No problem bro many carbs on the market nowadays but the key is to not go to big for your engine set up. If your engine is fairly stock stick with the smaller N/T and Hp style carbs. But if you have do a lot of porting or have a real pipe on it a vm18 or pz20 may be the better option for you.
@@keeganhache6667 Don't forget when You talk about Jetting your Carb You need to mention that Jetting also depends A LOT on your Altitude!! The higher, the altitude, the fatter the jet you will need! Keep up the great work my friend!⚡︎👍🏁
hey buddy dont worry about what other people think about what you do on your channel its your channel do what makes you happy and have fun with it . i do know how people get up tight about things in the motorized bike community . and not just the subscribers some channels freak out to if you have a opinion lol not mentioning any names . you will figure it out if you keep up with the other channels . you might already know lol . just dont sweat it there are a million experts and non of there opinions matter when it comes to what you do on your channel .
Yes unfortunately this has happened more than once but all you have to do is ignore the negativity and keep making the videos like I did before. There was this one guy saying “you don’t know anything and your never right”. How ever when I clicked on his page all he had done to his bike was a banana pipe so it just goes to show how ignorant people can be.
@@keeganhache6667 its all good buddy just block him and keep doing what you do. he is just one person in a ocean of people . you will meet people like that alot there just not worth the time . ride safe little buddy
I noticed there's some strange rangers in the MB community. One guy kept calling me an idiot for saying engines can run on hydrogen, natural gas, mapp gas, propane,etc... Despite me showing him an overwhelming amount of evidence. He said it was all BS/a scam, that I was wrong/stupid & he was right. He's messed with 2 stroke engines quite a bit but apparently hasn't ever seen a common propane forklift.
I closed my petcock the other day and noticed air bubbles coming up my fuel line as it was draining into...somewhere? Bottom of my air filter is soaked, so obviously there. My float was at like 17 mm so I moved it to 21. Put some fuel in the line to check and no bubbles, level hasn't dropped. Can't wait to try it out in the morning - maybe I'm finally on my way to getting this thing running right. 😂 I really appreciate it, brother 🙏
I saw that the other day also. Seemed like it went on and on... Almost like my fuel was boiling. I think I'll try moving my float as well. Hopefully it will help with my 4 stroking issue.
Thank you for a well spoken & informed delivery. My question is: is it normal to get an NT with a float that has fluid inside of it? Incidentally upon my first start up it bogged down after about 3 to 8 minutes.
I had this same problem with mine last summer. Your float level is incorrect. Adjust it to 21mm. Also there will be a point where you have adjusted the float flap so much that the metal has become weak, and you will need to buy a new n/t carb. Or a rebuild kit
Dont know what its called but at the end of the throttle cable, the brass pin with 4 or 5 different washer positions. I live at 5k elevation, What notch would be best?
I needed a filter coz me rear tire was slinging sand & dirt directly into my carb intake... I had good results modding the stock restrictive NT carb filter by, #1 cutting off those 4 bottom plastic intake tubes on the cover, wrapping tape around the outside so airflow can no longer be sucked into them. Then cut a large oval hole in the back cover, cutout the inside plastic filter support screen (leaving the outer plastic ring & screw holes) Now it runs just as good as it does with the filter & housing completely removed. But if I remove the tape so the bottom holes are also exposed. It doesn't run nearly as good, I suspect because the holes are causing the airflow to swirl inside the filter housing VS being sucked straight into the carb from 1 large oval hole cut back. In hindsight, I should have only cut 1 large round hole in the cover, directly inline with the carb intake hole (while also plugging up the bottom holes). To see if it'd run just as good with smaller round hole VS the large oval hole made in back. I made the hole oval & as large as possible, going for the least restriction.
Wow sounds like you really dialed it in! I always recommend running a filter but as you stated getting the most flow out of one won't hurt either. This goes for a lot of things on these bikes you just really need to experiment with what works good.
@@justanothermotorizedbikech5138 awesome man just make sure you have really powerful brakes those motors out of the box still in break in can hit 50mph no problem
the kid i bought mine from is a grade a duster because as soon as i put gas in it, gas practically pours out of the filter, and when i took it off, i realized there’s only one screw and no gasket. could it also be the float height, or should i order a new filter?
Hi. I think I might have this issue, i might try what you are saying. I am noticing quite a bit of gasoline leaking into my air filter, i have the same nt speed carb you have.just needs figure out where to drain the gas out of the carb to
In my case I always had to put in a bigger jet. Would run great up to 3/4 throttle but when I would give it full throttle it would just bog down cause it wasn't getting enough fuel. One of my engines I ended up with a 78 jet
@@keeganhache6667 not just a regular china doll I have every performance part they make on all my engines except nitrous but now that I know I can get more cartridges I'm getting that too
I'm trying to find some type of gas/oil resistant non hardening/non messy putty to wrap around my carb/intake to insure no air leaks. So far the free window putty string I had laying around is working but I'm not sure how it holds up to gas & oil. I didn't wanna mess with smearing messy gasket sealer all over it, having to wait for it to dry & scraping it off & reapplying each time I removed the carb. Would be nice to have some reusable putty. It'd also be good to carry some with you & come in handy for something like a leaking petcock valve or cracked fuel filter. You could stick some putty on it & make it home.
There is the stuff that I've tried out in the past and have had really good luck with there's a sealent called permamax The Right stuff. My dad's aluminum intake was leaking on his truck and it was because we just used ultra Gray which is good for light duty stuff so we use this permamax right stuff and it's easy to remove if you need to but it will still seal 100 percent.
@@keeganhache6667 Just seen they make several types of "the right stuff" ...I have maybe 5 different types of gasket sealer/maker laying just never bothered to try em on the intake yet. I start typing away posting comments, not realizing how many & long they are, lol.....Since $5 gas is probably here to stay for good, I'm working towards a lightweight 40-45 mph, stealth motorcycle with pedals build that gets 80-100 mpgs.
hmm idk but what is that screw near chock? u dont have it but i have , does it makes fuel go faster in or what? i just dont know why my moped wont stay runing , i clean it few time but no result....
You can lock tight has heat resistance so a lot of people use them inside engines. So putting it on the cylinder studs is a great idea so they won’t back out when you Have to take the head bolts off. Seen that plenty of times
@@keeganhache6667 so my kit came with extra lock washers for the rear wheel sprocket? do I need a lock washer on both sides, or just on one? sorry to bother you again
@@audieallen9734 no all good to answer your question you need a lock washer and flat washer on the nut side so the back side. Not the front because you need clearance there for your frame
Yeah so you can’t just buy your average 5mm jets for most carbs. What you need to do is type in 212cc jets and then you will find the right ones. It’s because it’s a 9mm jet and it’s a great carburetor just harder to find jets. Go powersports has a lot of parts for 212cc engines so that’s your best place to shop
do u get a VIN number and plates and register ur motorized bikes with the ministry of transportation in your province? in order to legally drive these on the roads in ontario, u need to do all that plus insurance and M(1, 2) license with at least L condition.
Yeah I live in Nova Scotia so the law here is that they can not go over 20mph. I have ridden my many cops and they don't care. My fastest build goes almost 50mph so it's honestly how you ride them.
@@keeganhache6667 be careful! Just because they haven't pulled u over, doesn't mean they never will. If u get pulled over and they prove the bike goes over 20, u could get a fined. In ontario the fine for riding without insurance is 50k.

Hi i have new bike kit and cant get it to run when i give it throttle i have bofeng carb ive moved the e washer all the way up on needle and its better but still wont let me give it throttle it will cruise at about 1/4 to 1/2 throttle and has issues with slight inclines
Yeah if it’s a brand new motor I would break it in with the stock carburetor then when the three tanks of gas are over then switch to a larger carb like the pz20 or Tm24. I know the break in period sucks especially if you have the upgraded parts already but trust me you have to let that motor break in right. Good luck to you
You pump that on the NT carb before you cold start. Pump it until you see gas coming out the filter. Then you'll be ready to start it. At least that's what I do and it seems to help with starting a cold engine.
No that will just flood out the engine remember to much fuel isn't good ether. All I do is pop the choke prime it 5 times and give it half throttle and it fires up first try.
You forgot to mention to wet sand the top of the float bowl. It is the cause of most chronic "mystery" leaks ( fuel and air). Do this after doing everything else you covered
That's why I said mystery leaks because after doing everything you said it was still leaking and the only thing left was the top of the float bowl. Good vid bro!
One way to find out exactly which part of your carb is leaking if you have a very slow leak. Is to stuff some pieces of toilet paper around the suspected areas then check it in a couple hours or day later. I couldn't tell if my carb was leaking from the bottom drain screw,primer button, bowl gasket, fuel line into the carb,etc..coz the leak was so slow it wasn't visible. The next day after riding, there'd be a small puddle underneath the carb. After stuffing TP around suspected leak areas over night, I could see it was leaking around the primer button only.
Yes this is totally a good idea I had this problem recently on my pocket bike and I just stuffed some shop towels underneath the lower fairing came back the next day and it turns out my overflow is leaking so most likely my fuel Peck cock isn't keeping the gas from flooding the carburetor.
Hp carb was meant for a 21mm wide intake try a bigger intake it’ll pump up ya jam! And I’ll make a video soon bout the hp carb and send to ya show y how to not have issues with it
Fuel was leaking out of the air filter...then I just pumped the manual fuel pump, and it stopped leaking, when I turn the fuel line on... With no leaks at all...
They painted the inside of my cylinder head. I pulled the plug & it had paint on it. It may be a common problem. I am correcting manufacturing defects! And I thought the climate was wrong for China to grow lemons.
I did a video dedicated to this topic! Be sure to check it out because I cover everything in it about carb jetting, needle adjustments, spark plug gap, ignition timing you name it.
Bofang if only 15mm and the NT is 19mm. Bofang uses special jets you can't get so you can't tune it unless you drill it out. Nt carb is the best. Other 2 are junk.
It could be the needle and seat itself. Overtime they will wear out and it will allow gas to overfill the bowl when the bike is perked. These carbs are cheap and easy to get so in your situation you are better off buying a brand new carburetor

Yes the rubber o ring goes inside of the carb and seals to the intake.
