Moin Moin, I have a Gilera runner sp50 c14 bj. 99 water cooled! Battery is new, spark plug + cable is new, carburettor is cleaned, battery is new, e-choke I have changed temporarily and you can clearly feel that it gets warm/hot on top of it. When I produce a vacuum comes gasoline and a spark is also watching at e start and kicker.. When I go to the scooter I can kick until the doctor comes. If I use the e starter I leave the ca 30 sec pressed un d all the time it comes slowly and starts. When it is on it also stays on. I can then drive without problems. The ignite candle is deer brown after a full throttle ride.. Everything is problem-free. As soon as it is on the scooter goes on hit over e starter and kick without any problems. At noon off and start driving in the evening again there is a problem there. The dipped beam, main beam and the tail light is out. However, brake light and blinker go. Someone an idea what I can test or has to do?
