I'm in need of a service Manual for my 2020 z800 Ex and hopefully someone knows if the speedo can be calibrated on the 2020 z800. I've set my valves initially intake at 0.6 and exhaust at 0.4 and saw on the older models are at .06-.14 intake and exhaust at .11-.19. I've adjusted them to these specs and it has slight valve chatter at idle and clears with slight gas.
