Something I don’t mention in the video, is that the carb is electronically controlled not only to limit bhp to a leisurely 3, but also for fuel economy and emissions. These things actually have a lambda sensor, and the ECU controls the carb mixture too.
what advice can you give about the ecu? can you remap the stock ecu and derestrict it or do you have to buy a whole new one
@@acegik7157 they’re supposed to be able to be remapped, but I’ve not found anyone who can do it yet.
@@StupidBlokeStupidVideos thanks for the answer, im gonna see if i can find someone locally that can do it, ive found a free software called HUD ECU Hacker that supposedly works with rongmao ECU-s (which is what i have) but im still new to this so ill have to figure out what kind of OBD connectors i need
@@StupidBlokeStupidVideos its also really annoying because most people with euro 3 and less can just jet their carbs which is much simpler than messing about with an electronically controlled carb or an EFI (in my case)
@@acegik7157 if you find out let me know, I’m shit at computer stuff though.
Thanks for the info, will do this to mine and enter it into next year's TT
Mark Stott be careful, you may find the power hard to handle
@@StupidBlokeStupidVideos pffft, I had a go on a Peugeot speedfight once, I think I know what I'm doing!
Mark Stott you mean a Peugeot “Speedfighter”?
@@StupidBlokeStupidVideos nope, definitely a speedfight.
Mark Stott used to work on them all the time but don’t see many these days. Everyone used to call them a “Speeeeeeedfighter tooo mayte”, so I just thought that was what they were called 🤷♀️
Good man I'll be scraping my self down road in no time
Be careful not to flip the shitter
@StupidBlokeStupidVideos will do, also I didn't do the last thing because I didn't want to be cutting things off, and I used metal ball barings in the pipes.
wondering if you could help me i have the same bike as this but a 2020 one and there no wire coming from the variator caseing is there anything else i can do to derestric it
Have you done the carb already? Some models don’t seem to have the speed sensor from new.
I got a lexmoto echo 50cc 2018. Would taking the carb plastic parts off increase my speed?
Which plastic parts?
have the exact same bike, lexmoto echo 50cc, tried to do this today and the washer behind the variator seems to be welded/ tight fitted on. Is there any way of getting a little bit more speed out of this bike without grinding the washer off? even if it is only a few mph extra
thanks
This should help it get up to speed faster but won’t do a lot for top speed. You can buy derestricted variators really cheap on eBay though, they can probably sell derestricted slide on its own. Type in GY6 50cc variator and it should be the same as what’s on your bike, but maybe ask the seller to make sure before ordering. If you do de-restrict the variator, doing this mod along with it should have a greater effect.
Mines the same so I'm interested in this
I have a question unrelated to the video, since you seem quite experienced, if i put a 70cc inside my 50cc scooter do i have to buy a bigger carb or is there a way to modify the current one?
Depends how far you go. If you just change the barrel and piston and keep the same cylinder head and camshaft then the standard carb usually works fine and you should gain a good bit of low down grunt. if you change things like the rollers, camshaft etc to move the power higher up the Rev range then then you can rejet the carb, or in some cases you might need to replace it to get the best results.
@@StupidBlokeStupidVideos So far Ive changed to heavier rollers and took out the variator limiter, looking to buy a 70cc kit but im wondering will it even change my top speed by all that much since the ecu is still limiting the revs?
Heavier rollers won’t necessarily give you a higher top speed, it will just speed up the rate the belt climbs the variator and lower the revs until it reaches top gear. The standard rollers should reach the top of the variator/top gear but take a bit longer to get there. The reason for changing rollers is to keep the engine in its torque curve, so if you move the power higher up the Rev range then lighter rollers will keep you in the power etc. No matter how much power you give it, the top speed will be determined by the gearing as long as there’s no electronic restrictor or the engine doesn’t have the power to reach it.
@@StupidBlokeStupidVideos yeah they didnt increase my top speed downhill but riding on a straight road i went from around 35kmh to 55kmh(the ecu limit) since the stock ones were too light and the belt didnt climb up enough
@@bambi992 if you’ve got the power for it, then there is a chance that they sell longer final drives, but I’ve not seen them before on this model.
Hello! I got the same bike but grey. Can i just remove the pipes. Without blocking them?
No, if you remove the pipes altogether then it will make it have even less power.
hi, does this work for yamaha aerox 2018 4t with fuel injection? if not do you know what i can do to derestrict it? ive got a malossi forcemaster 0 and a new variator with lighter weights, but it still breaks at 49kmh.
No mate won’t work for that. I’ve not done one of those yet so not sure what’s involved in doing one.
@@StupidBlokeStupidVideos ok thank you for the quick response, will just wait for my ecu to arrive
Hi Can a 2022 Euro 5 injection fuel set up be de-limit the same as this thanks you any info.
No I don’t think so. Euro 5 is electric injection. I’ve not done one of those yet
Hey mate, thanks for the informative video. I tried the BB method on my Peugeot Speedfight 4 scooter (50 cc 4 stroke), didn't notice much of a difference even in accelaration, top speed didn't increase either. The variator restrictor is removed and it goes 31 mph max, any suggestions on how I could make it faster without a 70 cc kit? I guess that's the best this scoot can do to be honest 😂
Hi mate. There’s not a whole lot you can do that’s easy or cheap. The bb method usually does work though but won’t gain top speed. Some models have 3 that need blocking. They have another line coming from the inlet manifold to another solenoid valve. Make sure yours doesn’t have that too
thats because its restricted via the ECU
Hello
I got a Neco One 12 2021, any ideas how to derestrict or what type of cdi is needed?
If it’s a 2021 it could be injection. If so then the only way is to reflash or replace the ecu
Great video. didnt know you could do that. Is it noticable when its derestricted ?
They will never be as fast as the old 2 strokes etc, but does make a noticeable difference.
@@StupidBlokeStupidVideos is it easy to notice in sound or anything that makes it suspicious
i tried to get rid of the speedsensor on the back variator, but it just stoped at 15kmh
I’ve done a few and never had that issue before, so it gets to 15kph and won’t go any faster?
If I close these pipes, then I have to buy an ecu and the engine will be 80? Because when I bought the ecu, my engine was choking and it didn't move.
Which ecu did you buy? If you fit a derestricted ecu then you shouldn’t need to block the pipes off. The method in the video is showing how to derestrict it a much as possible for free.
How would i go about derestricting my lexmoto nano 2018?
Depends what system is on it, possibly the same as this.
Hi mate, is this legal and will I pass the MOT with that? Cheers
It’s not part of the MOT test, and won’t make any difference as far as MOT goes. If you’re 16, then technically it’s illegal but you’re extremely unlucky if you get caught out. In my opinion, these bikes are more dangerous when restricted than not!
I had stuck float but did it the mx cheat way and flipped it lol but I was gonna open the top but opened the screws and did em back up cos I’m a cheat skate lol
if it has the washer do you remove it and it’s derestricted?
Usually yes. Some have the washer built into the variator slide so a new slide is needed or it needs grinding down to size, and some have a cage around the back of the variator held on with 3 or 4 screws that does the same thing.
My GY6 with rear wheel speed sensor unplugged actually caused check engine light to flash and cut engine on off so unridable as the ecu needs to see a speed ( I assume speedo or rear wheel sensor etc)
Mine is a China Znen Revival but regardless the ecu needs to see speed or it cuts spark to stop it reving as it assumes the vehicles not moving
Some of them can do this. On this one’s I have ground off some of the pickups on the clutch drum so it sees that it is spinning, but thinks it is spinning slower
@@StupidBlokeStupidVideos I wonder if removing 1 or 2 would help see it slower - then blank off or just replace with generic GY6 carb...
Other thing is change flywheel carb and wire in a stock CDI......
I bet I can make a patch lead from ecu plug to CDI etc change carb do away with the euro 4 nonsense i’m in New Zealand anyway
@@nct9466 I have done that in the past and it has worked, took either one or two of the pick-up lugs off. Also, the ball bearings stuck in the vac tubes actually block off the euro 4 part of the carb.
Hi mate old video so not sure if you’d reply, but have any idea how I de restrict a lexmoto nano, from what I’ve heard it essentially has the same engine as the echo but not 100% sure, and as it’s a euro 4, is there any way of replacing the carb with a none electronically controlled one or would this not work ?
If it’s the same carb then this should work in the same way pal
@@StupidBlokeStupidVideos yeah it’s the same carb and I’ve blocked the holes, I’m just wondering if it’s possible to swap the dellorto electric carb out for a mechanical race carb to up fueling , or does the bike require the dellorto electronic carb
Did you ever try it ? I got the nano but so sick of how slow it is had any luck with it
The ecu needs to see the input from the throttle position sensor to adjust the timing so a standard carb won’t work without other mods. I’ve done this method a few times and it does work, on some models there is an electronic restrictor I haven’t managed to bypass yet so it will only do 30mph before an over speed code but you should still get better acceleration and up hill speeds at least.
Hello mate need help unrestricting my piaggio zip 50 4t 22plate have changed the cdi but has changed nothing
Is it carb or injection?
Hi mate I have a 20 plate echo , I can access the 1st pipe but not the other one ,
It should be there. Look for the solenoid valve and follow the pipe back to the carb.
Hi mate I’m looking to get my first 50 in a month or so what good value under £900 bike do you think I should get ? (Keep in mind I want to derestrict it), thanks.
Hi mate. The best ones for being fast in my experience are the piaggio engine models. The aprilia sr50, nrg, even the air cooled ones like typhoon etc are pretty quick.
Anything 2 stroke if ur after top speed 4 stroke if u need reliable n are happy at 35-45mph
Hi mate on my 2020 Lexmoto echo 50 the speedo says I’m doing 40/42 but when I put my phone gps speedometer on it said I was doing 33/34. So I disconnected the Speedo. Is there any way to get my top speed higher than 33mph
Thanks
They’re not a powerful bike to be honest.
@@StupidBlokeStupidVideos fair enough mate 😂
I cant find parts (Variator Kit) for my Lexmoto Echo 50cc E4 5-Litre anywhere in the UK. I've been waiting for months. Its so terrible. Does anyone know where to buy one, other than CMPO?
Is your variator definitely restricted? It’s just the front variator thar you need, I’m not 100%, but I’m fairly sure that the standard 50cc GY6 one will fit. Worth a try as they are only cheap, CMPO should have them but failing that, eBay will have them too
Thanks for the very quick reply! I guess it’s worth trying... from the reviews on on trust pilot people have been waiting 3-5 months at times for parts. I will try. Thanks again!
@@HOOKZIE no problem mate.
Does this work with direct bikes panther 2023 sooter ?
I suspect that the 2023 model will be an injection bike. If so then no, but it’s worth having a look as if it is this setup then it should work
Does this work on the 2023 lexmoto diablo??
Depends what setup the bike has, but possibly
Hi I’ve got a AJS Firefox 50 2020 euro 4 what exactly do I need to do to de restrict I know I can buy a cdi but it’s £110 for my bike and I only paid £350 for the full bike so wanting the cheapest or even free way of doing it
Has it got the same type of carb on as this with the pipes coming off it?
@@StupidBlokeStupidVideos yes exactly the same going to be doing what you’ve just done to see if that does anything but not sure what else to do as I’m on a tight budget
Hi mate looking at mine cdi dereistict seems cut , doesn't make much differnt get like 35, thinking of getting 72cc big bore kit would that make a difference
Is it a euro 4 model with the electronically controlled carb? The speed restriction wire being cut on its own will let it go over 30, but you usually won’t have the power to much more unless you’re going down hill and won’t make any difference up hills unless you derestrict the carb too. There’s another video on the channel on how to do that if it’s not a euro 4 model.
Big bore kite make a noticeable difference, especially if set up correctly.
@@StupidBlokeStupidVideos not too sure what one mine is mate its 16 plate so it's the older model and I thought the same but even down hill it's the same speed its odd
@@StupidBlokeStupidVideos yeh definitely going to get a garage to fit it soon enough so il let you know when it's done
Can you do the thing where you take the washer out ?
If it has one then yea, some do some don’t.
After blocking the airways do you have to do the rest or can that make it go faster ?
Depends what other restrictions are fitted. Just blocking the vac lines will stop the automatic throttle restriction, so should effectively give you a bit more power/torque. If there’s a rev limiter, speed limiter or the gearing is limited then it will potentially not have any faster top speed without removing the other limiters, but should get there faster/be better on hills.
@@StupidBlokeStupidVideos ok thanks! And also I’m trying to move the kit start piece and there’s a different type of screw that I don’t know how to take off which tool did you use for that ?
@@baitetc2088 some of them have 2 tamper bolts diagonally if I remember right. Like a star with a pin in the middle?
@@StupidBlokeStupidVideos yes that’s the one
@@baitetc2088 yea it’s called a tamper bit/tamper torx bit.
Can you derestrict the euro 5 scoots the newer ones do you know
I’ve not done one of those yet but I suspect the injection models will need a remap or replacement ecu
I am a 125cc scooter bike if I put on a big muffler do I get more speed or mi might get less speed just let me know what to do plz
You’re just likely to get more noise on a 125 4 stroke.
@@StupidBlokeStupidVideos so what can I do to get more speed
@@shannonmcleish31 most effective for the money is probably going to be a bore kit, but there’s usually no cheap and easy way to make a 125cc faster.
Dose it work on the echo 50 e4 models
This is an e4 model. Some are injection though, it won’t work on injection models.
Hello SBSV, I have a lj50qt-6l (Echo + 50) from 2019 and this type of engine does about 15mph (not great). I have a Dell'orto ECU with only a vario restricted Bus (bigger edge on the vario bus). So should i get a new ECU to get it unlocked for full rpm and full speed?
Have you blocked the vac lines?
@@StupidBlokeStupidVideos not yet... But iwould be restricted inside the ECU? The vacuum lines have two solenoids on it.
@@schoonbeek2 the ecu restricts the carb via the solenoids. You won’t necessarily gain top speed by removing them but usually get better acceleration and up hills. At 15mph yours sounds like it may have other issues though
@@StupidBlokeStupidVideosthank you for your reaction 😊 My mopet is a restricted version in the NL. You buy them straight out of the shop 😂 they go as fast (as a bicycle). Sometimes electric bikes can keep up with me.
But why are they on it? It has something to do with emissions? I don't get the whole tube solenoid construction thing :P@@StupidBlokeStupidVideos
Hi mate, excellent video. I unplugged my speed sensor and my EML comes and and the scooter won’t go past 20mph. EML is flashing. I then plugged the speed sensor back in but turned it round so it couldn’t pick up the speed and it was still stuck at 20mph with EML flashing. Any ideas bud? EDIT: putting it back how it was bike goes back to 28mph like it was before
I’ve not had this issue before but sounds like there’s some kind of anti tamper on the software. How many speed pickups are on the clutch bell?
@@StupidBlokeStupidVideos hey! Thanks for the reply. It’s back together now but I think there was 4. Pretty sure the CDI is restricted however as online place that sells my scooter advertise a restricted version and a derestricted version and in the parts section they sell derestricted CDI’s so for £30 shipped might as well give it a go. But yeah, unplugging the wheel speed sensor restricted it to 20mph with a flashing EML which sucked. Great video however, I blocked the 2 pipes to carb (mine had mini tiny air filters on each end next to 2 solenoids) and now it accelerates much quicker at least so thanks for that bud!
@@a1d3nh0 yea the carb mod won’t adjust the top speed if it’s on a limiter, just acceleration and hills. If a de-restricted CDI is only that price then it’s worth buying, but the ones I looked into buying when I made the video were much more expensive. Make sure the ECU you get is got a euro 4 model and not the older CDI which just controls the ignition and and not the carb. I was going to suggest putting the speed sensor back in place and grinding half of the pickup lugs off if there’s more than one, so the ECU still gets a signal but is tricked into thinking the bike is only going half its actual speed.
@@StupidBlokeStupidVideos damn, man. That’s an absolutely excellent idea! I would never have thought of that. Cheers. If this CDI doesn’t work I’ll give that a go. Thanks for your time mate. Have a great weekend

It doesn’t always work, but I’ve got round this in the past by grinding half of the pickups off the clutch bell so the ecu only sees half the speed you’re doing, but this only works if you have multiple pickups
I have only 1. I think i want to buy unrestricted ecu but its expensive

Got an echo 20 plate and its not got the washer on but tops out at 30 and I’ve tried the bb bullets and It didn’t do anything
The BBs will only allow stop the restrictor that stops the slide of the carb from opening fully, but the top speed restrictor works in a different way. The BBs themselves won’t raise the limited top speed, but should help the bike get to it quicker and be better at going up hills etc. There are a few ways euro 4 scooters are restricted and some harder to get around that others. Does it have a speed sensor on the clutch drum?

This video shows you how to stop the ecu from restricting the carb side which is the main/power restriction.

Can you open variator
Variatiors can be opened up yes. Some of them have a removable ring in them to restrict the gearing, some of them the ring is built into the slide and can’t be reminisced without grinding it off. Many newer ones have an electronic restrictor instead of restricting the gearing though.

Hello mate wondering if this will be the same steps for a 2019 4 stroke 50cc sinnis jet 2? Thanks
The carb, more than likely yes. However don’t disconnect the speed sensor as it will probably go into limp dick mode and will lose power. If you just do the carb then it likely won’t go any faster full speed, as the max speed limiter will still be in place, but you should get better acceleration/speed up hills.
@@StupidBlokeStupidVideos is there not a washer on the bike to remove? Well I’m guessing if there was and I did the bike still wouldn’t get any faster ?
@@WX04 if there is a washer then yes remove it as that’s a restriction of the hearing, effectively not letting it reach top gear. Most of the new ones don’t have a washer though, and are electronically restricted via a speed sensor on the clutch bell. Some you can disconnect it, but others will go into limp mode with it disconnected.
@@StupidBlokeStupidVideos for the speed sensor could i just buy a derristricted CDI from ebay or something?
@@WX04 it’s dependent on what system your bike has. If it’s euro 4 then they have an ECU with an electronically controlled carburettor etc. A derestricted one is expensive. If it’s just a normal CDI then a derestricted CDI won’t gain hardly anything without doing the other physical derestrictions.
Arite mate.
I bought a 50cc echo plus want to derestrict it. Mine looks exactly the same as yours, same colour as well. I was told they can't be derestricted.
What did u say the balls do wen u block it?
Also where can I get hold of those balls?
The balls are just ball bearings from a kids BB gun. The balls stop the electronic carb restrictor from operating.
Cheers geez
@@moukbu4235 did it work
@@kopegoat1641 na the variator ring is welded on. Need to use a grinder maybe to cut it out..
Yea if it’s still got the variation ring on, this mod will probably only make it accelerate a little bit faster but won’t affect top speed. Will make more of a difference once the variation restrictor is removed.
What moped makers don't realise is how dangerous unrestricted moped's are on national speed limit roads and pulling away from traffic lights but by law they have to be restricted if you have a provisional license. Piaggio's are much easier to derestrict as it's more mechanical.
Very true, I couldn’t count the amount of times ive been overtaken in stupid places on 30 roads because of the restrictions
@@aegg9915 give it a rest and could say the same about cars
Obviously you've been beaten too many times, playing traffic light grand prix, by 49cc mopeds. 🤡
Hi, I've just done exactly what you showed in the video and it's derestricted now, it goes 42mph but, lost a lot of acceleration. A hill start is a nightmare. Feels like driving off in a car in 2nd gear. Any ideas? Hill starts are terrible. Lexmoto Echo Plus 2020.
I thought putting the bb's in will fix it but it only made it get from 35 to 42mph faster than before. Another thing to mention is the back wheel is constantly spinning when on centre stand even after warming up and riding it.
Have you taken the variator apart? The BB in the pipes won’t mechanically affect the drive, and should also improve acceleration throughout the rev range. It sounds like a drive issue, as in you’ve not put the rollers back in properly or one has come out possibly.
@@DjSunshine07 hey mate was ur variator ring welded on? If so how did you remove it
@@StupidBlokeStupidVideos managed to fix it by decreasing the idle speed. Back wheel wasn't spinning anymore at idle.
@@bayleyclarke7513 Mine wasn't wielded in. Just had to pull it out. Heard from someone that u could either heat it up or try and cut a portion of it... I am terrible at mechanics so try and look for someone who removed a wielded one to see what they done. Sorry I can't help.
Hi how do you want u do it on a neco gpx 50 2 stroke
More than likely in the exhaust and the variator on that one but not 100% sure.
Would getting a new exhaust make it go abit faster
Sym fiddle 3 49cc 4t, i remove ring and now run 50 km/h,but whe is on this speed it doesnt run clear and smouth, something is going wrong, and a noise appears on 50.....for more speed another cdi or can i remove the wire from original cdi??
What year/setup is the bike? Is it hitting the Rev limiter? Or it could be hitting an electronic restrictor? Fitting a De-restricted CDI doesn’t actually usually have that much of an effect compared to the other restrictions.

The washer?

@@carljefferies6916 if you can get it off then yes take it off, but it’s usually cheap enough to buy a non restricted variator than struggle removing the ring.
@@StupidBlokeStupidVideos hi I have a 50 gy6 lexmoto Vienna 2016 is this a euro 4 ? Iv fitted a 100 kit to it pulls really well now but can’t seem to find a way to de restrict it any help would be much appreciated thanks 👍
@@pikiejohn how fast goes it max at? I doubt it’s a eu4 on that year. The car will likely have a throttle stop on it as I show on another vid on the channel, and the variator a washer in it. CDI rev limited too usually but this one isn’t as restrictive as the others
I tried to take off one of the pipes you showed at around 2:20 but it starts to rip when I try and pull it off, what should I do?
If there’s any leaks on the pipe it’s gonna cause issues. Maybe cut it close to the carb if it’s already damaged then get the rest off the carb by pulling and twisting and the put the good part of the pipe back onto the carb once blocked with the ball bearing
@@StupidBlokeStupidVideos are you sure it'll be alright to cut off a little bit? i dont wanna cut any off and then its too short to put it back on
@@Evasi0m should be ok as long as you don’t take too much off. If it’s not already ripped then you could follow it to the solenoid at the other end abs block it there instead. It doesn’t even need to stay connected to the solenoid, you could just blank it and leave the other end disconnected
@@StupidBlokeStupidVideos ahh right i didn't think about following it to the other end, i'll definitely try that. do you know anything else that'd block it cause i dont have any little bb's like the ones you have
Good stuff,, so would that be same for a katana 50cc, 07
No mate. Katana is an old 2 stroke, brilliant Bikes and much faster than these when derestricted. The exhaust and the variator is usually where they are restricted. In my experience they respond well to a sports exhaust, variator washer out and lightened rollers.
You can turn your hand to owt mate 👍👍
I can fix anything, not very well.
@@StupidBlokeStupidVideos you do a half decent job 🤣🤣
Does it work for znen r8?
I’m not familiar with that one but as long as it’s in the same carb setup as this, then it should
@@StupidBlokeStupidVideos 2:19 the thing you pulled off doesn’t have the metal thing. And im pulling on it and i think its just going to snap
@@jarnamadurinn you mean the little pipe? Some of them don’t have the metal clips. You can follow the pipe and disconnect it from the solonoid valve at the other end and block it there if it won’t come off but it should come off. Be gentle and maybe warm it up with a hair dryer if it’s tight
@@StupidBlokeStupidVideos yeah i did it, but it didnt do anything. I need to get a derestricted ecu but i dont know where i get them to match my znen r8
Anyone know where the indicator relay is on these
Some are under the seat, some next to the battery. A lot of them are under the front panel though. Just going off Chinese scooters in general.
@@StupidBlokeStupidVideos front panel is only bit I aint had off yet so that narrows it down. Thanks alot

Where do I find the deristricted ecu
Can’t recall the website but seen them online, they’re about £180 last time I looked for one though.
ive got one
Is it safe? To do it?
I’ve derestricted many 50cc scooters, most of them the older style carb but some of them with this style. Never had any issues.
@@StupidBlokeStupidVideos Ok! But do u have to Block both of them with the bb gun ball or just the one u did?
@@fax2000 I did both of them, follow the vac lines and block the ones linked the the solenoid valves. It works by the solenoids opening and releasing the vacuum above the diaphragm that pulls the slide up, thus dropping the slide/closing the throttle. Don’t block the wrong one though, eg blocking the carb vent which is next to one of these pipes will likely cause issues and stop the carb filling properly.
How fast can it go now
This procedure is more about gaining a bit more acceleration/power up hills than top speed.
Mine does 45 and accelerates quicker
Yea as mentioned, the blocking of the vac lines to the carb is more for acceleration and hills. Top speed is usually governed by the variatior or a speed limiter which this bike didn’t have.
I have done this now my bike won’t start
RtX x FuRY you’ve done something wrong then. Check you’ve not knocked any wires off whilst taking the seat bowl out.
Also make sure you’ve not blocked the carb vent pipe off instead of the vac line on the airbox side of the carb. It’s next to the choke, if you block that the carb won’t fill with fuel properly.
Didn't work for me. Gives me 23 mph tops
It should do more than that without being derestricted. Sounds like it might be broken
I need help 🤣 cannot get the casing off
Which casing?

@@sonnyshepherd8158 did you get it off?
Its just like watching Guy Martin ,,,,

It doesnt work the bike will just cut out as soon as you start it
You’ve done it wrong then.
What bike do you have and have you definitely not blocked off the wrong pipes? If you block the wrong pipes, you could cause the bike to cut out. I work in a motorcycle shop, and have done this many times.
@@StupidBlokeStupidVideos i done it but not your way they were defo on the right pipes. As if you block the vacume of the carb you will stop the flow of fuel hence why the bike cut out
@@matrixgaming5651 this isn’t the vac line that opens the fuel tap. You may be thinking of the older type carb.
Cant you just take out a cable in the ecu?
Not on this model
Can you do a video where you show how to unplug the restrict from the variator

That shouldn’t happen. Sounds like you’ve done something wrong there to be honest. All the bb bullets do is bypass the electronic carb restrictor.

Completely different process to derestrict the 2 strokes
100mph off a cliff 😂
I’ve carefully calculated the terminal velocity of a falling Lexmoto Echo 50 on earth, and my guess is 99mph.
@@StupidBlokeStupidVideos 😂
I tried all these RUclips videos to make a 50cc scooter faster. NONE OF THEM WORKED very well at all. 6MPH isn't even noticeable. I spent maybe $200US and just built a 100CC engine from Italian Vespa GY6 parts. Now my little cheap Chinese scooter (Euro 4) hits about 65-ish.. Up hill is no longer a problem. Everything is cheap for a scooter. Entire engine is less than $300US. So forget all these "make your slow scooter faster" videos.. they are ALL pointless. Spend the money for a real motorcycle or spend a little money and build a more powerful GY6. Who is going to check for emissions on a vehicle that you do not have to register? No one ..LOL.. so get rid of all the emissions junk. BTW: Chinese parts are horrible and will not last under constant usage.
You’re missing the point a little bit. 50cc scooters, in this country at least, are restricted. This is just about removing that restriction and giving the bike back the power it was initially designed with before the restrictor was added to meet rules and regulations. What you’re talking about is tuning/modifying, which is a different game altogether. You’re obviously going to gain much more by modifying than just derestricting, but it’s much more involved and expensive. This is easy and costs nothing to do, and it does make a noticeable difference to the performance of done correctly.
Hi, i have an yamaha aerox 4 stroke 2019 50cc would you know how to derestrict it ?
