There's quite a bit of residual oil in the cases.
A single cylinder engine will run as long as there's gas in the carb.
A trials motorcycle will idle for about two minutes on a bowl
full of gas. Of course it's still getting oil with the premix for
that time. I wouldn't run it WFO to get rid of the gas
in the carb, since it does go lean for the last few seconds.
