Hello forum, I’m new here and hope I don’t make a mistake here the first time. I wanted to get a GPZ 900 R soon, but I have a few things to think about. First the motorcycle was built in 1989, that is 22 years old and ran a whole 200,000 km. The seller has renewed in front of about 10,000 km tires, brakes, Simmeringe in the fork, chain kit and cooling circuit. He also said that he probably had resyncronized it, whatever that means. Tips and experiences regarding the GPZ and what should I pay attention to during the test drive? I thank you already in advance MfG Eddie
