Easy power can be had by reducing rotating mass. Get a lightened rotor, lighter chain, lighter rims, etc. For the engine, what have you done in terms of "standard mods"?
I had my wife's NSR250 Race bike making a good 63hp with very little effort (HRC Jetting, Exhaust, Open Airbox, HRC Wiring Harness). I should have retarded the damn thing, she had an issue with keeping it on two wheels
