How to derestrict a 50cc scooter / moped Make it go Faster

[@rsrbob]

Moving the clip up moves the needle down so the thicker part of the needle is in the needle jet leans the mid range out. At full throttle the needle position is insignificant. This would only help if the mixture were rich through the middle. Unless you are correcting a defect, you cannot add more fuel to the same airflow and increase performance.You still need to maintain the stoichiometric air to fuel ration of 14.7:1. The main jet meters fuel flow at wide open throttle, which if you are seeking top end, that would be the area to focus on, IF you increased air flow through the engine.

[@safarijonas3490]

Thank u!👍

[@JiggyPapason]

Right on!

[@James-xb1zm]

Changing the needle jet setting will primarily change mid range jetting. The main jet will control the mixture at full throttle, and should be the starting point for tuning the carburettor for optimum performance. Once the main jet is optimised, the needle jet and pilot jet's should be adjusted to achieve the correct mixture at different throttle openings.

[@MR-rp3xr]

The needle is moved to the middle (third groove ) from second groove from the bottom as standard on most carbs before the the carb was running rich to add to the rev limiter

[@brittneymckenzie4865]

Your advice worked!!

[@Derek_S]

My wife used to have a Yamaha CW 50. When it needed a new exhaust for the MOT, they installed one with a larger hole on the manifold flange. Just doing that increased the max speed to around 40MPH. We didn't touch anything else.

[@James79561]

All you did by moving the clip on the needle up one is lean the engine out which makes the engine run hotter and wear quicker. DONT DO THIS !! Placing the clip in a lower position raises the needle enriching the emulsion tube with more fuel and makes the engine run richer. This setting allows the engine to run cooler .The video is sorry and it's incorrect info. Do the research and get the facts. NEVER use a electric driver on carb screws !!!

[@marvelaturraz5405]

Isn't it incredible that this guy is telling over 280K people (so far) completely bogus, screwed up info?! He doesn't even know that it's called a needle valve. How many people have ruined their scooters by doing this? Jeez... As you know, James, your assessment is 100% accurate. I'm just seconding what you said. PEOPLE, DON'T DO THIS! If your engine runs hot (which it will be inclined to do by dropping the needle) then you'll probably end up blowing the thing up, and that would be a shame. Snip the restrictor if you must, but leave the needle alone!

[@James79561]

[@lamboy1098]

Moving the snap ring up on the needle like shown will seat it further into the main jet channel, that restricts it, moving the snap ring down towards the pointy end allows more fuel to flow.

[@RIMHQ-YT]

Exactly,I was like wth is he doing. Lol

[@chancergordy]

So how much was the scooter slowed down when you weakened the mixture by putting the needle further down into the needle jet? So if you are reading this then remember that the needle is tapered, the further up the circlip is , the lower the needle sits in the needle jet, the wider the needle taper into the bottom jet, the less airgap for the fuel vapour to be drawn up. Therefore the less fuel up into the venturi intake. The smaller the bang, the less power out. Oh dear!

[@m.g.540]

Exactly! this nimrod leaned it by moving the clip up, it's a CD type carb the needle needs to move up so the clip needs to move down

[@nicholascgoss]

As a mechanic I can tell you that A) more fuel does not mean more power. It just means your running the engine richer, it will use more fuel. B) more importantly you move the clip UP making the needle longer (lower position) and closer to its seat and therefore your running the engine leaner not richer. On 2 strike engines running the mix too lean can cause permanent damage to the piston and other components. Please do t follow the advice he’s giving with the carby. As for the wire that he carelessly cut instead of just removing from the plug, I’d want to see more information about what it is, how it works and what are the consequences of removing it before doing that. There is a reason why highly qualified engineers do these things so removing and cutting “this black thing” and “that metal thingL and “the yellow thing” and “this bit” etc is a great way to quickly end up with a bike that needs expensive repair work.

[@grazz7865]

From what I understand, that’s the reference wire that tells the CDI when to fire. With the wire cut, how will the CDI know when to fire the plug or advance?

[@grazz7865]

I want to see a before and after video because I can’t understand how the bike runs with that wire cut. There are 5 or 6 wires depending on the set up. One or two grounds, power from the stator, kill switch wire, wire to the coil and the pick up wire. You’re cutting the pick up wire. The only wire that tells the CDI when to fire.

[@daz3434]

Absolutely spot on mate 👏 Well explained.

[@techmaven5900]

You dropped the needle lower by raising the clip...that would allow LESS fuel.

[@tnroyal3778]

I thought I was the only 1 thinking that

[@mrpowdercoater]

[@noberts2k9]

yes the clip needs to be lower also I don't see how that would make it go faster

[@chancergordy]

Correct!

[@novacain7971]

bigger explosion? ??

[@patthewoodboy]

revs are controlled by the CVT clutch spring and rollers, cutting that wire just removes the speed sensor from the loop. You also need to pop out the restriction plate where the rollers are , doing that lets the scoot do about 38 mph on the flat . Dont lean off the mixture like has been done here , engine death :-)

[@scriptles]

Sounds pointless, as stock I can already hit 40mph+ anyways on flat ground. What I find helps increase speed without mod is to back off full throttle to the point you are maintaining your speed then SLOWLY give it more throttle I have gone over 50mph/80kmh on flat ground on pure stock no mods. If you are getting only 38 you are doing something wrong.

[@patthewoodboy]

@@scriptles yours isnt restricted. Mine is a chinese engined scoot with only 2.8 horse power so 38mph is all it can do

[@scriptles]

@@patthewoodboy Mine is 1.8 horse power according to the title. Both my old Tao Tao (ATM50-A1), and now my Denali (yongfu) had no problem hitting 40 mph but only if I ease off the throttle and gently ease into it. If I just max out the throttle I barely hit 20-25. Pretty sure both of those are also chinese scooters and the translations in the guide are poorly written. Like "cer tain" shouldn't be 2 words and "outtak" should be exhaust or at least spell take right when they spell intake correctly. ect.. Upgrading the Tao Tao to 100cc with the big bore kit let me do about 40-50 mph (up to 80 kmh on the speedometer). It might not be restricted I never checked to confirm.

[@GWAYGWAY1]

The same bike sold in Europe has no restriction , it seems the exhaust has a restrictor plate and throttle restriction as well as the limiter.

[@JesperValentine]

Only if the response in PART THROTTLE is not as desired, you move the clip UP on the needle to get LEANER and DOWN to get RICHER. So in this example you will get LESS fuel so it will get LEANER. Its best felt by erratic engine behaviour at part throttle: If its hesitating at part throttle, you need to get richer - move clip down one ring. If its 8-stroking (or 4-stroking if a 2-stroke engine), you need to get leaner - move clip up one ring.

[@oxaile4021]

Ok let me get few things straight for you who have never worked on your bikes 1.look for info about your bike on internet, you will pretty much always find out what is restricted what is worth doing and how to do it 2.if not necessary do NOT modify stock parts, you might need them someday and the resell value is a lot higher. Usually aftermarket parts also give more boost to your bikes performance 3.Carburetor settings. Extremely important especially on 2 strokes. always adjust your carburetor settings after modifying your bikes performance. If you don't do this you will have really high chance of blowing up your engine + you won't gain the max performance you could be getting.

[@Sagatta32]

"always adjust your carburetor settings" what do you mean by this? I think this is safe.

[@fritzkunkeljr4531]

I have worked on 18 types of scooter from tao tao, kymco to Jl50qt-6 . Every CDI wiring I have seen has a red/black wire, yellow/black, blue/white, white/black , green/white and green. I have never seen a pink wire anywhere on a scooter.. Now the green/white stripe is called a trigging ground. It act like a rev eliminator. You can do away with that one. But must scooters don't even use it nor do they have a wire plugged into it.. know your facts before making a video and looking like an dumbass.

[@nickolaswoodswoods2472]

Buddy of mine races these things, the best "cheap" way to go about adding 10mph is to Port your intake hole on your head, then cut about 1/2 inch off the access plate on your clutch ON BOTH SIDES so it's even, and then run them on alcohol injection systems. He's doing 65 on a 50cc the clutch shave allows the engine to reach a higher rpm before engaging and thus a faster acceleration. Porting the intake allows for amazing overall fuel flow into the cylinder and actually added roughly 4 hp!

One recommendation that I would make for ANY moped new or old is to adjust the valve clearance to the factory settings. I have a 2013 Kymco Agility 50 and just adjusted the valves to the factory specs of 0.051 mm and it has more power than it ever had from the factory. Sometimes these scooters leave the factory with valves that are not adjusted properly. The difference was significant.

[@mrRhwalden]

The needle adjustment has the most effect on midrange power. Jetting is more important to proper carb tuning on full throttle runs. If the scooter acts bad at part throttle, then it's time to adjust the needle. At part throttle, If it hesitates but then cleans up when you let off the throttle, you're lean (move washer towards longer side of needle). If it just hesitates and doesn't clean up when you let off, then it's rich(move needle toward shorter end of needle)

[@sladesmith1221]

I surmise you yourself couldn't have done better. Maybe you sir should sharpen your perception skills. This man is giving sound, monetary advice. School up son! 🤣

[@hansjoubert]

The needle mod you did will make the carb leaner... If you want it a bit richer the clip needs to go lower, making the needle move up a bit. That will increase fuel to potensially increase combustion

[@TheIamtm7]

What if use use change the CDI to a high performance one with no restriction. Would that in theory make your scooter faster without damaging it. Any advice on this will be appreciated. Thanks in Advance.

[@Dwainpipe21]

lifting the clip one notch on the needle will weaken the mixture meaning more air less fuel rather than making the mixture richer,more fuel less air which could cause the ped to run weak on 2/3 throttle to full throttle as that is when the needle / main jet have most effect which could cause the ped to seize so not a good idea. Unless you have changed the exhaust, intake etc there should be no reason to lift or lower the needle or change the jetting of the carb It WILL NOT GO FASTER!. The main restriction in a ped is in the cdi (rev limiter/timing advancement), exhaust (restricting washer) and variator(a washer/ spacer which stops the pulleys from closing right up which stops the ped from reaching a high enough gear so it just revs out)

[@Eqoob]

+Dwainpipe21 Hi, I saw that you know something about the functions of the scooter and I would like to ask you if you maybe know which is the optimal ratio fuel/air or in other words, I put on my 50cc 4T a 72kit and upgraded also the main jet first from 85 to 88 and went better and then to 92 and goes even better but when I am in mid-mid/high throttle it bogs for an instant as it doesn't get enough air but then accelerate good... I tried various combinations of head valve settings and it helped a little, but the "bogging" when I go 50-80% throttle persists... do you think that I need a larger air flow, so a carburetor with a larger air intake so the fuel gets enough air to explode properly?

[@countryboy131984]

turn your mixture screw from full closed to 3 and a half turns open and that should help some if not then try getting a Klein carb they are cheap on Amazon

[@jimcook3448]

Many changes to my 50cc (which now has a top speed of 55mph). However, cutting wires & messing with the needle valve wern't part of my changes. These shortcuts will probably get you an extra 2mph and send your scooter to an early grave................ NOT RECOMMENDED.

This just seems like something that going to bit you in the ass eventually. The pink wire is there to stop you from over revving your scooter and doing damage to your motor. In most cases this only limits your top speed when going downhill, as on flat ground most scooters don't have the power to hit the rev limiter. So please people watching this, keep your rev limiter installed it's there for a reason. And second. Adding fuel isn't going to do much if you don't increase the air flow to go with it. All that going to do it make your scooter run rich, have worse fuel economy, and in some cases depending on altitude and air density, actually make your scooter slower and run like shit. If you want to make your scooter faster, you're going to need to do actually engine and part upgrades. Little things like this almost always come with a nasty compromise somewhere down the line.

[@gemjab5337]

thank u for that so I need to upgrades to the engine I wish I had a partner who has a moped

to top it off moving the needle washer up is going to cut down fuel flow (lean it down) washer to the bottom is max fuel, higher rev with less fuel is not going to increase speed thats for sure

Actually the Rev thing whatever it is, is put in factory to limit your moped to 35mph because it's illegal for a company to sell a 49cc moped that goes over 35mph, it won't damage anything it's just there to keep your bike at factory speed 😊

if you move that lock ring up, it will run leaner, what means it gets less fuel at mid throttle.. so you changed the needle in the wrong direction. also normally you just change the main jet, so the scooter gets more gasoline at all throttle positions. when moving the needle it gets more gasoline mid throttle but the same amount as before at full throttle. i highly advice everyone to not mess up their carburator adjustments because of this nonsense video. you really should know something about these engines and adjustments before you make an tutorial to youtube..

You're better off installing a bbk, aftermarket carb and exhaust, and changing cvt rollers, otherwise derestricting alone will not do a whole lot on a 50cc. You'll also want to richen, not lean out the air/fuel mixture. These things will still run cheaper than buying a larger displacement scooter.

[@TheGingerMechanic]

in some situations running leaner will improve performance but this needs to be diagnosed by carrying out a "plug chop" but that will indicate information about the main jet the needle is just for the introduction of fuel from the main jet to the engine so leaning it off without main jet alteration will just cause it to pick up well until its at full throttle then it will just overfuel (like most of these mopeds do)

[@therobb5738]

My needle doesnt have those adjustment grooves. Not sure if mine has that pink wire, either. I'll cut it if it does. I have no fear of blowing this thing up; I've already installed NOS on it. Right now, the carb isn't letting gas through, even though ive rebuilt it twice and installed all new fuel lines and cleaned out the gas tank. It'll run on starting fluid, but wont start on its own fuel, no matter how long it cranks over. So, for me, it has to run first before it blows. Good video anyways, thanks! Watched it twice now.

[@PIchillin456]

I should have mentioned the benefits. Properly adjusted valves will keep the engine running as efficiently as possible which means better fuel economy, increased power and torque, slightly increased top speed (assuming that the scooter is deresricted), better throttle response, and the engine will typically be easier to start.

When you raise the clip on the needle your leaning out your engine. Might seem like more power but engines run great when lean,..right before they blow up. Keep the needle at the bottom

[@memoal4922]

I have 2 pink wires in my Peugeot ludix 2006 should i cut both

[@npcfrost4564]

just seen you was making your needle leaner... it actually is restricting it and making it slower. not to mention it will make your engine run hotter as its starving for fresh gas. :/ on the contrary move the clip down (raise the needle) it will make it run richer (as long as you open the airbox too) and that will give you power. :D

[@npcfrost4564]

also you can drill another hole on the other side of the needle to allow your slide to get more air as this is a cv carb it opens a butterfly valve with the throttle and needs the velocity to open the slide unlike flat slide carbs.

[@vawndavis7535]

please share more karma where exactly you drill it?

[@jamescollins4465]

[@Tboneangus]

The rev limiter is in the CDI box there are unlimited rev cdi boxes for these gy6 motors they are blue aluminum with fins and an led showing spark, wont make much difference unless you install the bigbore kit with it then you need to re jet your carb. The carbs from china are capped over the fuel / air mixture screw you can drill two small holes side by side and use a small flat head driver and easily twist the little brass cap off. the normal setting is 1 1/2 turns out from all the way in, if you find you need to turn the screw in further then you need a smaller pilot jet and vise versa. You are adjusting the main jet with the needle mainly used to get rid of flat spots in the acceleration both of these adjustments will be different for every one depending on altitude, temp, exhaust size and intake flow, and carb venturi size. Those CV carbs that come stock are crap though with little to no tuning. you can drill out all the screws that are capped off to prevent you from getting in it or just buy the upgraded "so called" high performance carb.

[@trickey57]

So you don't need that spring you lost?

[@chriss4365]

if you want to do it right get a unrestricted cdi box and install gauges with a tach. the cdi limits rpm to 6k so you can't go faster than 35. change it with regular one and you can go at least 45 on a 50cc without going over 8k rpm limit.

[@ZteveW]

It would've been a good idea to ride it at top speed before and after your modifications. I'm not a mechanic so I can't comment but I do know all doubt would be eliminated if you could give us a before and after.

[@rudeboz5486]

proberly only went about 4 mph faster if at all!

[@teddyhuttner2846]

I would like to know if I need to change the carburetor when I put the big bore kit on my 49cc motor

[@spade82mnc]

50-90cc's, stock carbs work just fine

[@ihategoogle7849]

Don't you love when someone comes to youtube to learn about something, and an illiterate douchbag (Carsten) tells him he should do research before asking about it.

[@garystillwell8536]

Move the Ring down, not up. And I don't think that will help much until u put bigger jets in it, also you have to derestrict the air flow and exhaust, and upgrade to a better spark plug.

[@suzukits50xk93]

WOW.. it worked. Cut the blue and the white wire to go even faster. It advances timing and you get more power. You pop wheelies like there is no tomorrow.

[@HaCkErZ931]

Hello. I've just done the bit with the washer as my moped does not have a restricter. It actually has made it faster! Thanks so much. I've always been a slug around my friends... Still am but not by a lot! :)

[@alexlucy8627]

Probably very simpler to the Genuine Buddy 50 (49cc). I'm just wondering during if I still cut the pink wore , haha.

[@iwasherefirst786]

Amazing camera skills and fings

[@bonniej0]

Is that a six prong CDI? Cuz I don't have a light pink.

[@stephenparkinson5303]

Thanks mate, worked a treat. Given me that bit of extra Umph up the hills. - Yeah as someone already mentioned, always disconnect the battery before playing with electrics - Cheers.

[@bubbaselectricsourrebuildo9883]

Can thos be done on a rough house 50cc or only on a chineese bile???

[@Corp0ralPunishment]

lol, be careful of taking technical advice from someone who calls things 'this bit' 'the black boring bit' 'that yellow thing' 'using this' and wouldn't it be the speedo that would send information about whether the bike is standing still? :-(

[@billysuk]

I could have been technical but whats the point. There is to much video on youtube like that useing complicated terminology that the average person dont realy need or care about. They just what to know how to make it faster without all the bull shit. And thats what im trying to do on my channel. And no it would not be the speedo that sends the information. As the speedo is wired to the front weel witch would never move if the bike is on its stand. Nice troll tho hope you had a nice day.

[@drock2267]

billy b dont be mad that you dont know what the hell your talking about.your just trying to make people break their perfectly fine scooters.

[@stewartbell2100]

but surly if your so stupid you really shouldn't give any advice, maybe its a simple case that understanding complicated terminology for the average simply states your average ability to common sense and you really don't have a clue. Did you woke up one morning and from a hunch manged to come up with the dimmest idear you could think of , which in a nutshell is the best you can manage to fuck your scooter up.. DO NOT DO THIS ITS THERE FOR A REASON.

[@NikolaTheLegend]

+BillysUK your advice is as about as good as your spelling

[@subcultureera]

+Stewart Bell YES IS THERE FOR A REASON. A REASON IS RESTRICTION FOR IT SO 16 YEAR OLDS CAN RIDE THE SHIT U DUMB FUK

[@ProudMurican_PVT-GR137]

How many times have you done this? How many times did it work?

[@maline915]

thanks for the laugh ! .. did you ever find and place the spring back in ?

[@natezmoto1793]

Even if your adjustment allows for more fuel, you have failed to address the complimentary air flow which needs to change in order to keep the engine running at all. Fuel + Air = Power... right? Might I suggest a cone air filter if you think you have the fuel thing figured out LOL

[@JesperValentine]

It´s Important that you check your sparkplug after modifying your CDI. Go for a full throttle run and hit the killswitch with the throttle is fully open At FULL THROTTLE, you will need a BIGGER FUEL JET if its white and/or grey - and a SMALLER one, if its black and/or wet.

[@craigfitzybhoy9543]

trying to make my 50cc back to a road legal one. just looked at the pink wire its still connected to cdi. cdi looks the same as your one do you think it may just need a factory cdi installed again but would i still have to mess around with carborrator.

[@raymenke5881]

DOES DRILLING A SMALL HOLE IN THE EXZAUST PIPE MAKE IT GO FASTER

[@jordanparker3184]

Do you have to do the thing with the carb

[@TonyG_1111]

Oh forgot to mention.. I went from 40mph to 75mph because my scooter is now in the back of my pick up truck... Just cut them all 😅🤣😂😅🤣😂

[@colleinbham1955]

Too funny!!!

[@lili-uj4sp]

[@jamesteichler1290]

Nice truck

[@troyrowlee4822]

Mine doesnt have a pink wire, out of 5 wires. So which one should I cut?

[@marshallweasel3454]

great idea, bypass the rev limiter so when you hold it wide open you'll have your minute of fun before your engine decides to blow up, and if you have a modern honda or yamaha 50cc, there's a little washer in the tailpipe, take a flat screwdriver and a hammer and knock it out, you get better airflow, also messing with the float valve on the carb won't do anything besides make the scooter a wee bit more responsive, and if you want power, buy a 100cc engine and just put a 50,cc sticker on it. or bore out the block to put a 80 cc piston in.

[@fuzedj5442]

How much more will you get out of it? I recently purchased brand new tao tao. Best i can read online its supposed to go 30mph it actually goes 35mph+. Im wondering if its worth toying with or should i just go straight to 100cc big bore kit?

[@grassmann028]

Although the look on people's faces when I was on a highway doing 60 plus miles an hour on a little scooter was hilarious

[@eliaslundstedt5607]

This being a 4 stroke 50cc, there is no way to get it going 100 kmh without having a really long gearing and a damn steep downhill and no electric rev limiter. My 2 stroke 50cc scooter, with a removed exaust plug and all other air flow plus gone as well, only tops out at 85 kmh, and that is really fast for a stock, 50cc 2 STROKE. Now Imagine a lousy 4 stroke

[@flyinbrian8630]

Will it work on my Alpha Sports Kaliber LS moped? The seat is a PAIN to take out. But uh yeah I think I found the CDI unit in the front near the headlight. It is a two stroke. So uh yeah if you could private message me the answer or just reply to this that would help a LOT thank you!

[@yolobaby3064]

im not sure wether or not you can do it with your type of moped but, what you have found near the headlight is a kind of voltage regulator that stops the headlights and indicators from blowing their bulbs. The CDI is usually located near to the battery as it was in the video however some are found underneath the plastics attached to the frame (usually with a cable tie)

[@WelkinAmv]

YOLO BABY Or under the seat on my two stroke Keeway Focus

[@thewatcher5248]

Never CUT IT REMOVE THE PIN SO YOU CAN PUT IT BACK AT ANYTIME

[@NyuuMikuru1]

According to modders, cdi and pollenators change might help if you follow basic instructions. I really do hate it when limiter limit my ride downhill.

[@SGHDRides]

if you out a switch on the Pink cable you can turn on the restriction when the cops are coming!

[@blackhatter011]

No but you can put a switch in. Out a switch will not work.

[@fulgonsta2765]

It's legal to deristrict a moped in the uk

[@stopn0ncents]

Mph/kmh goes off ur wheel speed so yes ...but I'm sure u have learned that within this last 6 years

[@albinosguy]

U lower the clip to richen it up n raise it to lean out

[@scottmiller3025]

Jeff Joy inflate some one else caught that too.

[@scottmiller3025]

dam spell check, I'm glad someone else caught that too

[@chrishorst6993]

What about the spring. I’m sure the metering rod needs to come out more to give a little more fuel. When you moved the clip up it put the lettering rod farther into the hole leaning it

[@_droid]

RPM limiters suck, all they do is keep the engine within operating tolerances so it won't break. Fuck that shit.

[@1Fotobook]

How much faster did it go after these manipulations?😊

[@setthestandardsimracing8689]

here in UK we have to buy these scooters RESTRICTED!!! this is exactly what my local dealer told me to do if I wanted to DE-RESTRICT my scooter, seen as I hold a full licence . maybe in US or other countries you don't have the restrictions but here in UK we do, good video ma man ignore the idiots trolling you... keep it up fella

[@roseevans1704]

carl stannard to derestrict a 50cc you need to be 17 years old or over hold a CBT certificate , provisional license no no dont need a full licence ride a derestricted 50cc scooter as for CDI you need adjustable unrestricted cdi all this does alter revs so to maximum revs for bike is allowed a mechanic which need do this

[@lukekalule6796]

Rose Evans it’s 16 years old*

[@albertoRODRIGUEZ-rt6ot]

everything in britian is restricted because you suck

[@keithburns5707]

Just wondering if any one thought to look at the head pipe for a washer?

[@mikehuntmotors]

raising the cuirclip on the needle reduces fuel, needs to be lowered. plus main jet changes and carb filters and exhaust changes need to be tried!
