Hi Chris, as you willl recall mine was the big airbox bike but, IIRC the other bike had a complete bottom end rebuild/blueprint, whereas mine was just heads/squish/valve timing, all things being equal (as were the power outputs) it would seem to me that the big airbox gave as much as the blueprint in terms of power? - if bottom end blueprint gives any increase?
Either way the bigger airbox gives a much better 'growl' particularly when shifting at 9k+.
