Hello together! I’m new here and I think I have a complicated/mysterious question… .. Last year I had a big customer service in a free workshop. This included: setting valve play, ignition plugs change (iridium), oil change, air filter change and a few more little things that belong to it. After the workshop visit came the holiday. After about 700 km my Yamaha FZ1 N year 2009 started to stutter without ABS. I arrived the mountain (pass) unfortunately n I had to stop the vacation. The workshop checked a few things. It is called in the fault memory, ignition oscillating Zyl. 1. So we switched the ignition coil to Zyl. 4 to see if the error wanders with. Mistake was gone for the first time. Now I have the problem that the motorcycle in lukewarm condition jerks briefly (Zünd oscillating?), but after approx. 300 m the phenomenon is gone and then comes no more. And in the motorcycle own error memory is also nothing more h I honestly don’t know what else to do or what to do.. ! The workshop has no concrete answer for me either. Do you have a advice / tip for me on this? I would be very happy about answers / ideas.
