Good evening people I mentioned my problems in an existing post, but I think it’s clearer when I open my new post, so that it’s a bit clearer. As described above, my scooter just went out during the ride last week. Quoted text from me from the other post:”Hello people ? I cleaned up my Kymco KB50 today and I checked what he might have done at the last time. Air filter has to be new. (Zerfäll In the air filter housing are gasoline residues, normal? Spark plug is deer brown. Believe that is perfect or? I saw the two screws loose on the exhaust manifold and have fixed them again. Starter relay I have to make a new one. That’s where the housing is broken. Then I came across the CDI and I think that’s the problem. The plug connections are all in order only the CDI in itself is a Naraku Racing CDI. Have already met one or the other Because if you take a Racing CDI you don’t have to adjust other things differently? Carburettor is top, clean and no nozzles clogged. The spark plug is made of metal and not like you know it from rubber and inside where they are. Contacts are easily oxidized. Do I have to change it now? Again my data: Kymco KB50 50cc original exhaust I did not change it myself or did I change it again? Only new spark plug installed. BR8HS. One more question. Got on the exhaust, just before the pot comes, something like a small blind tube only with a screw on it. Only no idea what the screw is for. I hope you can make a small picture of what might be with it. Thank you in advance. Greetings and nice evening still Andreas R. ?” The scooter runs in the last days without it going out. It was only the one day he went out during the ride. I just just changed. I don’t want that one time it doesn’t run anymore and that’s why I’m collecting as much information from you as I can to eliminate the cause. I thank you very much for your pain and pain with the help of I’m still loading a picture of my spark plug.
