In order to adjust your internal rotor ignition, you’ll need either a dial gauge or a micrometer. We can offer this Motoforce micrometer with 0.1mm steps. It allows you to find the TDC and adjust the piston accordingly. This method is not as precise as working with a dial gauge, but on the other hand, the price is unbeatable.
Attention: M14 thread! Not suitable for scooters with M10 threads such as Peugeot Jetforce, Aprilia Di Tech / Factory, Gilera Runner Purejet, Piaggio NRG Purejet, Peugeot Speedfight 3 and GY6.
