Some have experimented with it in the past, even in the racing - LPG powered boxer:
But one of the biggest prob with 2 wheeled vehicles are the high-pressure gas tanks that can pose a serious security threat - you can't hide it inside the secure place between the frame as on the 4 or more wheeled car.
The convert prodedure from petrol to LPG is relatively easy tho., but fiding a secure solution for the special gas tank can be complicated on a bike. In some countries finding LPG stations can be a bit hard too, but while some have LOADS of them.
