the crossbone is lean and the one i rode popped and back fired on decel straight from the shop, the O2 will adjust at cruising but will struggle everywhere else.
Also FI bikes seem to need the exhaust back pressure created by the baffles to run well, as least my nightster did.
i would look into getting a proper stage 1 fitted sooner than later with a fueler/slipons and air kit if its the Harley sound you want as a lean motor in the long run will suffer, you may also be able to get away with the down load but that will still be lean
nice bike by the way
