Question
where i9s the oil drain on this bike

Answer
The older Harleys use a "dry sump" motor, which means the oil is stored in a tank separate from the motor. Look closely at the oil tank under the seat and you should find a drain hose or valve somewhere near the bottom of it - that is where you drain the oil from.
