With tuning cylinders, the standard shaft with its very short inlet time does not keep up. The bgm PRO shaft, on the other hand, closes on a PX motor housing approx. 65 ° after top dead center (this is different from the factory depending on the motor housing). The engine can be fine-tuned with these control angles. TIP: If the inlet is processed in such a way that the crankshaft releases the inlet slot earlier, additional power can be gained. A good value here has proven to be approx. 120 ° BCE. surrender. APPROVAL The crankshaft design of the PX engines is based on that of the first 125 cm³ engines from 1960 with approx. 5 hp.
