Hello everyone. Actually I come from the Yamaha corner. A friend has inherited a Honda CBF 600 SA, which stood about 3 years. Now she is standing with me to finish her TÜV. Since she ran modestly and took bad gas, I removed the carburettors and cleaned them. So far everything was good. A week later she jumped again bad. Shortly after that no longer at all. Now I pulled in the schematic and searched the Rep. book. After that should actually be on the ignition coil. f a cable 12V and on the other mass. But I can’t measure anything. Today we spent 5 hours limiting the error, but did not come to any result. Maybe someone still has a TIP.
