Moin. I recently acquired a Yamaha XJ6 throttled by gasway limitation. I have now expanded this throttling and would like to have certified by the TÜV that it has been expanded so that I can allow it openly. However, the TÜV man did not want to do this for me, because he needed the expert report for the installation of the throttling. He would otherwise have allegedly no data about the motorcycle. Unfortunately, I did not have the expert report. Do you have any experiences? According to what I have read on the Internet, this is supposed to be an uncomplicated thing. Think about driving to a different test site. Greetings: I’m not sure if I have any problems with my computer.
