Given the way the 2016 iteration is performing, one would logically expect that the factory team would go back to those specs (if indeed that is actually possible) and build from there. The question is, are there sufficient (if any) of the 2016 spec chassis available for the factory team? That and, how many sealed engines does the team have to present to scrutineers (all?) at the beginning of the season? If all those sealed engines are already stamped as inspected, then there is probably little they can do beyond electronics fiddling in order to go backwards, to go forwards. For me personally, it's painful to see Vinales who was in such great form at the beginning of 2016, flailing away. Tho he looked solid this morning in QP2 despite the way the rear end was jumping around like
a kangaroo milkshake.
