Use nylon rope in the cylinder is much safer and won’t cause no damage!

Who builds racing engines?

Really? Don’t even show how you got the damn thing onto the tire except for a 3 second speed up? Worthless

Hey bro -- what is that big expansion chamber exhaust off, that big bore motor sounds awesome 👍👍👍

Helmet? Organ Donor?

Dude , font want /care about air filters, am interested in the carb and specs on it.. They good carbs... Do they use 4mm or 5mm jets? (Thread size)...

Здравствуйте подскажите пожалуйста у этого цилиндра покрытие никосил или чугун?

Can this type of engine be mount on a 49cc chinese standup scooter by chance?

Is it possible to get this type of engine on a chinese gas scooter?

I feel u bro. Stuff like that once ina while... it gets me too.

Idiot telling lies.

How much did u port the pistons

Bro, please modify a 49cc cvt.. x2

Please make a follow-up video where you detail the complete setup on the bike for every cable and hose.

Hi, I'm try to get a gas tank for my 110cc x7 pocket bike. You know where I can get it thanks. Thanks

Full circle crank increases primary compression, giving more power in mid to higher rpm. The half crank gives better low end torque. half crank i find to be smoother running if well balanced. Great for everyday use.

the plastic not on there why its loss seen primal rc put it on and it wasnt on there

I haven’t done the research on CO2 but I am curious since my shop is working to develop a drag racing division for scooters and pocket bikes

Tks 4 Cu gasket spray

Nice build…

If you want get a smaller rear sprocket at least 3 or 4 less teeth,You will go faster,much faster,front one makes only small difference if you go larger.

Where can I find parts for these engines? I have a few I want to pull out of the shed that have been in there for more than ten yrs

Blow torch. Fuel tank. Bang.

you sound like Mr. Wormald from Better Call Saul. Thanks for the video

what does have this to do with being a bad product? you just handled it wrong.. that is your fault, not the product.

I commented

Serlok bengkel nya dong bang mister, trima porting ga . Ongkos brp bang mister

what does this do to the bike?

A fellow Minnesotian 🙌

I know what you mean when things are going together way to easy, I get worried, and wait for the axe to fall

dude this sucks my 100$ pocket bike is broken oh no

This guy combined 2 such engines into one engine kzfaq.info/get/bejne/gr5jmtKCv7anlnU.htmlsi=7C6-VFfGgrHFjrwg

Ok i might sound crazy..... But can. You make an gear box for this engine by modifying a non working 4/5/6 speed engine into an transmission and attached this to it... And show us the results.... Cuz nobody made on KZfaq made such thing....

hey where you think i can buy one of this bikes i had one when i was 10 and they were fast but i cant find them now they have the one with the transmition they are slow where you get this one pless pleesssssss

Sad to see you go

What the size of the woodroof key?

What other engine fits it?

That’s a gear reducer

They also make what’s called a rocket key

Is this supposed to be a joke? This has to be a joke!!!!

poor engine almost stalled because of the Co2

What size is that strut in the rear? And do they sell them taller for our bikes?

Lol you been at it for awhile

I'm 250 and stock is 25 mph

To keep the button from getting stuck you need a pressure regulator between the button and bottle to keep the pressure from overloading and keeping the button from going down its only rated for a certain amount of pressure.

Bro!! You are such a badass.

Very nice. What block is that? 406?

is this engine for a pocket bike, sorry but you didn't say , so We had to ask.
