Deristricting Vivacity 50cc

Seen an old post about deristricting the Vivacity 50cc but there were no pics or diagrams regarding the variator plate that needs removing.

Gonna open up and try to have a go at removing over the weekend, but would like it if someone had a manual/fiche or actual pics of the plate, what it looks like and how to remove it?

Had a local bike shop open it up and said there was nothing to remove. They cut and re-welded the restricter pipe on the exhaust but that has given me a boost from 32 to about 37mph. :?

Your help would be gratefully appreciated.

This is the video I used when I de restricted my moped, only a guide for one specific moped, but quite helpful for the general idea! Have a look, you can probably get to the next 4 parts by clicking the links on the video.

Thanks for that Pickledswede.

Think I've doen it and removed the right part......

see pic

Test ride now gets me over 45 on the downward bits :D

Bike seeming to make a more whinier noise now and smelling a little bit but assuming that is a mix of paranoia and bits going faster than used to!

There does seem to be a lot of potentially loose components though that aren't being contained any more by the plate!!

Ah well, let's just hope nothing catches fire!!! :?

uhhmmm plz tell me thats not the part you removed

thats the pate that holds the rollers inplace some people romove it thinking it will gain you more speed but i suggest you put it back
as in the end our rollers will fall out jam up your gear and throw you off tust me i know these things and have the sacrs to prove it
the peice your looking for is a metal ring some times however it is part of the variator system itself and needs replaceng such is the case in the kymco agillity 50 and super 8

if you want more help getting more power out of your bike pm me and ill point you in the right direction

Agreed, the part I removed was a washer in between the two conical plates, about 1.5-2cm thick

honda i STRONGLY recomend putting that plate back in

pickled its the same in all bikes an ally ring in the variator between the two conical plates easy to mistake as an important part the part honda has taken out though deffinately important in my opinion

Phew....thanks MS51

I was feeling a bit wary of the part that I removed and it all does seem a bit loose behind there, but even with this plate in place it was all a bit loose, but contained inside this plate!

There is still a plate that sits behind the rollers, with 3 nylon V shaped lugs/guides that let the plate slide up/down the shaft/cola thingummy.

Does anyone have manual/fiche pics that might help explain?

Is there anything I need to look out for or be wary of since doing this mod MS51?
