how do you know when to change gears in a manual car?

Answer 1

My old motorcycle didn’t have a tachometer, so I had no direct readout of how fast the engine was turning. People who were used to working with tachometers asked me this very same question, so I’ll tell you what I told them:

When it goes “EEEEEEEEE!” I shift up, and when it goes “Putt . . . Putt . . . Putt” I shift down.
