The choke nozzle is mainly responsible for the amount of fuel supplied during the start-up of your motorcycle.
If it is too low, the engine does not respond well to the throttle during the cold start phase; if it is too high, faulty spark plugs can quickly result from an overly rich mixture, and the engine runs very unevenly.
