I have a chinese 150cc scooter here in the U.S. - although all Chinese bikes are painted with the same brush, some are better than others. If you do some initial service items, it should be fine. Change all original fluids, adjust all controls, tighten with thread lock all bolts (exhaust bolts notoriously loosen and fall off), and change to a good spark plug (although the one I got had a good one in it from the manufacturer). The other two items are a little more complicated... set the valves, and change out the auto choke (notoriously bad). The choke isn't as much a problem in the warm weather though. These are simple machines to work on, there are TONS of sites and tutorials online for DIY, and to be honest, the biggest pain in the you know what is stripping off the plastics to get to the guts. The one I have has sat unused for 8 months and started on second try. Not bad for a cheap-o P.O.S. from China.
