weeeeelll.. not to go splitting hairs as all your advice is on the spot
Kent, BUT - yamaha switched back to 4 valve heads on the mi motogp bike and
then the r1 street bike. real world utility was hardly the priority. =)

materials and manufacturing improvements, variable-length intake runners [i
bet those are fun to fix when they break], fly by wire, etc etc all made the
3rd intake valve not necessary. they can make all the power they need with 4
valves, so no need to add cost / weight / complexity. which i guess is
race-world utility!

 Yamaha, who introduced 5 valves to the motorcycle world, went back
