is it possile to install a speedometer and an rpm gauge on a 1985 Honda 200M??? if so, does anyone know how to go aout this???

 

all you need for an rpm guage is one of those quickie things that you rap the pickup wire around your spark plug wire..... lookup digital tachometers......
as far as the speedo, idk, i guess you could take a bicycle speedometer and put the pickup magnet on your front wheel and set it for the wheel's diameter.... but that might be inaccurate. get gps, thats what im using
