Bike crank but wouldn't start.

[max]

Pdedse makes a good point, it also would be worth a "throttle reset" ;
Turn the ignition on, wait for the meters to sweep and the fuelpunp to prime and then twist the throttle to fully open, close again and fully open again, switch off and try to start again.

No idea if this would work but it's easy to do and it might work.

As far as i know a full open throttle is used to clear or "evaporate" a flooded engine and normally inhibits fuel and ignition to allow the overfuelled engine to reset, somebody with better knowledge please correct me.
