  1. Learn to ride a motorcycle. They don’t have a synchro gearbox so revs have to be matched with throttle blips going down the box and fast shifts going up. Do that downshift blip in a slow electronic throttle and it will grumble on you.

  2. Shifting too slowly especially going down the box makes for a jerky ride as the revs never match. It’s also much tougher on the transmission.

  3. Many engines retard spark timing at cold start to put more heat down the exhaust for faster catalyst heating.

  4. My 2007 Fiat 1.4 has an electronic pedal and throttle body. There is no sign of rev hang in normal use. However if you shift at high revs and get straight back on the gas, the ECU ignores the rapid pedal movement causing revs to momentarily drop. It’s not throttle hang it’s electronic induced throttle lag.
