You don't need to have choke out long enough to wash gas into cylinder.  Pull choke at the same moment you hit the kill switch.  Use both hands, one on the choke knob. the other on the kill switch.  Only takes 1/2 second or less.

It is part of the savages charm

Mine was doing it all the time and my mates on thier big Victories like it cos they know I have arrived.

Proper tuning, the old fashioned way, as described previously will probably improve overall gas mileage, but may make the Lean Mean Environmental Machine raise an eyebrow.

If it can run at tick over slower by adjusting the throttle engine idler screw (left hand side - 'not the right hand under brass plug idle jet')

It may be enough, mine will give a quiet pufft, but if i twist the throttle to simulate fast idle I can give my calling card.

However rather than fiddle with choke on stopping, leave in gear with a bit of "almost biting but slowing the engine grip hill start style, flick the cut out switch, engage neutral. Side stand down cutout to normal remove key. Walk away from bike, return to bike to nswitch off parking light

I love this part of the movie- and Uncle Buck is so proud!!!

I laugh every time it happens to me.  Hey its characteristic.  Although, I might have to try some "fixes" to see if I can at least control when it happens (like letting it idle for a few seconds before shutting off)

I have not tried it yet (because I never remember) but I have heard that if you let the bike settle down to an idle and then let it idle for 20-30 seconds before shutting if off that it will not pop on shutdown.
