Hi guys, I have a 1984 GPz 550 with 65 hp at (approx.) 10500 rpm. Since I have suitcases on it, which only allow up to 130 km/h, and therefore I do not need the maximum speed (196 km/h without a suitcase at all), I think, both camshafts to run around each tooth. I had done the experiment once with a Gpz 305, which has only 1 overhead camshaft to let it run around 1 tooth. Effect: Vmax sank by 20 km/h, but the torque in the lower middle The 550s doesn’t have a lot of suit anyway. So I think it makes sense. It’s possible; in case of doubt, of course, motor with wrench slowly flipping out. Is it legal, do I lose my insurance cover or something like that? Thank you for your opinion Uwe
