Dude you literally made this a lot harder than needed.

THANK YOU, simply for showing and bringing me through properly losing the air box for performance. I just moved to a small city in Colorado, and I’ve been fixing scooters , doing bore kits, but I haven’t found a proper showing of exactly how this is done.. you just helped me make more money in these crazy times!

Instantly subscribed when u said people dont be showing you nun you gota be seeing

Very nice clean work. All matching clamps on everything. Again nice work!

Thanks for spending your time showing the details.

the PCV valve is used to scavenge oil fumes, and blow-by gasses from engine combustion into the intake to be burned, as an emissions consideration...however it has a secondary, and far more practical use, which is to create negative pressure in the crankcase, because this helps prevent oil seal leaks, and oil consumption. Routing it to the gas tank will not at all help, and sadly, will likely somewhat contaminate the fuel, as when the engine is cold, condensation is a major consideration until the engine achieves operating temperature. I don't believe i'd route it to the gas tank. I would instead "T" it into the main vacuum port (after the PCV valve --which is the black plastic item in-line between the valve cover vent and the gas tank in your video). Since the connection on the gas tank is also meant to route fuel fumes to the intake, a "T" there would possibly be appropriate, although, it's better to just use a short piece of vacuum line and a fuel filter (to allow it to breathe without allowing debris in) because the fuel tank can't be counted on to be airtight, and thus vacuum tight..which would create a vacuum leak. In summary: I would route the pcv to the intake, and route the gas tank vent to a short piece of line with a fuel filter on the end, for maximum benefit.

Nice job mike! I always enjoy your videos

This is exactly what I need to see perfect video

That fuel line looks a little short i would make it a bit longer so your suspension can travel and not rip it off . That black and red thing is a petcock and that hose connects to bottom of the the tank or . That hose off the manifold should be plugged off because that NCY carb has no Air cutoff valve and that is a vent on the side of the carb that should be left open , The case ventilation hose should be left open in that case and mounted high so you get some drain back ,that one way valve will work but it is so cheap i would not trust it . And running that crank case vent line back to your carb is sort of useless with a open element air cleaner it can be done but why ! Nice manifold and carb set up

Got a new nibbi carburetor was so confused on the hoses thank you so much!

Very detailed!!

I appreciate your time and help

Am I the only who laughed when he said “ for offf road use only cuz we live in California 🤣 lmfaooooo I feel you man i live in San Diego

My SYM carburetor scooter over half year that engine does not working in Taiwan! Due to my fuel tank located within under SYM scooter pedal, and I try to push scooter start motor switch and then I got some situations as below: (1) engine cylinder pressure is 126psi (2) spark plug has flash (3) fuel tank is not pushing gasoline through the fuel filter out? It seems my scooter fuel line system has block issue, could you offer some suggestions to help me fix my breakdown scooter here, thanks!

Awesome video

This video helped me alot wish other ppl showed more and explained as well

Thanks for simplifying the system you guys are great! Post more vids like this please! :)

Thanks this is very helpful

Your vacuum line coming out of the crankcase looks like it's being pinched by that zip tie. It might not be fully closed, but you may want to cut that zip tie & fit it a little more loose with a new zip tie.

Just wondering how wet your K & N gets when you ride in the rain? Probably not good in wetter climates since the filter is right in front of the back tire and probably gets hosed pretty good.

Newsubscriber lets c what u got best south africa

GREAT Video, this I like !!! But now a serious question because I realy don't know much about scooters... I have a 50cc Rover Retro Scooter with (as far I found out) also a GY6 carberator. (4 stroke) and it LOOKS exactly the same like yours.. But with another huge black plastic filter..Question: Can this way of "wiring" also be done on my carberator/scooter?

Can i just let the positive crank case ventilation just vent ?? Or do i have to attatch it to the gastank?

Nice

ok thanks good video

3:30, you should have used a short piece of hose on the opposite end then hookup the bigger hose.

Where did you buy that one passage way ventilation crank as you call it?😮 it is a ventilation solinoid.... where did you buy it???😮

Don't buy the blue fuel line from Amazon it's cheap and degraded in one season. Residual gas from sitting probably was the culprit. I recommend using the black fuel line.

Can those of us who don't see the importance of the positive crankcase ventilation also remove that system because these systems are unnecessary sources of problems and leaks on scooters? Then, the fuel line from the tank can be connected directly to the carburetor with a manual switch?

Can can you show me how to hook up the fuel lines when there's two lines coming from the gas tank

question: if I removed the fuel petcock and used a fuel manual shut on/off valve should I plug both manifold stems since I dont need a vacuum pump anymore

That's a ncy carb? Looks like my oem carb on my 50

I have a Baja 150 exact same engine any tips to get it started it’s turns over but doesn’t start

Is that a gy6 B ? And are the carbs on gy6 supposed to be rear facing like this?

What if your gas tank is lower than your carb but still getting fuel?.. Sounds like it wants to start but has a put. Tried adjusting the idle

Clearly with street tires you don't use this for off-road use nice usage of the word and the language however not sure if you're scapegoating anything by saying that

Where can I buy one of those filters and shut off valves?

I don’t understand. Running the Crankcase vent to the gas tank? Won’t that put oil in my gas. What’s the work around?

I got one of those red and white on and off switches for the gas line on my moped didn't have it every long and its plugged up these things are junk and unless

does that Plastic shut of valve holds for like year of regular usage?

Looks like the same chasis of yamaha grand axis 100

Do I put a hose on like u did for air intake

what size k&n filter fits on the 30mm NCY carb?

How long can I run it with crank case vent disconnected? I need to see if I can get my started

What happens it I leave the crank line disconnected? I deleted the air box and my fuel tank doesn't have another inlet only one outlet

My peacock is screwed into the fuel tank is there an adapter that screws in place of the petcock to a fuel line hose bib

Will they fit on a Honda beat 125cc in the Philippines let me know thanks

I bought a new carb and my original carb had a manual choke and my new one has an electronic choke but I have no where to plug it in is it necessary or can I leave it hanging?

What if i don't have a vent on my gas tank?

Besides the vacuum and fuel lines that you explained, there are two other thicker black hoses on my Evo 150cc Taotao scooter. They start off at the right-hand side of the scooter. One of those hoses goes to the front of the scooter's where it is connected to the engine. The other thicker black hose is connected to what looks like a black canister at the right-hand side of the scooter's frame. It is located on the frame between the fuel tank and the ignition high-performance coil box. However, at its end, this thicker black hose (about double the size of the other vacuum lines) is not connected to anything on my scooter and is just hanging by itself. I am suspecting that it is the reason why the scooter is not starting. Also, on the left-hand side of the scooter's frame, there is what looks like another black canister which has two hose connections, one small another one bigger, but then there are no hoses connected to it. I suspect that the lose thicker black hose that is dangling in the middle of the scooter fell off from that. May that be the case? However, I don't want to connect that hose to the black canister on the left side of the scooter because I am not sure that it is supposed to be connected there. So far, I have searched in vain and have not found a KZfaq video with an explanation of the purpose for those thicker black hoses on the scooter. Are they part of the scooter 's vacuum system? Please advise. I look forward to hearing from you. Your explanation will be highly appreciated.

how did you hook the hose straight to the gas tank isnt there a petcock or valve under the gas tank did you remove it ? or how did you hook it up

From my crank case, i added a small paper filter. no tube back to my gas tank. you think that will be ok? I haven't noticed any leaking.

Question: I have a 50cc TaoTao. I upgraded fuel line, filter, carb n added shutoff. I reduced my fuel line from 1/4 down to 3/16 after the fuel filter since where it connects to carb the 1/4 line was way too loose. I had it running after all upgrades were done but now it Doesn’t wanna turn over. Seems like it’s starved for fuel. I see u put silicone over the connection where the hose was too big. Could reducing fuel line size after the filter be my problem? Did U use regular silicone? Thx

Hi, why did you eliminate the petcock? Is there an advantage in doing so?

🤝🙏

Does anyone know if I could put a Honda cable operated carb on my scooter I wanna eliminate vacuum lines just go old school like a carb off the 110 atcs something like that would it work

Where did you get your 'one passage way ventilation' that you mentioned?? It is not in the description.

The ccv vents exhaust!! Godd$^&^! Youre putting exhaust gas thick with carbon, back into your fuel. Carbon robs the oil of lubricity.... so get it outta there!

Venting the crankcase into fuel tank (especially without an oil separator) ?? Ummm, Nope. Sorry, I don't like oil in my gas tank.

I have a gy6 49cc I'm putting a manual shut off valve on it been siting for 3 yrs not starting someone put caps on air intake part need help

Is the gy6 the Lance scooter engine?

Is the manifold vacuum completely plugged off?

Can't I put caps on end of carb where u put hose at for air

What adapter did you use to get rid of the vaccum petcock? My petcock is on bottom of my tank and I'd prefer a manual one like you folks show.

mm

O

Hey bro do u have fb I need help with my gy6 49cc not starting my name is Roy bray in red shirt on fb

Jesus H! ! Way too fast for an instructional video. SLOW DOWN! Are you one Speed?!

Can you show me how to hook up the lines when there's two lines coming from the gas tank
