Thanks so much everyone, I've contacted all the sellers you posted.
Thing is though, $2500 is over the price of some used motorcycles, yet alone all used motorized bikes. For $2500, I could built a NEW Motoped (I already have a fork and other parts) which of course is built way better and more reliable. Or, I could get one of those wierd E-bike's which of course would be fun but not really useful.
That for me was the paradox of getting into motorized bikes...... You either have to be really cheap and get not-very-good chinese parts or love motorized bikes a lot to get good ones and spend more than you would for faster motorcycle. Well, just my opinion, so see ya' all round.
