Simson Tuning ZT-Tuning AOA mehr Leistung und Drehmoment bei gleicher Drehzahl S51 CO2radtechnik

Hello, Today we have another test with the ZT-Tuning AOA1 / AOA2 with adjustable counter-cone! We'll see if a shorter manifold and a modified counter-cone position can yield more power or torque at the same RPM. Attention! Please note that even the smallest modification to your vehicle will invalidate its operating permit!!! So, if you want to drive legally on public roads, use your vehicle in its stock condition or have the modifications officially registered. Enjoy the video! I'd appreciate your subscription ;-) To offer you a wider range of test and comparison videos, I would appreciate a small donation/contribution towards expenses: https://paypal.me/co2radtechnik?local... Since many of you have requested comparisons of different ignitions, exhausts, carburetors, cylinders, etc., which I simply can't buy all myself, this would allow me to offer more content. ... Since I don't need most of these parts myself, I'll occasionally hold a giveaway once I've tested them! #Simson #2stroke #CO2radtechnik
