Arizoni is spot on.  That is why I needed to raise my octane because I now have cylinder pressures at 150psi.  And honestly, the stock bottom end can't handle anything higher than that.  So I'm flirting with disaster, but it makes life more exciting for me.  ;D

FWIW  I have always run 91oct in every bike I have owned since I was a kid and I very rarely have any fuel issues ever.
