Looking to upjet my bike due to getting a sport exhaust, does anyone know what mm jet I will need to get for the stock Peugeot speedfight 3 carb and what jet to use as I am installing clutch springs and 4.9g rollers as well
you need to check what your original jet is and order a jet 10% larger for a sports pipe. Rollers and clutch springs will not have an effect on the jetting.
