Did this video help you?

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 !!!

AZREDFERN: The rev limiter is there so your motor lasts more than 30,000 miles. Granted your scooter may continue to produce more power with more RPMs until a certain point, and no limiter gets you there. But most scooters have long stroke engines for low end power and efficiency. Down side to long stroke motors, they don't like high RPMs; and because most scooters have CVTs, they spend most of their time in the peak RPM. If you rely on your scooter as an essential mode of transportation, leave it totally stock and it'll last a lifetime. But at least find out where your power band ends, and install a tach. Also, running it lean WILL damage components over time. You'll burn a valve or melt a hole through the piston.

Jonaz: You're a bit wrong in the beginning of the video, because in sweden it's illegal to modify any performance increasing parts and need to be standard of the manufacturer.

Grow Big Or Go Home: Wow freakin waste of 8 minutes 

droid: RPM limiters suck, all they do is keep the engine within operating tolerances so it won't break. freak that crap.

Darrens Wildcamping: i was waiting for you take the ???????? needle not the thing lol he knows how to take his scooter apart but does not no the names of anything

Beau 88: Stupid, leaning your mixture alone will blow an engine , Definately don't know what you are doing. 

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

Peter Kapica: All you did was remove the rev limiter and thats leaning, not richening. If its a 2 stroke, the engine will seize very fast. If i were you, just buy a racing cdi and performance coils and plugs for it and that will make a small difference. Or if you got big bucks, upgrade the carb.

ElectricRides: Do you know much about the FZ6R ? 

Вадим Иванин: Хуйни ты намутил. Быстрее он не станет 100% Так как проделывал всё то же самое! И не только это! Так ты только собьёшь настройки и он станет ехать только хуже. Реально сделает его быстрее это ЗАМЕНА ЦПГ на больший объём, ЗАМЕНА карбюратора, ЗАМЕНА вариатора. ВООБЩЕМ хочешь что бы ехал быстрее МЕНЯЕШ ЦЕЛИКОМ ЗАПЧАСТЬ! А лучше просто не покупать это дерьмо а взять сразу 150сс.

karma lasseur: 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 

TheKnorkey: next time get a friend to help u with the filming 

jimnrel: before giving advice on doing this sort of stuff. Know what your doing. you dont know what the job of the slide needle. yes It might make it a bit faster because its now in a lean mix. lot of engines like running lean just before heat siezure takes over... Faster? compression, fuel, exhaust flow then vairator..... Why Im have a shot at this vid... One of my students followed you advice.... only to now replace cyl, piston and a heated conrod.... Lean mix in the tropics is a killer.

TheWoodart: Why Can't We REMOVE Bad Wrong Incorrect Vids Like This One!!!! OMGG WTF

harryapollo1223: That wire isn't always the same for every ped ..... could be used for something else just saying .....

mapbike: moving the clip up on the metering rod allows less fuel from main jet into the engine at low to moderate rpms and at wide open throttle the metering rod is alway far enough from main jet that it has no effect on the amount of fuel that the engine gets, sorry BillyUK but you are completely wrong about this and you can potentially lean an engine out more at aprt throttle and cause it to run hotter and be harder to start when its cold. lower the c clip on that needle and you richen the part throttle mixture and decrease the temp of the engine if its a bit on the lean side. for very cheapbyou can get a replacement CDI that has no rev limitation and actually advances the ignition timing about 4 degrees which help the engine make more power in it low to medium rpm range. increase main jet size in carb and install free flowing exhaust with a higj flow air filter on carby and you'll see a definite performance increase and you wont hurt the engine if carb is jetted correctly. You should either revise or remove the part in this vid where you're doing that useless carb mod. it could cause someone to hurt their engine, that isnt an improvement at all unless the engine is already running to rich because its being used in a very high elevation area where the air is thin.

Spyro: haven't you got restrictors in your exhaust? the cylinder

Finstaa: 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.

Focus Cardona: U move the clip on the neddle the wrong way to get more gas u nedd to move the clip down that way the needle will raise down richer up leaner

Denver Morgan: Ok where are my wire cutters lol

Leandro Papas: You suck man... delete the video LOL

Gary Johnson: if you drive your scooter at full blast when it is new, you will ruin the engine. If you don't go above 20mph the first 100 miles, the engine will last many years, probably. If you go full blast the first 100 miles, the piston ring is very tight in the bore hole. It will create a lot of friction and heat the borehole til it melts and rubs off, widens the borehole and then your engine is crap. You will lose compression because you freaked your engine, your engine will not have much power, it will die because it cannot maintain compression. Never remove the governor, doing so will ruin your engine. Loss of compression will mean bad gas mileage, also.

Potato Squad: I don't think i did it right, i got my pickle stuck in a tree.

biggunzcdb: The advice on the needle height setting by the E-clip is suspect, unless he is meaning to "Lean" the mixture. To get MORE fuel or to make the fuel curve "Richer" you should move the E-clip down thus lifting the graduated needle higher in the main jet venturi and dumping more fuel at lower engine speeds, these are "Mikuni" style carb.s the amount of air entering the carb inflates and raises the "slide" (the "Black thing" is a DIAPHRAGM" that lifts the slide) so a higher pin(IE moving the clip lower) setting will cause more of the graduated needle to be pulled sooner IE more fuel...This isn't rocket science people, anyone that can't see how these things work just by looking at them ,shouldn't touch them... I often leave the needle alone and just swap in a higher number main jet, they only cost .99c you get 5 jets for 5 bucks from Ebay ,and a "Race" CDI that require no cutting on your wiring harness and comes with a hotter ignition coil only costs about $19.99. My scooters do 65+ because i install the 2.80:1 rear gear ( versus the stock 3.30:1) $30 and the 81.3cc Big Bore Kit, but this guy probably doesn't have the skill to crack open cases and build engines like I do....

trickey57: So you don't need that spring you lost?

Sayem Alam: Plan b - how to derestrict your moped 

swektmaico: Raising the clip which is lowering the needle will reduce gas content in the mixture and lean it out.

kevin swithenbank: The main restriction on small CC engines I'm the UK is a metal ring In the exhaust port that narrows the diameter of the outlet port thus slowing engine. Lifting the "cir-clip" will make engine rum slightly leaner and yes a slight increase in power but at the risk of seizing the engine. You do not need to cut wires to disconnect the ECU meter. . I been making scooters go faster for over 35,years now and my advice is if you want more speed hang out at race events and talk to the mechanics working on lambrettas etc in the pits. They love it when young kids ask questions and show interest in tuning engines. Trust me you won't annoy them by showing an interest in what they are doing..advice off you.tube is at best contradictory and at worst is a con from a pickle ! ! 

spiderroot: You need to change the intake manifold mate. It as a crack on it. Nice video!

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

ryon hazen: you didnt even say the different in speed

john bard: Turn zoom off the camera dumbass, and like the other guy said DONT DO THIS I've built a similar engine and played with the settings of a needle just like that. He is a retard

James79561: leave it alone and enjoy riding it. Your not going to get much out of a 50 anyway.

aaron jones: where i live you don't need license and insurance. you just have to be 15 with a helmet or 18 without a helmet

MLud: I'm not sure why this guy is being berated for this... the CDI 'is' limited and will stop the scoot from going above a certain road speed as dictated by the speed of the rear wheel. This info is passed to the CDI via that pink lead. I've got a 2010 model VClic with the green loop on the CDI which is now cut and taped. The speedo now happily goes into the red on the flat (maybe an extra 4mph) and way into the red going down hill (speed depends on steepness of the hill). Previously it would have stubbornly stuck at the redline regardless. What derestricting the CDI will NOT do is give you more power. You'd need to change rollers and springs to help the scoot work in the power band (slightly higher revs) but even that doesn't strictly give it more power. Pull the pink lead and give it a try... you can always plug it back in again if you don't like the result! :)

Sean8033: I hear Sea gooooes aka sea gulls

Steven Lamphear: Thanks for sharing your 'hack'. Word of warning though...you want to raise the needle to richen the mixture. There fore move the spring clip to the next lower notch, which will raise the needle in the bore.

pitbikeboy98: Anyone know how to derestrict a pulse phantom 50?

Stitch Echo: Work with cpi hussar 50cc

chris walker: yall trying to get motorcycle speeds out of a scooter..bottom line is if you do perfermance mods the proper way to increase ur hp you will have put just as much money in your scooter as you paid for it..and who the hell wants to be on a scooter that does 80mph...NOT I

Ryno Hugo: I just want to know at 7:25 the white bit, does it not tourque in? my scooters carb looks exactly like that and just want to know do you only have to put the white bit on or kinda let it skrew into the groove? If im not mistaken the white bit also have a spring and if I just put it on looks like it could come out at any moment.

Tom Gallier: Mine doesn't have an adjustment. On the dykon49cc its just a 2inch or so pin that holds a while clip for the spring to seat on... Any ideas? I have a everyday driver I don't wanna put money into. This idea would a been perfect. Not sure if the taotao I'm building has this. But I will check

yellstrom: Do you have to mod the engine if u cut the cable? 

diane colenso: U dont know freak all theres a bjtmin he engin aswell

DAVID LEE: this is on an auto moped scooter what about a geared moped such as aprilia sx 50 do you not have to rejet the carb and the exhaust needs attention for deresrict it.

bliephoofd: Just spend some money in a new big bore cylinder head and a new carb and a new exhaust, way better then freak with your electronics

Zteve W: 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. 

heyitsmejason1: Bitch Grow up and buy a car

Jason Carmichael: What was the speed before and after? Did you look at taking out the washer holding the variator apart? (That is if your scooter has it)
