Engine from idle if I blip the throttle it 1/9 times will switch off, and then I can hear ticking or beeping noise come from the engine for about 10 ish seconds, it also sometimes does not have power when rev matching the rev is choking as though the piston misfired or some valve like sound,


Duke 390 2018, recently fully serviced air filter, spark plug, fuel filter, oil, oil filter, screen, and coolant too. What could it be?




Thanks

Mine was doing something similar very poor idle and stalling when coming to a stop when cold and also a pain to start. I fitted a boosterplug and it has solve my issues so could be worth a look

Mine has done it a couple of times. I don't blip the throttle now and it hasn't done it since. No other running issues.

Yep. I quickly learnt not to blip the throttle when starting the bike. Press the starter, let go and let it do it’s thing until it starts.
