This valve is a huge upgrade over the stock reed valve, as it has eight carbon fiber pedals, as apposed to the stock four steel pedals, providing a more atomized fuel mixture and crisper throttle response. If you're looking to add as much performance to your stock Scoot as possible, this is the way to go!Please be aware that carburetor adjustment and rejetting may be required for optimum performance.
