How to derestrict your scooter

I have just come across this video by Genuine, walking you through derestricting your scooter. I removed the exhaust restriction last summer, and got about 10 more mph. I can't wait to get my hands on an impact wrench and take the restricter off the variator!! http://vimeo.com/2575002

You remove the exhaust, from where it meets the scooter(underneath). Just drop it down far enough to remove the restrictor.

It's like a metal gasket, that funnels the air flow. There should also be a metal gasket too. It will be easy to see the diffence in the two. Leave the gasket and take out the restrictor. Then re-attatch the exhaust.

In the video it says to add a gasket, but I was fine with the one left. Just check to see if you are losing any air pressure from there once you're done.

My blackcat went 30mph with this restrictor in, and 40 with it out. I'm not a little guy(6'2" and 260lbs).

Good luck!! Let me know how it works for you.

Thanks for the info...

Is it the same procedure w/ the Rattler buck-ten? That's what I'm getting when I get home from Afghanistan.

I'm not sure. This was to deresrict any of the genuine 50cc models.

But it wouldn't hurt to look. If there is a restrictor there, take it out. It will definatley make a diffence.

The Rattler's not restricted, but you might think of modding it out! Very Happy

I just de-ristricted my daughters Buddy 50 which I bought from Jonlink from this forum...
One note that I will pass on is in the video the restricter washer looked metallic like those gold colored nuts and bolts you see sometimes...the washer in my Buddy was some kind of plastic piece. Anyways...just like the video, it was pretty simple...just make sure you have the lugged washer which lets you use the kick starter, engaged with the splines before you hand tighten the variator nut...I didn't have it engaged the first time and it started slipping when I started the scooter...I took it apart again and saw the lugged washer was not seated onto the splines....made sure this time, tightened it all up and moved on to the pipe restricter cone. That went like a breeze...except I couldn't get a socket over one of the nuts because the bent pipe was in the way slightly...a 10mm open end fixed that.
Next was the test ride....wow, what a difference! Went blasting up a hill up to 35 and it gets there quickly! On the flat 45 was reached very easily...even with my 275 pound butt on it! I'll wager it'll do 55+ on a long downhill now...we'lll see...thanks for the video!

So I just watched the video on derestricting my roughhouse. Couple questions:

1. Where can I buy an exhaust gasket after removing the restricted one? Size?

2. Will any rejetting have to be done?

3. When removing the variator can I use an manual socket wrench or do I need an the electric one as shown in the video?

I'm not much of a mechanic, but it looks pretty easy on the video and my dealer won't do it for me as it voids the warranty. Also if anything were to happen could I just re-restrict it before I take it into the dealer?
