If you want to rebuild that gy6 top end in your scooter for a lil bit more pep, then these springs are the way to go. They not only look cool but they can handle up to 11,000 rpms. With the right cam and a nice set of NCY stainless valves in a ported head makes a big difference in power. Now that my motor is running strong i may try to match a good set of gears up to it and tune the NCY variator for max power.
