You guys are so kind to have made a video based off of someone's question on another video.. and I learned something new! So cool bc my son's scooter has a very low idle. THANK YOU!!
All very new to the bike world and after spending over £500 and still having the same problems this video has solved the problem .. no idea why the garage didn't pick this up but I've one happy son now .. thank you 👍
You guys are great I just buy a new scooter 2 week ago then start turn off but I learned today from you and am not going see mechanic but I will do it myself. Thanks for the video
If this works you are literally saving me. I have been to four mechanics already for this problem and they all say that there isn't anything wrong and that the problem is with how I'm stopping.... I will try this tonight!! Thank you!
when the wheel spins on idle tho its not enough to move you but it does mean that the clutch is in contact with the bell and that means wear. what i do is I run the engine cold, and when the enricher stops, it drops in a very low rpm, that's when i adjust it low enough that it doesn't stall after the enricher turns off.
Yes sir. It's a 150. I couldn't reach the screw,nor could I see if it was a torx, Phillips, or hex. So I took it to the local motorcycle shop in visalia ca. The guy said it was a 2.5mm hex. So he gave it a turn or two. Brought up the idle and away I went. (He didn't even charge me) I rode around town like i had been doing before. And after over an hour or so of riding in city traffic, making u turns and stopping at intersections.. The bike give me no more problems. 🤙🏾
Hey man just bumped into this I appreciate it so much I had to keep my hand on the throttle for a good minute getting home and doing this helped my scooter stay on well appreciated boss💪🏽🤞🏽
Ive got a 250cc scooter the other day I was riding it and it felt like it was running out of gas but it picked up started running but it doesn't have the acceleration like it did before that ordeal
Mine has this problem won’t idle and drives nice when I’m on it but soon as I let off the revs bogs out .. my bike does not have an idle screw so what then
Does it have a carburetor? Sounds like it may be fuel injected? I'd try to get it into a shop nearby to see what's going on. Sorry we can't be more help with this one!
Yes, if your idle is indeed too high, this would help. However, other issues like a broken clutch, clutch spring, etc. could also cause the rear wheel to "stay engaged" and keep moving as well. But start by adjusting the idle and see if that helps, especially if your idle speed is revving very high.
hi, i didnt use my scooter this winter, and now, when its on the stand its starts but when i leave it down it will just cut out, i kept it running on the stand a few minutes to warm up but then it was doing the same, do you know what it could be??
Is a vacuum line or fuel line getting pinched by something when it comes off the center stand? I would check your lines to make sure they aren't caught up in a shock or something.
@@NewScooters4Less even if the scooter is not running and is not on stand it dosent start, i was thinking is something to do with the wheal being in the ground and not being able to spin..
@@sarahmulqueen9014 I'm not sure I understand. If it's starting and the wheel won't spin and feels stuck, you could have a broken clutch spring or another transmission problem.
@@NewScooters4Less sorry about that english is my second language, the wheal is spinning when is on the stand, but when i leave it down the engine just stops, and its a 125 cc twist and go there's no clutch, its ok nevermind i think i need a mechanic to check it properly, thank you
@@sarahmulqueen9014 Not a problem. If the wheel is spinning when it is on the stand, the idle may be turned up a tad bit high. There is a clutch, but it's a CVT transmission (meaning it's automatic, aka - twist and go). I would definitely get it into a shop when you can! Good luck!
what about the opposite. so mine works well cold, picks up very quickly. but after 2 mins then the bike bogs , i then have to fether the throttle up to it gets to a higher or around 20mph speed then works fine. please get back to me if you get yhe chance. many thanks, rich
I have the exact same problem with my scooter, except mine has fuel injection, not a carburetor. What should I do with it? And it's not just when it's cold, it happens all the time for me. I check the engine, and don't think that there is an idle adj screw like the one in this video.
My issue: Where you have it on the center stand it idles fine, but the back wheel is moving. When I hit the rear brake, then it dies out. It's like the power from the motor never disengages from the back wheel. Thoughts?
Is your concern that the back wheel is moving when it is on the center stand? (As long as the scooter doesn't feel like it is pushing you when it is on the ground,) it's ok for the back wheel to move a little bit when on the center stand because when it is on the ground, it won't. Does that make sense? (Think about it like a car... When you take your foot off the brake in a car and it is in Drive, it wants to creep forward. Your foot on the brake is keeping it from moving forward. It's similar with a scooter... when your scooter is off the center stand and on the ground, the brake and your body weight keep the scooter from moving forward (unless of course the idle is too too high and the scooter feels like it is pushing your forward when idling)). Hope that helps!
Oh it’s definitely pushing me. It jerks the whole scooter with each stroke of the motor until it dies. I’ve adjusted the carb with the same symptoms. That’s why I wonder if it’s the transmission assembly
@@93paxon I'm almost willing to bet it is 100%! Sounds like the clutch may still be engaged when you are at a stop. Probably a popped spring on the clutch assembly! Definitely check that out!
Thks four your video I have a Peugeot V-Clic 50cc 4T from 2012 is same carburetor when I start up the idle is keep up and down up again and down is any reason ??? Thank you very much Jersey uk ❤
So.i did this and found it still wasn't staying on I went to the throttle cable on the carb and now it revs wayyyyy to high and if I even move the screw it dies down if I adjust it ... What am I doing wrong or what do I need to adjust instead the cable back more slack or tight ? And loosen the bold more ? I'm at a loss going 30 mph with 100 cc
You saved my life just got a 2020 beast grom bike just yesterday and it started dying out on me ...mind you I. Don't know anything about bikes so I started to freak out 😂😂😂 but I came across your video and Wallaa just like that it stayed on
I jus bought a new scooter yesterday. Engine bogs down and cuts out all the time, especially when i indicate or have lights on. Freakin annoying. Jus soent a grand on a faulty bike on gumtree, feels bad man.
WIth it being that new, I'd take it back where you bought it. If it bogs down when you use indicators, etc. then it's probably an electrical problem. I would start diagnosing by checking all your ground wires first to make sure none of them are broken.
HELLO PLZ HELP ! when i start mine , it doesnt a actually keep that rev ... in about 4 seconds it allways die out when stoped ... SO can it be screwing it up a little when its OFF then see if it fixed ??? and is it propubly coz the battery thats dying? or a some dirty in the carb???? thnx a lot
Fairly new apriliia storm scooter. Engines dies when throttle is pulled. But doesnot have any problem once it gets warmed up. Will this solve the issue. It happens everyday when trying to start the scooter.
Check the fuel-air mixture. Some scooters have a screw to adjust. You may be able to adjust the needle in the carb or you may be able to adjust how much air is being sucked into the air filter. Sounds like an adjustment there will help.
Hi thank you for your video I have a Piaggio Zip 50 2T when I drive and give a full acceleration is luck like is cutting down you don’t now way please thank you
So we changed the idle but our issue is it’ll start on the stand but struggles on the ground. (Resistance on the wheel) we’re thinking maybe something with the clutch? It dies anytime there’s resistance on the rear wheel ie body weight, brakes
Yes. You could have a broken spring on the clutch or another similar issue. I would definitely pull the transmission casing off and look at that clutch and transmission.
@@NewScooters4Less After I sent this I pulled the cover off and found the issues. The ceramic pads for the clutch were all broken and pieces were everywhere. Ordered a new clutch and transmission assembly that I will be putting on later today!
Does it have a carburetor? Can you make this adjustment made in the video? Also check for vacuum leaks (cracks in the vacuum lines, crack in the intake manifold, etc.)
So what having a similar problem but not when stopping so basically everything all fine but when I turn my steering all the way or even half way to the left it cuts the moped off what would be making it doe that as I use my moped to go to my little brother grave from time to time only way I I’ve to get there and to check on him
Check your ignition wiring. When you turn the steering, it is probably pulling on the wiring and causing the ignition and/or kill switch to function which is cutting it off. I'd bet it is something in that wiring up front by the steering. Also check the wiring for any cuts, tears, etc. in case something is rubbing the frame and shorting out (but my guess is that you would be popping fuses if that was happening).
@ thank u so much new to this stuff are do all the checks u just told me to do in abit Is only a old Yamaha vitty so shouldn’t be that hard if is what your saying it is thank u again for the help
For me? It seem to be a different problem.. As if the Starter clutch or drive clutch is sticking when I hit the brake. My scoot stops as soon as the wheel stops?
Have you opened the transmission casing and looked inside? Maybe a broken spring in there on the clutch or something. Should be able to pop off the case and take a look around.
Hi please I have tried adjusting like you sai but is not working for my kymco scooter is either I higher it if I try lowering anytime my hands let go off the gas then it automatically go off what could be the solution
You probably have a different issue. My guess would be a vacuum leak somewhere. Check your vacuum lines, intake manifold, and make sure that there are no cracks where air could be escaping. Thanks!
When I turned this screw on mine, I know I used to be able to make it so my idle rpm was high enough to get my wheel turning, but lately with the screw turned up completely, my idle is only about 1200 rpm, which is nearly enough to keep the scooter running, but sometimes not quite.
I have an opposite case. The idle is slightly high and my scooter is pushing forward in idle. So I tried adjusting that screw by unscrewing it as far as it could. But that's not bringing down the rev. What's the problem?
Is your throttle cable too short? Did you recently replace that? You should be able to adjust the cable some too at the throttle handle and on the carb. It could be pulling to much on the carb (giving it too much gas)
I have a brand new scooter and it dies as well at an idle or coming to a stop. We have adjusted the throtal and that doesn't help it. We have had nothing but issues from the get go. The automatic electric choke was burning out, magneto was not gapped properly, the company we purchased it from sent us a new carborator and everything. Do you have any idea what we should check before my boyfriend throws it in a ditch somewhere?
@@NewScooters4Less it's a VIP future champion. We finally figured it out though the valves needed to be adjusted. Now it works great. Funny but he actually got pulled over for going 45 on it when top speed with out a motorcycle license is 30😂
Hi, I have a concern in my scooter. Every time I slow down to turn or ride across a hump on a road, my sccoter will suddenly have a slight burst in speed. Is there any fix to this? I tried adjusting the idle speed but it's still doing the same speed bursting
Hmmmm... maybe a vacuum / air problem. Check your vacuum lines to make sure they aren't getting pinched by a shock or something when you turn. Also make sure none of the lines are interfering with your throttle cable on your carburetor.
Please help, I'm not getting any gas to stay into the carburetor, in order to fuel the motor . have tried another carb as well. Does the same thing..., please reply..,
If you aren't getting fuel to the carburetor, then you may have an issue in the vacuum system or fuel pump. Make sure there are no cracks in your vacuum lines and then replace the fuel petcock that attaches the fuel tank to the fuel lines and filter. It could be faulty.
So today I’m going to buy myself a gilera runner 180 vx witch is the 4stroke version the bike starts up fine and rides nice but once I come to a stop it dies out but will start back up and go again also the bike seems to back fire and crackle and pop I was thinking if not the idle maybe I should try clean or change spark plug and old oil?
Probably fuel and air mixture is off. I don't know anything about that bike, but I would look at spark plug, carb, air filter, vacuum lines and make sure everything is good there.
You have a different problem. Could be a vacuum leak / issue. Could be something internal with the carb. Could be an airflow problem. Could possibly be electrical too. Sorry! May need to have someone look at it :(
What if I do this and it doesn’t work, when I higher the acceleration the wheels move to much and when I lower it just sounds like it’s going to die again, there’s no in between with mine, maybe battery ?
I have italika motor D125 in any weather when i turn on the scooter the battery makes a sound and wont turn on,so i need to kick start the scooter what seems to be the problem??
Does the battery work well in the warm weather? Could be cold-cranking amps in the cold. Could be tight valves and need an adjustment. Could be a variety of things, but a valve adjustment is probably what I would look at first.
Hi mate, I have a Peugeot vivacity 9/02 can not get started, have got spark and fuiel, can not find how to check valves or were the cover is, it was running 2 year’s ago but would conk out after running awhile, now trying to use it again, can you help, I’m thinking it may have sticking valves?? Regards Chris
I'd assume it's carburetor related, especially if it's been sitting that long. I am not familiar with that scooter though, so I would recommend getting it into a shop close to you. Thank you!
i did this and still some times doesn't really work. i have this issue and when i try to elektrik start it i can hear the motor that wants to turn up but it doesn't wanna start some times i gotta keep give it more gas to be able to start do you may know what i can do to this?
@@NewScooters4Less I do and i'll go tomorrow to the dealership garage to try and fix it. i think it's the carb that is the issue because the motor doesn't wanna keep spinning when im trying to let go of the throttle
@@NewScooters4Less I do have a question tho.. i have a 17mm carburetor and i want to buy a 19mm one. would my scooter have a higher performance and more power?
Thank you, this fixed my problem! Interestingly enough, Honda Metropolitans have a tiny hole in the maintenance lid specifically for access to that screw!
I have tightened this adjustment screw so much that I can not go further. However, the engine still dies out when idle. Can you please give me some hints to solve the problem?
It could be a few things... It could be a bad carburetor, issues with the jets in the carb, or something like a vacuum leak. What kind of scooter is it? You might want to replace the carburetor all together. Some are cheap enough to where it makes sense to do that. Good luck!
@@e-wave8247 Email our service department a picture of your scooter at service@NS4L.com and they can email you the cost of a carburetor that would work. I would replace the carb and clean out the fuel system. Hopefully that will do the trick for you. If you have a local shop, I'd probably get it in there if possible.
I just replaced the battery in my Vespa 150 after a long time in storage and it still stalls out after starting right up if I let it idle. I hope this is the fix. About to go try.
Yay! it worked. I am not driving it as it is not registered or insured but it ran idle long enough for me to go get my mail and more do it is ready for sale.
Ok here we go i just replaced my carb and it wont electric start or kick will come on if i twist throttle but it wont stay running to adjust idle? I have to twist it alot to make it rev..then heres a another problem ive tried a bunch of times for it to start with my electric start now it wont make the click noise but a diff noise now??? Im worried i broke it..makes like a zooommmm noise when i push the electric start in im so sick of scooters.. can you please help me ive also check my hoses to make sure there good after replacing the carb..
Sounds like the starter motor is just spinning or the starter clutch gear isn't grabbing. Could have come unaligned in the transmission. I'd get it to a shop man. Sorry!
hi my tgb cuts out as soon as i let go of a brake lever doesnt matter which one,it starts up and runs fine untill i let go of brake ,ive disconnected each brake switch in turn but still does it,any ideas as im running out of things to try.
it does run you can ride it up the road as long as you have the brake pulled in enough to not close the switch,i was wondering if it could be the rear light as ive got it fitted to the rear box and not the frame,so maybe its because the rear light isnt earthed to the frame,what do you think could that cause it to die when brake released,not earthing properly
@@scooterjd So you think it is shorting out somewhere? Maybe. I'd really need to have this scooter in front of me to properly diagnose. Sorry I can't help!
I have a 4 stroke scooter and when I start it everything is going alright but after 5 or 6 minute everytime i'm going to stop at a stop sign, my scooter turn off what's the probleme since I don't have a idle screw?
What size engine? 50cc? What brand of scooter is it? Does it start right back up or are you having trouble restarting it when it cuts out? Does your gas gauge, blinkers or anything electrical give out too or do you still have electrical power? Give me some more info please.

I need some help with my Lance 125 Cabo it keeps spitting out oil water and gas from the little valve underneath that unscrews it stalls and then I have to go down there and tighten that little screw for it to start and keep running now it's done this today alone like 5 times what's a quick fix for can you help
No quick fix. Sounds like there is water in the system that is causing issues. Is the water in the oil or the gas? Sounds like it is in the gas if it is coming out of the carburetor. I would remove and clean the carburetor, replace the fuel lines and fuel filter, and drain all the watery fuel out of the fuel tank... try the tank out and then put it all back together with high-octane fuel back in the tank. Gotta get that water out of the system.
@@Marct2626 You run through 2 tanks daily?! How far do you drive this thing? You may have a totally different issue going on. I would get it to a shop. Sorry!
I adjusted my scoot was stalling out acting up ran carb fuel cleaner and adjusted card now it doesnt stall but i can tellbits running rich gas smell and it goes through gas quick any ideas
You adjusted it by turning up the idle? I would dive into other areas of the scooter. Check for vacuum leaks, cracks in fuel / air system, clean/replace air filter, etc. Sounds like some fine tuning is in need. Have your replaced the spark plug? Pull the plug and see what color it is.
I’ve tried this on my 125cc moped and it didn’t work as good so I cleaned the carb to see if that worked still didn’t work it’s a 2022 plate so I’m not sure it also loose power
Hello sir what about when I reduce speed and the moped shuts off ? Is that normal ? I just bought it new and started riding it today thank you in advance
@@NewScooters4Less Factory recommended idle for Ruckus is 2,000 rpm +/- 100. Turns out I was losing compression because the service tech didn't seat spark plug all the way 😒
I had that problem, to solve it I set the air/fuel mixture screw 1-1/2 turns out and then the idel at 1900rpm when cold, after warmup rpm is at 1900~2300 problem solved.
Must be nice that this solved everyone else's problem with it. Mine however still stalled anytime I hit the back break whether I tightened or loosened it so what's the next reason it could be doing this.
Check your vacuum lines that run from the intake manifold to the fuel petcock and make sure there isn't a crack in them. Also make sure there isn't a crack in the intake manifold spacer that goes between the intake manifold and the head of the motor. Could be a crack somewhere.
Mine idles high at a cold start and then after awhile slowly dies down until it turns off this is without touching the throttle but if I touch the throttle I can keep it does a misfire little bit and I'm thinking that's a spark plug issue but I'm not sure what's your guy's is your adVice
Depending on what kind of scooter it is, it probably has an electric choke attached to the carburetor and that is why it slows down after it has been running. Is it only doing the little 'misfire' after you first start it? May want to give the scoot a couple minutes to warm up. If it is misfiring while all the time, then you could have a spark plug issue, but it could be a few different things. I'm not sure where you live, but maybe just let the scooter warm up for a few minutes before going and see if that helps.
@@NewScooters4Less I think so, if I keep the throttle open it won't stall, it doesn't seem to be under power, the bike moves as fast as a want it to. I have put fuel cleaner tho it to make sure nothing is blocked to much or dirty, about to fill it back up.
@@MrStitty26 Is it bogging and dying or is it just shutting off while driving? It could be losing spark while driving. May not be the spark plug, but could be coil, cdi, stator, etc.
@@NewScooters4Less it will only stall on idle so at light or when a have stopped, when i keep the throttle open it run great, one thing that dose happen is when i take of the accelerator it sounds like a bag off popcorn in the micro wave. also had a look today and noticed that there wasn't a cdi unit under the seat but the connector is there for it, but id imagine it wouldn't run at all without one. dose have an ecu under the tank as well.
Like while going full throttle and driving, it will cut out and die? Probably electrical. Check/replace your coil and CDI... Sounds like you could be losing spark when the unit gets hot.
so, this happened after i went over a huge pothole. engine has not been running well since. the engine dies every time i stop while warmed up, and choke is extremely high when cold. throttle is also very sluggish when i try to give it gas from a standstill while warmed up. i suspect something like a hose came loose, but have not been able to find the problem yet
I'd bet the same thing. Check to ensure that your intake manifold (between the engine and the carburetor) is tight and not loose or cracked. You could have a vacuum leak somewhere. Also check to make sure that the air box that attaches to the other side of the carburetor didn't pop off. Make sure it is nice and snug on the carburetor. Make sense?
@@NewScooters4Less i checked the vacuum lines and intake manifold. No problems. I also discovered another thing. The scooter works completely fine, every time i take it out of my basement, as if nothing is wrong. Although if I leave it outside in the winter weather and start it cold, that's when the problem occurs. Same problem, it idles high when it's cold, and sputters/bogs more and more as it warms up. Dies completely after driving for a minute, (especially when releasing the throttle) and won't start again until cold. There is spark, and the spark plug is brand new. After it died on me i removed the spark plug and inspected it. It was a little black, not too much, which usually is a sign of a rich mixture, but no other signs of it, such as visible exhaust smoke and rotten egg smell. (And as i mentioned runs perfectly when stored inside) I checked the valve clearances and it was 0.05mm intake and 0.08mm on the exhaust. Something seems to be malfunctioning when it has been sitting in the cold weather.
@@thatshot-ey8kh Scooters HATE the cold weather. Especially when it is carbureted and not fuel injected. Our dealership is in Florida and it is even a struggle here. They are going to be difficult to start in cold weather. Once you get it started, you want it to warm up for at least 5 - 10 minutes before riding. Once the motor is nice and warm, it will usually be fine. The carburetors have an automatic choke to help with this problem (which is why it starts off idling high). When the motor warms up, the automatic choke cuts off. Just sounds like your scooter (like most) is finicky with the cold weather.
@@NewScooters4Less oh right, forgot to mention that i do let it warm up, but when i do, it idles increasingly faster and faster, close to spinning the back wheel. After a minute or two, the idle plummets and the engine dies. It starts up again but not without throttle. The throttle is very hesitant and unresponsive, no matter how much i give it. It can drive for about a minute, until the bogging gets to the point where the engine just stalls regardless if i'm stationary or driving, or giving it throttle or not. I am certain that there is something wrong with it, because last year it would stay outside for eight hours while i'm at school in -5 degrees celsius compared to the 8 degrees now, but started and drove flawlessly back then. -it gets spark, fuel and air. -it has good compression -the problem only occurs after sitting outside for some time in the cold weather. -drives flawlessly if stored inside -it has 4634 km on it Maybe it's something electrical? Like the enricher?
@@thatshot-ey8kh Have you adjusted the valves on this machine since you've had it? You may want to try that. Besides that, I'm not sure how much help I can be. What I can say is that my experience scooters is that they are super finicky in extremely cold weather. Here in Gainesville, if it gets below 40 degrees F, the number of calls we receive related to scooters not starting or working properly goes way up. Best wishes with it my friend.
My scooter doesn’t want to start well when the engine is cold. Is there anyway to fix this? The scooter will start but it doesn’t feel like it’s fully started. I try to give it gas and it dies. I have to slowly give it gas for it to actually start up, if I give it to much gas it dies. How can I fix this?
I have a similar issue except that the idle on my scooter increases after lowering it . I’ll lower the idle so that the scooter doesn’t pull forward but once I give it throttle the idle revs higher and stays there along with the back wheel constantly turning. I have to constantly adjust the idle lower and it’s super annoying. Any suggestions as to what to do or how to fix it? What could be the cause? Thanks!
@@jarodhuber2687 The throttle isn't getting stuck open some how, right? Also, check the vacuum lines, intake manifold, and intake manifold spacer (between the manifold and engine) for cracks. If they are all fine, I'd swap the carburetor and see if that solves the problem. (It's hard for me without having the unit in front of me, so I hope this helps!)
mine does this when the engine is hot. I dont have problems starting it again, and if i hold the throttle a little this doesnt happens. What could it be?
@@NewScooters4Less I tried, but im do not sure if it works because i dont ride it till the point where engine is sufficiently hot yet. I have a vespa lx 125
I was having the problem of riding for 3-4 miles and then the moment i stop accelerating my scooter turns off. So i did what u recommended here and its working now, but could it be that now i have way too high idle ? My scooter sometimes starts moving with no acceleration and my fuel consumption went up like crazy? Could lowering help or you would recommend something else ?
Yes. Turning up the idle delivers more fuel to the engine to keep it running, so if it is turned up too much it will burn more fuel and it will start moving with no accelerator being turned. I would recommend turning it down. Sometimes you have to find that sweet spot between it being too low and dying out and being too high.
Hey man, I just bought a 2016 piaggio fly and it’s fuel injected, it has a starting problem where if you start ot and leave it it is fine, if u start it and turn it of straight away it will not start and u have to leave it for about 40 minutes to try start it again or else it will just run the battery out by trying to start it too much, I have checked the spark plug, checked if fuel was going through, charged the battery and the other day I pulled up at a red light and it cut out on me I tried to start it and wouldn’t start, tried this morning it started first time... I’m so confused In what it is. Sometimes if u leave it running a little u will hear a ticking noise in the variator case, may u have any ideas what the solution will be to fix the starting problem,thank you!

If your scooter starts and revs up but the rear wheel doesn't move, then you have a broken drive belt. You will need to take the transmission casing off and replace the drive belt. Thanks!
Did this before the next day it wouldn't start and am still having issues when i jump the battery it starts like that then i can adjust throttle again but without jump box even when the battery is charged it still doesn't start over just clicks... Anyone have tips?
Hey! We do not, but is it shaking uncontrollably or just a little bit. Usually this is due to a bent steering column. Did you run into a curb somewhere? Does it turn side to side ok or is it sticky or tough to turn the steering column?
Tried this today and it runs. But when it starts it makes a sputtering sound or it will stall and not turn on. It will after I do it again but I just don't like the first try
Maye your scooter is struggling to get fuel? Or has weak spark? There could be a good handful of things that are creating a sputtering sound unfortunately :/
hi i have problem with my yamaha vino 125 2006 has spark has gas exhaust is good valve is good crank but wont start i change the carburator cdi /coil / valve ajust compression check 140 psi still wont start what can be the problem [note i have 2 yamaha vino 1 running 1 not running ] thanks
john woo honestly man, I’m not going to be a lot of help here. Sounds like you have all of the requirements. When you say it ‘has gas’ does that mean that it just has gas in the tank or you know for a fact that gas is getting to the carburetor? How old is the fuel? If you have spark and compression, I’d replace the fuel / fuel system: new fuel, 93 octane minimum, replace fuel lines, fuel filter, and reclean the carb. Hope that helps.
Help! I adjusted my idle already and it wont idle anymore since like the 4th day i had it its been bogging out and now its getting worse and will barly start only 467 miles on it im foing to try and clean the carb on it to see if it helps any but idk it might be running too lean
My scooter does not have idle i give it gas it runs let off gas it dies. I've adjusted idle, don't work. Could it be something with accelerator handle or throttle cable?
Could be. May need to adjust the throttle cable where it attaches at each end to make sure it is not too loose. Probably needs to be tightened up. And if your scooter is carbureted, it has an idle adjustment.
@@NewScooters4Less I have a SYM JET 125 and I’ve learned that it’s not a carb and it’s fuel injected ??? How can I turn my. Idle down / revs on this bike please ahah

Hi new scooters for less I have a piaggio liberty 125 2007 UK model got it 6 months ago every thing was fine on it then tonight I was riding it and it started to jurk on me at about 30 mph then cut out all the lights and stuff was still on and the battery is new I started it again and it started so carried on my way home and it did it again another 2 times any ideas of what it could be intercepted did the thing in your video but still doing it it's weird cause it starts up again no problem just when I am riding for a bit it starts please help would be great
It's too difficult to say. I would get it into a shop and have it checked out. It sounds like it could be electrical. It could be a lose ground, could be a bad coil / spark plug cap, etc. Because there are many possibilities, it's really difficult for me to diagnose without having it here in front of me. Do you have a shop you can get it to?
@@NewScooters4Less yes I do it has new oil in it new oil filter new air filter new sparkplug and a new battery when I got the scooter the battery was bad so replaced it has new front and back brakes new speedo cable new back brake cable the work was dun by me 2 months ago and it's been running really good till that happened yesterday I looked at your video about the idle screw did it yesterday had it out the day and it did not jurk or cut out but my engine oil light is flashing on when I come to a stop now that only started when I adjusted the idle screw today do u know y this is happening? ?
@@johngourlay5804 No. Completely unrelated, unless you adjusted the wrong screw. Your scooter may have an oil adjustment to adjust the amount of 2-stroke oil it is getting to control the ratio being injected. I'm not too familiar with a 2007 UK Piaggio Liberty. That would be my assumption based on the information you gave me. There could be several possible issues I'm afraid. :/
@@NewScooters4Less thanks bud it's not a 2 stroke it's a 4t 125cc bud and it was defo the proper screw way the spring on it i checked online to see where it was located took it for a drive for a hour and a half the day it never cut out or died on me there is no oil leeks cause I would notice it on my floor I just got new oil and filter so will do that to see if that helps and it mite not mean anything but I am in Scotland UK and it's very cold at the moment could it be that ?
@@johngourlay5804 Possibly. I feel like scooters are always more difficult in colder climates and higher elevations as well. Maybe I could come over for a visit? It's been a while since I've been to Scotland! :)
Scooters have an automatic choke that helps with this in those first few minutes, but I find them to be ineffective sometimes based on certain climates (how cold it is outside, etc.) I always think it's a good idea to let the scooter warm up for a couple minutes, but we live in Florida and when we go outside in summer, the scooter is already warmed up, lol. If your idle is too low and your scooter is dying every time you stop, turn it up a tad. Just don't turn it up too high.
My Chinese scooter has had this problem before, was fixed by a mechanic but now doing it again. The mechanic said something about an air filter getting wet or blocked and you can tell when the engine sounds very quiet there’s an issue. It has had trouble starting too but strangely enough starts easier with the front brake pressed rather than the rear brake ?!
The brake thing is probably just a brake switch issue. If your carburetor is gunked up, fuel may be getting down into the air filter and soaking into the air filter which most certainly keep your scooter from starting. You would need to remove the air filters, clean it, let it dry out, clean the carb and put back together again.
New Scooters 4 Less thanks. It’s due a service soon anyway so I’ll let them take a look, he did attach an extension to the mudflap previously in order to stop so much water/gunk getting into the air filter so it could be connected to that. However temperamental it is to start, once I’ve ridden the 15miles to work if I turn off the engine then restart, it fires up just fine even with back brake depressed. Anyway I guess I’m doing ok from a budget Chinese scooter having done 15.000km in 18 months having never ridden before at the age of 43 :) ! Oh and not fallen off - yet !
New Scooters 4 Less yes it is a four-stroke. I’m not sure if he adjusted the valves last time but if he did it’s 6months ago. I’ll take it in for another service soon but at least it’s going for now and once it’s been running a while it seems fine. :)
Worked like a charm ty.... I have to say owning a moped has taught me allot about mechanics and i cant wait to get my hands on something more deep! 😃
You're welcome! Scoot safely!
Same.. The two I have owned n currently own have had me be more in tune then MOST men
You guys are so kind to have made a video based off of someone's question on another video.. and I learned something new! So cool bc my son's scooter has a very low idle. THANK YOU!!
So glad we could help! Thanks for the note! 💚
Singlehandedly solved my scooter's starting problem, and about 12 other people's throttle problems. THANK YOU!
Love to hear it!
All very new to the bike world and after spending over £500 and still having the same problems this video has solved the problem .. no idea why the garage didn't pick this up but I've one happy son now .. thank you 👍
Glad we could help!
You guys are great I just buy a new scooter 2 week ago then start turn off but I learned today from you and am not going see mechanic but I will do it myself. Thanks for the video
Glad we were able to help!
If this works you are literally saving me. I have been to four mechanics already for this problem and they all say that there isn't anything wrong and that the problem is with how I'm stopping.... I will try this tonight!! Thank you!
If it's not this, then it may be a vacuum leak somewhere. May want to have the mechanics check for that.
when the wheel spins on idle tho its not enough to move you but it does mean that the clutch is in contact with the bell and that means wear. what i do is I run the engine cold, and when the enricher stops, it drops in a very low rpm, that's when i adjust it low enough that it doesn't stall after the enricher turns off.
Thanks for the tip!
From what I've understood is that, when the rear wheel starts moving, it's not idling thru the pilot jet, the main jet kicks in.
Yes sir. It's a 150. I couldn't reach the screw,nor could I see if it was a torx, Phillips, or hex. So I took it to the local motorcycle shop in visalia ca. The guy said it was a 2.5mm hex. So he gave it a turn or two. Brought up the idle and away I went. (He didn't even charge me)
I rode around town like i had been doing before. And after over an hour or so of riding in city traffic, making u turns and stopping at intersections.. The bike give me no more problems. 🤙🏾
Awesome! Well, I'm glad to hear that! Safe riding!
Hey man just bumped into this I appreciate it so much I had to keep my hand on the throttle for a good minute getting home and doing this helped my scooter stay on well appreciated boss💪🏽🤞🏽
Awesome. Glad it helped!
Thank you this helped. The screw seems lose though like when i turn it to the right, it wants to slowly move back to where it was
It definitely shouldn't do that. I would need to see what is going on to have a full understanding... Sorry I can't be more help.
This is the exact problem I am looking to solve. THANK YOU!
Hope it helps!

Ive got a 250cc scooter the other day I was riding it and it felt like it was running out of gas but it picked up started running but it doesn't have the acceleration like it did before that ordeal
Sorry to hear that. Probably a fuel or air issue. I'd get it to a tech when you can.
Just want to say thank you because this video taught me how to adjust the idle of my Typhoon 125.
Love it. Our pleasure. Scoot safely!

Excellent! :)
Mine has this problem won’t idle and drives nice when I’m on it but soon as I let off the revs bogs out .. my bike does not have an idle screw so what then
Does it have a carburetor? Sounds like it may be fuel injected? I'd try to get it into a shop nearby to see what's going on. Sorry we can't be more help with this one!
Hay
Nice video
My problem is my ped wants to keep pushing when I stop . Would turning the idle screw down help me ?
Yes, if your idle is indeed too high, this would help. However, other issues like a broken clutch, clutch spring, etc. could also cause the rear wheel to "stay engaged" and keep moving as well. But start by adjusting the idle and see if that helps, especially if your idle speed is revving very high.
What can cause this problem though as my scooter has been running perfectly up till this started.
Thanks.
You could have a vacuum leak. Check vacuum hoses, etc. to make sure there are no cracks, etc.
hi, i didnt use my scooter this winter, and now, when its on the stand its starts but when i leave it down it will just cut out, i kept it running on the stand a few minutes to warm up but then it was doing the same, do you know what it could be??
Is a vacuum line or fuel line getting pinched by something when it comes off the center stand? I would check your lines to make sure they aren't caught up in a shock or something.
@@NewScooters4Less even if the scooter is not running and is not on stand it dosent start, i was thinking is something to do with the wheal being in the ground and not being able to spin..
@@sarahmulqueen9014 I'm not sure I understand. If it's starting and the wheel won't spin and feels stuck, you could have a broken clutch spring or another transmission problem.
@@NewScooters4Less sorry about that english is my second language, the wheal is spinning when is on the stand, but when i leave it down the engine just stops, and its a 125 cc twist and go there's no clutch, its ok nevermind i think i need a mechanic to check it properly, thank you
@@sarahmulqueen9014 Not a problem. If the wheel is spinning when it is on the stand, the idle may be turned up a tad bit high. There is a clutch, but it's a CVT transmission (meaning it's automatic, aka - twist and go). I would definitely get it into a shop when you can! Good luck!
what about the opposite.
so mine works well cold, picks up very quickly. but after 2 mins then the bike bogs , i then have to fether the throttle up to it gets to a higher or around 20mph speed then works fine.
please get back to me if you get yhe chance.
many thanks, rich
Vacuum leak possibly. Check for cracks in the vacuum line, intake manifold, intake manifold gaskets/spacers.
Straight forward and to the point thank you!!!!
Glad you found it helpful!
I have the exact same problem with my scooter, except mine has fuel injection, not a carburetor. What should I do with it? And it's not just when it's cold, it happens all the time for me. I check the engine, and don't think that there is an idle adj screw like the one in this video.
Unfortunately, I think you might need to get this one into a shop for a proper diagnosis :(
My issue: Where you have it on the center stand it idles fine, but the back wheel is moving. When I hit the rear brake, then it dies out. It's like the power from the motor never disengages from the back wheel. Thoughts?
Is your concern that the back wheel is moving when it is on the center stand? (As long as the scooter doesn't feel like it is pushing you when it is on the ground,) it's ok for the back wheel to move a little bit when on the center stand because when it is on the ground, it won't. Does that make sense? (Think about it like a car... When you take your foot off the brake in a car and it is in Drive, it wants to creep forward. Your foot on the brake is keeping it from moving forward. It's similar with a scooter... when your scooter is off the center stand and on the ground, the brake and your body weight keep the scooter from moving forward (unless of course the idle is too too high and the scooter feels like it is pushing your forward when idling)). Hope that helps!
Oh it’s definitely pushing me. It jerks the whole scooter with each stroke of the motor until it dies. I’ve adjusted the carb with the same symptoms. That’s why I wonder if it’s the transmission assembly
@@93paxon I'm almost willing to bet it is 100%! Sounds like the clutch may still be engaged when you are at a stop. Probably a popped spring on the clutch assembly! Definitely check that out!
Thks four your video I have a Peugeot V-Clic 50cc 4T from 2012 is same carburetor when I start up the idle is keep up and down up again and down is any reason ??? Thank you very much Jersey uk ❤
Hard to say. Check your vacuum lines and air filter to ensure there are no cracks in the lines, etc.
I have the same scooter too!
So.i did this and found it still wasn't staying on I went to the throttle cable on the carb and now it revs wayyyyy to high and if I even move the screw it dies down if I adjust it ... What am I doing wrong or what do I need to adjust instead the cable back more slack or tight ? And loosen the bold more ? I'm at a loss going 30 mph with 100 cc
I'm sorry. I would need to look at this one in person. Do you have a shop near by?
You saved my life just got a 2020 beast grom bike just yesterday and it started dying out on me ...mind you I. Don't know anything about bikes so I started to freak out 😂😂😂 but I came across your video and Wallaa just like that it stayed on
Happy to hear it!
I jus bought a new scooter yesterday. Engine bogs down and cuts out all the time, especially when i indicate or have lights on. Freakin annoying. Jus soent a grand on a faulty bike on gumtree, feels bad man.
WIth it being that new, I'd take it back where you bought it. If it bogs down when you use indicators, etc. then it's probably an electrical problem. I would start diagnosing by checking all your ground wires first to make sure none of them are broken.
HELLO PLZ HELP ! when i start mine , it doesnt a actually keep that rev ... in about 4 seconds it allways die out when stoped ... SO can it be screwing it up a little when its OFF then see if it fixed ??? and is it propubly coz the battery thats dying? or a some dirty in the carb???? thnx a lot
Could be a vacuum leak. Look for cracks in the vacuum hose or the intake manifold. I'd start there.
Fairly new apriliia storm scooter. Engines dies when throttle is pulled. But doesnot have any problem once it gets warmed up. Will this solve the issue. It happens everyday when trying to start the scooter.
Check the fuel-air mixture. Some scooters have a screw to adjust. You may be able to adjust the needle in the carb or you may be able to adjust how much air is being sucked into the air filter. Sounds like an adjustment there will help.
Question even after this fix mine won’t stay on when idling after a bit what else could I try?
Check for a vacuum leak. There could be a crack in a vacuum line, intake manifold, etc. I'd start there.
@@NewScooters4Less okay thank you
@@midnighte7393 my pleasure
Hi thank you for your video I have a Piaggio Zip 50 2T when I drive and give a full acceleration is luck like is cutting down you don’t now way please thank you
I'm not sure what you are asking me here. I'm sorry. Can you try to rephrase?
So we changed the idle but our issue is it’ll start on the stand but struggles on the ground. (Resistance on the wheel) we’re thinking maybe something with the clutch? It dies anytime there’s resistance on the rear wheel ie body weight, brakes
Yes. You could have a broken spring on the clutch or another similar issue. I would definitely pull the transmission casing off and look at that clutch and transmission.
@@NewScooters4Less After I sent this I pulled the cover off and found the issues. The ceramic pads for the clutch were all broken and pieces were everywhere. Ordered a new clutch and transmission assembly that I will be putting on later today!
@@Consi2536 Excellent! I am glad you discovered the issue!
Hey, I have the same problem with Yamaha Neos 2009 4 stroke engine, how to solve this?
Does it have a carburetor? Can you make this adjustment made in the video? Also check for vacuum leaks (cracks in the vacuum lines, crack in the intake manifold, etc.)
So what having a similar problem but not when stopping so basically everything all fine but when I turn my steering all the way or even half way to the left it cuts the moped off what would be making it doe that as I use my moped to go to my little brother grave from time to time only way I I’ve to get there and to check on him
Check your ignition wiring. When you turn the steering, it is probably pulling on the wiring and causing the ignition and/or kill switch to function which is cutting it off. I'd bet it is something in that wiring up front by the steering. Also check the wiring for any cuts, tears, etc. in case something is rubbing the frame and shorting out (but my guess is that you would be popping fuses if that was happening).
@ thank u so much new to this stuff are do all the checks u just told me to do in abit Is only a old Yamaha vitty so shouldn’t be that hard if is what your saying it is thank u again for the help
@@ActiveMzzzz Best of luck with it!
For me? It seem to be a different problem.. As if the Starter clutch or drive clutch is sticking when I hit the brake. My scoot stops as soon as the wheel stops?
Have you opened the transmission casing and looked inside? Maybe a broken spring in there on the clutch or something. Should be able to pop off the case and take a look around.
Hi please I have tried adjusting like you sai but is not working for my kymco scooter is either I higher it if I try lowering anytime my hands let go off the gas then it automatically go off what could be the solution
You probably have a different issue. My guess would be a vacuum leak somewhere. Check your vacuum lines, intake manifold, and make sure that there are no cracks where air could be escaping. Thanks!
When I turned this screw on mine, I know I used to be able to make it so my idle rpm was high enough to get my wheel turning, but lately with the screw turned up completely, my idle is only about 1200 rpm, which is nearly enough to keep the scooter running, but sometimes not quite.
hmmmmmm... you have the idle screw screwed all the way in?
Hey I have a 4stroke motofino 150cc. It starts and idles fine but when go to accelerate it bogs down and shuts off. Any suggestions?
Fuel air mixture? Probably getting too much of one or the other. It probably has a fuel / air mixture screw you can adjust.
I have an opposite case. The idle is slightly high and my scooter is pushing forward in idle. So I tried adjusting that screw by unscrewing it as far as it could. But that's not bringing down the rev. What's the problem?
Is your throttle cable too short? Did you recently replace that? You should be able to adjust the cable some too at the throttle handle and on the carb. It could be pulling to much on the carb (giving it too much gas)
I have a brand new scooter and it dies as well at an idle or coming to a stop. We have adjusted the throtal and that doesn't help it. We have had nothing but issues from the get go. The automatic electric choke was burning out, magneto was not gapped properly, the company we purchased it from sent us a new carborator and everything. Do you have any idea what we should check before my boyfriend throws it in a ditch somewhere?
What kind of scooter is it?
@@NewScooters4Less it's a VIP future champion. We finally figured it out though the valves needed to be adjusted. Now it works great. Funny but he actually got pulled over for going 45 on it when top speed with out a motorcycle license is 30😂
@@jessicayoung6822 Yep! That can definitely create a problem! So glad to hear you got it figured out! (Slow down! Lol!)
Question does turning the idle screw up mess with the performance of it when u ride the bike or nah
It can to a degree. For example, if it is too high you are burning more fuel when just sitting at idle.
Hi, I have a concern in my scooter. Every time I slow down to turn or ride across a hump on a road, my sccoter will suddenly have a slight burst in speed. Is there any fix to this? I tried adjusting the idle speed but it's still doing the same speed bursting
Hmmmm... maybe a vacuum / air problem. Check your vacuum lines to make sure they aren't getting pinched by a shock or something when you turn. Also make sure none of the lines are interfering with your throttle cable on your carburetor.
Please help, I'm not getting any gas to stay into the carburetor, in order to fuel the motor . have tried another carb as well. Does the same thing..., please reply..,
If you aren't getting fuel to the carburetor, then you may have an issue in the vacuum system or fuel pump. Make sure there are no cracks in your vacuum lines and then replace the fuel petcock that attaches the fuel tank to the fuel lines and filter. It could be faulty.
So today I’m going to buy myself a gilera runner 180 vx witch is the 4stroke version the bike starts up fine and rides nice but once I come to a stop it dies out but will start back up and go again also the bike seems to back fire and crackle and pop I was thinking if not the idle maybe I should try clean or change spark plug and old oil?
Probably fuel and air mixture is off. I don't know anything about that bike, but I would look at spark plug, carb, air filter, vacuum lines and make sure everything is good there.
What do I do when it’s maxed out the screw it turned all the way and the idle is still rough and it stalls out
You have a different problem. Could be a vacuum leak / issue. Could be something internal with the carb. Could be an airflow problem. Could possibly be electrical too. Sorry! May need to have someone look at it :(
What if I do this and it doesn’t work, when I higher the acceleration the wheels move to much and when I lower it just sounds like it’s going to die again, there’s no in between with mine, maybe battery ?
Check for vacuum leaks. Could be a crack in your vacuum line, could be a crack in the intake manifold, etc. Thanks!
I have italika motor D125 in any weather when i turn on the scooter the battery makes a sound and wont turn on,so i need to kick start the scooter
what seems to be the problem??
Does the battery work well in the warm weather? Could be cold-cranking amps in the cold. Could be tight valves and need an adjustment. Could be a variety of things, but a valve adjustment is probably what I would look at first.
Check the air filter also to make sure it's getting enough airflow? Then re-adjust the idle?
Sometimes you can have an air leak, vacuum leak, etc. Definitely make sure your airflow is good too. Then, yes. If all is good. Tune the idle.

hi my tgb cuts out as soon as i let go of a brake lever doesnt matter which one,it starts up and runs fine untill i let go of brake ,ive disconnected each brake switch in turn but still does it,any ideas as im running out of things to try.
Does the scooter feel "engaged" when you let go of the brake? You could have a broken clutch spring or something inside of your transmission.
it does run you can ride it up the road as long as you have the brake pulled in enough to not close the switch,i was wondering if it could be the rear light as ive got it fitted to the rear box and not the frame,so maybe its because the rear light isnt earthed to the frame,what do you think could that cause it to die when brake released,not earthing properly

No quick fix. Sounds like there is water in the system that is causing issues. Is the water in the oil or the gas? Sounds like it is in the gas if it is coming out of the carburetor.

I’ve tried this on my 125cc moped and it didn’t work as good so I cleaned the carb to see if that worked still didn’t work it’s a 2022 plate so I’m not sure it also loose power
Could be something else causing your issue. Do you have a shop you can take it to?
My rear tire always spins even with the idle adjustment to low any idea how to fix this?
Is it spinning fast? If it's spinning really slow, it's not a big deal.
Hello sir what about when I reduce speed and the moped shuts off ? Is that normal ? I just bought it new and started riding it today thank you in advance
Did you try doing what's shown in this video? Sounds like the idle is really low.
It worked thank you so much 🙏🏻🙏🏻🙏🏻
Great and helpful video
@@selfimprovement212 Awesome. Love to hear it!
@@selfimprovement212 Awesome. Thanks for watching!
How about if you don't want to adjust it to above 4000rpm idle just to keep running 🤔. How do you fix to keep 2000rpm when it wants to die out?
Maybe set at 3000 rpm? I think it's just finding a nice medium.
@@NewScooters4Less Factory recommended idle for Ruckus is 2,000 rpm +/- 100. Turns out I was losing compression because the service tech didn't seat spark plug all the way 😒
@@fisher5413 Ahhhh.. Gotcha. Glad you got it sorted out!
Where can I find this screw in Lexmoto titan 125cc?
I'm not familiar with that scooter. Is it fuel injected? If so, it wouldn't have this.
I had that problem, to solve it I set the air/fuel mixture screw 1-1/2 turns out and then the idel at 1900rpm when cold, after warmup rpm is at 1900~2300 problem solved.
Nice.
Must be nice that this solved everyone else's problem with it. Mine however still stalled anytime I hit the back break whether I tightened or loosened it so what's the next reason it could be doing this.
Check your vacuum lines that run from the intake manifold to the fuel petcock and make sure there isn't a crack in them. Also make sure there isn't a crack in the intake manifold spacer that goes between the intake manifold and the head of the motor. Could be a crack somewhere.
Thank you I got that problem when the engine is cold it turn off i need to do that tomorrow morning ill do that
Sounds good!
Do you know if I can do this on a 2008 Sym Symply? Has a low idle but I'll try this tomorrow and see if it had the screw
If it's a 50cc, it should have an idle adjustment. If it's 2-stroke, it may look different, but it should still have one.
thank very much its will help to check my cygnus it is died whem i stop
Awesome. Glad we could help.
Mine idles high at a cold start and then after awhile slowly dies down until it turns off this is without touching the throttle but if I touch the throttle I can keep it does a misfire little bit and I'm thinking that's a spark plug issue but I'm not sure what's your guy's is your adVice
Depending on what kind of scooter it is, it probably has an electric choke attached to the carburetor and that is why it slows down after it has been running. Is it only doing the little 'misfire' after you first start it? May want to give the scoot a couple minutes to warm up. If it is misfiring while all the time, then you could have a spark plug issue, but it could be a few different things. I'm not sure where you live, but maybe just let the scooter warm up for a few minutes before going and see if that helps.
i have an efi lexmoto venom and it keep cutting out, i have changed spark, just had service new air filter, any ideas where to go from there
Are you sure it is getting fuel properly?
@@NewScooters4Less I think so, if I keep the throttle open it won't stall, it doesn't seem to be under power, the bike moves as fast as a want it to. I have put fuel cleaner tho it to make sure nothing is blocked to much or dirty, about to fill it back up.
@@MrStitty26 Is it bogging and dying or is it just shutting off while driving? It could be losing spark while driving. May not be the spark plug, but could be coil, cdi, stator, etc.
@@NewScooters4Less it will only stall on idle so at light or when a have stopped, when i keep the throttle open it run great, one thing that dose happen is when i take of the accelerator it sounds like a bag off popcorn in the micro wave. also had a look today and noticed that there wasn't a cdi unit under the seat but the connector is there for it, but id imagine it wouldn't run at all without one. dose have an ecu under the tank as well.
@@MrStitty26 This isn't the problem is it? Check this video: th-cam.com/video/v3G4tx3zcCY/w-d-xo.html
yes BJT MY SCOOTER IS AN ELECTRONIC FUEL INJECTED ( EFI ) BUT I AM HAVING THIS SAME PROBLEM A 2018 SINNIS HERO 125cc
Sorry to hear that. I am not familiar with that scooter, so see if you can find a repair center near by. Best of luck with it!
Hey, I have a problem with my scooter it dies when I'm riding especially at high speed and when it's idle to warmup
Like while going full throttle and driving, it will cut out and die? Probably electrical. Check/replace your coil and CDI... Sounds like you could be losing spark when the unit gets hot.
thank you man! my scoot scoot just started knocking off at stops today. So i tried doing this and BAM! good as new! thanks again.
Awesome! Glad it helped!
so, this happened after i went over a huge pothole. engine has not been running well since. the engine dies every time i stop while warmed up, and choke is extremely high when cold. throttle is also very sluggish when i try to give it gas from a standstill while warmed up. i suspect something like a hose came loose, but have not been able to find the problem yet
I'd bet the same thing. Check to ensure that your intake manifold (between the engine and the carburetor) is tight and not loose or cracked. You could have a vacuum leak somewhere. Also check to make sure that the air box that attaches to the other side of the carburetor didn't pop off. Make sure it is nice and snug on the carburetor. Make sense?
@@NewScooters4Less i checked the vacuum lines and intake manifold. No problems. I also discovered another thing. The scooter works completely fine, every time i take it out of my basement, as if nothing is wrong.
Although if I leave it outside in the winter weather and start it cold, that's when the problem occurs. Same problem, it idles high when it's cold, and sputters/bogs more and more as it warms up. Dies completely after driving for a minute, (especially when releasing the throttle) and won't start again until cold.
There is spark, and the spark plug is brand new.
After it died on me i removed the spark plug and inspected it. It was a little black, not too much, which usually is a sign of a rich mixture, but no other signs of it, such as visible exhaust smoke and rotten egg smell. (And as i mentioned runs perfectly when stored inside)
I checked the valve clearances and it was 0.05mm intake and 0.08mm on the exhaust.
Something seems to be malfunctioning when it has been sitting in the cold weather.
@@thatshot-ey8kh Scooters HATE the cold weather. Especially when it is carbureted and not fuel injected. Our dealership is in Florida and it is even a struggle here. They are going to be difficult to start in cold weather. Once you get it started, you want it to warm up for at least 5 - 10 minutes before riding. Once the motor is nice and warm, it will usually be fine. The carburetors have an automatic choke to help with this problem (which is why it starts off idling high). When the motor warms up, the automatic choke cuts off. Just sounds like your scooter (like most) is finicky with the cold weather.
@@NewScooters4Less oh right, forgot to mention that i do let it warm up, but when i do, it idles increasingly faster and faster, close to spinning the back wheel. After a minute or two, the idle plummets and the engine dies. It starts up again but not without throttle. The throttle is very hesitant and unresponsive, no matter how much i give it. It can drive for about a minute, until the bogging gets to the point where the engine just stalls regardless if i'm stationary or driving, or giving it throttle or not.
I am certain that there is something wrong with it, because last year it would stay outside for eight hours while i'm at school in -5 degrees celsius compared to the 8 degrees now, but started and drove flawlessly back then.
-it gets spark, fuel and air.
-it has good compression
-the problem only occurs after sitting outside for some time in the cold weather.
-drives flawlessly if stored inside
-it has 4634 km on it
Maybe it's something electrical? Like the enricher?
@@thatshot-ey8kh Have you adjusted the valves on this machine since you've had it? You may want to try that. Besides that, I'm not sure how much help I can be. What I can say is that my experience scooters is that they are super finicky in extremely cold weather. Here in Gainesville, if it gets below 40 degrees F, the number of calls we receive related to scooters not starting or working properly goes way up. Best wishes with it my friend.
My scooter doesn’t want to start well when the engine is cold. Is there anyway to fix this? The scooter will start but it doesn’t feel like it’s fully started. I try to give it gas and it dies. I have to slowly give it gas for it to actually start up, if I give it to much gas it dies. How can I fix this?
Where are you located? What kind of scooter is it? How many miles are on it? I need more info so I can try to help! Thanks!
I have a similar issue except that the idle on my scooter increases after lowering it . I’ll lower the idle so that the scooter doesn’t pull forward but once I give it throttle the idle revs higher and stays there along with the back wheel constantly turning. I have to constantly adjust the idle lower and it’s super annoying. Any suggestions as to what to do or how to fix it? What could be the cause? Thanks!
Also after I stop giving it throttle it stays at an higher idle than before.
@@jarodhuber2687 The throttle isn't getting stuck open some how, right? Also, check the vacuum lines, intake manifold, and intake manifold spacer (between the manifold and engine) for cracks. If they are all fine, I'd swap the carburetor and see if that solves the problem. (It's hard for me without having the unit in front of me, so I hope this helps!)
mine does this when the engine is hot. I dont have problems starting it again, and if i hold the throttle a little this doesnt happens. What could it be?

Can you please help me I have a 150cc gy6 Jmstar motor scooter it a crank right up run for a minute and then cut off back off
How many miles are on it? My first intuition is timing of the engine. I'd check the timing and check the valves. Pretty common with 150 GY6.
I was having the problem of riding for 3-4 miles and then the moment i stop accelerating my scooter turns off. So i did what u recommended here and its working now, but could it be that now i have way too high idle ? My scooter sometimes starts moving with no acceleration and my fuel consumption went up like crazy? Could lowering help or you would recommend something else ?
Yes. Turning up the idle delivers more fuel to the engine to keep it running, so if it is turned up too much it will burn more fuel and it will start moving with no accelerator being turned. I would recommend turning it down. Sometimes you have to find that sweet spot between it being too low and dying out and being too high.
Hey man, I just bought a 2016 piaggio fly and it’s fuel injected, it has a starting problem where if you start ot and leave it it is fine, if u start it and turn it of straight away it will not start and u have to leave it for about 40 minutes to try start it again or else it will just run the battery out by trying to start it too much, I have checked the spark plug, checked if fuel was going through, charged the battery and the other day I pulled up at a red light and it cut out on me I tried to start it and wouldn’t start, tried this morning it started first time... I’m so confused In what it is. Sometimes if u leave it running a little u will hear a ticking noise in the variator case, may u have any ideas what the solution will be to fix the starting problem,thank you!
How many miles are on it? Has it had a valve adjustment? The ticking could be the valves tapping.
@@NewScooters4Less 16k miles mate
@@Bimahs I'd have a technician check the valves.
@@NewScooters4Less Would that sort the starting issue?

CT Spoder you may not need a new carb necessarily. Do you have vacuum leaks? Is the fuel bad? You might need to clean the carb.

Hello I have a moped 150 mL and I was on it and I heard something pop in and when I hit the throttle it doesn’t run but is still turned on all the lights any idea what might be going on I’m trying to fix it myself with no experience so any idea that will be a great help thank you
If your scooter starts and revs up but the rear wheel doesn't move, then you have a broken drive belt. You will need to take the transmission casing off and replace the drive belt. Thanks!
Did this before the next day it wouldn't start and am still having issues when i jump the battery it starts like that then i can adjust throttle again but without jump box even when the battery is charged it still doesn't start over just clicks... Anyone have tips?
Is your starter solenoid bad? Also... check for loose grounds. Sounds like a ground may not be attached or may be loose.
Thanks a lot!! It was very helpful, my Vespa 125, kept on dying at a stop sign!!!!
Glad we could help Mick!
Do you have a video to help with a 50cc moped front wheel/ steering shaking when reaching 30-35 mph?
Hey! We do not, but is it shaking uncontrollably or just a little bit. Usually this is due to a bent steering column. Did you run into a curb somewhere? Does it turn side to side ok or is it sticky or tough to turn the steering column?
Idk, but it seems my idle is pretty normal. But my real wheel rotate fast. Any advise sir?
Clutch spring could be broken causing it to stay engaged? That's the only thing I could think of if you don't have carb or vacuum-related issues.
Tried this today and it runs. But when it starts it makes a sputtering sound or it will stall and not turn on. It will after I do it again but I just don't like the first try
Maye your scooter is struggling to get fuel? Or has weak spark? There could be a good handful of things that are creating a sputtering sound unfortunately :/
hi i have problem with my yamaha vino 125 2006 has spark has gas exhaust is good valve is good crank but wont start i change the carburator cdi /coil / valve ajust compression check 140 psi still wont start what can be the problem [note i have 2 yamaha vino 1 running 1 not running ] thanks
john woo honestly man, I’m not going to be a lot of help here. Sounds like you have all of the requirements. When you say it ‘has gas’ does that mean that it just has gas in the tank or you know for a fact that gas is getting to the carburetor? How old is the fuel? If you have spark and compression, I’d replace the fuel / fuel system: new fuel, 93 octane minimum, replace fuel lines, fuel filter, and reclean the carb. Hope that helps.
Help! I adjusted my idle already and it wont idle anymore since like the 4th day i had it its been bogging out and now its getting worse and will barly start only 467 miles on it im foing to try and clean the carb on it to see if it helps any but idk it might be running too lean
If it's bogging out, definitely check the carb and check the air filter. Sounds like a fuel / air issue. Are you putting the proper fuel in it?
My scooter does not have idle i give it gas it runs let off gas it dies. I've adjusted idle, don't work. Could it be something with accelerator handle or throttle cable?
Could be. May need to adjust the throttle cable where it attaches at each end to make sure it is not too loose. Probably needs to be tightened up. And if your scooter is carbureted, it has an idle adjustment.
Mine spins ALOT more than that.. is that a problem ?
The rear tire does? Does adjusting the idle down slow it down?

@@johngourlay5804 No. Completely unrelated, unless you adjusted the wrong screw. Your scooter may have an oil adjustment to adjust the amount of 2-stroke oil it is getting to control the ratio being injected. I'm not too familiar with a 2007 UK Piaggio Liberty. That would be my assumption based on the information you gave me. There could be several possible issues I'm afraid. :/

@@johngourlay5804 Possibly. I feel like scooters are always more difficult in colder climates and higher elevations as well. Maybe I could come over for a visit? It's been a while since I've been to Scotland! :)
It happens twice to me, I usually don't wram up my sccoter, do I have to warm it up for 10 minutes?
Scooters have an automatic choke that helps with this in those first few minutes, but I find them to be ineffective sometimes based on certain climates (how cold it is outside, etc.) I always think it's a good idea to let the scooter warm up for a couple minutes, but we live in Florida and when we go outside in summer, the scooter is already warmed up, lol. If your idle is too low and your scooter is dying every time you stop, turn it up a tad. Just don't turn it up too high.
My Chinese scooter has had this problem before, was fixed by a mechanic but now doing it again. The mechanic said something about an air filter getting wet or blocked and you can tell when the engine sounds very quiet there’s an issue. It has had trouble starting too but strangely enough starts easier with the front brake pressed rather than the rear brake ?!
The brake thing is probably just a brake switch issue. If your carburetor is gunked up, fuel may be getting down into the air filter and soaking into the air filter which most certainly keep your scooter from starting. You would need to remove the air filters, clean it, let it dry out, clean the carb and put back together again.
New Scooters 4 Less thanks. It’s due a service soon anyway so I’ll let them take a look, he did attach an extension to the mudflap previously in order to stop so much water/gunk getting into the air filter so it could be connected to that. However temperamental it is to start, once I’ve ridden the 15miles to work if I turn off the engine then restart, it fires up just fine even with back brake depressed.
Anyway I guess I’m doing ok from a budget Chinese scooter having done 15.000km in 18 months having never ridden before at the age of 43 :) ! Oh and not fallen off - yet !
@@davidwil58 May also need a valve adjustment. Have you had that done recently? It is a 4-stroke scooter right?
New Scooters 4 Less yes it is a four-stroke. I’m not sure if he adjusted the valves last time but if he did it’s 6months ago. I’ll take it in for another service soon but at least it’s going for now and once it’s been running a while it seems fine. :)
