Carburetor Kit 21 PHBG MotoForce Racing Minarelli vertical

Intake kit with carburetor yamaha BWs

This kit is ideal for anyone who wants to get the most out of their 50cc Minarelli vertical engine (Yamaha BWs, Slider, MBK Booster, Stunt and other models). Choosing the right carburetor and intake kit 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. The reed valve, carburetor, and air filter must also be perfectly matched. With this kit, all components are already precisely tuned, fully compatible, and ready to install.

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