do you have to pull the engine speed up knob out to stop motor cutting out at idle?

reason I ask is a guy up road from me, bought a new triumph think same motor as yours, efi brand new, he wanted me to ride it the 200k home while he followed in his ute ( he had not ridden in years ) any way salesman said when it cut out idling after I first started it, that you need to pull this engine speed up out to stop motor cutting out. I said this is an efi and a new bike I expect the efi system to do all that. anyway 70k into ride home, stopped at a set of lights and motor cut out while idling, it was rthat quite and smooth at idle I did not know it had stopped. so had to keep revs up with throttle every set of lights. wondered if that is normal?

I'll dig up the pics when I get home, but I did like mine...until I got the Slim S and had to make room.
