@Horton @dbutcher the reason behind my question was, in fact, a conversation I had with someone at the MC factory. We were not killing the main switch in the new MC because of it new location and relative inconvenience. It is under the removable (pop out) middle observers seat. The factory guy told me it is actually really important to shutdown the main battery switch everyday, because......the main computer is still energized and pulling engine sensor information that feeds into the computations affecting engine performance. As the temps and pressures, etc. swing down, those inputs are constantly being updated, computed, and fed into engine performance algorithms. They told me that I would/should probably see an impact on engine performance over a few day span of only cutting off at the ignition.
FWIW....those that have a 2021 MC, we removed the lock down friction post on the front of the seat and the metal "C" holder thingy on the rear of the seat; which makes it much less of a PITA for remove the seat to get to the battery switch.
