    Hello, currently my bike is running:

    Stage6 Sport PRO Variator - Piaggio
    Polini Sport Liquid Cooled 70cc Piaggio Cylinder Kit
    Stage6 PRO Replica Carbon Exhaust - Piaggio
    Carbon fiber reeds


    With the standard 17.5mm carb with a 72 main jet (was a 72main just when it had a 50 kit on). Currently dont have the money for a whole new carb so just making sure that me upjetting it all would help for now.
    Looking at getting the following:

    Dellorto 6mm Jets- Polini 80-98
    Dellorto Carburettor Needle Set (PHVA)
    Idle Jets- PHVA/ PHBN (Can't remember which size i would need)
    Polini Air Filter 37mm
