Polini Contessa 2T Big Bore Kit for Yamaha Zuma Vertical Engine
The Polini Contessa 2T Big Bore Kit is a 72cc upgrade for the vertical engine of the Yamaha Zuma. It is meant for riders who want more output from their scooter without doing a lot of tuning work. Among the Yamaha Zuma scooter parts available, it can noticeably improve acceleration and power. It suits pre-2001 Zuma and BWS 50 models and is simple to fit and set up.
Installation Guidelines
Follow a proper break-in routine when fitting this big bore kit. Keep the throttle below full for the first 200-300 miles. Also add roughly one ounce of 2-stroke oil to the fuel tank, since the factory oil injectors do not provide adequate lubrication for a 72cc bore.
Important Considerations
This product is for off-road use only and may not be used on pollution-controlled vehicles in restricted areas. Check local rules before installing it, because the part is not intended for public roads or lands. Once bought, this kind of kit cannot be returned.
