb
Great vid, gotta correct ya on the hp carb tho thats not air fuel mixture its idle adjustment screw 😊
do you use a grinder that is powered by an air compressor? for big[more difficult] jobs it would be better than a dremel
Y’all where does the that red line plug into on the oko?
I’m using the 24 mm oko carb and it’s got 105 stock main I replaced it with a 130 now it’s runs good but if it was a 21 mm it would run good with the 105 and better with a 100 I’m looking for to trying the mikuni tm24 on my other bike
true the cnc intake is a tighter fit and it doesn't have a bend that can cause a problem
I just bought that carb. Is it going to be ok without the reed/barrel setuup?
Can you do one about a Bofang carb ? I bought a kit from bikeberry and now cant find tuning jets .
it uses predator 212 jets
i have the first old carb (the one who leaks fuel by air filter, lol) and now i bought the NT carb, and a new acelerator cable, and i dont know how to tune it properly. im using a Z or curved intake cause it dont fits in my mtb bike frame and it happens that have to much lagg on decelation, and some times it remains acelerated. please anyone can helpme to fix it?
The carb on my pk80 ive never cleaned filter or cleaned bowl i a run a 91 gas and have had over 2,000 miles an now im going to clean it
WHAT SIZE ARE THE MAG WHEEL BEARINGS NEED TO REPLACE THEM
Kilroy was here (where do you get that CNC intake?)
I got the sha carb coming from grubee
How can I fix no fuel going into the engine I've bought another nt carb and am still having the same problem tried cleaning the jet I don't know what else to do.
nt crap carburetor: stock, no jet adjustment, 12mm air/fuel mixture inlet, restricts the engine, makes the engine too rich

oko: the best possible
So I got the 60 680cc upgrade it came with two heads and for the carburetor one black one blue air cleaner one larger head one smaller your head which goes with which
For the NT with it being loose I added some gas line Teflon tape to seal it on the cast metal one
Looking forward to seeing what to do with the iron sleeve jug as I have a couple of them. It's obvious that some work is needed, but I don't want to ruin it. I also have an oko carb.
I've cranked down the clamp on the NT carb so tight I thought I was going to either break the clamp or have it cut into the carb. I could probably THEORETICALLY pick my bike up by it now.
Tell me about altitude adjustments and performance at 7 or 8,000 ft above sea level .
Really all you need to do is jet a bit leaner. Start at like 65 and go lower or higher as you need to
For the NT with it being loose I added some gas line Teflon tape (Amazon)to seal it on the cast metal one
The NT and HP carbs are very good but it may come when you a better overall tune or more air to get in.
HP carburettor is the one high use and it's perfectly brilliant never had any problems.
how high?
Theres a problem with my 49cc where it doesnt go idle and it instead stalls when i stop going fast
your rpm is low.Turn the screw on carb to increase rpm
For the NT with it being loose I added some gas line Teflon tape to seal it
The carborator is not working or fiting I tryed making a off set intake joint but it's not working correctly
My bike runs with a high Rev and when I stop with the clutch in it will Rev very high how do I bring it to normal idle
You got a vacuum leak
In-between your carb and cylinder head you have an air leak,,, THAT is what causes high revving regardless of throttle position !!!
That's interesting. I tried an *HP* Carb on 3 different builds and got the same result(s)...Engine WOULDN'T idle no matter what I tried to do, although they DID run, wouldn't idle. Never tried the OKO, and the NT just gives me the best results and performance, but that's just me I guess...
did you swap out the jet in the HP to a 70? there jets are way too rich in them
Choke flap keeps vibrating loose an fall down choking out my engine i tried everything i could think of but it kept coming loose so I took it off and use my hand for now until I get a better cars
I used some blue thread locker on little nut if blue don't work use red. Torque snug to where choke lever is a little hard to move but not way too hard & let thread lock dry. Or might try tighter to where lever is hard to move then slightly bend choke flap away from carb hole.
Mikuni vm 18 is all I run on my wildcat pk80
That's not the NT carb it's the one they replaced it with that has nothing but leaking problems
The HP the seal on the fuel intake there rubber you can't get a replacement the others fantastic!.for one second with covid you should have seen the fully F@#@ out the box basically the hole engine had no one straight join fit and all but the primary piston had gone including the clutch in a year half a seal in the primary case missing after my first cheap Chinese that the carburettor went 3 months I got Australian upgrade that ran it's time perfect bloody awesome on nitro!. but the first try clutch was stuck so got a apparently upgraded and it's stock china standard at full upgrade price???.😃😄😁😆😅 5 Smile's Oko for me!.

Also there are no pedaling options
My hp carb made mine slower
HP carb sucks NT speed is better
the NT is a leaky boi but it's the only one i can stuff on my 100cc 26 incher. it's already been a bit smushed by the engine and as it is i don't exactly have a top bar...
