Mines a 2011 and the place I got it from derestircted it.
I know they 82 jet and CDI was cut. not sure as the smooth boss but I am sure that is in there. Mine averages 38 to 41MPH on flats with no other mods depending on weather and wind.
As for people saying get bigger scooters to begin with that is nice in theory, but in my state you need a motorcycle lincense for anything over 50cc. So with the 50cc I can just have regular license. Granted most cops would not pull you over just to check license but they maybe an occassion that could occur (i.e. just happen to be speeding on bigger scooter or police check point which I have been through a couple in my car and they check your license.) I heard of people getting citations and at least one person having their motorcycle impounded for not having the motorcycle licensing (they couldn't ride it home and no one to come get it). Where I live in florida you also have to take a basic riders course before you can apply for motorcycle license so that is at least $200 for cheap one. Also paying for new license. Plus add in extra cost for the bigger scooter of a couple of hundred bucks.
Say on the low end you spend $500 more to get faster scooter that can do like 60mph thats great and legally drive it. Or I can buy a 50cc and spend about $100 to $200 depending on parts and get 45 to 50 MPH and be happy and still have $300+ in my pocket.
Besides I hope most people are like me and understand that 50ccs won't be super fast but would like to at least get them to work at their full potential and from what I have seen 45 to 50 seams reasonable with right components and still staying 50cc.
And if I need real speed I just drive my car.
The law is the same here in Maryland. I just drive mine to and from base which is like 7 miles. No motorcycle license and no motercycle safty course required for 49cc on base. That is the only reason i bought one in the first place instead of getting a ninja 250. We are also required to insure it and have a sticker instead of a tag. One time regesration sticker.
