Hello together, a bit of history. I now had a whole time getting worse and worse problems. And indeed it was so that the scooter about E start did not work at all at all, over the kicker already. At some point the warm bad went on until now at the end warm no more. Stupid coincidence , I looked for a bench and got a used Technigas exhaust offered to it, because I thought to myself a new one does not harm me since the old one has already been welded twice. he scooter again with E start, when he is warm but also not always with E rather with the kicker. Now I assume that the old one was simply dense and I had too much traffic pressure. But now to the actual problem which appears now. If the scooter so reaches the 60 KM/H according to Tacho (so +- 5 KM/H) (yes the original speed limiter is lamely laid) then it just goes out, then rolled and then he jumps again at about 30 KM/H, until then I can turn on the gas as I want ,ni x happens. What could be the problem here? I just wanted to disassemble the scooter soon and check everything and clean it if necessary. What is meaningful? Where should I put my main focus on it? CDI is about 1 year old, candle plug and cable 3/4 year, spark plug 1 month old. Thanks already for your help.
