My lady and I just purchased one(china brand) retro 49cc scooter online and can't wait for it to come in.
Does anyone know how much of a difference it'll make if i buy the big bore kit for it to upgrade it to a 75cc and getting larger piping for the exhaust and maybe a intake/high performance filter.

Also its going to be a theme bike so i hope yall dig it and will post pics of progress.
