Wonderful job 👏
You are a good man.
I do not predict very long live to the battery assembled like not standing position as it is a lead acid one it is made to use in only one way. Like this lead parts are partially not under acid and it ruins it soon! Good points for emission deleting!
I buy AGM (Absorbed Glass Mat) lead-acid batteries that are designed to handle being mounted any direction. The acid is soaked into a mat, so it can't spill out or leave any parts of the lead without acid.
Or change to lithium sealed unit
awesome video!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Just a great video,you know your stuff,thanks
a hose and line clean-up like that, is something that older scooters should have done **before** running problems arise!
thanks dude, i got one of those scooter
Hey! I just found your videos on here! I'm so excited!
I just picked up a running "Chinese scooter" for dirt cheap! It looks VERY similar to the one you have done videos on but it has cruzin150 and a model number (I'm assuming) on the rear fenders.
Where and how did you find an owner's manual on these things?!
I have watched what video's of yours I could find trying to figure out how to maintain this thing. 😂🤣
I look forward to your reply!
I have the same air box and all I did was removed the pcv part off my air box and put that back on my bike and ran the pcv hose and the cvt hose to that box and that was it. I'm going to buy a uni filter to replace the stock air box.
Hii paul nice video ☺️❤️❤️
If I want to replace all of PVC hoses as you, those PVC hoses does have temperature limit range? Are they special type? Maybe you give some idea, thanks!
The clear vinyl hoses are ok, but I've found using rubber hoses from the auto parts store works even better. Here's a newer video about it: ua-cam.com/video/0NwRbp6-vtY/v-deo.html
fantastic
God even scooters are overengineered these days
thanks!!
And hey thanks a lot man I have me a GY6 TaoTao scooter I pretty much
freaking modified it with everything just
about everything I have a little bit more stuff than you for my GY6 scooter I even going to make it a hundred cc with a
nitrous kit on it all I really need is synthetic oil the hoses like what you got I need to swap out my front shocks and I need a switch for my hoses and I need
the gas tank magnet to catch the shreds
inside my bike so it won't mess it up it'll make my engine last longer b. 💪😎🆒^
I was changing my fuel filter and noticed my fuel inlet black hose was only connected to the carburetor the other end come attached from somewhere where does it connect to
please answer!
my scooter has only one vacuum hose coming out of the intake manifold and goes to the carburator throught the gasoline line and the scooter seems to run better and smoother if i don't connect the vauum hose to anything. so my question: is it ok to leave it not connected and leave the gasses go to air ? or something bad happens? HELP!
.
NOTE: my scooter came without any emission system
Hi, I just got a 50cc 4stroke and the carb is shot and fuel and vac lines need replacing, I noticed that the carb in there has no vaccum hose to it, only from the intake manifold to the petcock, If I get a new carb with a vaccum port on it as most do, do I install a "T' from the intake manifold to the carb then to petcock, or do I plug the carbs vac line and set it up like it is? TY for your hard work
Yes, you should connect a vacuum hose to the side of the carburetor. It helps with the fuel mixture just above idle.
Hi Paul I have the same scooter just wondering if you know the issue I'm having it will tern on and run but after a few miles of riding at 30-35-40-45 or 50 it bogs and cuts power after that I stop and restart it and on I go but it dose it every few miles???????
Hi Paul, I have a '22 Amigo il Bello 150cc GYG scooter. Last week, I removed the CVT carburetor and installed a Nibbi 24PWK. All good, but for the thing bogging or stalling when I trist the throttle from a standstill. Once I get going, the thing runs well. Could you please advise? thanks very much!
Paul... thx for this info! One q... there's another vacuum port on the carb that is right next to the electronic choke unit... (just under the diaphragm cover) does that just vent to atmosphere... or does it also need to have vacuum line connected?
The port on the electronic idle enricher (choke) is a vent that goes straight down. It's an overflow vent. Pause the video at 3:07 to see it. It has a short hose (about 1.5 inches) with a right angle that doesn't connect to anything.
@@LabCoatPaul ... thx!
@@LabCoatPaul does this line need to have open air if i was to use a manual petcock could i use the vacuum line into the overflow
Is this the same system as a Lexmoto 125 vienna 2014?
Hi there Paul, I just installed a new gy6 150cc motor on my scooter and it started fine but the engine seems to be missing while idling. I looked at my clear blue fuel line and from the fuel pump, it seems to be pulling in some air bubbles and I was wondering if that could cause the motor to sound like it's missing. I've already adjusted the idle screw but the motor still misses while idling. Could the air bubbles going into the carburetor be the cause?
Thanks for any feedback!
adjusting idle screw does not fix misses, adjust idle mixtire screw. seal off any leaks
Can you this on any scooter in the Philippines let me know thanks
Great video, I have almost the same scooter with same hookups, how should I route the lines from my old air box? I have like 4 lines coming off of it and I want to put in a new carb and aftermarket air filter,,,TY again for the video
This video shows you the minimum number of hoses you need. If you use a foam filter, just jam the PCV hose between the 2 foam layers and you're good.
@@LabCoatPaul TY so much for the video, mine is almost like yours, but on my gas at 5:11 you have one fuel outlet from the tank to the pump , I have 2 outlets on the gas tank next to each other, why are there 2?
@@thedaydreamer7972 You probably have a vent tube. That's to let extra pressure out of the tank. Apply vacuum to each tube to see what comes out. There should be fuel in 1 and just vapors in the other.
I have a Roketa mc 07b-2-4. the egr on mine looks the same at the valve cover but that metal piece goes to a braided line and then what I'm assuming is a square egr valve but looks way different than yours. Then the fat line with the filter runs behind the carb out the left side just in front of the kick start. Does this sound like that same thing? My carb also doesn't have a vacuum hook up on the right side by the throttle cable like yours. Please help if possible! Thanks
The good news is you can probably just remove the emissions stuff and set it up like my scooter. On Chinese scooters that stuff doesn't really work anyway. If you want clean emissions, tune your carburetor correctly.
I have the same problem. My new 30 mm intake carb does not have a place for the vent line on it that comes from the "t" off of the intake...
were do I run that line too?
good vid i just wish it was a lil slower lol it was so fast i had to see it a few times now to try this on my scooter wish me luck
Good luck! I'm still working on finding the right pace for everyone. Pro tip: you can adjust the playback speed by clicking the gear in the lower right corner of any video on youtube.
Hello! Do you or anyone else know if it is possible to use a throttle carb on GY6 engines? I mean a non-cv carb like a nice Mikuni. Pros and cons?
You can change the carburetor if you want to. A bigger carburetor will get you more power if you've installed a big bore kit. If you have the stock size piston, going to a bigger carburetor could decrease your torque and horsepower.
I have a question, if I remove the stock airbox and use a cone filter right off the carb what do I do with the PVC system since it’s now just sitting there with two lines no longer connected to the airbox.
You can run the breather hose from the valve cover to your foam air filter. Most foam filters have 2 layers and you can just tuck it in between them. Basically this just allows the engine to burn vapors that come out of the valve cover. If you don't connect the hose to anything, that's OK too.
@@LabCoatPaul If you are running on the road full time drop the outer filter snuggie and use it for a beer huger... Oil lightly and main jet up another size...
And a real Gates belt stops all the friction and noise from any cvt...
Best 30 bucks you'll spend for power transfer...

I bought a 50cc moped Pagsta Regal Raptor recently, it looks like a small motorcycle. It runs kind of bad on 4th gear and higher speed RPM at full throttle where it kind of wants to die and does from time to time, always starts up again but it runs unevenly. I have checked some things and also noticed I have an EGR, do you think that could have anything to do with this problem? It seems the previous owner had broken of the airbox housing and left is only the EGR hose and some cables that go to it, I have no idea what it does, it doesn't look like in your video.
Disconnected hoses can cause a vacuum leak and would mess up your air to fuel ratio. I recommend setting up the hoses like I have them in the video so you don't have any extra stuff.
@@LabCoatPaul Thanks for the reply, I managed to get the bike running a bit better it doesn't die on me any longer but I can't reach a speed higher than 30 kmh (18 mph) and this bike should make at least 45 kmh, it seems to get power but just don't go any faster. I cleaned the air filter and will try it today and see if it runs better, seems it gets very hot after just a short time too. Maybe could have something to do with the air not being enough? I tried adjusting the air mix screw but it is almost turned in as far as it goes, about a half turn before it is maxed. Turning it out slightly will cause the engine to idle very fast, the idle screw is on the other hand turned out 3-4 hole steps. I am wondering if the main jet might be too big? Haven't got any smaller to try out with but it seems to get way too much fuel because the spark plug gets black from soot, bought a new one but still gets black and sooty.
Hello Paul 🛵👍. I purchased a gel battery recently & was wondering if that was a wise choice. My scooter has complete Leds & the charging system currently is a little over 15 volts at quarter throttle 🤔. Is that too much for a gel base battery ?? Appreciate the info 💯😎
Over 15 volts is pretty high. Gel batteries are basically a normal lead acid battery, but the acid is less of a liquid so it can't spill easily. I'm a big fan of cheap Amazon batteries for scooters. I just buy ones with good reviews and I haven't had a problem yet. You might want to try a new voltage regulator to see if you can get that voltage a bit lower.
Hi. Was wondering if heard of this one. I have out of the valve cover breather fuel and oil mix missing out. I have replaced the oil obviously and a new petcock fitted. I also have new carb to fit. Just don't want it happening again if its related to something else.
A little bit of oil coming out of the valve cover vent is normal. It's part of the positive crankcase ventilation system, or PCV. Piston rings don't seal perfectly, so when the engine is running some of the combustion pressure and a little bit of gas, can get into the crank case with the oil. The breather vent on the valve cover lets those extra fuel vapors back out. The hose should be routed to the air box so the engine can burn those vapors.
Too much oil or gas coming out of the valve cover can be caused by having your oil overfilled, having your carburetor tuned too rich, or bad piston rings.
That's just it it's not vapours it's actual oil/petrol mixed. Drained the oil and got way more out than I put in. It's like an actual stream coming out of breather. It filled up air box
@@LabCoatPaul Hi there, i'm not sure if you answer it as the topic was long before but in anyway i would ask that you mentioned pcv works as the recruiter for the leaked gas and oil to the crankcase. Crankcase should be placed bottom side of the engine. How can the breather on the valve cover blow that leaked oil and gas to the air system again as it is placed on top of the engine. I'm confused because these are far apart itself.
The PCV takes extra vapors from the crankcase and routes them back into the intake.
If you have gas in your oil, some of it will evaporate and go through the PCV back into the intake.
If you your oil has a lot of fuel contamination, change your oil.
The purpose of the PCV system is to prevent vapors from escaping into the atmosphere. It’s an emissions component.
Thanks for your answer but still i did not get it exactly. As far as i know the only pcv component in this bike is a port on the petcock and a hose out of it to the air intake. So, when gases pass through the piston and escape to the crankcase then how our pcv component recall them from crankcase to petcock again. It is a long way and it should be some vacuum or any other force that gases to be drawn out again. but inversely once the gases escape down the piston there is no force to take it out again upward to my logic. Please tell me if i'm wrong. In cars, there are some other hoses crankcase to connect air intake and it is logical but in this bike there is no direct connection between crankcase and air intake. So, i just dont understand how the escape gases in the crankcase can go back to petcock again without additional route like in the cars.@@LabCoatPaul
Noticed my 50 cc was leaking gas from the bottom..
Informative video, but how much longer before gas scooters are done anyway?
I'm guessing at least 20 years. Until electric scooters become cheaper than gas, the Chinese scooters will still be here.
@@LabCoatPaul Point well taken. They keep talking about ending gas powered vehicles, but how many people (especially in the lock-down economy) can afford to replace their present transportation with an expensive electric with much shorter range?
Gas motor scooters are very economical at 100 miles per gallon. They will be around as long as gas is available. There’s no reason why electric scooters will replace gas versions until the electric ones are less expensive and battery replacement is cheaper than engine replacement - that is a few decades away. And there are tens of millions of gas scooters out there. With proper maintenance and cheap replacement parts they can run almost forever - in third world countries they already do
@@drdrew3 here where i live, in Europe, Portugal ( where the Justiceystem,the courts, judges,are a royal stinking POShtt...) there are hundreds and hundreds of elec scooters for sale cheap because the battery in no good any more,and it costs a bundle to replace,so people just puts them aside; very very **ignorant** of them for following the hype and buying them elecs in the first place, a bad move at this time;
nothing like pulling up to a gas station and in 2 minutes filling up
LCP, get videos, I’ve got a couple questions which I hope you can answer. My scooter is similar however on my gas tank I have another hose besides the one for fuel. It’s on the right side of the gas tank and it runs to something I’d think is the pvc valve, then further runs to what I think is the egr valve, now the question I have here is can I just cut that hose and plug it up so no gas leaks out? Question 2, is it necessary to cut that piece off the air filter box or can I just drill a hole in and insert the hose? As for question 1, I can send you pix if I didn’t explain it well enough. Thank you, LW
If your gas tank is in the floor, like my scooter, you'll have a fuel hose going up to a pump, then to the carburetor. The other hose coming from the tank is a vent hose. It's routed to the charcoal canister to store the fuel vapors and burn them later. It's ok to leave that hose disconnected, but I recommend running it to the air filter box, so if fuel evaporates it can go back into the engine. Don't plug the fuel tank vent.
It's not necessary to cut parts of the air box. I just did it to have the minimum number of parts.
@@LabCoatPaul wow thx for your reply. I’m totally confused with the mess the previous owner has left and I basically want to eliminate any lines that I don’t need. Yes the left side of my floor gas tank is the line that is going to the fuel pump, then on the right that line goes to what I’d assume is a pct valve and then further to I believe the EGR valve. There is actually another hose going into that canister as well besides the line from what I think is probably a pct valve. On the other side of that canister is a nipple or stud or whatever it would be called to which nothing is connected, so I was stumped and hoping I could eliminate that whole setup. Like you stated though I will run that line from the fuel tank in the air cleaner box. Thx again for your reply. Gotta say again, of all the vids out there yours are the best, explained well and you seem to use the KISS principal and it’s easy to understand.
Meant pcv but iPad kept changing it to pct, sorry.
What bike is that? I need that tank and fuel system
Hi! I have the Roketa MC-16-150 scooter. The same scooter can have many different "brand" names. If it looks like this scooter, it probably is this scooter. I'm currently installing a different gas tank on my scooter, so you can have my old one. e-mail me at Paulz1265@gmail.com
I have a euro 5 50cc moped and where your replacing the PCV hose that comes of the air box and goes to the top of the engine can I take that of so I can put an aftermarket filter on
Yes, you can install a foam filter instead of the air box if you want. I recommend running the PCV hose to the foam filter so it still burns vapors from the crankcase.
A foam pod filter will make your engine much louder. If your stock airbox flows correctly, a foam filter will not improve performance.
A foam filter makes the biggest difference if you've installed a bigger piston and bigger carburetor.
@@LabCoatPaulwould you know where I could buy a filter with the PCV connector
@@morgantowns-qj6uy Foam filters don't have PCV connectors, just shove the hose between the 2 layers of foam.
@@LabCoatPaulthanks you help me alot I don’t know much yet hopefully soon tho ha
Hi Paul, we have the same scooter, do you know offhand where the fuses are located? This scooter has no power when you turn key, Id like to check
Chinese scooters have one glass 10 amp fuse by the battery.
@@LabCoatPaul Thanks paul, if that fuse is good and you turn the key and get no power and the battery is new, what else you think it could be, where should I start tracing? TY great channel
I have a X-pro 2023 can this be done on this scooter too ?
yes.
HI, I have a 150cc, it seems to start and idle fine, but after about 10min of riding and if you go open throttle, the bike seems to enter a lean or fuel starved condition, it will start to bog and then stall, wait 10secs, it starts up again, but then will sputter and bog then stall again, Ive replaced, carb,cdi,plug,battery,coil,vaccum petcock, fuel lines,,,same thing happens,,,HOWEVER, I noticed that from the gas tank(under the floor boards) to the petcock there are big bubbles of air many times in that line,,,,I am thinking that may be the issue, why would this be happening, and how could I fix it? TY for your video
you could check and see if it is vapor locking maybe
you found the problem:
the fuel hose right at the gas tank fitting needs tightning,it is picking up AIR right there, due to the suction;
@@josepeixoto3384 actually the fix was the pickup coil, when I replaced it all the issues went away
@@thedaydreamer7972 good to know that it can cause that kind of a misfire too, thanks
Vacuum lines are really cheap after you deleat the egr I always have a hard time starting it up unless you buy an EFI system
EGR has nothing to do with starting the scooter
This guy funny
How fork oil go in these
Check out this video: ua-cam.com/video/KWsQmxO5o3g/v-deo.html
What size hose is that??
In the video I used 3/16" and 1/4" hose. Look at the numbers on screen in the video when I install each hose.
My motor mounts are gone is it possible for a motor mount replacement video?
I don't have a motor mount video, but this might help: ua-cam.com/video/hxA2fOvkQT8/v-deo.html
"This is a Chinese scooter so the emissions system doesn't work anyway" FUNNY! - There are CA approved Chinese scooters but they are not the norm. I live in a state/county where we do not have emissions checks at all for any vehicle so I'm free to gut that stuff as I see fit.
Dove si trova la Batteria ?
In this scooter, the battery is in the seat compartment.
Why did you just not block off unused vacuum ports with caps? Also, why no one on UA-cam is using JB Weld to block the hole on the engine block, no one wants to wait for it to dry?
I have a ice bear trike 157qmj with a egr Air filter nipple. Or I think it's a pcv hoes connected to the air filter. Only problem is that where I live they don't have that kind of air filter with nipple on it. So I bought a air filter with out the nipple plug. My problem is , since my new air filter don't have a nipple to place the hoes that goes back to it what should I do? I don't know how to take the EGR system completely out so I have that hoes lose. Should I plug it or zip tight it to the frame n leave it out in the open. Can some one help!!!!
The PCV hose is connected to the air box so the engine can burn crankcase vapors instead of releasing them into the atmosphere. You can just drill a hole in the air box and push the hose in. Watch the video at 4:38
@@LabCoatPaul thank you so much. I feel way way better with your advice. Thank you.
I have a 96 taotao and I've replaced all hoses gas and vacuum my scooter will old a speed for a min then act like it ran out of gas I need help lol 😆
If it's running out of gas, there are a few things to check. If your gas tank is lower than the carburetor, you'll need to check the fuel pump. If the gas tank is higher than the carburetor, check the fuel petcock. Disconnect the fuel hose from the carburetor and put it in a cup. Crank the engine and make sure you get fuel.
It's also possible to get vapor lock in the gas tank. If your scooter dies after riding, open the gas cap and close it again. If it runs after that, you have a bad gas cap.
You could also have a dirty carburetor. Take the float bowl off and check your fuel inlet valve.
@@LabCoatPaul I've checked all those except the inlet value not sure what that is
@@Mizfitvidz The fuel inlet valve lets fuel into the carburetor. Check out this video: ua-cam.com/video/0m13eJrfwOw/v-deo.html
I enjoy watching your videos and I've helped me with a lot of things that I thought I would never be able to do. I was wondering if you could help me with an issue I'm having with the air box. I have a Rogue star 150cc and I can't seem to get the carburetor back in place .Some of the rubber portions have ripped off on the connection on the airbox while removing the old carburetor. Almost like a ring of rubber ripped off because of wear and tear. Consequently I can't seal it will on to the carburetor. Almost like it's too short now to even extend to attach the clamp to seal because of the ripped off ring a rubber. Do you have any advice or recommendations on how to seal the airbox to the carburetor that goes into the airbox?
Remove the air box from the scooter. You might be able to fix the air intake tube with some silicone sealer. Otherwise, find a new airbox online. Just do a search for Chinese scooter parts and you should be able to find an airbox that looks like yours. Install the carburetor first, then the air box.
Have you ever washed your scooter before lol
