I stand corrected the 660 standard is 188.31 psi, minimum is 163.57 psi and maximum is 210.5 psi.
on a 700 it`s minimum 55.8 psi,standard is 64 psi and maximum is 71.7 psi
I got this info from the Yamaha Service manuals. I thought the 660 specs were a typo but I have 2 different manuals and both state the same thing.
