This is a common and similar problem on older bikes, especially those with vacuum actuate petcocks.

The petcocks are left on (or the vacuum operated ones start to leak.) and the older worn needle and seat allow it to fill the carbs and slowly contaminate the crankcase oil with gasoline.

Someone gets the bike out, fires it and rides it and destroys the bottom end.

Cheap insurance, checking the oil for evidence of gas in any vehicle.
