I don't use the listed pressures they are for the stock tires, the tires on my 675 at the moment are just barely removed DOT race tires, the cold pressures are 26/28 as a starting point, in fact on cold days I've run them a 23/24 to get them to 32psi hot where they are supposed to be.
Likewise my Speed Triple came with Bridgestones on it, its worm PR2s forever now. The pressures aren't analogousness.
What Bueller posted about the 10% rule is the best way to go about it.
