Excellent! My thanks to Berker Peksag and Michael Dickens and the
other ticket participants.

The double cam chain setup on the 1980's DOHC CB750 was another one of
Honda's pointless engineering breakthroughs. You know the cycle (if you'll
pardon the pun :-), Wonderful New Feature is introduced with much fanfare,
WNF is fawned over by the press, WNF is copied by the other three Japanese
makers (this step is sometimes optional), and finally, WNF is quietly dropped
by Honda.
