are piaggio 4t CDI units restricted?

i have a piaggio zip 4t 50cc and it does 60kmh , some guy said the CDI is restricted?? is this true? and how do i derestrict it?
Thanks in advance

 

normally they need to be plugged into a computer at a dealers

 

what to see if they are restricted?

 

Yes they are. To derestrict you have to saw through the side of the CDI.

I did it on my old zip and it was much faster.

It was detailed in a PDF document somewhere.

EDIT: when I saw it, it was in a PDF but I have found it here: http://www.piaggiospares.co.uk/spares/news/de-restriction.html

 

and that wont fuck my bike up?
and what speed will it go?
thankyou

 

No it won't if you do it right.
And I'm not sure. Sold the ped about 2 years ago but I do recall it being faster.

 

can u give a few instructions please on how to do it right? thanks

 

It's on that page. It's very simple.

Measure twice, cut once.

 

at some sites they are selling standard CDI units restricted....

 

sorry for bringing this thread up from the dead. here is the PDF you where looking for

Its the very last page you need to see, However it looks a bit daunting, hack sawing the CDI unit, id much rather buy a derestricted one for about £30
