From the FIM rulebook...
~~~~~~~~~~
2.3.7 Engine Durability
1) In the MotoGP class the number of engines available for use
by each rider is limited. For the 2010 season a maximum of
6 engines may be used by each permanent contracted rider
for all the scheduled <u>races</u> of the season. Should a rider be
replaced for any reason, the replacement rider will be
deemed to be the original rider for purposes of engine
allocation.
Each manufacturer is allowed 2 additional engines for the
exclusive use of Wild Card riders only.
~~~~~~~~~~
This says nothing about practice engines just the racing engines.
