Also, I'd like to point out and question anyone who says they felt differences:
Did you change chips/flash your ecu to get the correct VRIS points? The KL31 VRIS and Curve neck VRIS are not wildly different, but they are a fair ways off.
4000 - 4800 - 6800
vs
3750 - 4250 - 6250
Whatever you end up doing - make sure VRIS points are set up otherwise you'll definitely feel that in your powerband
