Dropped my bike on left side on a trail, no obvious damage, picked it up engine still running, went to ride off, stalled, kicked it over with the starter, a few puffs of white smoke, strong fuel smell, kicked it over by foot, no go, tried to clutch it, wouldn't start, removed plug, cylinder full of fuel, fuel had drained into case mixing with oil to the point of filling the oil sight glass and beyond, almost hydraulic locking the motor. The result was a five kilomtere push/tow sailor language hour in the rain. Bike was fine prior to this. any ideas?
