Welcome!!
I have a 05' People 50 and it's good for a solid 44mph on the flats (no head wind) but I don't know what sort of things were done to basically de-restrict it.
I would do just as zombie recommended, and read up on what can be done to remove restrictions and squeeze a few more MPH out of your scooter.
First of all, if it hasn't bee run much, toss a couple glugs of Seafoam in the tank to help clear out the jets and get things as clean as possible. 3 oz. or so will do fine, and then just ride it. I know it sounds like snake oil, but I've watched Seafoam perform miracles. It's available pretty much anywhere, including Walmart.
As far as what's needed to de-restrict it and squeeze another 10 mph out of it, someone else will have to chime in.. Mine has zero modifications.. Stock air filter, exhaust, etc, and as I mentioned, it's capable of just under 45mph.
