Agree, however, the manufacturer claims it's purely cam profile. Have to give it a look on the dyno with my own eyes and see what we have. As flat as the curve is, I can see shifting just after hitting peak hp, but we'll see.

EDIT: Bike has LS rockers, Ti valves, Ti keepers, Ti retainers, hydraulic lifters, and beehive springs. I read that the beehive springs tend to give up softly. Anyone have any experience pushing beehive springs to their limit? How do they behave at the limit?
