[Ragmas]

Okay, slide your pan up against your center stand.  Get a piece of cardboard say, 6 inches wide by about 8 or 10 inches long. This cardboard can act as a ramp beneath your drain plug using the center stand as a holder.  you basically rest the cardboard on the cross bar of the stand and stick it up far enough the the bottom of the motor and the crossbar of the stand hold it on place.  Throw away when done. 

I no longer have the center stand on my bike but that is what I used to do when I did.
