Welcome to Scooter Street! In this exciting video, we're going to show you a simple derestriction hack that will unleash the true potential of your Kymco scooter. If you've been disappointed with its sluggish performance, then this is the solution you've been waiting for.
Join us as we dive into the 2022 model 50cc fuel-injected Kymco scooter and uncover any hidden restrictions in its transmission. We'll explore the variator shaft, where we discover a stepped shaft that limits the pulleys from coming together fully. But fear not, we have the answer!
By replacing the variator shaft with a derestricted version, we'll allow the belt to travel out further, resulting in a significant increase in speed. We'll also take a closer look at the rollers, ensuring they're the perfect weight to allow the engine to rev optimally.
After reassembling everything, we'll take the scooter for a test ride to see the incredible improvements first hand. And the results? Well, let's just say that our customer went from a disappointing 52 kilometres per hour to an impressive 64 kilometres per hour!

What is that thing called which you take out and put in another one?
Variator shaft, spacer, hub.
My kymco agility (euro 4) is restricted on the ECU it’s an injection , what can you do about it ? I’m from Greece
Hi to all in Greece👋. You will need to replace the ECU, you can buy these from good parts suppliers in Europe.
Also change the variator or shaft. rollers and clutch.
I have the kymco super 8 50cc 2t it does around 60 kmh on level road.i bought the malossi variator will i get a 10kmh top speed aswell or does the 2t not have as much restriction as it has a higher top speed to the like
The Super 8 2T needs and exhaust, jetting, and transmission rollers, springs. The CDI will relieve the rev restriction. They are heavily restricted.
@scooterstreetau thanks guys. I bought the exhaust leo vince tt of you guys and going to re jet carbi. Hope this helps me in the hills. Haha do you sell the cdi aswell
@@kseriesdan9722 Ok good luck, dont forget the variator or rollers, cutch springs. Yes we have CDI.
Hello
I have Motron Ideo 50cc. The speed is 48km/h. Please, if you know, tell me how to derestrict it??? At least till 60 or 65km/h.
Thanks you !!!!!!!!!!
From the pictures it looks like the regular 50cc 4 stroke enine found in many Chinese scoots.
Check the variator , CDI and carby for restrictions. Ask your selling Dealer.
Hi I have a 2012 KYMCO like 50 it’s so slow I can only go 26 miles I checked but it don’t have a restriction on the transmission what else can I do to make it go faster
Ohh, that is slow. You should check the transmission including the clutch and belt. Several models had many restriction and you may also have significant wear on these parts. Look for an exhaust blockage and air leaks through the filter system.
I had the same procedure done on my 2022 Like 50 2T. I also got around 65km/h top speed. It's worth noting that the increased range of the belt also affects the rpms, especially on steep hills. Often it will only go 25 up hills that it used to do 40. Would swapping out to more lightweight rollers make it more rev-happy?
The belt can increase the rpm from the start it depends and what size you replace with. Lighten the rollers only by 10-15%.
@@scooterstreetau Thanks I will give that a try. I’m not too concerned if it sacrifices a bit of top end speed.
5.5 gram rollers and a 1500rpm torque spring (yellow) will sort your bottom end torque, so hills will be better but top end speed sacrificed a bit.
@@leonbasham8803 thanks yeah they ended up putting in 7 gram rollers and also serviced the carb and clutches. Now it revs just as hard as the day I bought it! Nice smooth acceleration too. Not sure about top speed yet but it gets past 60 quite easily.
@@jem587 wow so they went heavier? How has that affected the hills?
hello i have the gy6 50cc injection. max speed 45kmh and revs my variator is unrestricted. what can i do for more speed?
You need perfomance ECU to start. Then begin with transmission.
@@scooterstreetau my ecu is the delphi mt 05 if i replace it with rongmao unlimited its ok?
@@thunder732 You need to ask the supplier if it is compatible and unrestricted or adjustable..
@@scooterstreetau thank you
Does this work with 2020 kymco like m50
Yes.
Hey i have the 2015 kymco like 200i 169cc just wondering if this has the same thing, my bike says it can top out at 160kmh but only hits about 85 on a straight and 100 downhill sometimes, ive been told that changing my belt and rollers can be risky as i live in canada and have to order all my parts off amazon..
No it does not have this restriction. My car speedo says 260 but it only does 190 so don't go off the speedo digit.
85kph is far to slow for a 163cc so have it checked by a scooter Mechanic.
@@scooterstreetau thank you for your advice, it sucks but im basically my own scooter mechanic 😭 where i live most places wont even touch my scooter or look at it so im basically stuck on my own learnings, youtube, google and peoples advice so any help would be much appreciated, i do plan to start with buying new rollers and a belt as im almost positive mine has not been changed since 2017😭
@@scooterstreetau im also pretty sure for the way they send theses scooters out worldwide i am aware most of them are tuned down to "country standards" u could say so im pretty sure it would have something to do with my jetting for my fuel injector, this is all what i assume and if so im forsure not advance enough to deal with that
@@R3V3RT420 You can try to isolate the issue by finding the cause, does the belt roll to the top of the variator and to the inner most point of the rear pulley?
@@R3V3RT420 Check the air filter and make sure it is not oil covered.
Does this work on the kymco agility 50T four stroke?
Is there anything else I can do to make the current Kymco agility 50T to make it go 60 km per hour?
Yes, they Agility and Like are same engine.
@@murraywolf7284 Go down a very steep hill. No not much more apart from major ECU and engine changes.
Can I take my bike into the shop to do this if I don’t have a motorcycle license… will they still do it? QLD
Check with the shop .
That rubber hose connected to the transmission cover, mine got pulled out. Where exactly do I put it back?? Someone help 🙏
It connects to the front of the trans cover, a breather/cooler hose. Reconnect and hose clamp it in place, simples.
It just slides in the cowling, goes to nothing.
@@leonbasham8803 It sits in to the body and allows air passage to the CVT, look for a positon where water cannot enter.
Hello, I have a 2019 kymco super 8 street, with a injection engine. It has a max speed of 49 kmh and doesn't go any faster, I can feel the scooter slow down a bit when it hits the 49 kmh. The ECU has been reprogrammed to allow the RPM to go up to, I believe, 9000 (I'm not 100% sure, if the guy who did this for me did it correctly. But he says he did). And the variator shaft isn't stepped.
Any idea's on how to make it faster?
How was the ecu reprogrammed? The only way I kow of is too replace the ECU. I have never heard of reprogramming the factory ECU💥
@@scooterstreetau I live in the Netherlands, the official kymco dealers can buy an application to reprogram the ecu. But the guy who did it for me, he sells restrictors, told me he also bought that application so he could do it himself.
But I'm gonna try putting in a Polini variator set and see if that helps.
Wow that is great, I am unaware of this application. You will need to find out what is now restrciting the engine, is it the exhaust or the transmission?@@user-mx8dx9tt5v
@@scooterstreetau Well that the problem, I don't know how to 😅. I did replace the variatior today, and it does do 5 kmh (54/55 kmh) faster. So that's great. But I don't think that is the top speed.
I am gonna replace the springs inside the clutch and the bigger one in there. Not sure what it's called.
Is the exhaust really something that can restrict it? I didn't know that
Everyone replaces the exhaust on their machines because the factory exhaist are restricted and performance exhaust offers performance..@@user-mx8dx9tt5v
the thing you took out can you just take out the thing with paper idk whats it is in english
We removed the shaft.
my 2016 has oil in the air box.What to do?
Check the level of oil in the engine, adjust it just below the high mark.
Check the air filter foam or paper, clean or remove any oil, wipe out the air box completely clean of oil. Sometime oil is on the air filter so only absorb off the excess! Check and clean the oil breather hose, usually located running from the engine head to the front of the air box. 👌
Yeah um. Next time be careful to be really precise when replacing transmission oil.
Kymco likes to let any extra oil you put in for transmission to flow into the air box as a backup or something.
?@@somesortofchill
@@scooterstreetau Forgive me for not being very technical, but yeah. Long story short-ish.
For motor oil you can just pour and measure if you are unsure if you put enough or too little.
For transmission, at least for the kymcos that I've ownes and used. You have to be precisely putting was it something like 0.19L or something like that. And anything you put over that is going to overflow i to the air box.
The guys I've bought the bikes from had oil in air box when I bought them so the above is what I researched and found that out some years ago.
Ok interesting, as the transmission is not connected in anyway to the gear diff oil. The oil breather for the head is connected to the air box but not the gear box.@@somesortofchill
is that bike euro5?
Yes.
so basically you dont need to change the ECU settings
The best way to look at this is, if the variator is the reason you are restricted then change the shaft or the variator. So if the CDI/ECU is the restriction then replace the CDI. The CDI is a restriction to the RPM so when you require higher RPM (more speed for more upgrades) then change the CDI. An example is when you change the exhaust or fit a higher cc cylinder kit you will require higher RPM, so we change the CDI/ECU.
