Carburetor Kit 21 PWK MotoForce Racing Minarelli vertical

Racing intake kit with carburetor yamaha BWs

This kit is designed for riders who want to unlock the full potential of their 50cc Minarelli vertical engine (Yamaha BWs, Slider, MBK Booster, Stunt and many other models). Choosing the right carburetor and intake system is crucial for optimum engine performance - not too big and not too small! A carburetor that is too small will overheat the engine and a carburetor that is too large will increase fuel consumption without increasing performance. In addition, the reed valve, carburetor and air filter must be perfectly matched to each other. With this kit, everything is already perfectly matched, compatible and ready for use.

The result: more power, improved throttle response and a more aggressive sound.
