Throat is common size for Kawasaki 2V sport bike motor at 85% of valve diameter if it's 34mm.
Punch throats to at least 88%. Push the seat all the way out on the face of the valve.
Punch exhaust throats to 90%. Push the seat out on the exhaust valve as well.
thanks for the tips larry
so not much to do about the strong "S" line in 1 & 4?
my concern is that flow cant really stick to the outside wall (the right wall in cyl 4 for instance) so essentially the effective section gets chocked there and most of the flow conitnues to the pocket space left of the valve guide
The other thing i was considering was raising the floor a bit around points 4-5 for some venturi effect at the ssr.
Stock valve size in the GPZ is 34mm BTW, both port entry and throat are 29mm internal diameter = 660 sq-mm

anti dive removed, holes shut, damper piston welded, re-drilled for stiffer damping.
aluminum axle spacers, also drilled up the second pinch bolt hole for better axle clamping
