derestricting a sym jet euro x

[aidanh1]

Hi guys and gals
apeently on a sym jet euro x and other 50 cc bikes there are 2 main restricters one in the exhuast and one in the other big its a washer i cant remember what its called but you know what i mean does anyone have any videos or pics or explanation on how i derestrict my moped i dont want massive speeds but it only does 30 at a push so just want a tiny bit more speed for when i need it

That washer is located between the two halfs of the variator. It keeps them from coming together and getting to higher speeds.

As a general rule a 2 stroke can be modified to go very fast but there are a couple out there that can not be modified at all.

is there any pictures of what this washer looks like or how to remove it ?

[Rebel]

I am sure I can find some. Right now I am at work and looking for stuff on my cell phone and posting is a problem. I'll look when I get home.

[Rebel]

its not really a washer its a "wedding" on the varaitor
there might be shim washers in there but you do not want to take them out

if you search youtube for varatior washer there should be plenty of vids

but you have to take your cvt cover off
then you will have to take the front pulley apart
the wedding band sits on the drive boss for the varatior

This is on a GY6 motor, it may be a bit different than yours.




One other thing is that if your not getting to a decent RPM you can put lighter rollers in your variator and it will let the motor rev higher letting you go a bit faster.

ive looked at the video loads of times and it shows a with the washer and without the washer pictures but i cant see any difference where is the washer in that video i fink im going blind

[jmkjr72]

basicly the wedding band will not allow the sliding part of the varatior to close all the way up
so it wont allow it to go into high gear

[Rebel]

It is on the shaft between the two halves of the variator. Thia was a popular restriction several years back but it might not even be a problem for you today. Since you want more speed you might consider just replacing the variator with a performance one.

[aidanh1]

Ye deffinatly after more speed not too much though lol
i took the cover off today to look at the variator and on it theres the bold and then some kind of spikey looking washer then the big circle variator thingy now this bike's full name is already sym jet euro x race team now obv it isnt a racing bike it goes 30mph ... but im wondering would there be performance parts already on it but restricted in a different way? obviously im crap at mechanics and ive never botherd with machinery or motors or parts i dont no anything my fiancé says im crap at being a man lmao so does anyone on here have a SYM bike that might know the workings or know anything in detail about the SYM coz the internet when it comes to this particular bike is totally empty

I noticed when I was looking that the pickens are pretty slim for information on the internet with regards to Sym scooters.

I don't think that anybody else here is riding a Sym but most scooters are pretty similar to other scooters. You should post photos so we can see what you are doing.

The link flyangler posted is some pretty generic information that fits for just about everybody but it is worth looking at.

yeah we had sym in the us for a short time and carter brothers weren't doing a good job promoting them

then carter brothers warehouse burnt and they broke the contract with sym

its been over a year and its still iffy as to who is taking care of sym here in the us

so yeah we don't have a lot of experience or info on them
