THE JOURNEY
Early in 2004, an opportunity presented itself that would forever change the direction of my life and the culture of an entire community. I would sit at a bus stop day after day trying to catch an RTS bus to campus and this bus would pass me by with the words FULL BUS displayed across the top ultimately leading to the creation of New Scooters 4 Less in March of 2004. 13 years later (now as sole owner), New Scooters 4 Less (NS4L) is one of the largest scooter dealerships in the United States and continues to break it's own records and the sales records for some of the top scooter distributors in the country. NS4L has provided jobs to tons of amazing people, reached millions of dollars in revenue, sold thousands of scooters, and has serviced thousands more. Read More... www.collinausti...

[@joash480]

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.

[@NewScooters4Less]

Thanks for the tip!

[@Tipi83]

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.

[@jesusmejia3910]

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. 🤙🏾

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.

[@NewScooters4Less]

Nice.

[@tfmobilewash840]

Usually when it does that its because you might need some valves adjustment.

[@Gerdaldfighterkid]

I like this guy as a person

[@NewScooters4Less]

Thank you!

[@BattleAngelFan99]

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.

[@NewScooters4Less]

hmmmmmm... you have the idle screw screwed all the way in?

[@robertsommers583]

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.

[@NewScooters4Less]

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.

[@Scarface_.666]

[@NewScooters4Less]

[@JayDillon-mm6yv]

Check the air filter also to make sure it's getting enough airflow? Then re-adjust the idle?

[@NewScooters4Less]

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.

[@scottgolightly1594]

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

[@NewScooters4Less]

Sorry to hear that. Probably a fuel or air issue. I'd get it to a tech when you can.

[@C.D.J.Burton]

My garage called that the throttle tension screw. They said that if you're tweaking t it to keep your scoot alive there's probably another issue! That's why once you've adjusted it, the engine doesn't die down as quickly as it did when you release the throttle. Maybe air leaks in the rubber manifold or the idle speed screw (on the side) isn't adjusted correctly.

[@NewScooters4Less]

The screw on the side (depending on the type of scooter) is usually a fuel / air mixture adjustment. With the idle screw (what I'm showing in the video), if you have to tighten it all the way down to keep it alive, there is definitely a problem. Like you suggested... a vacuum leak through the manifold, etc.

[@C.D.J.Burton]

+New Scooters 4 Less I believe the keihin carbs fitted to modern piaggio scooters have the air/fuel mix on the under side of the carb.

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.

[@NewScooters4Less]

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.

[@juliodiaz4493]

Thank you I got that problem when the engine is cold it turn off i need to do that tomorrow morning ill do that

[@NewScooters4Less]

Sounds good!

[@adamjordan4836]

My scooter is doing what you described. Problem is, my idle screw is already maxed out. I also adjusted the throttle for an idle. Now when it warms up the normal idle will rev higher and try to roll on a stop. It still starts like it's flooded and dies at stops until it warms up good. But onece the engine is hot it performs normal. I am guessing an adjustment at the air/fuel mixture. Or a leaky vacuum line. I will just put it in a shop and describe what's happening.

[@NewScooters4Less]

Yo Adam. I think you are on the right track. My first inclination was a vacuum leak somewhere. Also check the intake manifold. I've seen them cracked on the base sometimes.

[@jesusmejia3910]

My 2009 Vespa 150 LX ie is having the same issue. Im going to try this in the morning. Thank you.

Jesus Mejia let us know!

[@thefourwheelerdoctor7808]

That’s a temporary fix not a permanent solution to the issue.

[@NewScooters4Less]

If you're idle is just low, this will fix the problem. Been doing this for 17 years. Sure, there could be deeper issues... vacuum leaks, etc. but sometimes this is all you need.

[@elliotdownie7431]

I just put a 70cc cylinder on my aerox yq50 and the idle is now too low due to the larger volume cylinder not being filled with enough petrol.

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.

[@NewScooters4Less]

Unfortunately, I think you might need to get this one into a shop for a proper diagnosis :(

[@sleeplessgiant7407]

Great stuff ! Thank you ! My relatively new Piaggio scooter keeps dying out whenever I'm idle, I will try this when I get home ! I assume the screw simply gets a bit loose over time from all the bumps and shocks on the road.

[@NewScooters4Less]

No problem! It could come loose, but it's more likely that there are external factors leading to it... break-in of the vehicle / wear over time, warm / cool weather, etc.

[@JovanteeBlair]

@@NewScooters4Less Same thing with my brand new 2018 Bintelli Scorch that I got on November 19th, 2019. So I'm assuming it's either the warm/cold weather that keeps changing down here in St. Petersburg, FL, it breaking in, since it's coming near 500 miles, but currently at 450 miles, or my carb cleaned or replaced.

[@NewScooters4Less]

@@JovanteeBlair In this instance, probably breaking in. Your unit is so new that adjusting it and fine-tuning in the first 500 miles is pretty normal. Thanks!

[@frednetherlands887]

This is not a permanent fix for me. I got close to fixing this problem by tuning the jets to the right size, changing the needle position and adjusting the fuel/air screw. The idle screw will result in an idle to high when the engine is warm. These scooters are hard to tune idle wise.

[@NewScooters4Less]

Sorry to hear that. Hope you can fine tune it and get it locked in! Best of luck!

It can to a degree. For example, if it is too high you are burning more fuel when just sitting at idle.

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!

So the same thing happened with my moped, but when i give almost full throttle it dies out. What should i do?

[@NewScooters4Less]

Is it bogging down at full throttle or is it cutting out every time you give it throttle? It could be several things, but I would start by checking the air filter, making sure its clean and that there are no cracks or anything in the air box. Check for any air leaks (cracks) in the intake manifold (the part between the head and the carburetor). You could have some gummed up old gas in your carburetor / blocked jet, too. Has the scooter been sitting without use for a while?

[@roecigreview]

Is this problem related with any weather change?

[@NewScooters4Less]

You can see fluctuations in idle due to temperatures for sure. Some scooters are worse than others (cheap models). The warmer the motor, usually the higher it's going to idle.

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?

[@NewScooters4Less]

Maybe set at 3000 rpm? I think it's just finding a nice medium.

Is it spinning fast? If it's spinning really slow, it's not a big deal.

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

[@NewScooters4Less]

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.

[@murat.1907]

I did this but it still turned off. So the best way to fix this is to adjust your valves. That should fix it.

[@NewScooters4Less]

If you need a valve adjustment, then yes, adjust the valves. There are mileage intervals for this anyway and should be done periodically. Thanks.

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?

[@NewScooters4Less]

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.

Man my moped when I let go of the break my back wheel spins like crazy

[@NewScooters4Less]

Is your idle too high? Turn it counter clockwise to turn it down. If this isn't the issue, the throttle cable coule be getting pulled too tight on the carburetor or at the throttle handle. May need to adjust the actual cable.

[@Weekend_Gamer]

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

[@NewScooters4Less]

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.

[@everslimsmith8907]

Idk, but it seems my idle is pretty normal. But my real wheel rotate fast. Any advise sir?

[@NewScooters4Less]

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.

[@iancook5664]

Iv done this but mine still cuts out even if it’s been running all day

Sounds like you have a different issue. I'd get it into the nearest dealership for them to check it out.

[@owenbrown2322]

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 problem which I can't find an answer for. Is when I give it gas it'll rev up. But if I try to go it dies out

[@NewScooters4Less]

What do you mean? When it is on the center kickstand and you rev it up it will rev up, but the moment you take it off the kickstand and try to go it will die? To me this sounds like the seat or suspension is pinching a fuel line or vacuum line.

@@NewScooters4Less no when I start to give it gas it'll start to rev up then just die. But I think I found the problem. My gas tank has rust in it and it's clogging all my lines

Anytime you have an issue like that, it's usually fuel or vacuum related. If you have rust, that is DEFINITELY a problem. Purchase a new fuel tank for it. If you let me know what kind it is, I may have one in stock here.

Could be a vacuum leak. Look for cracks in the vacuum hose or the intake manifold. I'd start there.

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!

[@jenishmaharjan1997]

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.

[@NewScooters4Less]

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.

[@thatshot-ey8kh]

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

[@NewScooters4Less]

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?

[@thatshot-ey8kh]

@@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.

[@NewScooters4Less]

@@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.

[@thatshot-ey8kh]

@@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?

[@NewScooters4Less]

@@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.
