Cold start button 1 is fitted on the bottom of the throttle valve
body.
The injection system extends the injection time if the engine is
cold and the outside temperature is low. To help the engine burn
the increased amount of fuel, it must be supplied with additional
oxygen by pushing the cold start button.
After briefly opening up the throttle and then releasing the throttle
grip again, or turning the throttle grip towards the front, the cold
start button returns to its original position.
