Hello, My Speedfight runs only 50 km/h although all throttles are outside. The scooter turns very high and does not get over 50 km/h which is a problem for me. All throttles are developed and the scooter is perfectly tuned and runs 1A, but slow. Without throttles it should run easily faster. Also a sports exhaust without throttle is installed. Please help me maybe someone knows this problem. On the Vario , clutch it can hardly lie there I already almost all auprobated (weights, feathers, etc.) Greeting Dennis
