Hello Together I wanted to revive a KZ650SR and did most of it. This machine actually had an engine of the D variant (contact ignition) installed in the original. Then the previous owner of the engine was replaced by the engine of the F variant (contactless ignition). The wire harness was adapted to this. When I picked up the machine, it had power. The engine ran … although … well. Now it’s like that I always have the following problems: The engine runs some Z … then the current is off. Wants to say: nothing is going on anymore. No lamp, no ignition, no glimm lamp … nothing. Safety is okay … before and after the fuse is voltage. I now change the controller .. everything is going on again. So the controller is defective. BUT: After an uncertain time x … the same happens again. The machine has not been driven a meter yet … we only talk about the test operation in the stand. In this way I have heated up 3 controllers so far. The only explanation is that the only I now have an ironing that the controller that is installed with me (it has a cable bundle with 6pin plug, but with only 5 connectors and separately a cable with single connection …see pictures) does not fit the F motor. Therefore, my question: – Does anyone know if the controllers of the motors with contact ignition have different values than the controllers of the motors with contactless ignition? If yes, which please. – Does anyone know if the controllers of the F motors have the same connections as those of the D Mot oren (see pictures)? If no, can someone please send me an image of such a controller for the F motor? Ideally also with type plate/exact designation and connections? – Does anyone know how the harness of the SR (formerly D motor) would have to be converted (concretely) so that the controller fits for the F engine variant? If this is necessary. I hope I can solve the problem. Would the machine not like to give in to the parts recycling. Thanks and VG Tom
