Go for it if the bike has been richened up there is no threat but if you feel excessive heat from exhaust you may need to richen it up a tad, but as most of your time you are in the top gears there should not be a issue, One question thou did you have the dyno guy remove the timming restrictions as if he didnt touch the ignition side of things you may want to go to a better base map and have it fine tuned on dyno to really get the full benefit of opening the secondarys if you want one send me your e-mail in a "conversation" if you like
