I eventually performed the modification yesterday, it works well 60/62 kph on the speedometer. Very easy to do, the biggest job was to build a device to block the piston ; I used an old spark plug fitted wiith a bolt inside ...My son is very pleased to this big speed increase !!!

Thanks alot man, exactly the same on speedfight 3. did it today and made my top speed increase by 15 km/h

So that's how it works: the angular velocity of the rotor overcomes the centripetal forces on the rollers; they move out pushing the plate which increases the radius the belt takes around the plate increasing its linear velocity. The washers prevent how far the belt radius can be increased around the rotor thus limiting the linear velocity and therefore maximum speed; interesting and noted for when I get one of these scooters for Summer.

Thank you alot!! It was very helpful, i removed also that plate and from 45 km/h now it reaches 65 km/h !

thank you for this my top speed is perfect after this. Really helpful!

Thanks man, i gained 15-17kmh morr on my speedfight 2 from your tips❤

Just perfect, thank you so much

Thanks for video. It,s very clear.

Does this change how my moped sound? Will you be able to hear that the moped is trimmed if you remove the restrictions?

Good stuff mate 👌🏻

Great video! Do you know what is the size of the rollers in vivacity 3? I just bought one and want to derestrict it and change the rollers since they seam to be too heavy and the scooter starts slowly.

I tried to do this to my vivacity 100cc, but the centre of that axle looks like drilled at the centre and hammered with some kind of sharp tool to make it stuck, so I wasn't able to unscrew that bolt, even vith a piston stopper inserted into the cylinder. Maybe I was too afraid to use too much brutal force in case I could brake the piston. Do you have any suggestions how could I unscrew it in this situation? thanks in advance.

Thank u for every thing .

Nice video!!! Is this for the new vivacity peugeot? And is it diffrent by a 2 or 4 motor?

So you remove washers & the big metal plate?

impact gun is usually the best way to open it. Compressed air of electric. Of course it could be hard to find one. it's best not to use excessive force against the piston.

probably. Not sure. it's almost identical procedure in all brands and models.Sometimes the limiter could look different.

I just did it on a looxor 50 cc and now it doesnt speed up at all. The gas works 1/20 Times. Answers?

Thanks, was rly helpful. My max speed rose about 15 km/h.

Guna try this today on my vivacity 100cc

What size socket do I need to take of the nut ??

i removed the restrictor plate and still its not going all the way up on the vario and its only runs 50kmh so what to do? to make itt little bit faster

Hi! My son want a sp2 here in Norway. I understand that it sucks with 45-50 km/t So, after some googeling im not smarter. What would you suggest as a smart way to tune he's fb2? Without changing sylinder, carorator.. Thanks again

Is this on the newer 2008- vivacity?

Which rollerset is the best for vivacity 3 50cc

oma viva menee ny 80 kiitos tästä

do u drive whitout weights :o??? and how many grams if u have weights

Thanks man :-)

before you take the belt off, that thing who looks like a stuck brick should i take that off?

hey can anyone tell me if I can do this to a 4t vivacity peugeot I've looked all over the Web helppppp me please

Thank you

Hello my friene, does this work on a Peugeot Ludix Elegance?

Hi . Please can I communicate with you about this bike

Do u know the weight of the rollers?

So simple 👍

and how many km is now?

What year is that peugeot? Or is it the same way on every year? Cos i have like 2010 and pretty new with this stuff. I'm sry for my english if there is something wrong. Thank you for helpful vid!:)

I have a Peugeot Speedfight 4 (4t, 2v, Euro5) from 2021 and I had it done by the shop I bought the scooter from, they gave me the vario ring which is a plastic ring and they also tuned the original ECU to make it run faster, it's still restricted by the ECU at 58km/h but I want to change it again so the ECU isn't the restricting factor anymore but I can't find any information about my particular scooter and the videos that I find from Peugeot scooters don't match at all to my scooter which makes it even more difficult for me. If there's anyone who knows where to find any information about my scooter or a shop where I can buy parts for my scooter that would be very helpful to me, I'm looking online for months thinking that eventually other people would buy a new scooter which is the same one as I have but now that a year has passed I still can't find anything online, this is very frustrating because I don't trust the mechanic from the shop where I bought my scooter and as soon as the guarantee period has passed I'm not going to that shop anymore so I want to do it myself then but if I can't even find an online shop selling 3rd party parts or original parts even then it's pretty much impossible for me to do it myself making me dependent on some guy that I don't trust.

does this work on peugeot v clic?

Isn’t there another tool instead of a impact gun

New vivacity 4T. ?

just a question about how to unscrew the bolt at the center of the variator ? It is a14 mm bolt and when I try to unscrew everything turns. I see you use an electric wrench, but how to unscrew it with just a manual device ? thanks

Hey James I`ve just removed 6 washers from the screws (2 for each) and there is absolutely no improvement. My vivacity is slow as ever going 45 km/h. Do you have any idea as why would it be ?

kiitos

Hello, there is no risk of the belt out? its the same on the vivacity 125cc?

You probably already know this but because I am a scooter friend I would like to inform you that when an accident occurs which causes the insurance to pay big money to the other party involved you will suddently have a huge problem because of this little adjustment.

Great vid! But can't you just remove the washers only and then put everything back?

Thanks! it works the same on speedfight! mine does (60-69)km/h at flat surface!

Kun mä otan ton peltikiekon pois nii ei kuule ku 40/kmh ja jos se on siinä nii 50/kmh

do i need to check it if my motorcycle doesn't start?

Do you need impact gun for it or can you do it wihout ?

Can you put it back later so it goes back to the original condition?

how do you make it go 80?

Mitä piti tehä en tajunnu

You only need to get rid of the plate?

it's probably almost similar to all engines.

Miksi tuo rullakuppi tai se ei lähde irti vain vetämällä?

Kyä tunnistaa lausunnasta et on suomalainen

Should u change jetting if you do this

Vivacity 125cc or 50cc? Thanks

Does it work on all Peugeots

best way to strip the threads is to use this machine for tighten the nut

Missä se rajotin siis on
