We assembled a tuning kit ideal for everyday use for you: the Stage6 50cc Tuning Kit MBK Booster / Stunt (street-legal). Essential components needed for maximum power and reliability, combined as a kit for a very good price.


The kit includes:


With these components, you can get appr. 7hp - which is about 3hp more than with the original set-up! Moreover, fuel consumption will remain within reasonable bounds because of the 17.5mm carburetor included in the kit so you can ride your scooter every day.


To get even more out of this kit, we recommend using several jets and weights (between 4g and 6g) to find the best adjustment for your engine. You'll have to install slightly harder clutch springs and torque spring to optimize your variator.

    MotoForce Carburetor manual choke PHVA 17.5mm

    In Stock - Same Day Dispatch for orders placed before 2pm.
    MotoForce PHVA Carburetor with cable choke 17.5mm, available at Maxiscoot for a very good price. The carburetor is an essential component of your engine. That's why you should consider replacing your OEM carburetor, together with your original exhaust, so you'll have better acceleration and higher top speed. We also recommend getting a new set of jets (Dell'Orto 6mm jets for this carb) to be able to properly adjust your carb. Note: this MotoForce carburetor can only be used with engines with cable choke (not lever choke!). Learn More
