How fast am I???

Meal @ all, would need the help of the MV6 drivers among you. In the course of my tachometer conversion on LCD I am not 100% sure if my KM/H display works properly. Would therefore ask you to see how fast you drive e.g. in the fourth gear at 2000 u/pm. Or at 3000upm in the fifth gear, or at 2000u/pm in the third, etc. Thank you and sunny greetings from Wuppertal MFG OLLI
