Motorized Bike NT Carburetor Jetting in a Nutshell, How to Jet a Motorized Bike Carb

[@jameshuffield1755]

nice video. hoping to get my bike jetted this weekend. we will see.

[@JasonNosajasoNosaj]

Could you share or link the set of jets you bought? I'm unsure of what jet type/spec to get

[@arnulfob3454]

Awsome info !

[@justa3v862]

What did you set your needle at with the 65 jet?

[@barriosbuilds7688]

Stock, in the middle.

[@theLyzhendricks]

Just curious what jet comes stock in the carb

[@topdog3407]

normally a 70 jet

[@theLyzhendricks]

@@topdog3407 if u listen to how mine runs in my newest vid in ur opinion do u think that I need to put a smaller jet yo lean it out I think its 4 stroking could be wrong was also told to lean can cause 4 stroking soooooo I'm just a lil confused i think it might be rich plug isint super white/grey seems darker

[@theLyzhendricks]

@@topdog3407 btw I haven't messed with jetting at all it's a stock yd100

[@theLyzhendricks]

@@topdog3407 is it yhe same for the bofeng carps

[@topdog3407]

@@theLyzhendricks darker and wet plugs normally indicate too rich or too much oil. the engines also take about 5mins to run to warm up before they stop 4 stroking. are you breaking it in? because if you are just ignore it until you put less oil in the ratio. then when its fully broken in i personally run 25/1 on mine but if you have fully synthetic oil use 32/1 AFTER breaking it in. Worry about the jetting last once all that is done.

Did you end up going down to a 62 or 65?

[@Westhelockpicker]

I have a 66/80cc engine with high performance head and exhaust with a ported cylinder and my stock NT carburetor has the stock jet it came with and I know all bikes are different but what would you guys recommend I start with and bikeberry has jets in order

[@2strokezoomies]

Ordered me some jets from Amazon I get to about 25ish before I have to start tweaking the throttle to get faster but I can get to 37 downhill Hopefully the jets make it pick up without having to jump the throttle on straight/uphill

[@Sacmauthegioi19]

fuel does not enter the combustion chamber. what should I do.

[@barriosbuilds7688]

Make sure your jets are clean, the tiniest of things can clog the jet up. And nothing will get in the combustion chamber.

[@mikegamba580]

Yeah clean your jets and all passageways in the carb

[@DirectCurrent4u]

It aint got no Gas in it! 🤣

[@life-c9w]

bigger jettin hole more gas more power ?

[@barriosbuilds7688]

Exactly, can’t go too big or the engine won’t run right.

[@quintenmcpherson3471]

Mine just broke when I tried to take the jet out

[@RedditForSleeping]

Vroom vroom

[@tolanstout]

My NT has 5mm jets despite Bikeberry claiming these carbs take 7mm or 8mm jets.

[@melvinchamberlin823]

I got a comment maybe you help me not sir I got a 70cc 2-stroke motor bicycle motor and I was going to put the cable in the carburetor and a piece is missing where it hooks to the cable and on the carburetor it ain't got no numbers on it is look like Chinese writing but I can't read it it ain't no numbers on the outside anywhere how can I find out what it is or can I buy a new carburetor same kind of like that but I don't I don't have no numbers I don't know if any numbers inside of the gas ball bowl or not please let me know if I'm buying a new carburetor it don't matter please let me know okay thank you sir

[@barriosbuilds7688]

Seems just to be the NT Carb, below I included a link to a random website I found claiming to sell the cap that your looking for. But I would be worried from ordering parts from weird websites. And if your up for it, for another 8 - 10$ you can have a complete new carburetor from Amazon. That’s one of the great things about these bikes, all the replacement parts are super cheap! mbrebel.com/product/nt-carburetor-motorized-bicycle-used-parts/

[@arturtoma33]

I know in normal speed is 35mp.h in km 58km.h.

[@DirectCurrent4u]

My bicycle will do 29 without a motor with just the peddles!! 50mph should be the minimum speed I wanna go with a motor.Thats the whole ides of building a motorized Bike to go a Hell of a lot faster! You forgot to talk about air screw, fuel mixture. Pilot jets Needle adjustment. etc,,,👍
