tbh if you havnt done anything mechanically with a scooter before i highly advise against doing this as your first.

just get a garage to derestrict it for you, if you take it to the dealer you got it from he'll probably charge about 70quid but because you bought it from that company it shouldn't invalidate your warranty

im not going to pay for something i can do myself.

p.s i have worked on cars before so i am not a novice to using a spanner.

Mate... you want to drill holes in your airbox so it sounds better... tell me, when does a moped EVER sound good? It's only 60 odd quid to derestrict, so you may aswell pay... And one more thing, dont trust the clocks, usually 30mph, is 30mph on the clock, but once your speed starts to climb, they go further out. My friends Runner does an indicated 70/75, sometimes 80, on the CBR it comes up no more than 55mph.

why are you messing about with the airbox when i specifically told you how to derestrict it properly so you didn't fuck it up?

i think he's one of the 'if it sounds good then it must be fast' crowd

the kind that drive 0.6 litre 2cv's with baked bean cans welded to them

Yeah a friend of mine took a saw to the end of his exhaust. It is a tad louder.... Rolling Eyes

Apparently it now reaches 150mph, though there are no clocks. Go figure Laughing

mph is meters per hour in his case right?

Nah in all fairness it is a 600, a CBF600 to be precise, but it is still fairly ridiculous Razz

finally ive de restricted my ped. i did it myself and have removed the plate out of the variator (used a normal spanner but with a screwdriver to lock it so it doesnt move). i did the exhaust however i couldnt get a vice so i just hit it with a hammer against a brick which seemed to do the trick lol. if any one would like instructions etc just contact me.

thanks everyone for the help it is much appreciated.

I have a Speedfight 2 and I don't think it is de-restricted in the exhaust as it is pretty slow. Someone earlier mentioned removing a backplate, is this the backplate (circled)?

Also, somebody mentioned removing an extra chamber on the exhaust, is this it?

Thank you.

Please could somebody help me? If those aren't the backplate and the extra chamber then please could somebody show me where they are?

Just pay £60 and get it derestricted at a garage, then you don't risk messing up your ped.

I was just asking to see if my exhaust had been derestricted already, I am getting a sports exhaust soon anyway.

truslack · World Chat Champion Joined: 08 Apr 2007 Karma :

If it can do more than 35, the chances are yes - it's been de-restricted.

New question now. I have ordered a Leo Vince ZX sports exhaust for my Peugeot Speedfight. I have heard that they have restrictors in them to make them legal, so does anyone know how I take it out?

Catalyst · World Chat Champion Joined: 29 Nov 2006 Karma :

why buy a sport exhaust with restrictors in?!??! The whole point of buying an exhaust is to get one without them in, hahahahaah Laughing

Because then they are legal, and the restrictor is supposedly quite easy to remove. Anyway, I'm not 100% sure if it has got a restrictor in it, I have just heard that most sports exhausts do.

But thank you for your helpful comment.

Personally I think the best thing to do is keep your 50cc restricted or buy a 125cc. If you are 16 like me just wait until you're 17 and stay within the law. If you really want it de-restricting take it to the garage like everyone is saying. £60 is cheap compared to the Peugeot dealer near me that de-restricts for £100.

Hey dude...
You know what you are talking about so here goes. I bought a bike two years ago here in Spain, a 2004 Speedfight 2 LC and it was derestricted. All good except now I have the national bike test and it is going to fail. I got the plate that was taken out of the variator kit, refitted it and while the top speed is less now (60km from 90km) the acceleration seems to be almost quicker to me and I guess that it is still too fast for 49cc. Having read your post, I see that the previous owner chopped the exhaust so that explains why it is still too quick. Is there anything I can do short of buying a new exhaust?

Thing that makes me wonder is...he obviouisly did this years ago and it passed numerous tests since then, so how was that? Is it ok for the 49cc level with just the polate back in and the exhaust still hacked?

One more thing: I didn´t change the variator rollers. Should I, and which ones will slow it down a bit?

Thank you very much...

great, now you have restricted the wheel speed with the variator the engine will be doing 10000 rpm at 50kph and will wear out very quickly

you still need to restrict the engine, so fit a washer between the engine and the exhaust that makes the hole smaller where the gases from the engine go into the exhaust, this will stop the engine revving so high although you might have to experiment a bit with different size washers to get the max speed to where you need it to pass the test

Ok....im willimg to do that. And yes i noticed it was revving too high, even when i stopped accelerating it sounded too high.
So, thw point you are talking about is the join where the exhaust meets the engine, where it is bolted on? Is there a gasket at that point, and would i need to buy a new one? Any advice or directions as in the rough size needed would be a great help..forst timer at this, but ill put my hand to anything..
