Stock for stock the roller rocker engine seems to make more factory claimed power 140 vs. 145. On the dyno they apprear to be equal to the old high port motors in putting power to the ground. I don't think they rev as high but noone know the limit, yet. Also they don't have as many internal parts available in North America yet. There may be more in Japan or even Aussi/NZ that we don't know about.
