Hello, and that’s what I’m driving, already time a few weeks and tonight I was allowed to push because my scooter went out mountain at once and rolled out but why? After 1 minute he went on again and then after 30 m out again so first a smoked and waited afterwards he went on again but I drove about 30 at the traffic light he didn’t go on anymore and then the kickstarted clamped and he didn’t spin E-starter anymore. So home pushed Vario lid on screwed and I couldn’t turn the crankshaft anymore. I drive air-cooled what could it be? Too hot? And if I want to give full throttle it goes out Why?
