hallöchen.. I have a big problem… my mopped has an inspection behind it.. I myself am not a mechanic.. there I put them in the hands of friends who are… I myself just stood up with it.. Engine up.. Camshafts out.. Valves set.. Spark plugs are still in order to me (5000km)… Air filter cleaned (K&N).. new oil… everything was built together again… everything looked very well… I also looked at it again that also all plugs etc. teder are connected… tank on it… joa and now she no longer jumps on… it only starts when I give light gas.. but as soon as I release the gas it goes out again… since she has an injection that regulates it myself I don’t understand why it doesn’t matter without giving gas.. and it runs very restless… maybe someone has an idea about the problem.. mfg
