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!
When it comes to replacing PVC hoses, it's important to consider the temperature limits and choose hoses that are suitable for your specific needs. PVC (Polyvinyl Chloride) hoses typically have temperature limitations that should be taken into account. Standard PVC hoses usually have a temperature range of around 0°C to 60°C (32°F to 140°F). These hoses are suitable for a wide range of applications, including water transfer, irrigation, and general-purpose use. However, they may not be suitable for high-temperature environments or applications where the temperature exceeds their limits. If you require PVC hoses that can handle higher temperatures, you may need to look for specialized variants. High-temperature PVC hoses are available in the market, and they are designed to withstand elevated temperatures. These hoses may have a temperature range of -10°C to 80°C (14°F to 176°F) or higher, depending on the specific product. When selecting PVC hoses, be sure to check the manufacturer's specifications and guidelines to ensure they meet your desired temperature requirements. It's also worth considering the intended application, pressure ratings, and any other specific needs you might have to ensure you choose the right type of PVC hose for your project. Additionally, keep in mind that if you're dealing with extremely high temperatures or require hoses for specialized applications, other materials such as silicone or reinforced rubber hoses might be more suitable. These materials offer higher temperature resistance and can handle more demanding conditions.
@@VirberelloScooterTips Thanks for your kindly respond to analyze my question! Actually I did forehead thermometer to detect scooter engine running idle mode in few month ago, I got scooter engine temperature around 90°C! Based on your suggestion, silicone hose characteristic is better than PVC hoses also it is able to match my demand, right!
Another question is, my SYM carburetor scooter over half year that engine does not working in Taiwan! After I 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 does not working to push gasoline via fuel filter out? Do you have some idea to help to fix my breakdown SYM scooter here, thanks!
@@hunterchung7070Based on the information you provided, here are a few suggestions to help diagnose and potentially fix the issue with your SYM carburetor scooter: Fuel system check: Since you mentioned that the fuel tank is not pushing gasoline through the fuel filter, it's essential to inspect the fuel system for any possible issues. Start by checking the fuel lines for blockages or leaks. Ensure that the fuel valve is open and that fuel is reaching the carburetor. If necessary, clean or replace the fuel filter and check the carburetor for any clogs or obstructions. Carburetor adjustment: If the fuel system seems to be functioning properly, you may need to adjust the carburetor. The carburetor controls the air-fuel mixture going into the engine, and an incorrect adjustment can prevent the engine from starting or running smoothly. Refer to your scooter's manual for the appropriate carburetor adjustment procedure, or consider taking it to a professional mechanic for a thorough inspection and adjustment. Ignition system check: While you mentioned that the spark plug has a flash, it's still worth verifying the overall condition of the ignition system. Check the spark plug wire for damage and ensure it is securely connected to both the spark plug and the ignition coil. If the spark plug is old or worn out, consider replacing it. Additionally, inspect the ignition coil and other ignition system components for any issues. Air filter inspection: A clogged or dirty air filter can restrict airflow to the engine and affect its performance. Remove the air filter and clean or replace it if necessary. Make sure there are no obstructions in the air intake system. Compression test: You mentioned that the engine cylinder pressure is 126psi, which seems reasonable. However, it's worth conducting a compression test to ensure the engine's overall health. Follow the proper procedure outlined in your scooter's manual to perform a compression test. If the compression readings are significantly low or uneven across cylinders, it may indicate an internal engine problem that requires further investigation

is it possible to install a new valve with the head pointing down? overturned? "ribaltata" in italian? Because it has got a screw that it's different from the new one
A gas scooter leaking fuel out of the air filter could be caused by a few different issues: Carburetor Problems: The carburetor is responsible for mixing air and fuel in the correct ratio before it enters the engine. If the carburetor is dirty, clogged, or damaged, it may cause the scooter to run too rich, which can lead to fuel leaking out of the air filter. Float Valve Issues: The float valve controls the flow of fuel into the carburetor. If the float valve is stuck in the open position, it can cause fuel to overflow into the carburetor and out of the air filter. Fuel Line Problems: A cracked or damaged fuel line can cause fuel to leak out of the air filter. Additionally, if the fuel line is kinked or clogged, it can restrict the flow of fuel to the carburetor, causing it to run too lean or too rich. Faulty Fuel Filter: If the fuel filter is dirty or clogged, it can restrict the flow of fuel to the carburetor, which can cause the scooter to run too lean or too rich.
Hello I think that placing a double filter will slow down the fuel flow going to the carburetor and that will effect performance at full throttle at speeds over 40 mph yes that petcock is universal if your scooter is having a vacuum system running on gravity fuel flow
Can you please do a video on how to change simple fuel line on a 50cc I'm a girl but I'm also a girl relative of the best mechanic that ever lived I got to establish my birthing absolutely right
Hello my friend I Will love to make that video but unfortunately I only have my scooter to make videos but I will keep that in mind to see what I can do 👍Thank you for watching my video
I just got my new valve. It doesn't have the top side for the vacuum line. Only the two sides for the carb and fuel line... did I get the wrong one? It just seems like it's a medium to turn it on and off. My problem was always having to create a vacuum. Was thinking this would help me avoid that. But again, there's only two sides and the on off switch. Also I have a 49cc scooter. Will the one you are using work on mine?
@@VirberelloScooterTips only two connections. It's screwed onto the opening at the bottom of the tank. It had a topside valve and a lower valve. I see that I just bought an on/off switch not the manual petcock...damn! It's OK. I was trying to figure out how to work around having to buy the right part. Because it's gonna take too long to get get here. It's in my cart on Amazon. I can't just fit a tube as a washer up there and connect it to the valve switch?
Hello Matthew the best way will be to place a Fuel Shut Off Valve like this amzn.to/3fl1n7h because if you like to travel at higher speed your petcock valve can not supply fuel on demand and the vacuum line that goes to your petcock you can close that with a 6mm screw or just make one hose that goes from your manifold to your carburetor diaphragm to bypass everything, Thank you for watching my video

Hello Scott there is a possibility that when you park your scooter the side of the petcock valve with the vacuum hose that connect to the manifold is leaking fuel inside of engine cylinder after the fuel goes inside pass between the wall and the rings of the pistons and goes inside the oil but that can also work if your fuel valve is not closing when you dont run the scooter and fuel leak in the carburetor and the carb overfill and leak fuel inside the motor what you can do is to replace the petcock valve or place a fuel Switch amzn.to/2Fqn9dx and go directly to the carb from the tank and when you do not use the scooter you close the switch and the vacuum hose that now you have at the petcock you put inside a 6mm bolt to close the hose .

I do have a question? I bought a brand new X-Pro 150 2022 BD150T-6 scooter. The first day it had no problems and engine ran smoothly and put 55 miles of break in time. Second day of riding it just ran out of fuel with a full tank. I let it sit for about 5 minutes and it fired up and ran about two miles smoothly and quit running again! I did this all the way home for about 7 miles. My shade tree mechanic skills are telling me there is a pinched fuel line somewhere or do you think the vacuum petcock could go bad the second day I rode it? Any help would be appreciated. Thanks, Carl
Hello make sure the screw at the carburetor drain is close look in front of the cvt cover lower front left side make sure the screw is tight somewhere your scooter is loosing fuel when you the motor is on
Hi Pat I bought an exact same model as you do and kinda same symptom happened on me! When its cold engine before cranking up I see full cup of fuel saturating the fuel filter and fuel supply goes well until several miles the cup goes empty and it looks like the percock doesn’t suck the fuel constantly and the bike engine shut off. It may happen again as you mentioned. I replaced 2 cabs and now it’s the time to test petcock though. Just give your some thoughts..
Good video brooo ♥️♥️♥️♥️ Question please I have gy6 and I use 20w50 oil for 3 years and temp not reach 38 at summer now ... Can I use oil 10w40 with no problem in engine 🙂

Hello Bennie that can be for many reason low tyre pressures, sticking choke , worn carburetor jets, a hole in the petrol tank , carburetor float not working properly
Hey question I ordered a new petcock pump for my scooter because the old one I would suck on the vacuum side and I wouldn’t get any suction from the fuel inlet side... is that a correct diagnosis? I also ordered a new carb because the Chinese one on it is non adjustable and needed cleaning and you can’t clean this type of Chinese one... please help I’m trying to learn more about scooter repair
Hello Joel petcock valve many times they get sticky and they do not let the fuel flow freely so sometime is good to change them or even better one day I will remove that petcock and place a shot off valve . Thank you for watching my video
virberello GY6 Scooter Tips thank you 🙏🏽 now that I have the new one I can definitely see that the diaphragm inside is stuck you can blow clean through the old one without any vacuum!! I love your video never stop it helps so many
Hi there, 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!
Hello my friend you should not have any air bubbles inside your fuel hose because the air will build up inside the carburetor and the flow of fuel will not be consistent so the motor will not run the right way try to find the air leak at the pump or you just need to tight a hose and try again. Thank you for watching my video
Hey Virberello I was riding yesterday and scooter bogged out on me and would not start. I removed the gas line from the petcock going to the carborator and no gas was coming out..i also put a new carb in...but...i didnt put gas filter back on..i was trail and error why scoot wud not start a week ago..( i was thinking it could possibly be the gas filter but it wasnt)...could just a few days of riding f( i probly put 45 50 miles on it...with no gas filter clog up my jets or is it the petcock? i hope i dont have to order another carb..
Hello Luke no you do not have to order another cab there is a possibility that if you run the scooter without the filter the jets get dirty sometime the fuel tank builds up little dirt on the lower side
But i cant get to the jets and clean it because there are rivets on the float bowl and it hard to get to the jets to clean..still a bit confused here...
Hi great video I have a keeway tx 125s when it's cold the bike runs fine but as soon as the bike gets warm it starts bogging and slowing down, I've had a new spark plug new carburettor put on and the valve clearance done but still the same problem do you have any ideas or advice please
Hello Richard many things can produce a problem like this dirty carburetor, bad electronic enricher or bad stator that when the copper coil get hot is not producing good current the fist thing I will test ac voltage of the stator with a multimeter when scooter is on and when the scooter is cold I will check for compression with a compression tester
@@VirberelloScooterTips thanks for reply I've put it in the bike garage now so hopefully find the problem they have told me my compression is at 110 and should be at 150 so hopefully they can see if that works
Hi I have a Lexmoto Tornado 125 it will not start up at all it’s got compression got spark but when I spray carb cleaner into air box inlet it starts up what can it be? Could it be my fuel pump that is the problem?
@@VirberelloScooterTips okay, also am I supposed to have an actual petcock valve that can be turned on or off ?? I am being told I should have one but I cannot find it , or an off switch for the fuel
@@VirberelloScooterTips also I went and got a new spark plug, I put it in and have it out of the motor in the coil wire , I try and kick start it and I do not see a spark at all? What is my next step?
@@VirberelloScooterTips the spark plug cap?? Is that on the coil that’s connected to the plug?? Or you mean the medal piece that was screwed over the end
There are several ways an overflow valve on a gas scooter can fail: Stuck closed: If the overflow valve becomes stuck in the closed position, it may prevent the excess pressure from escaping. This can lead to an increase in pressure within the fuel system, potentially causing damage to fuel lines. Stuck open: Conversely, if the overflow valve gets stuck in the open position, it can cause a constant release of fuel or gas vapors from the system. This can result in poor fuel efficiency, reduced engine performance, and possibly create a safety hazard due to fuel leakage. Contamination or blockage: Sometimes, debris, dirt, or other contaminants can enter the overflow valve, causing it to become stuck or obstructed. This can affect the valve's ability to function properly, resulting in incorrect pressure regulation. Wear and tear: Like any mechanical component, the overflow valve can wear out over time. Frequent exposure to vibrations, temperature changes, and fuel can cause the valve's internals to deteriorate, leading to failure. It's important to note that a failed or malfunctioning overflow valve can potentially lead to dangerous situations, such as fuel leaks, engine damage, or fire hazards. If you suspect an issue with the overflow valve or experience any abnormal behavior with your gas scooter, it is best to have it inspected and repaired by a qualified technician to ensure proper functioning and safety. Regular maintenance and checks can also help prevent potential failures and ensure the longevity of your gas scooter.

I just want to learn and i want to see what your professional advice and experience can do to take my beat up scooter into something beautiful, with as much performance modifications as I can afford to spend on this little guy, my guess is hopefully by the end of this year if your up to helping me with your content and advice make smart decisions about what parts i need to tend to first, tools, and how to do things, heck even speakers and some custom fabrication parts for the body to make it look good and be comfortable for my gf if she wants to go somewhere on it:)
I do not know anything about engines .im out of work so i can’t afford to take it to a shop I need my scooter to find work I’ve been trying to fix it myself you’re videos have helped so far but I’m getting gas in my oil y and how do I get it fixed please someone help me ?
Hello Scott there is a possibility that when you park your scooter the side of the petcock valve with the vacuum hose that connect to the manifold is leaking fuel inside of engine cylinder after the fuel goes inside pass between the wall and the rings of the pistons and goes inside the oil but that can also work if your fuel valve is not closing when you dont run the scooter and fuel leak in the carburetor and the carb overfill and leak fuel inside the motor what you can do is to replace the petcock valve or place a fuel Switch amzn.to/2Fqn9dx and go directly to the carb from the tank and when you do not use the scooter you close the switch and the vacuum hose that now you have at the petcock you put inside a 6mm bolt to close the hose . Thank you for watching my video Scoot and if you need any help feel free to contact me anytime also visit Chinese Project Scooters on facebook there you can find lots of scooters owners with lots of experience
virberello GY6 Scooter Tips thank you so much someone told me it was the head gasket that needed to be changed so I’m glad it’s not that .yes it has been sitting for a while and the petcock is bad and I replaced it with a shut off valve and it was getting to much fuel it sounds like from what you say .it wouldn’t even start I had a problem with figuring out my vac and fuel lines .then I think I had them right because it started but didn’t stay running I checked my oil and noticed a lot of pressure and the oil had gas in it but I’m not going to mess with the shut off valve I’m going to get another petcock .sorry for rambling thank you so much you are awesome thanks again
@@VirberelloScooterTips I’m sorry sir I am still having trouble with the scooter fuel and vac I can at least get it running but won’t stay running or fuel comes out one of the spouts or pressure builds up in the engine and when I take the oil stick out there’s pressure but I don’t smell gas maybe a little but I think that’s Frome before I have a hose nozzle on the manna fold one near it on the hose that connects to the carb from the manna fold another hose nozzle on left upper side of carb one on the right side by the idle then one on the upper left which is the fuel intake and two under that at the bottom back of carb and I have a shut off valve instead of a petcock please can some buddy send me a detailed diagram what hose goes where and what gets capped and what gets left for drain hose I finally got a job two weeks ago but I’m riding a bicycle and just looking at my scooter decaying again pleas help me I’m not a mechanic thank you
@@scottlurachy240 Hello if you have a GY6 150cc and your scooter is not stay on I think that could be a crack on the rubber of the manifold or you need to do a valve adjustment ua-cam.com/video/csH2RGvXegI/v-deo.html but the best think you can do join the chinese project scooter group on facebook and you can make a live video of the problem so everyone can see the problem and we can help you
I do have a question? I bought a brand new X-Pro 150 2022 BD150T-6 scooter. The first day it had no problems and engine ran smoothly and put 55 miles of break in time. Second day of riding it just ran out of fuel with a full tank. I let it sit for about 5 minutes and it fired up and ran about two miles smoothly and quit running again! I did this all the way home for about 7 miles. My shade tree mechanic skills are telling me there is a pinched fuel line somewhere or do you think the vacuum petcock could go bad the second day I rode it? Any help would be appreciated. Thanks, Carl
Hello make sure the screw at the carburetor drain is close look in front of the cvt cover lower front left side make sure the screw is tight somewhere your scooter is loosing fuel when you the motor is on
Hi Pat I bought an exact same model as you do and kinda same symptom happened on me! When its cold engine before cranking up I see full cup of fuel saturating the fuel filter and fuel supply goes well until several miles the cup goes empty and it looks like the percock doesn’t suck the fuel constantly and the bike engine shut off. It may happen again as you mentioned. I replaced 2 cabs and now it’s the time to test petcock though. Just give your some thoughts..
Good video brooo ♥️♥️♥️♥️
Question please I have gy6 and I use 20w50 oil for 3 years and temp not reach 38 at summer now ... Can I use oil 10w40 with no problem in engine 🙂
Hello my friend yes 10w40 is my favorite juice Thank you for watching my video and stay safe
@@VirberelloScooterTips
Oki 10w40 oil after using 20w50 for 3 years doesn't affect my engine bad yeah?
@@islamayman5927 No is going to be good
@@VirberelloScooterTips
Thank you very much and I put that oil soon and give you my opinion 🙂♥️
@@VirberelloScooterTips
hi sir i put 10w40 oil and the engine after 25 km become high noise speacially at firts 2:3 km at morning and the vibration of engine increase 15% .
what your opinion of that keep with it or return use 20w50 ?
Where were you the past ten years lol?
Hello my friend thank you for watching my video
Hi how are you doing please help why my scooter jusing to much petrol
Hello Bennie that can be for many reason low tyre pressures, sticking choke , worn carburetor jets, a hole in the petrol tank , carburetor float not working properly
Hey question I ordered a new petcock pump for my scooter because the old one I would suck on the vacuum side and I wouldn’t get any suction from the fuel inlet side... is that a correct diagnosis? I also ordered a new carb because the Chinese one on it is non adjustable and needed cleaning and you can’t clean this type of Chinese one... please help I’m trying to learn more about scooter repair
Hello Joel petcock valve many times they get sticky and they do not let the fuel flow freely so sometime is good to change them or even better one day I will remove that petcock and place a shot off valve . Thank you for watching my video
virberello GY6 Scooter Tips thank you 🙏🏽 now that I have the new one I can definitely see that the diaphragm inside is stuck you can blow clean through the old one without any vacuum!! I love your video never stop it helps so many
Great, thanks. Where would you re-route the vacuum line after installing a manual switch/lever?
Hello if you place a manual switch I just plug the vacuum lime hose with a 6 mm screw or a hose plug
@@VirberelloScooterTips great info mate, many thanks. I like simple fixes 👍
Hi there, 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!
Hello my friend you should not have any air bubbles inside your fuel hose because the air will build up inside the carburetor and the flow of fuel will not be consistent so the motor will not run the right way try to find the air leak at the pump or you just need to tight a hose and try again. Thank you for watching my video
@@VirberelloScooterTips thank you my friend !!!!
@@VirberelloScooterTips hello Mr viborello. Do you have an email address where I can talk with you more about my GY6 150cc?

Hey Virberello
I was riding yesterday and scooter bogged out on me and would not start. I removed the gas line from the petcock going to the carborator and no gas was coming out..i also put a new carb in...but...i didnt put gas filter back on..i was trail and error why scoot wud not start a week ago..( i was thinking it could possibly be the gas filter but it wasnt)...could just a few days of riding f( i probly put 45 50 miles on it...with no gas filter clog up my jets or is it the petcock? i hope i dont have to order another carb..
Hello Luke no you do not have to order another cab there is a possibility that if you run the scooter without the filter the jets get dirty sometime the fuel tank builds up little dirt on the lower side
But i cant get to the jets and clean it because there are rivets on the float bowl and it hard to get to the jets to clean..still a bit confused here...
Hi great video I have a keeway tx 125s when it's cold the bike runs fine but as soon as the bike gets warm it starts bogging and slowing down, I've had a new spark plug new carburettor put on and the valve clearance done but still the same problem do you have any ideas or advice please
Hello Richard many things can produce a problem like this dirty carburetor, bad electronic enricher or bad stator that when the copper coil get hot is not producing good current the fist thing I will test ac voltage of the stator with a multimeter when scooter is on and when the scooter is cold I will check for compression with a compression tester
@@VirberelloScooterTips thanks for reply I've put it in the bike garage now so hopefully find the problem they have told me my compression is at 110 and should be at 150 so hopefully they can see if that works
Thank you,where are you in Florida
Hello Marcello WPB in Florida
Hi I have a Lexmoto Tornado 125 it will not start up at all it’s got compression got spark but when I spray carb cleaner into air box inlet it starts up what can it be? Could it be my fuel pump that is the problem?
Hello James I think that is a dirty carburetor jet but can be a fuel valve too anyway look like the fuel is not going in the engine at this moment
I have a question.. if you put a after market exhaust on a 50cc four stroke do I need to put a after market carb on it too? Or stock is fine?
Hello you can keep the stock carburetor but if you change the air filter you should up jet the carburetor
@@VirberelloScooterTips thank you for the help
Can bad fuel petcock affect badly the idle speed RPM ?? Thanks again .
Hello yes if the fuel does not flow free can effect the idle or the rpm
@@VirberelloScooterTips thank you very much ..my best regards from Egypt.🤗🤗🤗
Hello, so on the fuel pump , I should be able to blow air through the out and not through the in right ??
Hello my friend yes you are correct you should be able to blow air through the out and not through the in
@@VirberelloScooterTips okay, also am I supposed to have an actual petcock valve that can be turned on or off ?? I am being told I should have one but I cannot find it , or an off switch for the fuel
@@VirberelloScooterTips also I went and got a new spark plug, I put it in and have it out of the motor in the coil wire , I try and kick start it and I do not see a spark at all? What is my next step?
@@VirberelloScooterTips the spark plug cap?? Is that on the coil that’s connected to the plug?? Or you mean the medal piece that was screwed over the end
@@VirberelloScooterTips alright yea the coil I have has a boot on it
That's exactly what's going on with my bike.

What size are the hoses?
Hello Brad the hose is 6mm . Thank you for watching my video
Does this part break often?
Hello no does't break to often but after 8 to 10k miles it start to leak a little beat.
Thank you for watching my video
There is a float valve inside the carburetor no over flow to engine.
There are several ways an overflow valve on a gas scooter can fail:
Stuck closed: If the overflow valve becomes stuck in the closed position, it may prevent the excess pressure from escaping. This can lead to an increase in pressure within the fuel system, potentially causing damage to fuel lines.
Stuck open: Conversely, if the overflow valve gets stuck in the open position, it can cause a constant release of fuel or gas vapors from the system. This can result in poor fuel efficiency, reduced engine performance, and possibly create a safety hazard due to fuel leakage.
Contamination or blockage: Sometimes, debris, dirt, or other contaminants can enter the overflow valve, causing it to become stuck or obstructed. This can affect the valve's ability to function properly, resulting in incorrect pressure regulation.
Wear and tear: Like any mechanical component, the overflow valve can wear out over time. Frequent exposure to vibrations, temperature changes, and fuel can cause the valve's internals to deteriorate, leading to failure.
It's important to note that a failed or malfunctioning overflow valve can potentially lead to dangerous situations, such as fuel leaks, engine damage, or fire hazards. If you suspect an issue with the overflow valve or experience any abnormal behavior with your gas scooter, it is best to have it inspected and repaired by a qualified technician to ensure proper functioning and safety. Regular maintenance and checks can also help prevent potential failures and ensure the longevity of your gas scooter.
mine screws on to fuel tank
